B767 Performance
This seems a stupid question, but hey... gotta ask.

A person has said to me that a B767 would shake itself apart at over 220 mph (not kts) at 1000 feet (AMSL / AGL). I say it's bull, but can't find something I can point to, to actually conform that.

Can anyone help with a reputable website that refutes such a claim?

Cheers!

Convert MPH to KTS, then think about V2+10 speeds at heavy weights, i think that you will find that no commercial airliner will "shake itself apart" at such slow speeds!!!

Methinks your friend doesnt know what he is talking about!

The max speed for a 767 below 8000 is 313 knots ( about 360 mph) if it is CAA registered and the highest V2 I have seen was 177 kts giving a target initial climb speed ( V2 to V2 + 15) of up to 192 kts or 220mph so your friend is talking b*****ks. Flap 1 limit speed is 250 knots.

Thats just the limitation on the windscreen for birdstrike protection.

The aircraft is perfectly capable of achieving its VMO of 360Kts at low level.

I agree with the above comments, but are there any online references for Vmo / Vne below 8000?

Thanks again for humouring me.

The restriction below 8000 is purely a British CAA requirement for bird strike protection.
