The two things needed to know for fuel?

Answer 3

Quantity

How much is being used (flow)

Question 4

What are the threats to effective in-flight fuel management are?

Answer 4

• Complacency
• Failure to comply with Company policy
• International Deviation from the planned flight profile

Question 5

What are the 3 primary categories of poor in-flight fuel management?

Answer 5

1) Operational
2) Legal
3) Financial

Question 6

When must fuel leak checks be made?

4 things

Answer 6

• Top of Climb
• Cruise
• Further checks
• Approach descent point

Question 7

What can a lack of oil do to the aircraft?

Answer 7

Effect engine bearings and may result in engine failure

Question 8

How can you tell the amount of oil is low?

Answer 8

When you have a high oil temperature

Question 9

What does falling RPM indicate?

Answer 9

A loss of power

Question 10

What instrument tells jet aircraft if the efficiency of their engines?

Answer 10

Exhaust Gas Temperature (EGT)

May result in fire if too high

Question 11

What PSI do hydronic systems run at?

Answer 11

3,000 PSI

Question 12

Why do hydraulics chose to run at PSI of 3,000?

2 things

Answer 12

Because less space required

Lighter weight

Question 13

When was the Ground Proximity Warning System created (GPWS)

Answer 13

Developed in 1970

Question 14

What does GPWS do?

Answer 14

Helps prevent controlled flight into terrain

Question 15

What does GPWS use?

Answer 15

Uses aircraft’s radar altimeter to determine height above terrain.

Question 16

What will GPWS do when close to the ground?

Answer 16

Make an audible sound

Question 17

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

Answer 17

True

Question 18

How does EGPWS work?

Answer 18

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

Question 19

What do TAWS soft alerts indicate?

Answer 19

An unusual situation but not yet critical

Question 20

What is a TAWS hard warning?

Answer 20

Indicates a critical situation which requires immediate and robust action

Question 21

What shall be confirmed when a TAWS is stated?

Answer 21

Check the pressure setting

Question 22

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.

Answer 22

T

Question 23

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?

Answer 23

Aircraft may not conform to the published missed approach procedures

Question 24

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

Answer 24

True

Question 25

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

Answer 25

To identify ground features.

Question 26

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

Answer 26

T

Question 27

When selecting autopilot what features/ parameters can they set?

Answer 27

``` Cruise speed (Mach no.) Height Climb and descent rates Turns Full landings ```

Question 28

What are the advantages of auto pilot? | 4 things

Answer 28

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

Question 29

What is the FLight Management System (FMS)?

Answer 29

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

Question 30

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.

Answer 30

T

Question 31

What is the Electronic Flight Instrument Systems EFIS?

Answer 31

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

Question 32

What are the benefits of EFIS?

Answer 32

Simplifies instrument scan Improves positional awareness

Question 33

What does the Primary Fought Display PFD combine?

Answer 33

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

Answer 34

T

Question 35

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