Thu Feb 07, 2019 2:55 am

Can anyone tell me the difference between NW/DL’s 744s and UA’s 744s?

744 built for NW were identified as 747-451; UA’s were 747-422.

Some had Northwest painted on the side and others had United painted on the side.

United actually took 2-3 Northwest 747's that were not taken up.

Do not forget that UA took two 400’s that NW stiffed Boeing on after they were built and outfitted

Northwest's ended up wearing the Delta scheme. United's wound up in Continental colors.

Didn’t UA’s 744s could be able to fly routes like ORD-HKG and JFK-HKG while the NW 744s can’t? I mean when NW flew MSP-HKG they had to weight-restrict the aircraft.

One thing that they have in common is that they're all parked. Too bad, UA or DL didn't find a compelling business case for 747-8s.

Since the UA pilots on the 747 referred to themselves as "four hundred" pilots (an apparent reference to the days when UA had both 747-200s and 747-400s), if UA had ordered 747-8s, would they have called themselves "dash eight" pilots?

NW operated with a higher density, two-cabin configuration that UA’s three cabin. Plus, it wasn’t the weight restriction that doomed MSP-HKG...

The NW 747-451's had an extra selection on the Glare shield for INS3 that United's -422 didn't have, And the sidewall Pan-Lam was a little different in the cabin.

Ooooooooo, that paint looks super heavy. Maybe that's what led to the weight restrictions.

When Boeing designates a 744 aircraft as “-451” or “-422” what does it mean? I believe Boeing also uses similar designations for other aircraft. Does Airbus use a similar naming convention?

While Boeing doesn’t do it anymore (hence why it's now 747-8 and not -800)is they used to use the last 2 places for customer/configuration codes. For example a 737-222, 757-322, and 747-422 would all be planes built for United as their customer code is (was) 22.

To answer a potential follow up question, the code stays with the plane even if sold to another Boeing customer that has a different code.

This along with that they don’t do custom configs for airlines (aside from plugging/unplugging an emergency exit for high dense configs) is why they stopped doing it.

However I still prefer -800 to -8

Here's a list of Boeing customer codes: https://en.m.wikipedia.org/wiki/List_of ... t_sequence
C402 9K | B1900D US | ATR72 AA | DHC8 US | CRJ2 US | E175 UA | E190 B6 | D93 US | M88 US/AA | 732 US | 733 US/WN | 734 US | 73G WN | B738 FJ/QF | B752 US/AA | B762 DL | B772 UA | B77W EK | F28 US | F100 US | A319 US | A320 B6 | A332 FJ | A380 EK

You're kidding, right?

Simple answer: one is built by Airbus, the other by Boeing... :roll:

I'd guess that KICT's combined seniority (actually longevity) figure is too low. But that's just base on my personal observations and not a scientific number.

Northwest and Delta's Boeing 747-400s are all one and the same, just a different paint job on the plane.

OK, so were there any actual configuration differences between the -422 and the -451? They were the same model with the PW engine offering, but were there any other customer-specific differences?

Yes, really. We all know this is the real question. While quite specific it's interesting from an avgeek prospective to learn the differences between very similar aircraft.

Some customers opted for the HST (Tail tank), while others did not. -400F freighters did not have this option. As for DL or UA, I don't know.

Only obvious one I can tell so far from looking at pictures is Northwest used the single-cue flight director, whereas United uses the split-axis flight director.
