Re: Question: 747-8 to Freighter easy conversion possible?

The 747-8I has the fwd fuselage plug (160 inch) installed aft of the upper deck door, so the upperdek floor will be removed just aft of the upperdek doors by a P2F conversion, so conseg. the 747-8 extra stretch has no effect on the number of 8 ft (limited) fwd maindeck pallet positions, compared to...

Re: Question: 747-8 to Freighter easy conversion possible?

This is interesting. However, I don't see the business case for this, as there is no nose door (and that is the reason most airlines utilize the 747-8F or 747-400F factory). Though, it explicitly said "CAN BE CONVERTED TO FULL FREIGHTER AFTER DOOR INSTALLATION" and the hours are low. Time...

Re: Question: 747-8 to Freighter easy conversion possible?

Boeing said the 767 was a better airframe for military programs. You can't just cut holes in a CFRP fuselage to mount antennas and other military systems on the outside of the fuselage the way one can with aluminum. The A350 side panels are made without door and window openings etc, and they cut th...

Re: Question: 747-8 to Freighter easy conversion possible?

A 748BCF would still have more volume than a 744BCF despite the longer upper deck. And the 747-8i has a MTOW ~50t higher than the 744 (I don’t believe any of QF’s 744ERs were ever converted) so I wouldn’t expect the increased fuselage mass to have much more of a hit on cargo than the 744BCF.

That's correct, but almost all (modified) calculations can be based upon the 744BCF STC and have only to be checked by the FAA, the only new to be "life"demonstated system is the maindeck fire/smoke detection system, only when the SUD will be retained and more tension ties are installed. ...
