Enhanced Ground Proximity Warning System

Question 1

How is he EGPWS tested?

Answer 1

The EGPWS is tested by pressing the switchlight. Holding the switchlight down for less than 2 seconds will initiate an abbreviated test. Holding the switchlight down for longer than 2 seconds will initiate the complete test.

Question 2

If the aircraft’s GPS systems are inoperative, will the EGPWS still function?

Answer 2

Yes, it will compare DME information to determine the aircraft’s position and provide terrain warning

Question 3

What indications will the pilot have when an increasing performance windshear condition is encountered?

Answer 3

WINDSHEAR will be annunciated on the PFD in flashing yellow, along with the Alpha Margin Indicator (AMI)

Question 4

When an increasing performance Amber windshear caution is displayed, will the autopilot disconnect?

Answer 4

No

Question 5

What indications will the pilot have when a decreasing performance windshear condition is encountered?

Answer 5

WINDSHEAR will be annunciated on the PFD in flashing red, along with the Alpha Margin Indicator (AMI) The windshear aural alert will be heard, and the autopilot will disconnect.

Question 6

What is the recommended recovery maneuver for an encounter with windshear?

Answer 6

• Set maximum thrust
• Ensure spoilers are retracted
• Follow the flight director
• Commands smoothly and precisely, but do not follow the AMI
• Do not attempt to regain lost airspeed until terrain is no longer a factor
• Do not change landing gear or flap configuration until the vertical flight path is under control and the AMI has been removed

Question 7

Is a FLEX takeoff permitted when windshear is suspected?

Answer 7

No

Question 8

Is a go around required when an increasing performance windshear is encountered?

Answer 8

A go- around should be executed if the windshear is associated with convective activity, otherwise it is at the pilots discretion and is not required unless the approach becomes unstable. Extra caution and vigilance should be exercised.

Question 9

When following EGPWS escape guidance, what should the pilot do?

Answer 9

• Set Maximum thrust
• Ensure spoilers are retracted
• Disengage the autopilot
• Climb at the maximum rate possible to gain as much altitude as possible
