- The magnetic compass is reliable only when:
- The wings are level
- The airplane is sitting still on the ground
- The is no turbulence
- All of the above
- Errors in the magnetic compass are caused by:
- Magnetic variation
- Compass deviation
- Magnetic dip
- Isogonic lines
- Errors in the magnetic compass are at a minimum:
- In North America
- At the equator
- At the North and South poles
- The magnetic compass is always in error
- In the Montreal area (45° North), accelerating on an eastbound heading will cause the magnetic compass to swing. The movement will be:
- Toward North, and smaller numbers
- Toward North, and larger numbers
- Toward South, and larger numbers
- Toward South, and smaller numbers
- In the Montreal area (45° North), starting a right turn from a northbound heading will cause the magnetic compass to:
- Swing to temporarily show more a westerly heading
- Eventually catch up
- Lag the turn
- All of the above
- In icing conditions pitot heat will improve the operation of:
- The vertical speed indicator
- The airspeed indicator
- The altimeter
- All of the above
Fifty years is not enough
