degrees
if nothing else it uses precious radio time. "turn right heading zero two zero" is all you need. do you turn to a flight level? to a speed? what else are you gonna turn to? the extra word 'degrees' is not necessary. if they say reduce to two one zero, does that mean descend to FL 210??? reduce heading to 210 degres? where exactly is the confusion?
