Maybe i'm getting too old for that already.....
For all those who had the privilege to fly former generation aircraft it is absolutely
clear that flying below GD is stupid. Actually it's more or less a funny Airbus name for
clean speed. I know Airbus proves it to be possible, just as to stall a plane that supposedly
does not allow stall.
In the days with manual throttles we flew 1.5vs as clean speed. As the AT's and their protection modes
took over, this margin was reduced to 1.3vs. However this all applied for cruise and approach. On take-off
there has always been the 1.2vs because thrust (or power) was fixed on CLB or
MCT or equivalent. So comparing flying below GD on climbout (V2 speeds) with below GD in descent/approach (Vcl speeds),
with partial power or idle, shows little airmanship or aerodynamical knowledge. Airbus can give their
speeds any weird names, it all comes down to vs. Because even a Airbus can stall, it's only more or less
well protected against it with its allowed envelope.
There is very little reason to fly too close to min speed, you trade margin and pax comfort (att)
for just a little show off of knowledge of AOM's but lack of airmenship.
