Another Question About Engine Use Of ANZ 747s Please

[Aharon]

Shalom and greetings all my pals,

In reference to my previous posted thread asking question about whether Air New Zealand 747s had metallic engines or not which resulted into confirmation that those planes did have shiny metallic Rolls Royce engines thanks to the linked proof posted by NZFF forum member Deaneb as seen on this hyperlink: viewtopic.php?f=7&t=33487, I have another question about engine use for those planes, please.

As seen below via NZFF forums' screenshot banner that just came up on top of the forums today, I was surprised to see NON-Rolls Royce engines for the planes. Is it correct or not?? If it is correct, then I have to look in Avsim library for the Air New Zealand 747 with NON-Rolls Royce engines.



Thank you for any assistance any of you might provide to answer my question.

Regards,

Aharon

As I mentioned in your other post about the engines...when I did that screen, there was no Rolls Royce option for that model...so you wont find anything on Avsim.
Again referring back to your first engine post , no its not a Posky model....its an X-Plane 12 model, and I cant remember who painted it.

Splitpin,

Ahhh thanks for your answers. I did see your answer in the other post but I thought you were talking about my question on whether Rolls Royce engines were supposed to be metallic shiny or not. I did not realize you were talking about wrong type of engines. Problem solved.

All 5 of the 747-200's had Rolls Royce RB211 D4 engines, and then the first 3 of the 747-400's had Rolls Royce RB211 G3 engines.
The rest of them, which I think from memory was 5 747-400's, were powered by General Electric CF6-80 C2 engines.
The RR D4's were, for want of a better description, mechanical.
The RR G3 and CF6-80's were all FADEC engines.

Great reply..... thanks , filled in a few gaps. Nothing like some professional knowledge

Ex ANZ Eng,

Thank you for extremely specific breakdown on use of engine types for all ANZ 747s and nice to meet you on the NZFF forums.

And the PW JT9 engine was a further technical step down from the RB211 D4. I never operated the JT9 eng. The RB211 G3 and GE engine were relatively similar to operate. However, I do recall having to regularly use standby ignition on the 747-200 due to regular ignitor issues. This was done "automatically" by the flight engineer it there was no light of withing so many seconds of placing the fuel cutoff lever to RUN or RICH.

Most likely won't remember (let alone have been aware) these .... but ....

We/ANZ wet-leased a B747-100 from TOWER AIR for around 4 weeks during early/mid 1989 .... aircraft was N603FF powered by P&W JT9D series engines. It remained on the US register and operated in full TOWER AIR livery for the entire duration of its short-term ANZ lease .... without any hint of an ANZ decal/logo/name anywhere ....
https://scontent.fakl2-1.fna.fbcdn.net/ ... e=6A0A5B4E
This all happened not too long after the UAL B741 cargo door incident near HNL .... after which aircraft age/cycles was being thrashed-around by international media for quite a time afterward. ANZ needed extra temporary lift at the time. TOWER AIR's N603FF is all that was available to it .... albeit much to the airlines embarrassment. It never wanted being associated with such a high-time aircraft as N603FF was (given media coverage of the UAL incident) or the B741 either .... and even went so far as to try'n invoke a media photo ban at AKL where this particular aircraft was concerned. On a lot of occasions in life it's what one knows that can work to one's advantage .... not to mention who one knows too .... so I was able to (covertly) get ETA times and managed photographing this aircraft, at AKL, "twice" (and rather inconspicuously) during it's short-term ANZ lease.

We/ANZ also leased a B742 "for some 6 weeks only" during 1996 too. Aircraft entered the NZ register as "ZK-TGA" .... leased-in from THAI AIRWAYS INTERNATIONAL (HS-TGS powered by GE CF6-50C series engines .... same as those which powered our DC-10-30's).

The above image "is not" one of my own, but, I was called-in by ANZ maintenance at the time to photograph this aircraft at AKL Engineering. Photos were taken just prior it's ANZ service entry .... primarily to satisfy the Japanese Civil Aviation Authority. No civil aircraft (at that time .... dunno if this's still a regulatory requirement) could be operated to Japan (at leased not without incurring a potential penalty) until their CAA division had been supplied with such imagery covering 6 different aspects of any aircraft (full port side elevation, full starboard side elevation, port forward elevation, starboard rear elevations, close-up of NG door registration suffix port side/and close-up of rear fuselage full registration starboard side). In fact the airline was, during this same period, transitioning into its Pacific Wave livery, so, I was additionally requisitioned to photograph each of its B747's (in the then new livery) .... to satisfy the same Japanese CAA regulatory requirements prior each aircraft being able to operate into Japan. ZK-TGA was operated in a plain white livery featuring ANZ titles and tail logo of the period throughout the entire duration of it's short-term lease.

I know when I was testing the engines, the GE engines lit off virtually instantly and was hard to time the "fuel on to light off", but the RR D4's were that slow you just about had time to make a cuppa...lol

[cowpatz]

Yeah, they were slow. From memory if it hadn't lit off after 25 seconds from selecting the Fuel control lever to RUN or RICH then the FE would select the Standby ignition on. That sometimes lead to a lick of flame out the back end. The triple spool arrangement made it heavier than similar engines by something like 400 kg. So, the empty weight of the RR aircraft was heavier than the CF6 GE engined aircraft. It also had stainless piping that was solid but a pain to change (No flex and heavy). A solid engine though, and quite a bit shorter than other engines.
