CF6-80C2B1

The cockpit is a modified 200/300 type. Some steam gauges, some glass.



I don't understand everything I don't know about this.

I believe that they still have a flight engineer, and Air Force One still carries a navigator along with a fairly large complement of communications and electronics specialists as well. The cockpit is a mixture of glass and guages, since remember that these planes are realtively young.



Why do Aerospace Engineering students have to turn things in on time?

But they're not going to do that at this point because an RFP is out for a possible replacement.

Good to know. I didn't realize that that was official yet.

How do you know this? Just because an RFP is out for a replacement in the next decade doesn't mean the aircraft won't be upgraded in the meantime....

Yes, and since EADS has said they will they will not offer an A-380-800-VIP, it look like the only offer will come from Boeing offering the B-747-8I-BBJ/VIP.

Actually both VC-25A aircraft are already upgraded with a partial glass cockpit.
The navigation system is fully updated with FMS and GPS and LCD navigation screens.

see this Supplemental Type Certificate (STC) of the 747-2G4B (VC-25A) :

http://www.airweb.faa.gov/Regulatory...A4?OpenDocument&Highlight=747-2g4b

Also the GE CF6-80C2B1 engines, with PMC, a sort of supervisory digital fuel control, are the most powerfull and fuel efficient engines that were offered on the 747-200/300 and are the same as the 747-400, except for the (FADEC) fuelcontrol.
Only seven late production 747-300's were produced with this engines and the two VC-25A's are the only 747-200's powered by these engines.

In fact this aircraft is only 3- 4% less fuel-efficient as the 747-400.

Operating a twin over the ocean, you're always one engine failure from a total emergency.

As we all know the two VC-25As have the GE CF-6-80C2B-1 engines of the B-747-400.

The four C-32As have P&W PW-2040 engines while the two C-32Bs have RR RB-211-535XXs

The C-40B/Cs have the CFM-56-7XX series engines.

A bit off topic. There used to be a multi part documentary about Air Force One on Youtube. Somehow it has disappeared. I wonder whether this is due to an insturuction by the White House. The video did not reveal much but was enjoyable to view every now and then. Pity.

The big reason for a glass MFD cockpit is to reduce the manpower needs in the cockpit.

Those devices are not substantially more accurate than some of the older technology - the main advantage is that they save the airlines having to pay extra crew members.

As noted above - the VC-25 flies with a full-time flight engineer and a full-time navigator. That reduces the work load of the pilots more than a full glass MFD cockpit. The pilots are also only responsible for direct communications with ATC. All the other communciations with ACARS, the airline ops center, dispatchers, etc - is handled by the communications specialists on board.

If they were to get into an situation like many airline crews where they needed to communicate with the HQ maintenance staff about troubleshooting an issue on the aircraft - on the VC-25 the pilots would not have to devote their attention to that problem - the flight engineer would be doing that job.

Thanks, I couldn't have explained it better.

Was that from the National Geographic (NatGeo) TV show from a few years back? If so, I would suspect it was more due to copyright infringement complaints from NatGeo rather than from the White House.

I don't the particulars of this case, but the White House is, and has been thru many administrations, fanatical regarding the proper use of it's "trademarks" - Presidential Seal, Air Force One, etc. Witness the recent debacle regarding the pix of Obama and his jacket.

To my knowledge there are only "straight" C-32s, and all of them have PW engines. But correct me if I'm wrong.



Exceptions confirm the rule.
