No announcement yet.
Why are all Singapore Airlines 777-200ER but some with derated engines?

SQ have never had any 777-200s that were not built as 777-200ERs. All SQ 777-200s are consider by Boeing to be 777-200ERs.

If you mean 777-200s, then you're mistaken, there are substantial structural differences. If 777s that Boeing built as 777-200s cannot be upgraded to 777-200ERs. SQ had Boeing build 777-200ERs for them and then bought them as 777-200s so that they can be uprated later (for more money).

Can't say for sure there. Their fuel capacity is the same, so I think the MTOW of the a/cs would be the same between the 772 and 772ER.

Ah i didnt know that. One question thats going slightly off topic. Can a pilot who pilots the 777 pilot all 3 types SQ have. Do they have a generic type rating. Can a 777 pilot operate the 777-200, 777-200ER, 777-300 & 777-300ER? Or because some have different engines does this not make it possible?
Thanks very much

The 773 and 773ERs are completely different with different engines( for SQ) and some major structural differences. Moreover, 773ER wasn't available when SQ got their 773s.
Thanks very much

Originally posted by mr_botak View PostI think they also reduced MTOW which can equal lower landing fees. The inspection and maintenance intervals will also likely be longer on the "derated" Trents.

What gain do they get by derating them appose to leaving them as standard ER?
Why didn't they do this with the 777-300's?
