Magnetic compass + Radio Altimeter

In the northern hemisphere, during deceleration following a landing in an Easterly direction, the magnetic compass will indicate

• an apparent turn to the South
  

• an apparent turn to the North
  

• a constant heading
  

• a heading fluctuating about 090°
  

During deceleration following a landing in Northerly direction, the magnetic compass will indicate

• no apparent turn
  

• an apparent turn to the East
  

• an apparent turn to the West
  

• a heading fluctuating about 360°
  

During deceleration following a landing in a Southerly direction, the magnetic compass will indicate

• no apparent turn
  

• an apparent turn to the East
  

• an apparent turn to the West
  

• a heading fluctuating about 180°
  

In the Southern hemisphere, during deceleration following a landing in a Westerly direction, the magnetic compass will indicate

• an apparent turn to the North
  

• an apparent turn to the South
  

• no apparent turn
  

• a heading fluctuating about 270°

The quadrantal deviation of a magnetic compass is corrected by using

• magnetized needles
  

• hard iron pieces
  

• pairs of permanent magnets
  

• soft iron pieces
  

The quadrantal deviation of the magnetic compass is due to the action of

• the hard iron ices and the soft iron pieces influenced by the hard iron pieces
  

• the soft iron pieces influenced by the geomagnetic field
  

• the hard iron pieces influenced by the geomagnetic field
  

• the hard iron pieces influenced by the mild iron pieces
  

A pilot wishes to turn right on to a southerly heading with 20° bank at a latitude of 20° North. Using a direct reading compass, in order to achieve this he must stop

the turn on an approximate heading of

• 170°
  

• 150°
  

• 210°
  

• 190°
