Boeing 747 Reverse thrust operation

Hello! How do you do everyone. Today’s video is about 10 minutes long and I hope you will watch it through to the end. I know that the majority of people can only handle 2-3 minutes before moving on but I assure you that you will not be bored if you are an aviation enthusiast 😀
The video today teaches about what happens externally at the engines when a pilot selects reverse thrust. Then I show you what goes on in the cockpit to make those things happen. Most modern large jet aircraft have thrust reverse systems to aid with aircraft deceleration after landing or in a rejected takeoff. Some an even use reverse thrust to back up the aircraft (not authorised on B747). On some engine types, reverse thrust is selectable in flight- usually just before touchdown. The important thing to note is that reverse thrust is all about the direction of the thrust. The engine does NOT start spinning in a reverse or opposite direction! All that happens is that the thrust that would normally be pushing the aircraft forward via the exhaust, is redirected forward in an opposite direction to the aircraft direction. This results in aircraft deceleration- similar to what boats do. They redirect the water forward as they approach the docking point to slow down. I have the usual captions of course and I do my best to indicate what is going on- have a watch and I hope you like it. At the end, see if you can recognise when the pilot selects reverse thrust after touchdown- enjoy!
