Q1. What map projection is used for the UK CAA 1:500,000 aeronautical chart series?
  • A.  Lambert Conformal Conic
  • B.  Mercator
  • C.  Transverse Mercator
  • D.  Polar Stereographic
Show answer & explanation
✓ Answer: A. Lambert Conformal Conic
UK CAA 1:500,000 charts use the Lambert Conformal Conic projection, which gives a near-constant scale and represents a straight line as very close to a great circle over the chart's coverage. Mercator is used mainly for plotting charts at low latitudes where rhumb lines as straight lines are more useful.
Q2. An aircraft's compass reads 180° while the magnetic heading (from the compass deviation card) should be 178°. What is the deviation on this heading?
  • A.  2°E
  • B.  2°W
  • C.  178°
  • D.  358°
Show answer & explanation
✓ Answer: A. 2°E
Deviation is the angle between magnetic heading and compass heading, caused by the aircraft's own metal and electrical equipment. Here the compass reads higher than magnetic (180° vs 178°M), so the compass has been deflected east of magnetic, giving 2°E deviation.
Q3. Why does maximum drift angle for a given wind speed occur when the wind is roughly a right-angle crosswind rather than a near-headwind?
  • A.  Because groundspeed is highest in a crosswind, exaggerating the angle
  • B.  Because the sideways (across-track) component of the wind is largest when the wind is near 90° to the heading
  • C.  Because the DR computer cannot compute drift accurately below 45° wind angles
  • D.  Because crosswinds always exceed headwinds in reported speed
Show answer & explanation
✓ Answer: B. Because the sideways (across-track) component of the wind is largest when the wind is near 90° to the heading
Drift angle depends on the across-track component of the wind relative to TAS; this component peaks when the wind blows roughly perpendicular to the heading. Near a headwind, almost all the wind acts along the heading, producing little sideways displacement and thus little drift.
