Concerning the entry of data into the CDU -
1 data which is required to be entered as mandatory information for the operation of the FMC is indicated by boxes on the corresponding line on the CDU screen, while data which is optional but not essential for FMC computations is indicated by dashed lines
2 data which is required to be entered as mandatory information for the operation of the FMC is indicated by dashed lines on the corresponding line on the CDU screen, while data which is optional but not essential for FMC computations is indicated by boxes
3 all crew data inputs to the FMC are mandatory for the computation of flight plan performance
4 the FMC is able to perform all functions without any crew data inputs, however data input by crew members will enhance FMC flight performance efficiency

Q

2 isolate the leak and turn off the bleed source to prevent structural damage
3 increase bleed air flow on the left engine to ensure adequate supply for anti ice operation

The TCAS system fitted to the modern jet transport category of aircraft is able to provide two main types of messages to alert crew to the presence of traffic in the area. These messages are traffic advisories (TA’s) and resolution advisories (RA’s).
The statement correctly listing the differences between TA’s and RA’s is -
1 traffic advisories provide about 40 seconds notice to crew about traffic which will pass close but not close enough to warrant flight path alteration. Resolution advisories provide about 25 seconds notice to crew about traffic which will not have adequate separation and a command to climb or descent at a minimum rate will be announced
2 traffic advisories provide about 25 seconds notice to crew about traffic which will pass close but not close enough to warrant flight path alteration. Resolution advisories provide about 40 seconds notice to crew about traffic which will not have adequate separation and a command to climb or descent at a minimum rate will be announced

Q

Large transport category aircraft are often fitted with several artificial devices to provide protection against various undesirable flight characteristics. The yaw damper is one such device designed to prevent the development of uncommanded yaw at high altitude and speed by automatic rudder input controlled by a gyro stabilised feedback system. There are two main types of yaw dampers in common use today, the parallel type and the series type.
The statement which correctly describes the difference between these two types of yaw damper is -
1 the parallel type yaw damper uses two independent circuits to provide redundancy and both circuits operate simultaneously in normal operation. The series type yaw damper uses one circuit at a time with manual switching required to activate the backup in the event of a failure
2 the parallel type yaw damper operates in parallel with the autopilot’s or pilot’s rudder inputs and so the pedals move when the yaw damper operates. This increases rudder loads and this type must be switched off for take off and landing. The series type operates without moving the pedals and may be used during all stages of flight
3 the series type yaw damper uses two independent circuits to provide redundancy and both circuits operate simultaneously in normal operation. The parallel type yaw damper uses one circuit at a time with manual switching required to activate the backup in the event of a failure
4 the series type yaw damper operates in series with the autopilot’s or pilot’s rudder inputs and so the pedals move when the yaw damper operates. This increases rudder loads and this type must be switched off for take off and landing. The parallel type operates without moving the pedals and may be used during all stages of flight
