Do A Better Engine Run-up

Editor’s Note: We’re pleased to welcome Ryan Koch to Flight Training Central. Ryan leads course development at PilotWorkshops and is the architect behind several of its advanced online training programs including the Engine Operations Course. An active instructor, he focuses on helping pilots understand not just procedures, but the systems and decision-making behind them. In this article, he takes a fresh look at a routine task most pilots rarely reconsider: the engine run-up.


Run-ups Aren’t Just a Ritual

You’ve done dozens upon dozens of run-ups by following the factory checklist by rote—and it works. But that checklist was designed when the airplane was, and for much of the GA fleet that means 50+ years ago. That’s before widespread per-cylinder engine monitors and before we’ve collectively learned as much as we have about how these engines misbehave in real life.

Here are a few easy ways to get more out of a normal run-up, even in a simple carbureted trainer.


Ignition Check

It’s better to think of this as an “ignition check” rather than just a “mag check.” You’re not just checking the magnetos here, but the entire ignition system: spark plugs, wiring, harnesses, and the switch itself.

With a digital tachometer, it’s tempting to chase the exact RPM listed on the checklist, but in practice that level of precision isn’t necessary. Most engine monitors have a “normalize” mode that levels all EGT and CHT bars at their current values and increases their sensitivity. Use that here, because the next step is watching EGT behavior as you isolate the individual magnetos—and normalizing makes changes easier to see.

When you switch to operation on a single magneto, all of the EGT bars should rise together by roughly the same amount. Rising temps may feel counterintuitive. The reason is that with only one spark plug firing, complete combustion takes longer. More of the burn is still happening later in the cycle, so the exhaust gas is hotter when it passes the probe.

If the EGTs don’t rise together, you’ve spotted a problem and learned something valuable. For example, if selecting the right magneto causes cylinder three’s EGT to fall instead of rise, the issue is likely related to the plug in that cylinder powered by the right magneto. That kind of information is far more useful to a mechanic than a vague report of roughness.

The most common issue you’ll turn up this way is a fouled spark plug, which typically presents as a drop in one EGT accompanied by engine roughness. Often you can fix it on the spot by generating enough heat to burn off deposits. Begin by setting a higher-than-runup RPM—something around 2000 RPM for most fixed-pitch propellers, or about 2200 RPM for a constant-speed propeller. Leave the ignition on the BOTH position. Then, lean the mixture for around peak RPM and leave it there for 30 to 60 seconds. This will feel like a long time, so set a timer. When the time’s up, return to the normal runup RPM and try again. If the problem persists, it’s reasonable to try just once more before calling it a day and calling your mechanic.

After the ignition check, be sure to return the key to the BOTH position. A helpful habit is using the sequence RIGHT, BOTH, LEFT, BOTH, so the final step is a single click back to normal operation.

Carb Heat

Applying carburetor heat normally results in a 100–200 RPM drop as the incoming air is warmer and less dense. The exact RPM drop varies by airplane, so know what’s normal for yours.

If you have a carb temp gauge, you can see direct evidence of this temperature rise. When aircraft are certificated, the FAA requires that carb heat cause a rise of at least 90°F at 75% power. In practice, you probably won’t see that much change—especially at lower runup power on an engine that hasn’t fully come up to operating temperature yet—but the rise should be enough to reliably take you out of the danger zone and melt ice in flight.

If the RPM drop is unusually small or the carb temperature doesn’t rise as usual, several things might be going on. There could be a leak in the carb heat system allowing relatively colder outside air to mix with the heated air. There could be a restriction in the normal intake, like a blocked air filter, that’s already reducing power and masking the difference. Or it may be that the carb heat door is not fully closing, leaving partial heat on all the time.

One practical way to guard against that last possibility is to make sure that when carb heat is off, the control reaches its mechanical stop before the knob reaches the panel. If the knob reaches the panel first, you can’t know if the carb heat door is actually closing.

Finally, it’s worth waiting 5–10 seconds with carb heat applied. If any carb ice has formed since engine start, you’ll likely feel some temporary roughness as the ice is melted and ingested, followed by smoother running and an increase in RPM.

Fuel

Fuel starvation and exhaustion remain leading causes of engine failure, and many are preventable before takeoff. Fuel gauges must be reasonably accurate and should confirm the amount of fuel you measured before flight. There’s a misconception that the gauges aren’t legally required to be accurate except when the tanks are empty, but that’s not true.

If you have a fuel totalizer, it can be an even more precise measure of fuel remaining—but only if it’s been initialized to the known starting fuel and calibrated properly. When it is, it becomes one of your best tools for managing range and reserves, so check it here.

