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)
Fill􀀃in􀀃→􀀃152􀀃750􀀃kg􀀃
3 : Apply temperature correction for given air distance
4 380 nm × 10 °C × 0.010 kg/°C/NM = 438 kg
4􀀃:􀀃Correction􀀃for􀀃air􀀃conditioning􀀃→􀀃here􀀃=􀀃0􀀃
5 : Subtract climb correction for chosen FL (Refer to PER-FPL-FLP-ICR-70 STEP CLIMB
CORRECTION)􀀃→􀀃2􀀃600􀀃kg􀀃
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

9 : Enter weight overhead destination and find descent correction (including 6 min IFR)
(Refer to PER-FPL-FLP-ICR-80 GENERAL)􀀃→􀀃400􀀃kg􀀃
10􀀃:􀀃Calculate􀀃landing􀀃weight􀀃at􀀃destination􀀃→􀀃149􀀃900􀀃kg􀀃
11 : Alternate fuel e.g. 250 nm at FL 270
(Refer to PER-FPL-FLP-ALN-30 ALTERNATE PLANNING - ISA)􀀃→􀀃4􀀃021􀀃kg􀀃
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
