correct the answer.....
In ADF system, Goniometer
- combines the signals from fixed loop antenna and sense antenna
- effectively simulates a rotating loop antenna
- alternately selects signals from loop antenna and sense antenna
goniometer is used with fixed loop antenna....???????
When a compass is in the slave mode
- the azimuth gyro will wander uncompensated
- azimuth gyro will be corrected by long term monitoring of the flux valve
- the azimuth gyro is slaved to the annunciator or synchroniser circuit
what is this??
on power up, the IRS obtains position
- latitude from previous position
- longitude from previous position
- latitude and longitude from previous position
both long. and lat ????

A fire engine is approaching you with its siren on. As it passes you its pitch
- increases.
- stays the same.
- decreases.
Please write your comment here.
The fuel metering unit has direct inputs via
- only the EEC
- the EEC and the fire control handle
- the EEC, fire control handle and the engine master switch
EEC directly controls FMV, fire handle and master s/w is directly connected to SOV.

The Fatigue limit for steel is generally in the region of, compared to the static U.T.S
- 40%-60%.
- 60%-80%.
- 20%-40%.
the correct answer is 40%-60%.
This limiting stress is called the ‘Fatigue Limit’ and for steels, the fatigue limit is generally in the region of 40% to 60% of the value of the static ultimate tensile strength (UTS).
Extracted from KLM UK Engineering Notes for Module 6.
In a single acting propeller, blade angle is increased by
- counterweights and a feathering spring.
- CTM.
- oil pressure.
According my notes, i found out that both single and double acting propeller changes the blade angle using oil pressure. Can anyone explain to me why the answer here says counterweights?
