An improved stable approach monitor (SAM)
system provides an audible advisory to a
pilot when an aircraft is on a final landing approach. More specifically, the SAM
system compares a measured
airspeed of the aircraft to a predetermined flap
placard speed. If the measured
airspeed exceeds the predetermined flap
placard speed then the improved SAM
system provides an audible advisory indicating the
airspeed of the aircraft is too fast. Advantageously, this audible advisory should prevent the
pilot from attempting to deploy the flaps at an excessive airspeed and in turn focuses the
pilot's attention on the problem at hand, which would be to reduce the airspeed of the aircraft. Once the airspeed is equal to or below the predetermined flap
placard speed, the improved SAM system may provide another audible advisory informing the pilot to commence deployment of the flaps.
