PLT510: Air Masses And Fronts
What code PLT510 covers, why the FAA tests it, and how to study Air Masses And Fronts before your checkride.
Recall weather - causes / formation
What this means for your checkride
An air mass takes on the temperature and moisture characteristics of the surface over which it forms. The boundary layer between two air masses of different characteristics is known as a front. As fronts move, the meeting of dissimilar air masses causes clouds, precipitation, and changing weather.
Most significant weather changes occur along fronts, so pilots must understand how air masses and their boundaries create weather.
Weather does not appear randomly; frontal boundaries between differing air masses are a primary cause of cloud and precipitation.
Where to study it
A code on your test report is an area of deficiency. An authorized instructor must review it with you and endorse that review before you take the practical test, and the examiner may revisit it during the oral. Study it until you can explain it out loud, not just recognize the answer.
