As a Level 1 Instructor, what action would you be likely to take if you observe a gross breach of airmanship and/or flying discipline on the part of a solo pilot, if the Level 2 Instructor on duty was in the air at the time?
Firstly, let the pilot know that you saw what had occurred and you had some concerns about it. Remembering that you are not in charge of the day's operations, you may at your discretion invite the pilot to give you his/her side of the story. It might be that the occurrence had a perfectly feasible explanation. If not, and you are concerned that the pilot should not fly until further counselling has taken place, advise the pilot that you wish to consult with the duty Level 2 instructor and to remain on the ground until you have done so
