NTSB Safety Recommendation — Aviation

Recommendation text

THE NTSB RECOMMENDS THAT THE FEDERAL AVIATION ADMINISTRATION: PROVIDE GUIDANCE AND DIRECTION TO PILOTS OF ATR-42 AND ATR-72 AIRPLANES IN THE EVENT OF INADVERTENT ENCOUNTER WITH ICING CONDITIONS BY THE FOLLOWING ACTIONS: (1) DEFINE OPTIMUM AIRPLANE CONFIGURATION AND SPEED INFORMATION; (2) PROHIBIT THE USE OF AUTOPILOT; (3) REQUIRE THE MONITORING OF LATERAL CONTROL FORCES; (4) AND DEFINE A POSITIVE PROCEDURE FOR REDUCING ANGLE OF ATTACK. (URGENT)

In plain language (FlightFinder summary)

The FAA is asked to provide guidance and direction to pilots of ATR-42 and ATR-72 airplanes for inadvertent icing encounters. The guidance should define optimum airplane configuration and speed, prohibit autopilot use, require monitoring of lateral control forces, and define a positive procedure for reducing angle of attack. This recommendation is marked urgent.

This plain-language summary is written by FlightFinder to explain the recommendation above. It is not the official wording — the verbatim NTSB text is quoted above.
