Question

15. For an airport runway, the standard separate distance is 5 nautical miles. The leading aircraft speed is 150 knot and the trailing aircraft speed is 120 knot. What's the time (in minutes) between the two successive landing aircrafts if the distance from entry gate to the runway is 6 nautical miles? AT- 5 A: 3.1 120.3600 B. 4.1 C. 5.1 D. 2.1

Answer 1

Two air craft are lending which is leading and trailing aircrafts.

First leading aircraft have speed of 150 knot while trailing aircraft have speed of 120 knots.

Leading aircraft need to cover distance of 6 nautical mile.

time required to cover this distance:

t 6 * 60 150

t = 2.4min

Trailing aircraft need to cover distance of 6 nautical mile and 5 nautical mile eatra because 5 nautical mile is distance between two airccrafts. Thus total 11 nautical mile distance need to cover by trailing aircraft.

t = 11 * 60 120

t = 5,5min

Time difference

= 3.1min

(A) 3.1 min is time difference between this two aircrafts.
