Five Facts from Principles of Flight (ATPL Theory)

Have you heard of the "coffin corner" of a flight envelope? And do you know what critical engines are? Principles of Flight is one of the largest subjects in ATPL theory, and it's definitely also one of the tougher ones! It covers everything from lift and drag generation, limiting speeds, controllability and maneuverability and so much more - but here's five short & interesting facts!

Thanks for watching, and if you have any feedback or questions, just let me know!

Quick note about the coffin corner I forgot to mention: Whilst the information I say in the video is technically correct, in practice the critical mach number may not actually be the issue, since it can be lower than Mmo (Mach maximum operating) on modern swept wing jets. The shock induced separation and stability problems occur above the drag divergence mach number, which is the speed you really want to stay away from!

Pilot Jonathan = new favourite aviation channel. Your videos are both incredibly education while still being easy to understand and also very inspiring! I'm 20 years old and have been saving for my flight training flat for 4 years now. I hope one day I can be in a similar position to yourself. Thank you mate for your hard work and inspiration.

these videos are so interesting, thank you! it was my dream to be a pilot but unfortunately I'm deaf, so instead I love watching these kinds of videos so I can feel involved in the aviation world. my new favourite channel, thank you ‪♡‬

Hey, great vid once again. Watching your vids lately does help me feel motivated in my studies though it's about programming/coding but somehow I think it still relates to aviation a bit in terms of programs or softwares that are used in planes nowadays. Anyway I have a question, how can you possibly get out of the coffin corner safely if you happen to be caught in it?

Wow, great video! Your channel is growing fast! Do you need a video editor?

Hey there, just found this channel. I am little confused are you Lithuanian flying for LOT, or polish training in Lithuania? Thanks 👍

Nice vid would also love to see some X-Plane 11 or MSFS that would be cool

There NO Lift `force` and NO Drag `force`, it is Aerodynamic force. Lift and Drag are just components in coordinate system.
