how do I sign myself as flight instuctor in the flight log?
Thanks for the question!
Do you mean how to log a flight with yourself as flight instructor? Generally, you would log the time in the Flight Instructor duration field (tap + Add Duration to add this field to your flight). You can also add yourself to the Crew Members section in the Instructor position.
Let me know if you have any other questions, or if I’ve misunderstood your question. Since you mentioned “sign myself”, I wonder if you were actually asking about the digital signatures that can be added to a flight. However, these are typically added to the student’s logbook, not the instructor.
