B777-200LR
 
Right, done a quick search but no hits.
Apart from the obvious fuselage length, what are the physical differences between the B777-200LR and the B777-300ER?
Had a quick shufty through the training notes for the first in service -200LR (transiting through MAN on 25th Feb) but can't see a lot of obvious differences.
I'm not talking about range/payload here just engineering differences.:ok:

Loads of differences, too many to mention but the main ones are:
1. GE90-115B engines, wavy fan blades
2. Longer fuselage 5 pax doors, (longer walkaround!)
3. Tail Skid
4. Boost Actuator on the MLG's, affects the rotation rate at take off
5. Main and nose gear track cameras fitted to Horizontal stab and belly with associated lights.Viewed though an extra synoptic button.
6. Bigger wing fuel tanks
7. Heavier wheels and brakes
8. Some very snazzy Crew rest areas in the upper lobes
9. hmmmmm thats all i can think of, maybe also electronic flight bag but i think that's an option

LME (GOD), I think you have misread my post.

What I'm looking for are the differences between the
-200LR and the -300ER

-300ER has

1. GE90-115B engines, wavy fan blades
2. Longer fuselage 5 pax doors, (longer walkaround!)
3. Tail Skid
4. Boost Actuator on the MLG's, affects the rotation rate at take off
5. Main and nose gear track cameras fitted to Horizontal stab and belly with associated lights.Viewed though an extra synoptic button.
6. Bigger wing fuel tanks
7. Heavier wheels and brakes
8. Some very snazzy Crew rest areas in the upper lobes (only as requested by operator)
9. hmmmmm thats all i can think of, maybe also electronic flight bag but i think that's an option

So the differences are that the -200LR doesn't have a tail skid.

But thanks for trying.:ok:

Hasn't the LR got extra fuel tanks in the cargo bays? Or at least the option of fitting them.

Same engine, just a pin change from 110 to 115 on the 772LR to 773ER, what is the question....

Title - 772LR to 773ER
Post 1 - 772ER to 773ER

772ER is not close to a 772LR
