This training aid is intended to help pilots understand the phenomenon of tailplane and wing stall while flying in icing conditions. The training also explains icing certification rules. And it recommends cockpit procedures to mitigate ice induced stall in order to maintain controlled flight during unexpected icing encounters.
Much has occurred since NASA's original 1998 ice contaminated tailplane stall video. This film updates that training. Specifically addressing the reality that for the past 30 years most icing accidents were caused by wing stall versus tail stall. The FAA wants to make pilots aware that vigilance is necessary to avoid the low-speed stall accidents that occur in icing, especially with the autopilot engaged.
The information in this training video supersedes, supplants, and replaces the instruction in all previous NASA tail stall icing training videos.
