The thrust that an engine is developing is held after what speed during takeoff roll:
80 kts.
Which statement is incorrect about the operation of the “Altitude Hold” switch as the aircraft climbs through 17,000 ft if the EADI annunciations is “VNAV SPD”?
The AFDS commands altitude existing when switch is pushed
The purpose of cooling doors (ram air doors) in the air conditioning system of a large jet transport category aircraft is to:
Regulate the volume of air passing through the heat exchangers
The function of the mixing valve in the air conditioning system of a large jet transport category aircraft is to:
Regulate the mixture of cold and hot air for distribution into the passenger and crew cabins
Isolation valves are used to:
Separate the pneumatic duct into sections
How is cabin temperature controlled when passenger load distribution is not even?
A zone temperature control system is used
Trim air comes from the:
Pneumatic duct
The function of the condenser in a vapour-cycle cooling system is to:
Transfer heat from the Freon to outside air
The cooling effectiveness of the heat exchangers is controlled by the:
Inlet and exit doors
The “THRUST HOLD” annunciation on the EADI appears at what speed during the takeoff roll:
80 kts
An aircraft may be fitted with a ram-air valve: This valve:
Should be closed during normal operations
On descent, the crew forget to adjust the cabin altitude on the normal controller to the destination port. As the descent is continued, the aircraft will descend to the same altitude as the cabin. If the descent is continued the:
Cabin will descend at the same rate of as the aircraft
A small increase speed in a slow flying jet leads to a small initial decrease in thrust because:
Difference between exhaust and intake velocities is reduced.
Taking off in rain in a turbo jet, the igniter pulse will be selected to continuous. In this case, the spark will be:
Low value at high voltage.
