Yesterday Cathay announced an order for six new B747-400ERFs, to be delivered between May '08 and April '09. These are the last B744Fs to come out of Seattle before Boeing switches the production line to the B744-Advanced aircraft.
The Extended Range Freighter has a maximum payload of 248,600 pounds - 22,000 pounds more than our current 744Fs and a maximum range of 9,200km, 525km farther.
Given its enhanced range and payload, CX plans to deploy these new aircraft on the North American routes, which will mean that, even with a very full load, CX will be able to avoid an eastbound tech stop between HKG and ANC.
The ERF is offered with Pratt & Whitney or GE engines and CX have chosen the PW4062A for compatibility with the existing fleet. The GE engine is perfectly capable but CX would prefer not to introduce a third engine type to the fleet at this time.
Currently CX operates 14 freighter aircraft - one 744BCF, six 744Fs and seven 747Fs. CX have another five 744BCFs on order - two will be delivered later this year and three in '07. In addition CX have retained options for a further six 744BCFs, which are currently scheduled for delivery between the end of 2008 and 2010, though today's order for ERFs may mean a later entry-into-service date for some of these converted aircraft. The timing of these aircraft into service depends, to a great extent, on CX's ability to train the crews quickly enough. Also the delays to the A380 programme may have an impact on the B744 market and the availability of second-hand aircraft.
