733driver, there already is one standard (ICAO Annex 2, para 3.2.5)
3.2.5 Operation on and in the vicinity of an aerodrome
An aircraft operated on or in the vicinity of an aerodrome shall, whether or not within an aerodrome traffic zone:
a) observe other aerodrome traffic for the purpose of avoiding collision;
b) conform with or avoid the pattern of traffic formed by other aircraft in operation;
c) make all turns to the left, when approaching for a landing and after taking off, unless otherwise instructed;
d) land and take off into the wind unless safety, the runway configuration, or air traffic considerations determine that a different direction is preferable.
I'll let you figure whether this standard is being applied.
