BA 744...registrations?

Sun Feb 08, 2004 10:23 pm

On BA's 744's they have two types of reg, some start with G-CIV and others
G-BNL.
Anyone know why this is?

Simple G-BNLA-BNLZ are the first batch and are standard CAA in alphabetical sequence allocations.
G-CIVA- onwards are out of sequency special allocation NOTE The CIV bit can be read as roman numerals!(Work it out !)
G-BYGA are back to in sequence allocation but they are actually the newest aircraft
Answer your question ? (CIV = 400 !)

I'm BA crew, and I'm fairly sure the G-CIV+ aircraft are subtley different.

I think they have a different IFE system than older -400s. I'm not a CSD, so I can't be 100% sure - and I hardly ever operate the jumbo anymore.

Good point thats the complexity of Roman Numerals you see but it is also 100 4 times !

104 would i think be ivc
thats 5 minus 1 plus 100 = 104

CIV is indeed 104 ( C=100, CI=101, etc....)
CD = 400

As far as I know, and I'm no expert, IVC is not a valid way of writing 104. In fact, IVC is not a valid notation for any number. There's a rule I think for not subtracting I from a number that is 10 times greater. So you can write IX for 9, but 19 for example, would be XIX (not IXX).

Your absolutely right about the rule and it would be correct to write CD that's 500-100.
and civ which is 100 +5-1 for 104 BUT BA really DID choose those combinations to represent 400 thats hundred four times !
Anyways this is getting esoteric and not really anything to do with aircraft Thanks AASilverbird.
In the UK we have a habit of using mis-interpretations of letter combinations to represent differing words within car registerations that has passed into the aviation world.
In the case of BA they also use G-EU-- on their airbus aircraft to indicate they are an EU airline but wouldn't put an EU flag on the aircraft for FEAR of being castigated in the right wing British Tabloid Press !

IVC = 96

Well, this is one way of writing it. I learned it differently. So I would write 96 as: XCVI.

I don't know if one is more correct than the other....
