A

OPT –The most economical altitude based on gross weight

RECMD – The most economical based on performance and winds

58
Q

What happens when you enter a VOR into the VOR ONLY INHIBIT of the REF NAV DATA page?

A

Only the VOR portion of the navaid is inhibited. The FMC will still tune the DME for DME-DME updating

The two CDU’s operate independently. A route change to one CDU does NOT change the other one.

66
Q

What do status messages indicate?

A

Status messages indicate conditions requiring crew awareness for dispatch

67
Q

If both EICAS computers, or both CRT’s fail, how can engine instruments be monitored?

A

If both EICAS computers fail, or if both CRT’s fail, the standby engine indicator (SEI) is automatically activated.

  • The battery / standby system powers the centre autopilot
77
Q

What can cause inadvertent load shedding on the ground?

A

On the ground, advancing the thrust levers into the take-off range with the engines shut down may cause inadvertent load
shedding of the utility busses to occur. Returning the thrust levers to idle, and then pushing the utility bus switches OFF, then ON will
reset the load shedding

78

89
Q

What happens to the inboard ailerons when trailing edge flaps are extended?

A

The inboard ailerons droop in conjunction with trailing edge flap extension from 5 to 15

90
Q

What are possible causes of the EICAS advisory message AILERON LOCKOUT?

A

The outboard ailerons are permitted full travel at low speed and locked out at high speed. The EICAS advisory message AILERON
LOCKOUT could mean:
- At high speed that one or both outboard ailerons failed to lockout
- At low speeds it may indicate that one or both ailerons failed to unlock

91
Q

At what flap settings in flap load relief provided?

A

If the flap placard limit speed is exceeded with the flaps in the 25 or 30 position, the flaps automatically retract to the 20 position.
When airspeed is reduced, the flaps automatically re-extend. There is no EICAS message to support this.

92
Q

What are the take-off and landing flap setting?

A

Flaps 5, 15 and 20 are take-off flap positions. Flaps 25 and 30 are landing flap positions. Flaps 20 is used for some non-normal
landing conditions

93
Q

Does the flap position indicator display leading edge slat position at any stage?

A

The pointers move to 1 when all slats are in the midrange position. The position indicator provides only trailing edge flap position
indications for all flap settings greater than 1

94
Q

What temperatures may be set in the cabin via the compartment temperature controllers in the Auto position?

A

You can set the desired temperature between 18 and 30 degrees

95
Q

Are the shoulder and foot heaters available at all stages of flight?

A

The foot and shoulder heaters are only available inflight

96
Q

What does the NO COOLING light on the equipment-cooling panel indicate? When is this light active and is this a considerable
problem?

A

The NO COOLING light is active only in the OVRD mode. It indicates that there is no reverse flow of cooling air through the E/E
avionics compartment after OVRD is selected. This is a considerable problem. The QRH states that normal operation of avionics and
electrical equipment that are NOT powered by the standby bus cannot be assured. Equipment on the standby bus operates normally
for 90 minutes. After 90 minutes, normal operation of essential avionics cannot be assured.

97
Q

Why is it normal procedure to leave the Bulk Cargo Heat selector in the VENT position?

A

The VENT position requests a higher temperature control range than NORM. VENT provides a temperature of above 18c, while
the NORM position maintains compartment temperature above 7c. The VENT position also turns on ventilating for the bulk cargo
compartment. Obviously important for livestock

98
Q

What does the cabin altitude MANUAL control do?

A

It is spring loaded to centre and controls cabin outflow valve position, when the cabin altitude selector is in the MANUAL mode. It
moves the outflow valve towards open or closed.

99
Q

What rate of cabin climb and descent is programmed at the index mark of the cabin altitude AUTO RATE control?

A

The index mark establishes approx. 500fpm climb and 300fpm descent

100
Q

When will the CABIN ALTITUDE light illuminate and extinguish during a non-normal event?

A

It will illuminate in RED when cabin altitude exceeds 10,000ft. It will extinguish when then cabin altitude descends below 8500ft
