|Quoting Max Q (Thread starter):|
What, if anything is done with this tank on the Pax to freight conversions, is it retained in service, locked out or even completely removed ?
The Boeing passenger-2-freighter conversion kit for the 744 requires the tank in the HST
to be locked out. The fuel tank remains in place. The deactivation of the tail tank reduces a freighter's fuel capacity by around 12 500 litres.
There is also a Bedek conversion option in the land of Palestine which is slightly cheaper than the Boeing conversion. I believe the FAA/EASA issued a separate STC for it. I'm not sure if they retain or remove the tank.
