737NG performance calculation
Hi fellow aviators
Please I'm stuck trying to compute the V speeds on the performance dispatch section as it's been years ago since I last did it.After I have interpolated the speed for the Flap setting I require I don't know how to do the V1,VR,V2 adjustments and the VMCG I'd appreciate if someone refresh me on those. |

I think there's way to many variations on how the data is displayed for anyone other than a co-worker to comment on. Without seeing what you're working with, we we can't be of much help.

Use FPPM charted information, if you still have one...

Hi Imbracablecrunck
Here are the data: Gross weight:57000 KGS Temperature: 13 degrees Slope:0% Dry Runway,Flaps5 24K Airfield elevation:7650 Feet My issues come from the V1,VR,V2 adjustments I appreciate your help |

Pressure Altitude: assumed 7650 as not provided
Takeoff Speeds - Dry Runway (24K Derate) - FLAPS 5 WEIGHT (1000 KG) : V1/V2/Vr 60: 131/132/142 55: 124/125/136 Interpolated figures for 57: 127/128/139 Pressure altitude corrections: +4/+4/-2 -> 131/132/137 Slope correction: none Wind correction: assumed none as not provided Clearway and Stopway corrections: assumed none as not provided V1(mcg) for pressure altitude: 89 |
Thanks Skyjob
It looks very clear to me now.I really appreciate |
