This video show the function of the EGPWS Enhanced Ground Proximity Warning.
Modern aircraft are equipped with a GPWS (ground proximity warning
system). The main purpose is to make the pilot aware of any unsafe
procedures close to the ground. Example: when it may be completely safe to
descent with 2,000 feet per minute at high altitude, it is certainly dangerous
to do so at low altitude. In this case mode 2 "DON'T SINK!" would come up.
EGPWS - the "E" stands for enhanced - also includes a three dimensional GPS
database to determine the aicrafts' position in reference to the ground and
obstacles around the aircraft. If the aircraft is landing at an airport, certain
triggers are filtered out to avoid false alarms all the time (aircraft has to be
low to the ground to land). Most of the airports are in the EGPWS database.
This one is not. So we get flooded with these false alarms although the flight
was perfectly safe! :
If the alarm comes off in IMC (in the clouds) it is an immediate full power and climb at best angle of climb speed!!!
Your comments and suggestions are always welcome.
