Q1. Find the distance between A (45S 120W) and B (45S 160E).
3394 – Formula: Departure = ChLong(min) * cos(Lat). ChLong = 360 – (120 + 160) = 80 degrees. In minutes: 80 * 60 = 4800′. Calculation: 4800 * cos(45) = 3394 NM.
Q2. Find the distance between A (60N 020E) and B (60N 080E).
1800 – Formula: Departure = ChLong(min) * cos(Lat). ChLong =
Q3. Find the distance between A (60S 045E) and B (60S 165W).
4500 – Formula: Departure = ChLong(min) * cos(Lat). ChLong = 360 – (45 + 165) = 150 degrees. In minutes: 150 * 60 = 9000′. Calculation: 9000 * cos(60) = 4500 NM.
Q4. Find the distance between A (20N 060E) and B (20N 070W).
7330 – Formula: Departure = ChLong(min) * cos(Lat). ChLong = 60 + 70 = 130 degrees. In minutes: 130 * 60 = 7800′. Calculation: 7800 * cos(20) = 7330 NM.
Q5. Find the distance between A (30S 065W) and B (30S 165W).
5196 – Formula: Departure = ChLong(min) * cos(Lat). ChLong =
Q6. Find the distance between A (60S 140E) and B (60S 165W).
1650 – Formula: Departure = ChLong(min) * cos(Lat). ChLong = 360 – (140 + 165) = 55 degrees. In minutes: 55 * 60 = 3300′. Calculation: 3300 * cos(60) = 1650 NM.
Q7. Find the distance between A (50N 080W) and B (50N 160E).
4628 – Formula: Departure = ChLong(min) * cos(Lat). ChLong = 360 – (80 + 160) = 120 degrees. In minutes: 120 * 60 = 7200′. Calculation: 7200 * cos(50) = 4628 NM.
Q8. Find the distance between A (50S 020W) and B (50S 165W).
5592 – Formula: Departure = ChLong(min) * cos(Lat). ChLong =
Q9. Find the distance between A (40N 030E) and B (40N 165W).
7584 – Formula: Departure = ChLong(min) * cos(Lat). ChLong = 360 – (30 + 165) = 165 degrees. In minutes: 165 * 60 = 9900′. Calculation: 9900 * cos(40) = 7584 NM.
