I am just curious as to why continental's a/c reg has just N and 5 digits, as opposed to N###CO or N###CA for ex.

I guess they just don't waste the effort on it. Sort of like most people don't go for the vanity license plates on their cars.


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

It makes it easier to assign ship numbers as well as tail numbers. CO has the last three numbers of the tail number stand for the ship number. For example:

N77014 = Ship 014
N18658 = Ship 658
N83870 = Ship 870

Hope this helps!

Aren't some of the older AA models like this as well . The A306 fleet springs to mind. Maybe CO just couldn't be bothered to change the number pattern and kept it the same to make it easier for us spotters  optimist

That is correct. O and I cannot be used in n numbers to avoid confusion with 0 and 1.

Simply style and tradition.......as pointed out, the last digits of CO's registrations are the tail numbers which is convenient.

Side note: years ago, when CO was intergrating the ex PE/Frontier One, NY Air, fleet into its operations, and in the past when CO has purchased second hand aircraft, it took them "forever" to change aircraft registration numbers........a few of the MD80s flew with their NY Air registration until their retirement I think. Anyone know why?

It costs money to change the Registration, and there was none to spare.

The cost is supposedly minimal to change registration in the USA. I am sure it was more of a maintainence issue, rather than a financial one. However, that would depends on the number of airvcraft to re-register. Take for instance Delta. When they integrated the Western fleet, all of Westerns' aircraft kept their "W" designation.

Up here in Canada, with the merger of Pacific Western and CP Air/Canadian Pacific into Canadi>n, and then eventually Canadi>n into Air Canada, the registrations (all alphabetical) all stayed with the original aircraft. In some instances, you can still find remnants of the original owners:

C-GPW# (Pacific Western)
C-FCP# (CP Air / Canadian Pacific)
C-FCA# (Canadi>n) ...as a review the ">" took the place of the "a" in the english spelling, and the "e" in the french spelling.

Max Q is correct. The cost the FAA charges is based on the type and gross weight of the aircraft, the heavier it is, the more it costs. In the case of used airplanes, if it is registered, almost anywhere, it can still fly in the US. So, this is an added cost. AA did not re-register any of the former TWA aircraft

I was told by the captain on my IAH-LAX flight on Jan. 3 that it had something to do with most of the aircraft having been leased. Is there any truth to that, as well??

Yes, isn't that the reason why Southwest hasn't re-registrated some of its second hand planes, while they re-registrated other planes which came in a the same time, because some owners didn't want the aircraft to be re-registrated?



Its all about supply and demand...

I knew about not being able to use I and O, but was not sure of the nomenclature. The tail number scheme makes sense.

The cost is minimal.....and CO paid the fee to reserve the new 5 digit registration number for each of the subject aircraft, but never followed through to actually re-register the airplanes. Very odd indeed.

There is a sequence to their registrations.

The first two numbers are random, the third digit dictates what type it is and then the last two are the sequence within that type.

Eg.

Nxx0xx 001-049 are 772ERS, 050-099 are 764ERs
Nxx1xx 101-149 are 757s, 150-199 are 762ERs
Nxx2xx are 738s
Nxx3xx are 733s
Nxx4xx are 739s
Nxx5xx are 738s (on order)
Nxx6xx are 735s
Nxx7xx are 737s
Nxx8xx are 753s (were MD80s)

First, there is no FAA regulation that says there must be letters at the end of registration. Continental chooses to use just numbers as RobK says below..

Quoting RobK (Reply 15):

The same holds true with ExpressJet planes. Give just the tail number to an employee of CO and they could tell you what type of plane it is... and what sequance it is in that group of planes. They use this for several things: Maintenance planning, tracking, scheduling just to name a few........

I remember flying on N938AS with CO back in 2000. CO began flying that ship in 1996 and I don't believe they ever reregistered it. It's funny that CO flew that Mad Dog for several years still with an Alaska reg but they didn't waste any time reregistering the 753's they took from TZ.

As it were, in case anybody wondered, the 737-500 didn't received the 500 seris ship numbers because we had DC-9-30's at the time when we got that "terrific deal" from Boeing to acquire the 735 and the DC-9-30's had the 500 seris numbers. Same for the 738 as we had MD-80's, which had 800 numbered ships,but as mentioned above the 800 numbers went to the 757-300. Incidently, the 737 was originally the 737-100 in CAL's fleet but now is the 73G or 737-700. Not sure why the 739 didn't get 900 seris numbers for simplicity as we don't and didn't have any fleet types using the 900 seris numbers. Cont. Express uses the 900 numbers for a handfull of the EMB-145 but they have nothing to do with CAL in this regard,

This is true for most US airlines that use letters at the end, and for many foreign airlines as well. Everyone has patterns, you don't need to stick to numbers for that.

NWA's DC9's (when will they be retired, anyway? and what will they be replaced with?) are fantastic in this respect... still some NxxxNC and NxxxRW flying or parked while still wearing those numbers, and NxxxxE, NxxxxT, Nxxxx, NxxxN, etc.

Aircraft type or weight has nothing to do with the cost of registering an airplane with the FAA. The registration cost is only $10.00 and has been for over 20 years.

The other costs involved are actually changing the number on the airplane either by painting or the use of decals. Logbooks do not have to be replaced, all that is required is a logbook entry stating that on this date the number has been changed to N______.

Leased aircraft will probably require all the aircraft lease paperwork be changed for the lease to remain legal and I would guess that it is not worth the effort.
