'normal' procedure is a Vy climb to (usually) circuit height
That seems definitely wrong, for several reasons:
- poor engine cooling during Vx (or Vy) flight
- in any high-perf plane, a conflict with arriving crosswind traffic
- a conflict with any traffic arriving on downwind etc joins
- an extended period of poor forward visibility
- a poor stall margin if there is turbulence, wind shear, etc in the departure area (slow flight is usually a bad idea)
After takeoff, one needs to climb at Vx until obstacle clearance is assured (let's skip the "Switzerland" case
) and then trim forward
ASAP to a higher airspeed for good engine cooling and good forward visibility. The engine controls are not touched until cruise level is reached (again, ignoring stuff like higher altitude climbs e.g. above 5000ft). This procedure will generally mean that you are well separated from arriving crosswind traffic, and you have a reasonable chance of spotting crosswind traffic which is grossly incorrectly positioned (which is very common).
