Flying outside the box
When I first started flying jet transport aircraft it was in a very unusual environment, namely the Berlin air corridors. We flew the aircraft at Vmo at low level often being pursued by the much faster PanAm 727s. We learned to fly the aircraft at its maximum speed envelope and the arrival at TGL often involved a truncated visual that would be called in this modern age unstable. We did this fairly frequently so we were actually quite practiced at it and able to manage the energy of the aircraft effectively and safely.
With the modern trend to operate an aircraft conservatively and in a narrow speed band is there any justification to teaching a line pilot what his aircraft is really capable of?
