1) An island is observed to be 15° to the left.The aircraft heading is 120°(M), variation 17°(W).The bearing °(T) from the aircraft to the island is:
A 302 B 088 C 122 D 268
2) A Lambert conformal conic chart has a constant of the cone of 0.75.The initial course of a straight line track drawn on this chart from A (40°N 050°W) to B is 043°(T) at A; course at B is 055°(T).What is the longitude of B?
A 36°W B 38°W C 41°W D 34°W
3) On a chart, the distance along a meridian between latitudes 45°N and 46°N is 6 cm. The scale of the chart is approximately:
A 1 : 1 850 000 B 1 : 1 000 000 C 1 : 185 000 D 1 : 18 500 000
4) A ground feature appears 30° to the left of the centre line of the CRT of an airborne weather radar. If the heading of the aircraft is 355° (M) and the magnetic variation is 15° East, the true bearing of the aircraft from the Feature is:
A 310° B 130° C 160° D 220°
5) The constant of cone of a Lambert conformal conic chart is quoted as 0.3955.At what latitude on the chart is earth convergency
correctly represented?
A 66°42' B 68°25' C 21°35' D 23°18'
