Who teaches this, who runs the gate, and who owns the aircraft.
Three people, listed by what they are qualified to sign rather than by photograph. Two of them can stop you flying, and the one who is not aircrew can stop the aircraft flying at all.
Wren Oyelaran
Convenor
Course convenor, former test pilot, and the person who decides whether you are ready to take the aircraft up alone.
Tomas Réti
Tutor
Simulator instructor. He will let you crash, repeatedly, in the only room where crashing teaches you something.
Ida Bergström
Crew chief. She owns the aircraft, releases it to you for a sortie, and inspects what you hand back.
