105.1 State the difference between a barometric and radar altimeter.
1) BAROMETRIC ALTIMETER - uses pitot-static pressure to indicate altitude above sea level.
a) the scale for barometric altimeter starts at 29.92 inches in mercury
2) RADAR ALTIMETER - uses radio echoes to determine altitude above ground level. (Terrain)
105.2 Define the following terms:
1) AZIMUTH - Angle of position of bearing. (measured clockwise).
2) BEARING - Angle of position of object.
3) RANGE - distance to the target or station.
4) HEADING - the direction you are pointing.
1) True heading - direction measured by true north.
2) Magnetic direction - direction based on the 360-azimuth circle going counter clockwise (with the 0/360-azimuth radial aligned with magnetic north).
3) Relative direction - uses the current direction that an object is facing as the 0/360-azimuth alignment.
