Q1. 1. An aircraft starts at position 10S 178E and heads true north for 600 NM, then turns 90 degrees left, and maintains a rhumb line track for 120Nm. What is its final position?
00°00’N 176°00’E – Leg 1 (N 600 NM): dLat 10°. New Lat 00°. Leg 2 (W 120 NM): dLong = 120/cos(0) = 120 min = 2°. New Long 178E – 2° = 176°E.
Q2. 2. An aircraft starts at position 10N 030 E and heads true north for 450 NM, then turns 90 degrees Right, and maintains a rhumb line track for 200Nm. What is its final position?
17°30’N 033°30’E – Leg 1 (N 450 NM): dLat 7.5°. New Lat 17°30’N. Leg 2 (E 200 NM): dLong = 200/cos(17.5) = 209.7 min = 3.5°. New Long 30E + 3.5° = 33°30’E.
Q3. 3. An aircraft starts at position 05S 170W and heads true north for 1800 NM, then turns 90 degrees Right, and maintains a rhumb line track for 100 Nm. What is its final position?
25°00’N 168°10’W – Leg 1 (N 1800 NM): dLat 30°. New Lat 25°N. Leg 2 (E 100 NM): dLong = 100/cos(25) = 110.3 min = 1°50′. New Long 170W – 1°50′ = 168°10’W.
Q4. 4. An aircraft starts at position 30 N 004E and flown on track 180 for 450 NM, then turns 90 degrees left, and maintains a rhumb line track for 250Nm. What is its final position?
22°30’N 008°31’E – Leg 1 (S 450 NM): dLat 7.5°. New Lat 22°30’N. Leg 2 (E 250 NM): dLong = 250/cos(22.5) = 270.6 min = 4°31′. New Long 04E + 4°31′ = 08°31’E.
Q5. 5. An aircraft starts at position 60N 010W and flown 600Nm on track 090, then maintains a track of 180 for 120Nm. What is its final position?
58°00’N 010°00’E – Leg 1 (E 600 NM): dLong = 600/cos(60) = 1200 min = 20°. New Long 10W + 20° = 10°00’E. Leg 2 (S 120 NM): dLat 2°. New Lat 58°N.
Q6. 6. An aircraft starts at position 60N 030 E and flown 600Nm on track 270, then maintains a track of 360 for 300 Nm. What is its final position?
65°00’N 010°00’W – Leg 1 (W 600 NM): dLong = 600/cos(60) = 1200 min = 20°. New Long 30E – 20° = 10°E. (Correction: 30E – 20 = 10E. Wait, 30E – 20 = 10E. The Feedback says 10E. My calculation says 10E.
Q7. 7. An aircraft starts at position 30N 005E and heads true north for 450 NM, then turns 90 degrees Right, and maintains a rhumb line track for 200Nm. What is its final position?
37°30’N 009°12’E – Leg 1 (N 450 NM): dLat 7.5°. New Lat 37°30’N. Leg 2 (E 200 NM): dLong = 200/cos(37.5) = 252 min = 4°12′. New Long 05E + 4°12′ = 09°12’E.
Q8. 8. An aircraft starts from A (30 N 020E) and flies 300 Nm towards East to B. from B it maintains a track of 360 and covers 1200 Nm. what’s the current position of the aircraft.
50°00’N 025°46’E – Leg 1 (E 300 NM): dLong = 300/cos(30) = 346.4 min = 5°46′. New Long 20E + 5°46′ = 25°46’E. Leg 2 (N 1200 NM): dLat 20°. New Lat 50°N.
Q9. 9. An aircraft starts from P(60 N 010E) and flies 300 Nm towards West to Q. From Q it maintains a track of 180 and covers 1800 Nm. what’s the current position of the aircraft.
30°00’N 000°00’E – Leg 1 (W 300 NM): dLong = 300/cos(60) = 600 min = 10°. New Long 10E – 10° = 000°00′. Leg 2 (S 1800 NM): dLat 30°. New Lat 30°N.
Q10. 10. An aircraft starts from P(60 N 160E) and flies 300 Nm towards South to Q. From Q it maintains a track of 090 and covers 900 Nm. what’s the current position of the aircraft.
55°00’N 173°51’W – Leg 1 (S 300 NM): dLat 5°. New Lat 55°N. Leg 2 (E 900 NM): dLong = 900/cos(55) = 1569 min = 26°09′. New Long 160E + 26°09′ = 186°09′ = 173°51’W.
