‐ Airport elevation : 1 500 ft
‐ Normal air conditioning
STEPS
1:FillinMaxTOweight→200000kg
2 : Enter the integrated cruise table corresponding to chosen FL with TO weight at brake
release point and calculate weight overhead destination (See CALCULATION TABLE)
Fillin→152750kg
3 : Apply temperature correction for given air distance
4 380 nm × 10 °C × 0.010 kg/°C/NM = 438 kg
4:Correctionforairconditioning→here=0
5 : Subtract climb correction for chosen FL (Refer to PER-FPL-FLP-ICR-70 STEP CLIMB
CORRECTION)→2600kg
6 : Add TO altitude correction 0.9 × 200 × 1.5 = 270 kg
7 : Subtract value for step climb correction (Refer to PER-FPL-FLP-ICR-70 STEP CLIMB
CORRECTION) 2 × 160 = 320 kg
8:Calculatecorrectedweightoverheaddestination→149500kg
9 : Enter weight overhead destination and find descent correction (including 6 min IFR)
(Refer to PER-FPL-FLP-ICR-80 GENERAL)→400kg
10:Calculatelandingweightatdestination→149900kg
11 : Alternate fuel e.g. 250 nm at FL 270
(Refer to PER-FPL-FLP-ALN-30 ALTERNATE PLANNING - ISA)→4021kg
Landing weight at alternate 149 900 - 4 021 = 145 879 kg
Correction due to deviation from reference landing weight at alternate (Refer to
PER-FPL-FLP-ALN-30 ALTERNATE PLANNING - ISA) (145.9 – 140) × 11 = 65 kg
Corrected alternate fuel 4 021 + 65 = 4 086 kg
12:Calculatealternatelandingweight→145800kg
13 : Subtract holding fuel : (Refer to PER-FPL-GEN-MFR MINIMUM RECOMMENDED
FUEL REQUIREMENTS)→2800kg
14:Calculateweightatendofholding→143000kg
15:Calculatetripfuel→50100kg
16:Subtract“enroute”reserve(standardamountis5%oftripfuel→2505kg)
17:Calculatezerofuelweight→140500kg
18-19: Subtract dry operating weight to obtain maximum allowable payload
20-22: Calculate block fuel
