In aviation, change comes slowly from the FAA and sometimes more slowly from its users. The Lifted Index Analysis / K-Index Analysis chart was a useful product in its day. It has essentially become a relic of history but this twice a day product of historical data has been replaced with faster and easier to interpret products. Find out more here.

Many students beginning their training often ask the question…

Recently, the FAA formally announced that they would be removing a number of test questions from the Private Pilot Knowledge Test. These test questions included a number of weather related questions concerning Radar Summary Charts and TWEBs (Transcribed Weather Broadcast). This notice from the FAA got me thinking about these and some other weather products that have gone away in the last few years and what has come along to serve the same or a similar purpose. I’ll touch on the TWEB and Radar Summary Chart in this post and perhaps touch on some others in a future post.
