charts and speeds selection ATR 72 - 500
Fuel calculations for ATR 72 - 500
Taxi - 40 kg, large airports up to 100 kg
Distance multiplied by 3
Hotel Mode - 100 kg/h
Holding for 30min + 1 go around - 350 kg
Divert to Alternate - distance multiplied by 3
TAS for fuel calculations - 270 kts
Taxi on one engine as much as possible.
Before takeoff in cooler days, watch for engine 1 oil temperature, min
45 °C for takeoff.
After landing ,engine 1 feather position for 1 minute then shut off.
Flight LZTT / EPPO - 250NM, Altn EPWR - 84NM
250 NM multiplied by 3 gives 750 kg
Flight will take 1 hour and 5 min.
Taxi fuel - 30kg, it covers start up and Hotel Mode and taxi for at
If prolonged taxi is expected or significant hold with Hotel Mode
running assume 100 kg for taxi.
84 NM multiplied by 3 gives 260 kg.
Holding plus go around gives 350 kg.
Total fuel TAXI+TRIP+ALTERNATE+HOLDING gives:
40 kg + 750 kg + 260 kg + 350 kg = 1400 kg
1395 kg is the minimum required fuel for flight.
After landing in EPPO, You should have 610 kg, which is the minimum
fuel for the flight to alternate, so you can't land in EPPO with less
than 610 kg. It is advised to have some extra fuel for unexpected
Recommended extra fuel for at least 30 min of flight is 200kg.
Adding 200 kg to 1400 kg gives 1600 kg total fuel for the trip. After
flight in EPPO the plane should have 810 kg.
Unless ATC restricted, climb at 170 IAS to FL100, then in pitch
mode to planned level.
On all Cargo flights climb at 160 / 170 IAS. Watch minimum icing speeds in icing
If not weather restricting climb to highest possible level up to FL250.
If time permitting use PWR MGT in CLIMB mode during whole flight
(less fuel burn).
