Re: For Pilots: What Is Your Favorite Route/Flight Story?

I was operating a King Air 200 from Herat (Afghanistan) to Peshawar (Pakistan), a 530nm sector for the Red Cross in 1999. A MAF C210 started at the same time as us, also heading for Peshawar. He very kindly suggested we taxi and back track first as we were obviously quicker. We heard him get airborn...

It is possible to upgrade EIS 1 (CRT) to EIS 2 (LCD), Airbus offers an SB for the retrofit. It has been done on all mentioned Airbus A/C, just a matter of willingness to pay the pr...

Not B777 info, but just as an example. An A340-600 on a 16.5hr flight (JNB-JFK for example) will need to dump about 110 000kg of fuel for a turn back. It dumps at 1600kg/min, so about 68min less engine fuel burn. The A340-300 dumps at 1000kg/min, so that can also take a while.
