ATPL Perf. APLA Calculate Air dist Y-TOD for B727 pg 3-2
Hi all, can someone please confirm they way the calculation is done for the following from page 3- 2 of the CASA B727 Performance and Operating Handbook.
In example 2 it states:
Given:
TOD GW: 62750 kg
Flight Level: FL290
Temp: ISA
Cruise Schedule .82 M
Wind component: -40 kt
Segments: Y-TOD: 204 nam
X-Y: 342 nam
Enter Table FL290/.82M curis ISA with GW 62750 kg
Extract Cruise distance from Wt of 62800 kg: 870 nam
Calculate Air distance Y-TOD - Add : +222 nam
= 1092 nam
How are they getting the +222 nam?
It is possible you could show working ta.
