Knowledge Requirement: Wind
Verified from official sourcesTP 15263 - Atmospheric pressureVersion 1Effective -Verified 23 August 2026
In plain language
You must understand how pressure differences create wind, how surface heating changes wind in the friction layer, and how local terrain or city buildings create specialized wind patterns (like land/sea breezes, slope winds, and urban wind tunnels).
Requirement as structured
RPAS pilots must understand wind concepts, including pressure gradients, friction layer changes, diurnal effects, wind shear, land/sea breezes, anabatic/katabatic winds, and urban airflow effects.
