It is
NOT possible as there are too many variations in aircraft performance with the variety of aircraft types.
Aircraft performance is based on too many factors for an authority to be aware of in regards of all operational types into/out of airports.
A minimum selected performance may be too restrictive for many modern airliners, whereas could become marginally capable for some older types.
Equally this capability is weight dependent, as many aircraft can operate at a huge range of weights with a large variety of engine settings.
It would add too much complexity to be authority based, hence the onus is with the operator, flying only a small subset of aircraft available, who know their type of configuration and performance capabilities.
Some airports do have imposed turn requirements, but these are local and must then be implemented by the airline before operating into the field.
