GNAV Flashcards
You are flying from G to H. You find that your position is 30 nm outbound from G and 4 nm left of the required track. What is your track error angle?
8°L
You are flying from E to F. You find that your position is 90 nm outbound from E and 6 nm right of the required track. What is your track error angle?
4°R
You are flying from N to P, which is a required track of 315°T. You find that your position is 40 nm outbound from N and 6 nm left of the required track. What is your track made good?
306°T
You are flying from L to M, which is a required track of 220°T. You find that your position is 45 nm outbound from L and 3 nm right of the required track. What is your track made good?
216°T
Track error angle:
Distance off/Distance to go
Track made good:
Track after adding/subtracting new heading in degrees
Closing angle:
Distance off/Distance to go
Combined track error angle:
Total leg distance/Distance flown x closing angle
An aircraft leaves A to fly to B, 95 nm distance. Having flown 35 nm, the aircraft position is found from a ‘pinpoint’ (a geographical point over which the aircraft has flown); the pinpoint is 7 nm right of track. What is the track error?
12°R
An aircraft leaves A to fly to B, 95 nm distance. Having flown 35 nm, the aircraft position is found from a ‘pinpoint’ (a geographical point over which the aircraft has flown); the pinpoint is 7 nm right of track. What alteration of heading is required to fly direct to B?
19°L
The distance A to B is 90 nm in a straight line. You are 60 nm from A when you fix your position 4 nm to the left of track. What correction do you need to make to arrive at B?
12°
Required ROD (3° GS) =
5 x Groundspeed (knots)
ROD
1° at 1 NM =
100 ft
Change in ROD (3° GS) =
5 x change in groundspeed
You are on ILS 3-degree glideslope which passes over the runway threshold at 50 feet. Your DME range is 25 nm from the threshold. What is your height above the runway threshold elevation? (Use the 1 in 60 rule and 6000 feet = 1 nautical mile)
3x (25x6000) / 60
