Applicable to:
Airport geometric elevation = 4 200 ft
TAKEOFF CHART DATA
Airport geometric elevation = 450 ft
QNH = 1 013 hPa

FCOM 19 AUG 10
Air conditioning OFF
EXAMPLE 1 - FULL THRUST TAKEOFF
Actual data : OAT = 5 °C
QNH = 1 040 hPa
Engine anti ice ON
Air conditioning OFF
Weight read in the takeoff chart : 75 000 kg
Determine the actual airport pressure altitude (1 hPa is equivalent to 28 ft according to the ISA
model).
Pressure altitude = 4 200 - (1 040 - 1 013) × 28 = 3 444 ft
Read in the above table the corrections for high QNH and engine anti ice ON.
QNH correction = -30 kg × (4 000/3 444)/28 = - 600 kg
Engine anti ice correction : - 300 kg
The maximum permissible takeoff weight is 75 000 - 600 - 300 = 74 100 kg
EXAMPLE 2 - FLEXIBLE THRUST TAKEOFF
Actual data : OAT = 5 °C
QNH = 1 040 hPa
Anti ice OFF
Air conditioning ON
TOW = 70 000 kg
Flexible temperature read in the takeoff chart : TFLEX = 55 °C.
Read TREF on the takeoff chart or on the quick reference table.
Determine the actual airport pressure altitude (1 hPa is equivalent to 28 ft according to the ISA
model).
Pressure altitude = 450 - (1 040 - 1 013) × 28 = - 306 ft
Read in the above table the correction for QNH and air conditioning ON :
QNH correction = 1 °C/5 hPa × (4 000/3 444) /28 = -4 °C
Air conditioning ON correction : -6 °C
New flexible temperature = 55 - 4 - 6 = 45 °C
Check that the flexible temperature is above TREF and actual OAT.
Check that he flexible temperature is less than the maximum flexible temperature and retain the
lower of the two.

Read in the above table the corrections for high QNH and engine anti ice ON.
QNH correction = none
Engine anti ice correction : - 300 kg
The maximum permissible takeoff weight is 73 000 + 0 - 300 = 72 700 kg
