16
Q

What will GPWS do when close to the ground?

A

Make an audible sound

17
Q

Terrain Awareness and Warning Systems (TAWS)/ Enhance GPWS(EGPWS) are mandatory by ICAO. True or False?

A

True

18
Q

How does EGPWS work?

A

Obtains aircraft position from on board navigation systems such as GPS and compares with the terrain database programmed into memory bank by manufacturer

19
Q

What do TAWS soft alerts indicate?

A

An unusual situation but not yet critical

20
Q

What is a TAWS hard warning?

A

Indicates a critical situation which requires immediate and robust action

21
Q

What shall be confirmed when a TAWS is stated?

A

Check the pressure setting

22
Q

Based on GPS position and it’s terrain database TAWS can also give the flight crew a colour coded visual display of the terrain and obstacles in the vicinity of aircraft.

A

T

23
Q

In the event of a missed approach being initiated because of TWAS/GPWS alert (plus wind shear alert or TCAS RA) controllers should be aware that?

A

Aircraft may not conform to the published missed approach procedures

24
Q

Aircraft have on board weather equipment, specifically designed for detecting bad weather. True or False?

A

True

25
Q

If a pilot tilts the aircraft’s weather radar to the ground what will it help?

A

To identify ground features.

26
Q

The aircraft’s weather radar may also provide information to the GPWS equipment

A

T

27
Q

When selecting autopilot what features/ parameters can they set?

A 
Cruise speed (Mach no.)
Height 
Climb and descent rates
Turns
Full landings
28
Q

What are the advantages of auto pilot?

4 things

A

1) Reduces workload
2) Ensures accuracy
3) Many factors can be considered
4) Reduces input error

29
Q

What is the FLight Management System (FMS)?

A

A database which integrates route planning and airport data with management and autopilot for flight optimisation.

30
Q

FMS optimises the flight parameters in terms of best fuel burn, speed, time weight for waypoints. Including “Top of Climb/Descent (TOC/D) and ETA. Monitors weather and TCAS. Failure of system would increase pilot workload.

A

T

31
Q

What is the Electronic Flight Instrument Systems EFIS?

A

A unified electronic display which has combined data from different sources of the A/C

32
Q

What are the benefits of EFIS?

A

Simplifies instrument scan

Improves positional awareness

33
Q

What does the Primary Fought Display PFD combine?

A

Attitude Director indicator (ADI) and,

Horizontal Situation Indicator (HSI) formats with ASI, Altitude, VSI, TCAS and other essential information.

34
Q

EFIS has a navigation mode which displays navigational data on a moving map.

Present heading, waypoints etc. Shown in real time.

A

T

35
Q

Usually a full set of vital mechanical flight instruments are provided as back-up in the event of EFIS failure
True or False?

A

True
