[QUOTE=rickair7777;970901]For FAA purposes I don't think there is a provision for logging instructor time if the student was in another aircraft. If you ever need to use your IP time to meet FAA instructor requirements (such as 141 leadership positions) that time would be invalid.

If you ever end up apply for a civilian instructor job where they are actually looking for instructor time, they might look at you funny when they find out that a lot of your logged time was not in the same aircraft as the student.

Many airlines actually consider instructor time as second-rate time compared to actual pilot time...for that reason alone I would probably log section-lead instructor time as just flight time. If you were on the stick, take credit for it. Maybe keep a separate column for that sort of IP time.[/QUOTE

Way off on your advice. What did you fly in the service and when did you get hired in the airlines?
