I have told this story before:
To convert a Huey/Cobra/Blackhawk Pilot to a Chinook Pilot is simple.
During the first flight for the newbie....one does the old Fort Rucker Instructor Pilot chat while demonstrating maneuvers....the boring kind....and using the most boring tone and cadence of speaking....until the aircraft is light on fuel and you see the Student's eyes glazed over with boredom.
When you know he is no longer listening to you and is day dreaming about being anywhere but where he is....you keep up the boring chat and mention Confined Area Operations....giving the Fort Rucker chat until the aircraft is setting on the ground in the confined area.
Then you begin the Fort Rucker explanation of how to do a Confined Area Takeoff....and at some point the Student gets to say "Clear Right and Up!" as part of the procedure....but he is by now....very...very...very bored.
Then you apply Maximum Takeoff Power....right to the limit....rapidly......and ascend vertically....with your Left Foot stuck well out into the Chin Bubble causing the aircraft to rotate about its vertical axis.....climbing like a Rocket....with some pretty impressive "G" forces due to the acceleration upwards.
As the Student tries to get his chin out of his lap....and finally gets to where he can see out of the Windscreen.....by the time you stop the climb and rotation at 3,000 feet AGL.....you have created a Chinook Pilot!
The sheer power and performance of an empty Chinook is mind boggling!
The rest of the demo is to descend vertically turning to the right....back into the Confined Area and let the new guy try that takeoff for himself.
They are then are properly "hooked".
