Pushing either master caution/warning reset switch silences the warning and fire bell except

A

Landing config
Autopilot disconnect
Takeoff config
Some aircraft over speed.

18
Q

Engine start message inhibited from engine start switch engagement until

A
  • engine reaches idle
  • start is aborted
  • 2min elapsed
19
Q

Start messages not inhibited

A
  • eng fuel val
  • Eng shutdown
  • Eng starter
  • starter cutout
20
Q

Warning inhibits

A

From nose gear extension during rotation to
400ft or 20 sec

If fire occurs during inhibit, EICAS mess, but no fire bell and MW lights.

A

Thrust set for TO
Till
400ft or 20 sec

24
Q

Landing inhibits

A

EICAS comm alert, selcal, ACARS, ATC, PRINTER
Not cabin alert although chime is inhibited

Begins 800ft until

26
Q

Alt alert inhibit

A

Gear down and locked

27
Q

Slat/flap position disagree with lever
Stab trim outside of green band C2B6 nose up only
Speedbraie bit in down detention
Parking brake valve closed
28
Q

Landing config warning

A

In flight
Any landing gear not down and locked
Flaps in landing position or RA below 800 ft

29
Q

Stick nudger

A

If flaps are in the retracted position and the a of a continues to increase, control column nudger moves control column forward.

30
Q

GPWS

Provides time-critical alerts for potentially hazardous flight conditions involving imminent impact with the ground

Voice call outs for situational awareness

Windshear

Inputs from

A 
ADC
IRS
ILS
RA
GPS
31
Q

GPWS modes

A
  1. Excessive descent rate
  2. Excessive terrain closure rate
  3. Alt loss after takeoff or go-around
  4. Unsafe terrain clearance while not on landing configuration
  5. GS deviation
  6. Height callout and bank angle
  7. Windshear
32
Q

Enhanced GPWS

A

Look ahead terrain awareness.

Compare airplane geographic position and altitude against an internal terrain database to predict and display potential conflict with terrain.

Requires inputs from GPS

33
Q

GPWS priority

A 
Windshear
Mode 1
Mode 2
Look ahead terrain warning
Look ahead obstacle warning
Mode 2 caution
Look ahead  terrain caution
Look ahead obstacle caution 
Mode 4
Mode 6
Mode 4 G
Mode 4 F
Sink rate caution mode 1
Sink rate after takeoff mode 3
GS mode 5
Predictive windshear caution
34
Q

Mode 1

A

Sink rate then

Pull up

35
Q

Mode 2 excessive terrain closure

A

Mode 2 A- not in landing config
Warnings continue until 300’ gained

Mode 2 B- flaps in landing position
Pull up if no gear, otherwise only terrain
200-789 ft

36
Q

Mode 3 Altitude loss after TO or GA

A

Greater than 150’, 25%
Dont sink aural replaced by too low terrain

Arms below 245’, active when gear or flaps raised.

Effective between 30 and 1330 ft

Caution when alt loss =10% of RA

37
