The 777-300er seems to be a lot less powerful since the update. It struggles to climb and maintain 34k. Once it’s there it usually starts bobbing up and down trying to gain stability. This is with the weight only at 66%. Definitely didn’t have this issue before and none of the other 777s have that problem.
You have to decrease the VS the higher you climb as the air density gets lower, so not as much lift is generated, and the engines are less efficient. Try trimming it.
I definitely decrease it as I go higher… Even decreased the VS to +200 to really ease up to the cruising altitude. And still the same problem.
Cruise lower then, 77Ws are well know for them not being able to achieve high altitudes early in flight. FL 310 or 320 will probably be more suitable. If that doesn’t work, FL280 is always an option.
The 777 used to be a solid airplane before the update. I don’t fly it as often as before anymore…due to these new issue. The 747-8 is just perfect for me. Just load it up and fly it like the boss.
Indeed it was. It sure lost a LOT of power and is now somewhere between the C17’s current model and the A330 in flight characteristics.
Just tested it, no idea what you guys are going on about. It flies perfectly.
It’s all about when you decrease. By 10,000MSL you should only be climbing at +2500fpm at most, by FL200 you should only be climbing +2000fpm. After passing 10,000MSL you should accelarate the aircraft to at least 320AS. Once you reach an altitude where the GS shows up instead of AS you should only be at M0.84 in the 777 as that’s it’s typical cruising speed in real life.
What speed are you at?
Same here. I think this is pilot error. Not enough to be sure though.
I’m not so sure about that.
It seems like all of the updated 777’s were massively derated.
Or are the old 777s massively overrated? 🤔
It could actually be a little bit of both.
There was simply too much lift on the old 77Ws, the new ones reflect the correct flight characteristics.
I wouldn’t exactly say that they have too much lift.
What, the old ones? Definitely, the old ones are quite inaccurate at altitude. I have a logbook entry on a 77W, the weights and cruising altitudes now line up. It works.
Its definitely much less powerful since the update and the nose pitches up so high at cruising altitude. So disappointed with this 777W rework. Funny how a staff member cites pilot error as the reason…sometimes it’s better to put pride aside in order to really ascertain the truth.
How high? Like 3 degrees? That’s quite normal, you just don’t notice it on the plane.
It’s was at 5 degrees with -25% trim.
You know that trim doesn’t affect deck angle right?
