- 1what is the GPWS catagorised asa TAWS
terrain awareness warning system - 2how are TAWS classifiedA - improved version
B - lesser version - 3what are some on the class B minimum alerts-reduced terrain clearance
- intermittent terrain impact
- premature descent
- excessive rate of descent
- altitude loss after take off
- descent to 500 ft above the ground - 4what can class b be used for in a non decision approachvoice call out at 500 ft above the ground
- 5what are the class A alertseverything from class B
plus
excessive terrain closure rate
flight into terrain when not in LDG config
excessive downward deviation from GS - 6what is required of class a TAWSterrain awareness display that shows either the surrounding terrain or obstacles relative to the AC, or both

Flaps position
ILS Glidepath (deviation alerts)
IRS (pitch roll yaw) - 14what are the outputs of the GPWS computermaster indicators (orange and red)
visual warnings
audio warnings - 15when will you get a visual indication on your PFDwhen it becomes a warning not a caution

- 73describe the EGPWSit is able to look ahead with a terrain threat display. It uses a database NOT radar
- 74is the EGPWS on all ac the sameno, each EGPWS knows the limitations of the specific aircraft, and can give indications based on that
