Distance from departure to destination 338 NM True track 045 W/V 225/35 TAS 120 kt What is the distance and time of the PET from the departure point?

A: Distance: 169 NM Time: 85 min
B: Distance: 218 NM Time: 85 min
C: Distance: 120 NM Time: 46 min
D: Distance: 185 NM Time: 72 min

 

 

 

 

 

 

 

 

Answer: C

PET (point of equal time)

distance to PET = (D * H)/O + H

D = total track distance
H = groundspeed home
O = GS out

D = 338 NM
H = 120 – 35kts (headwind) = 85
O = 120 + 35kts (tailwind) = 155

PET (distance) = 338 * 85 / (155 + 85)
distance = 119.7 NM = 120 NM
(120 / 155 (ground speed out)) * 60 = 46 min

The final reserve fuel for aeroplanes with turbine engines is

A: fuel to fly for 45 minutes at holding speed at 1500 ft (450 m) above aerodrome elevation in standard conditions.
B: fuel to fly for 30 minutes at holding speed at 1500 ft (450 m) above aerodrome elevation in standard conditions.
C: fuel to fly for 45 minutes at holding speed at 1000 ft (300 m) above aerodrome elevation in standard conditions.
D: fuel to fly for 60 minutes at holding speed at 1500 ft (450 m) above aerodrome elevation in standard conditions.
