You Know you have made it when:
u walk up more than 3 steps to enter your aircraft
You can walk between the seats (GA-8 excluded)
You no longer enter A0__ on the flight plan
The only pistons on the aircraft are in the hydrolic system
Last but not least:
you really know you have made it in aviation is when the only problem to do with ice is when the trolly dolly put to much in your coke
