NTSB Safety Recommendation — Aviation

Recommendation text

IT IS RECOMMENDED THAT CONSIDERATION BE GIVEN TO THE INSTALLATION OF A RED WARNING LIGHT WITH ADJOINING PLACARD IN GRUMMAN GULFSTREAM AIRCRAFT. THE PLACARD WOULD WARN THAT, WITH THE FLIGHT SAFETY SWITCH IN THE "EMERGENCY" POSITION, THE CRUISE PITCH LOCKS MUST BE MANUALLY REMOVED WHEN AIRSPEED IS REDUCED BELOW CRUISE. IT IS CONSIDERED DESIRABLE THAT THE LIGHT ACTIVATE TO A FLASHING STATE WHEN THE SWITCH IS PLACED IN "EMERGENCY," AND DEACTIVATE WHEN ACTION IS TAKEN TO MANUALLY WITHDRAW THE LOCKS.

In plain language (FlightFinder summary)

The NTSB advised the FAA to require a visual alert system in Gulfstream aircraft that warns pilots when the emergency flight safety switch is engaged. This warning should indicate that the pilot must manually disengage the cruise pitch locks as airspeed decreases below cruising levels. The system would flash while the switch remains in the emergency position and turn off once the locks are released, ensuring the action is completed.
