An aircraft when flying from A to B is found to be off track at the pinpoint shown on the diagram. The pilot calculates the track

error as 12 degrees and the closing angle as 8 degrees. By how much does the pilot have to turn to reach point B

• 12 degrees to the right• 8 degrees to the right• 20 degrees to the right• 4 degrees to the right

All R.A.F. Aircraft are equipped with a Direct Indicating Compass (DIC). Why is this?

• The DIC gives a reading of true heading• The DIC is the most accurate compass system

available• The DIC is reliable and need no power supply• The DIC is not affected by turns or

accelerations

Where are variation values at their greatest?

• At the equator• In the southern hemisphere• In the northern hemisphere• In polar regions

What principle does an inertial navigation system use, to calculate the position of the

aircraft?• It uses compass heading and doppler values to

compute aircraft position• The navigator must update the inertial

navigation system all the time• A gyroscope feeds position to the computer• It is set accurately on the ground and then

measures the accelerations in the fore, aft and lateral

Which of the following is not a component within a Gyro-magnetic system

• A turn/acceleration cut out switch • A gyroscope• A flux valve magnetic detector• A suspended magnet

In order to fly in a visual circuit a trainee pilot requires

• Visibility and cloud base conditions to meet the aerodrome controller’s requirements

• No wind• Good visibility and no cloud in the sky• Good visibility and no wind

Why does an aircraft take off into wind

• To take off at a lower airspeed• To decrease the length of take off run• To increase groundspeed at take off• To use the full length of the runway

The airfield has a covering of shallow fog. A pilot circling directly overhead, sees the runway lights clearly. However , on the

approach to land, he may have great difficulty in seeing some lights. Why is this?

• Runway lights are designed to be seen from high level only

• The thickest fog always settles at the end of the runway

• Fog is more dense, closer to the ground• Fog will appear thicker when on the glide

path, because the pilot is looking at a shallower angle

What problems can be caused by heavy rain?

• Heavy snow• Runway Visual Range• Thunderstorms• Restricted visibility and flooded runway

A flight briefing indicated icing conditions on route. The aircraft has no ice protection. What advice would you

give to a novice pilot.

• Plan a near route avoiding icing conditions, or cancel the flight

• Go slower because the icing will have less effect

• Fly above the cloud• Go faster because the icing will have less

effect

The latitude of a point in its distance measured in degrees and minutes

• From the true south pole• North or south of the equator• East or west of Greenwich• From the true North Pole

Dundee Is due north of Abergavenny. If their latitudes are 56 27N and 51 50N, how far apart

are they?• 277nms• 277kms• 323nms• 323kms

When RAS is corrected for altitude and temperature, it becomes

A gyro cannot be perfect, and so over a period of time it becomes inaccurate, this is called?

• Gyro rigidity• Variation• Gyro wander• Turn/acceleration error

Which of the following statements, about the gyro-magnetic compass is true?

• The flux-valve controls the speed of the gyroscope

• When the aircraft climbs or descends, the flux valve takes over from the gyroscope

• The gyroscope takes over from the flux valve, whenever the aircraft turns

As a compass nears the magnetic north pole, the compass detector will try to point at the

magnetic material inside the earth. This is called:
