48
Q

Assuming VHF L MIC is selected on the comm panel. How can the crew member talk with ground personnel without selecting the FLT position?

A

- VNAV SPD,
- VNAV PTH,
- FLCH SPD

Select TO/GA switch if pitch mode equals 4 letters:
- TO/GA

58
Q

To Engage A/T changing the active mode select?

VNAV
FLCH
or
TO/GA if GA is armed

59

changes from THR to THR REF

60
Q

61
Q

What auto throttle mode matches the corresponding speed mode of TO/GA?

A

HOLD, THR, THR REF

62
Q

What auto throttle mode matches the corresponding speed mode of VNAV SPD?

A

IDLE, HOLD, THR, THR REF

63
Q

What are the roll modes?

A
  • HDG HOLD
  • HDG SEL
  • TO/GA (ground track)

64
Q

There are two types of Pitch Modes, and they are?

A
  • Speed of Pitch;
  • Speed on Thrust.
65
Q

Speed on Pitch works with two logics that are:

A
  • Pitch mode selection adjusts thrust to fixed setting, than remains fixed,
    and
  • The Elevator (stab) adjusts to maintain airspeed.

The VERTICAL modes are:
- FL CHG SPD
- VNAV SPD
- TO/GA

And the A/T modes are:
- THR
- THR REF
- IDLE
- HOLD

66
Q

Speed on Thrust works with two logics that are:

A
  • Pitch mode selection sets elevator, than remains fixed in position,
    and
  • The Autothrottles continually adjust to maintain airspeed.

The VERTICAL modes are:
- VNAV ALT
- VNAV PTH
- ALT
- V/S
- G/S
- FLARE
- G/P (-8 only)

And the only A/T mode is:
SPEED

67
Q

Vertical Speed mode V/S
Displays selected in _____ ft/min increments.
And, has a range of -/+ _____

A

100 ft/min increments.

Minus (-) 8000 ft/min
Plus (+) 6000 ft/min

68
Q

FLCH SPD Logic :

A

An Algorithm set Thrust
in order to reach the the level in 125 seconds.

Autopilot servos adjust the elevator to maintain the IAS/MACH window selected speed.
