Fully Laden 747

Fri Nov 07, 2003 2:10 pm

I always wondered what would happen if a passenger and fuel fully laden in Mexico City 747-400 taking off on RWY 5R or 5L had to abort takeoff at V1? Any ideas?

if the runway were too short for aborting at v1 the pilot (if he survived) would likely have his license withdrawn for attempting to take off beyond MTOW for the airport.

Since V1 is based on the airplane and airport conditions, probably nothing more then a few tires (tyres) going flat.

Dear Ar385...

Many airplanes are severely restricted at MEX because of elevation and the temperature. I do not have the figures for the 400, but for a typical 200/300, your maximum takeoff weight would be reduced to some 350,000 kg, while these airplanes are certificated to takeoff at 377,800 at sea level...

As to making a V1 abort (even taking off at 350,000 kg)... I would say it is definitely not a good idea. Generally, I consider that we are commited for the takeoff as early as V1 - 5 or 10 knots... after that, I would continue...

What I say is not "me"... It is a Boeing official recommendation...

So you are saying the MEX operation of a 747-400 is marginal?
