Maybe as it's the thirty year anniversary of this tragedy it might be a good time to remind some people out there of one of the recommendations made following the accident..that in order to avoid confusion regarding clearances the term "take-off" should only be used in the first instance by the tower and only when issuing a take-off clearence.... yet still on a daily basis I hear crews informing the tower that they are "ready for take-off"... the correct term in case your PPL instructors never got the message is "Ready for Departure " ...or, if that's too much to remember... just call "Ready".... let's at least try to avoid another Tenerife.
