Qantas 747 -OEB QF 93/94

[Anthony F]

how does Qantas run OEB to LAX and back as it is not an ER aircraft? i thought only ER aircraft were used due to the extra fuel and distance required non-stop. I assume this aircraft would not be full leaving LAX to MEL.

Most likely the flight would be quite severely weight limited, unless there are some particularly good winds travelling west at the moment. Noticed that VH-OJF departed a short time ago from LA as the QF94, with an ER VH-OEJ operating QF108. Maybe they just don't have the demand on the Melbourne flight.

Before the ER's arrived OEB, C and D were used almost exclusively to LAX. Their GE engines giving better performance than the RR aircraft.

OEB,C,D, OJT,S,U were the SYD-JNB and MEL/SYD-LAX. The GE's offer more range essentially, and S,T,U had upgraded special engines that are more fuel efficient than the rest of the fleet.

[Todd Hendry]

Brenden,
Not sure about S,T,U having more efficient engines.
Pretty sure all the RR's are the same.
Todd.

[Fred C]

Tis true Todd there is nothing special about the engines on S T & U.:D

[Jason H]

Would they not be slightly more efficient due to their age?

[Rowan McKeever]

Not if one of the older aircraft had new engines put on in an overhaul?

[Tom PER]

Didn't OJS to OJU have RR Trent components in the engine such as the core and at the time the exsisting B744 fleet OJA-OJR didn't have this, but have since been upgraded to the same spec??

The GE engines seem a hell of a lot more reliable also.

The original batch of 744s (OJA-OJR) were delivered with the basic RB211-524G spec, whilst the later frames OJS-OJU were RB211-524G/T spec. The remainder of RR 744 fleet were upgraded to that spec between 2003 and 2005.
