Given the following information, assuming conditions stay the same, what is the ETA at DELTA?
BETA to GAMMA distance: 60 NM
Actual time en-route: 30 min
Actual time of arrival at GAMMA: 1240 UTC
GAMMA to DELTA distance: 34 NM
- (1) Calculate Ground Speed: BETA - GAMMA Distance: 60 NM
60 NM / 30 min x 60 = 120 kt
- (2) Calculate flight time Time: GAMMA - DELTA
Ground Speed: 120 kt
Flight Time B-C = 34 NM / 120 kt = 17 min
- (3) Calculate ETA at DELTA