Most Before Takeoff checklists call for the fuel selector to be on the appropriate tank. But avoid changing tanks right before takeoff. If the newly selected tank has a restriction or pickup problem, you may not discover that for several minutes—possibly right after takeoff when options are limited. Instead, select the proper tank before starting and verify it again before takeoff.


run up throttle

Ready for Takeoff

Many POHs will say something like, “The engine is ready for takeoff when the throttle can be advanced to full without the engine stumbling.” True—but how will you know until you try?

A good rule of thumb is to keep the throttle below 1000 RPM until the oil temperature is at least 100°F. On very cold days, you may have to compromise and use the runup to get there, but take your time and be gentle. Heating a cold engine too fast is a recipe for wear and tear and reduced longevity.


Do It, Then Check It

Following the checklist verbatim works great when you’re learning the steps. But once the steps become familiar, there’s a way to make them more effective. Work through the run-up from memory using a consistent flow pattern or simple mnemonic. Then, when everything is complete, pull out the checklist and verify that nothing was missed. Used this way, the checklist becomes a true backup and redundancy rather than a simple script to recite. You’ll also find you’re more mentally engaged in the process.

A better run-up doesn’t have to take longer than a basic one. It just uses the information available more intelligently—and gives you confidence that the engine is healthy before you commit to the takeoff roll.

From the DPE: Leveraging Study Groups

An old pilot once told me, “Study alone, fail alone.” He wasn’t wrong.

Aviation training is hard, and it is certainly easier when you have study partners. But too often, when I ask students during the practical tests I am conducting whether they studied with anyone else, the answer is “No.”

From student pilots grappling with basic aerodynamics to those pursuing advanced ratings like the Certified Flight Instructor (CFI), the journey is both exhilarating and challenging. However, one often underutilized tool in enhancing this educational experience is the study group—a collaborative learning environment that fosters mutual support, knowledge sharing, and practical application.

Study groups can be harnessed to propel all students toward success in flight training programs. There can be a symbiotic relationship between CFI candidates and lower-level students, where advanced learners practice teaching to gain invaluable experience. Peer-to-peer interactions in study groups can be utilized to capitalize on individual strengths and address weaknesses, creating a robust knowledge-sharing ecosystem. Building study groups in a flight training operation can cultivate a culture of standing study groups, complete with practical implementation strategies such as scheduled sessions, leadership by experienced instructors, and low-cost incentives to boost participation. By integrating these elements, flight training operations can build communities of learning, ultimately leading to higher retention rates, better exam pass rates, and more confident, competent pilots.

The benefits of study groups extend beyond mere academic performance. In aviation, where safety is non-negotiable, collaborative learning encourages the development of soft skills like communication, teamwork, and critical thinking—skills that translate directly to cockpit resource management (CRM) and real-world flying scenarios. Research from educational psychology, such as studies on cooperative learning, supports the efficacy of group study in enhancing retention and understanding of complex material. In the context of flight training, where subjects range from meteorology and navigation to FAA regulations, airspace, and aircraft systems, this approach can bridge the gap between theoretical knowledge and practical application.

Cultivating a Culture of Standing Study Groups in Training Operations

Creating a sustainable culture of study groups within a flight training operation isn’t hard. You just have to start. It doesn’t require lots of resources—just a place to meet, perhaps a projector and a computer, or a large monitor on which information can be shared. It does require intentional effort, though: a little structure to have a “topic of the week,” perhaps, and a push from dedicated leadership, CFIs, or even fellow students to make it happen.

The goal is to transform ad hoc gatherings into expected, integral parts of a flight training program. When this happens, a cultural shift is established that drives an ethos of collective responsibility for learning, where students anticipate and value coming together regularly. Such a culture can significantly boost outcomes, from higher FAA exam pass rates to smoother transitions between certification levels.

The foundation lies in setting standing sessions—regularly scheduled meetings that become routine. A best practice is to designate a specific night of the week, such as Tuesday at 6 or 7 PM, for 3–4 hours. This timing accommodates most schedules, post-work or classes, allowing ample time for in-depth discussions without exhaustion. Try to go with a Tuesday, Wednesday, or Thursday, avoiding Monday and Friday nights when many people have other obligations or want some personal downtime.

Sessions should be led by a CFI from the organization and focused on one or two targeted topics, such as airspace classifications or human factors, drawn from common student challenges or upcoming curriculum milestones. That might be the first part of the gathering each week, but then allow time later in the session where flexibility is key—opening the floor to emergent questions and ensuring relevance to all attendees.

You might have a set schedule of topics you flow through in these sessions, essentially creating a standing sequence that mirrors ground school topics.

Leadership by a CFI adds credibility and structure. The instructor might prepare some materials or leverage existing ones, such as videos, and use them as discussion starters. For variety, rotate CFIs or invite guest speakers, like air traffic controllers, for sessions on communications.

