Min speeds
 

Could you fine people provide me with the min speeds for the following aircraft, both mach and ias, for the levels fl380 - fl200?

B747, B777, B767, B737, A380, A340, A330, A320, A319

It's for a briefing I'm doing at work so that we can more accurately and safely work traffic during periods of large delays into the ltma. Our new kit works better if we have accurate speed info to enter into it rather than just "min speed". I'd rather know it than have to ask. The types I've chosen are the more common types that we work.

Thanks

Hard to answer as the minimum speed depends apron the a/c weight and FL and can vary up to 25 kts.

An A330-300 at around max landing weight at FL200 Min speed is about 220 KIAS ( Mach .5 ) and at FL 380 about 245 KIAS ( Mach .77 ) This is based on Green dot plus about 5 kts for mum dad and the kids!!

As previous poster stated. Very hard to say.

B757 and B767 in our company, and I suspect other Boeing types.

Above FL 200 Minimum Airspeed is Vref 30 + 80 knots or 'top of the amber display' on the ADI speed tape, which ever is greater on aircraft so equiped
or those aircraft not having a speed tape, Vref 30+100 knots.

Vref 30 is the reference speed for Flaps 30 (max flap) and as such varies greatly with weight.

If you wish further info I would suggest approaching a few of the airlines.
