SQ B777 Registration Confusion!

Following the deliveries of aircraft worldwide I found out that SIA's B777-200 are registered 9V-SQ-(A,B,C...), 9V-SR-(A, B, C...) and 9V-SV-(A, B, C...).
I know the aircraft belonging to each registration group are configured differently (two class vs three class), but I'm wondering why SQ is doing that?
9V-SQA down to SQZ would also work, though it wouldn't be as interesting.

Any ideas?

Udo

The SQs are completely non ER, the SRs have the same engines as the SVs but no extra Fuel tanks. The SVs are full ER. SQA-SQZ would be confusing because they are different types of 777s.

Hello,

Singapore Airlines's 9V-SQ registered B777s series are not the full ER versions. These B777s are the basic versions which have the range for only 5150nm but their oxgen systems are of the B777-200ER types. The engines they are fitted with (RR trent 884) which are only used on the normal non ER B777s and they do not have the additional fuel tanks hence the 5150nm range.

Singapore Airlines's 9V-SR series registered B777s are the IGW version, they have the uprated engines (RR Trent 892, which is used on the ER version) but they do not have the additional fuel tanks so they cannot fly the range the ERs can.

Singapore Airlines's 9V-SV series registered B777s are the real qualified ER version of the B777s, having everything a B777-200ER should have.

I hope this is not too confusing.

Thanks for the info, but I don't agree on the non-ERs. All B777-200 of SIA are listed as ERs in the latest jp airline fleets issue.

Any comments?

Udo,

SQ and SR series are IGW versions. They are labelled as ER versions in the JP Fleets Issue as the IGW is commonlly called the ER.

The SQ has the Trent 884. Similiaries with the ER include its slightly uprated engines, together with the chemical oxygen system.

The SR has the Trent 892, with the chemical oxygen system, also a 2 class arrangement.

The SV has Trent 892, 2 class, and extra fuel tanks and chemical oxygen for diversions over the Himalays (sp).

When I flew SQ224 (PER-SIN) on the J/S, the captain told me about the differences between the 777s in SQ's fleet. Basically the main difference would be in the fuel capacity as well as the engines.

Hope this helps.

-Regards, Tsentsan

I find this very strange too but I was told by a senior SIA first officer when I flew on a SQ B777-312 in Sept during a cockpit visit.
