How Do We Get a Plane in the Air Without Taking Off?

Thank Carl, for showing us this wonderful video!

Beautiful plane! 😃

The fellow in this video stated the onboard hydraulic pimps wouldn't retract the main landing gear and close the doors? Why? Or in flight are there different hydraulic pumps run by the engines that are used? Just seems weird. If the onboard electric hydraulic pumps won't do the job I would suggest a gear reduction hydraulic pump for emergency retraction of the landing gear. Might be a wee bit slower than the normal pumps but better to be able to retract the gear and close all doors. Or you could go back in time for emergency hydraulic power to utilize a prop driven emergency hydraulic pump using the wind going over the airframe to run the hydraulic system. I seem to recall ram turbines have been used on military and civilian aircraft before. Why have the complexity of electrical systems when you simply pull a handle connected to a cable to release the ram turbine out of its storage position and into the airstream to provide emergency hydraulic power. Merely my simply observations and thoughts on how to rectify a potential loss of aircraft flight and gear controls though I grant you it wouldn't be as high a volume of hydraulic oil pressure it would still give the flight crew control, just not at the speed their used to. Just playing devils advocate. Cheers! ( and may none of your flights ever require emergency equipment like I have described.)

Awesome! I was hopping it was gonna be the 787! 😬

I was once told, if I pick up a fly and throw it up in the air the fly will retract it's legs. IF I can pick up the 747 and throw it up, will the gears retract automatically?

No. There's a switch in the flight deck that raises and lowers the gear. That would have to be in the up position for the gear to retract. Funny hypothesis though!

Do you guys do school based apprenticeships in Brisbane
