757-300 Info Required
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 ;) |
The weights available will vary with different operators and the many and varied different specs and certification. The following come from my Boeing QRH.
VR Flap 1 35 Tonnes 109 65 Tonnes 163 Flap 5 35 Tonnes 104 65 Tonnes 156 Flap 15 35 Tonnes 100 65 Tonnes 147 Vref Flap 30 35 Tonnes 111 52 Tonnes 135 Ceiling is 37000 feet. |
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. |
Here we go:
Flap5 125 tonnes Vr182 110 tonnes Vr169 95 tonnes Vr155 80 tonnes Vr139 70 tonnes Vr127 Flap15 125 tonnes Vr170 110 tonnes Vr158 95 tonnes Vr144 80 tonnes Vr130 70 tonnes Vr119 Flap20 125 tonnes Vr158 110 tonees Vr146 95 tonnes Vr134 80 tonnes Vr120 70 tonnes Vr110 For LND Flap30: 101 tonnes Vref143 90 tonnes Vref134 80 tonnes Vref 126 70 tonnes Vref118 Best regards |
Yeh those figures look about right to me.
