Takeoff performance - wrong wind

Recommended Posts

Hi,

 

When I calculate takeoff performance for my OFP PFPX always uses 330/20 as the wind of the departure airport. For the landing performance it is ok. As I am able to manually override the value with the correct wind before calculating, I have a workaround. But it would be nice to fix this with the next version.

You have planned the flight for the 5th at 1800Z:

DOF/190105

 

The TAF forecast for that time:

 

TEMPO 0516/0603 33020G30KT 9999 SHRA FEW010 BKN020

 

330@20kt looks correct ?

Ohhh - thanks. That explains this behaviour. I planned the flight for the CPT at LGTS today.

Many thanks for clarifying this mystery.
