757-300 Info Required

[Localiser Green]

I wonder if any 757-300 drivers / tech folk could fill me in on the following:

- Vr Speed range (i.e. lowest weight Flap 15 Vr to MTOW Flap 5 Vr)
- Vref Speed range (from lowest weight to MLW, Flap 30)
- Service Ceiling

Thanks in advance

Flaps,

The basic (APS) weight of a 757-300 is likely to be about 65,000kgs and the max take off weight about 120,000kgs depending on operator. Are your figures for the 737?

Huge apologies..................mis-read the topic!

They are for the 737.

Please ignore everything after Good Morning!!!!!!!!!!!!!!!!!!

Thanks for the 737 info, anyone have it for the 753?

Afraid I dont have the 753 RTOM tables at home, I'll try to have a look next time i'm at work.

Service ceiling is 42000 - as 752, but dont expect to get there with pax on board. If you are doing canaries / greece from the UK, expect to start at FL330.

Off the top of my head typical Vref30 (with4 or 5 tons of gas still on and av. pax load youll have around 140 - 142 kts.