To encourage attendance, especially initially, employ low-cost incentives. Offering pizza, subs, or snacks creates a welcoming atmosphere, turning study into a social event. Provide a dedicated space, like a conference room at the flight school, equipped with whiteboards, projectors, and access to simulators for hands-on demos. Weekly consistency builds habit; promote via emails, apps like Slack, or bulletin boards, highlighting past successes to generate buzz.

Some flight training operations have even made these sessions “open to the public,” not just their own students. This can be used in some cases to recruit new students for a flight training operation.

A standing study session model fosters expectation: students plan around it, viewing it as essential as flight lessons. Over time, it cultivates ownership, with advanced students volunteering to lead subtopics. In larger programs, scale by offering multiple groups at different levels to ensure inclusivity.

By embedding standing study groups, training operations create a supportive ecosystem, accelerating pathways to success and preparing pilots for collaborative aviation careers.

Peer Support: Leveraging Strengths and Weaknesses in Study Groups

Beyond direct instruction from CFIs, the core strength of study groups lies in peer-to-peer collaboration, where students at similar levels help each other by leveraging individual strengths and addressing weaknesses. In flight training, where curricula encompass a broad array of subjects, no single student masters everything equally. Study groups transform this diversity into an asset, creating a supportive network that enhances collective understanding and individual growth.

At the heart of this is the principle of reciprocal teaching, where group members take turns asking questions, working through concepts, and learning together. For example, among a group of private pilot students, one might excel in meteorology due to a science background, while another shines in navigation from prior boating experience. During a session on flight planning, the meteorology expert could guide discussions on interpreting METARs and TAFs, helping peers who struggle with weather decoding. In return, the navigation whiz might clarify VOR usage, filling gaps for others.

Such interactions address common pain points in pilot training, like the overwhelming volume of information. The FAA’s knowledge tests for private pilots include hundreds of questions across multiple domains, and solo study can be frustrating. Study groups mitigate this by distributing cognitive load; members can divide topics, research independently, and reconvene to share findings. This collaborative problem-solving mirrors real-world aviation scenarios, such as crew coordination in multi-pilot operations, preparing students for future careers.

Moreover, study groups foster emotional support. The fear of failure—whether in checkrides or practical tests—can be daunting. Sharing experiences in a group normalizes struggles and reduces isolation. A student weak in aerodynamics might admit confusion over induced drag, prompting others to offer analogies or diagrams. This vulnerability builds trust and encourages active participation, leading to deeper learning. Educational research, including meta-analyses, shows that cooperative groups improve achievement by 0.5–1 standard deviation compared to individual study, particularly in technical fields. In other words, it works.


A Role for CFI Candidates in Mentoring Lower-Level Students (and Learning to Instruct)

One of the most innovative ways to leverage study groups in flight training is by involving CFI candidates in teaching roles for students at the student pilot or private pilot levels. This practice not only provides aspiring instructors with hands-on experience but also enriches the learning process for beginners by tapping into the advanced knowledge of their peers. CFI certification requires not just mastery of flying skills but also the ability to impart that knowledge effectively. By participating in study groups, CFI candidates can practice these teaching skills in a low-stakes environment, refining their instructional techniques before stepping into formal roles.

Imagine a typical scenario in a flight training academy: a CFI candidate, having completed their commercial and instrument ratings, is preparing for the Fundamentals of Instructing (FOI) exam and the CFI checkride. They possess a deeper understanding of advanced topics like aircraft performance charts, airspace, and weather information. In a study group setting, this candidate could lead a session, working with students to apply knowledge of these topics. For student pilots who might be struggling with basic principles, exposure to a near-peer instructor can help demystify intimidating subjects. The CFI candidate, in turn, gains experience in assessing student comprehension, adapting explanations, and handling questions—key competencies for their future career. This will make those CFI candidates more successful at demonstrating those skills on their CFI practical test.

From a practical standpoint, integrating CFI candidates into study groups can be structured to maximize benefits. Assign specific topics that the CFI candidate might be required to teach later, developing their skills to create a lesson plan, present material, evaluate students’ knowledge, and build their own teaching skills.

This not only hones their teaching skills but also fosters a sense of community in which lower-level students view CFI candidates as approachable mentors rather than distant authorities.

The experiential gains for CFI candidates are profound. Teaching forces them to revisit fundamentals, often revealing gaps in their own understanding. As they explain concepts like weight-and-balance calculations to private pilot students, they might refine their mental models, leading to better performance on their own exams. If the CFI candidate has already obtained their Ground Instructor certificate, they could even log this time for customers, providing a tangible incentive for those students to be part of the learning process for an up-and-coming CFI. Overall, this creates a pipeline of well-prepared instructors, reducing turnover and enhancing program quality.

