An aircraft at position N52° E004° is flying heading 090 at 400 kts groundspeed. After 15 minutes, its approximate longitude will be:
Answer: E006° — the aircraft has moved east approximately 2° of longitude at N52°
At N52°, 1° of longitude ≈ 38 NM. In 15 minutes at 400 kts, the aircraft travels 100 NM east. 100 ÷ 38 ≈ 2.6° ≈ E006°.
A radar display shows an aircraft track heading towards you from the east at a steady 5-mile-per-sweep rate. The track will be at your position in approximately:
Answer: The time it takes depends on the sweep rate — but at 6 seconds per sweep, 5 NM per sweep means 360 NM/min closure
At 5 NM per 6-second sweep, the aircraft is moving at 5 NM per 6 sec = 50 NM/min = 3,000 kts groundspeed — which is unrealistically fast, illustrating that sweep rate and NM-per-sweep must both be known.
Two aircraft are at the same altitude. Aircraft Uniform is at N51° E003°, heading 045. Aircraft Victor is at N53° E006°, heading 225. On what heading are the two aircraft flying relative to each other, and are they converging or diverging?
Answer: Reciprocal headings (045/225) — they are converging directly toward each other
Heading 045 and heading 225 are exactly reciprocal (180° apart), and the two aircraft are positioned with Victor northeast of Uniform — meaning they are flying directly toward each other.
An aircraft is given a heading change from 360 to 090. It turns right. How many degrees has it turned, and in which direction was the turn?
Answer: 90 degrees to the right — from north (360) to east (090) is a 90-degree right turn
From 360° (north) to 090° (east) via a right turn is 90 degrees. The question specifies it turned right, so the short right turn of 90° is correct.
On a radar display, an aircraft is at bearing 270 (due west) from a VOR beacon at 20 NM. Another aircraft is at bearing 090 (due east) from the same VOR at 15 NM. Both are at the same altitude. The distance between them is approximately:
Answer: 35 NM — they are on opposite sides of the VOR on the same east-west line
Aircraft A is 20 NM west of the VOR and Aircraft B is 15 NM east of the VOR. On the same straight line, total separation = 20 + 15 = 35 NM.
An aircraft is flying a standard rate turn (3 degrees per second). It takes approximately how long to complete a 180-degree turn?
Answer: 60 seconds — 180 degrees ÷ 3 degrees per second = 60 seconds
Standard rate turn = 3°/second. Time for 180° = 180 ÷ 3 = 60 seconds.
