Malaysian Take Offs

I have noticed that when any Malaysian B747 takes off it seems to fly itself off the ground rather than rotate with the tail going close to the ground. I watch them regular at Manchester on take off and every time they just seem to glide off the ground. Is there any reason for this, perhaps different company guidelines on speeds etc.....

Can anyone help??

Best Regards

Steve.

I haven't really paid any attention, or I've left before the MH departs, but I'd guess that the pilots may rotate more slowly than on other aircraft.

Interesting you should mention this, I watched 9M-MPL depart from runway 34L here in Sydney a little while back, and it departed in a very flat attitude as seen here. The subsequent Qantas departure was slightly more 'normal' as seen here.

Cheers.

Wow, I've never really noticed it till now, what is the take off pitch? Is it 10 degrees or 15 degrees?

Nice observation Smile

I might have an explanation, but it can more then one reason. Big grin

For all commerical jets it is nesecary to achieve a screen height of 35ft at the end of the rwy. The Malaysian might be heavy, and the weather might be hot.
It therefore could choose a higher flap setting. it would rotate earlier, but climb out flatter. If there are no obstacles in the vicinity there would be no problem.

In a nutshell it comes down to this: Less flap setting: longer roll, steeper climb-out path.
More flaps: shorter ground roll, but a more flat climb out path.

This might explain it.

Gerbert,

The 747-400 is only certified for Flap 10 or Flap 20 departures. The Qantas aircraft in the photo I linked above is conducting a Flap 20 departure, as do all Qantas -400s. Doesn't quite work unfortunately!

Thanks for the replys, I have mentioned it a few times at the airport but people say I am imagining it, I'm glad I'm not going mad, well, not yet anyway.

Cheers,

Steve.