By positioning CFI candidates (still with a senior actual CFI as a part of the sessions) as facilitators in study groups, flight training programs create a win-win scenario. Beginners accelerate their learning through accessible, advanced insights, while future instructors build essential skills.

The idea of establishing standing study groups in flight training operations—at local airports on your own, or just as a group of fellow students—should be a much more common practice.

Leveraging study groups in flight training programs offers a multifaceted approach to student success, from CFI candidates gaining teaching experience to peers supporting each other and building a culture of regular collaboration.

Start today if you are a flight training operation. Set a schedule for group study sessions. If you are a CFI or student reading this, and your flight training operation doesn’t offer it, do it yourself. Find a place, set a time, order a few pizzas, and invite some other fellow students who are working on flight training—no matter what type of training they are working on.

Private pilot, commercial pilot, instrument rating, and CFI students all need to know about weather information. We all need to know about airspace. We all talk about aircraft systems. Identify the overlaps among the different training sequences and share knowledge development with each other.

Start studying together for better success—and a little mutual support along the way.

I promise that the investment in time, space, and modest refreshments will yield dividends in student achievement. By embracing study groups, we empower everyone who is working on aviation knowledge development to soar higher, together.

How to enter the traffic pattern at a nontowered airport (video tip)

The FAA recommends standard traffic pattern flows at nontowered airports in an effort to maintain order and a safe environment for aircraft arrivals and departures. You’ll start by learning the basics of the crosswind, downwind, base and final legs, for the times you plan to stay “in the traffic pattern” when practicing multiple takeoffs and landings. You’ll also learn early on how to enter back into the pattern after spending some time practicing maneuvers at a higher altitude away from the airport.

This week’s video tip illustrates several methods to do this, depending on the direction from which you’re approaching the airport, in an effort to get established on the downwind leg at the published traffic pattern altitude.

Test Your Knowledge: Sharing Flight Expenses with Passengers

passengers

There are many nuances when it comes to sharing flight expenses with friends.

Private and Commercial pilots are permitted to share in the expenses of a flight with passengers. The types of expenses that can be shared are expressly stated in § 61.113(c) which are “fuel, oil, airport expenditures, or rental fees.” If you are to share in these expenses with other passengers, the pilot should not “pay less than the pro rata share of the operating expenses.” The pilot must also have a common purpose with his passengers for traveling to the destination. In other words, the pilot’s motivation cannot simply be flying as a favor or for the purpose of building flight time.

Scenario 1: You work for a real estate development company and are also a Private pilot who owns a Cessna 182 Skylane. Next week, you and a co-worker are traveling to a meeting that will be a two-hour drive. With a nice weather forecast, you decide you are going to fly instead and save a lot of travel time.

Scenario 2: You own a Cirrus SR-22 and are planning to fly the airplane to a concert with your spouse. You discover that another couple you know are planning to drive to the same concert. Given that you are close friends, you offer to pick them up in your airplane at an airport closer to where your friends live, and then drop them back off after the concert before flying home. Your friends graciously offer to share in the expense of the entire flight.

Sharing expenses Part 2 You got out of 1 right!

While you can be compensated to fly as a Commercial pilot, you can only do so under the common law term, private carriage, which is conducted under Part 91. The opposite of private carriage is common carriage which requires a Part 119 authorzation (Air Carrier Certificate) issued under Part 135 for charter operators or Part 121 for airlines.

An operation becomes a common carrier when it holds itself out (another common law term) to the public to fly any person or cargo who desires the service. Advertising is one of the most obvious forms of holding out to the public which can include social media posts, but the FAA has held that even establishing a reputation as one who provides his pilot services to the public is enough to be considered a common carrier requiring an air carrier certificate.

Scenario 3: You’ve just completed your checkride and earned your Commercial pilot certificate. But your checkride ran long and the DPE has another checkride starting soon at a nearby airport. The DPE offers to pay pay for the fuel if you can fly him to the nearby airport. After all, you have some time and he did just issue you your Commercial pilot certificate.

Video tip: how to fly with the Garmin GFC 500 Autopilot

Many training airplanes also include an autopilot in the panel, but it’s not something you’ll use much during primary training. After the checkride, though, there’s a real benefit in learning how to incorporate the autopilot into your flying. It’ll reduce fatigue on longer trips, and you’ll find it’s an integral part of instrument training should you decide to expand your skills and add an instrument rating.

This week’s tip looks at the basic features of Garmin’s popular GFC 500 autopilot, including how to turn it on and use airspeed, vertical speed, altitude and heading modes.
