Constructive criticism I have for Professor Greenspun, after watching many of these videos: I hear very frequent comments about "modern aircraft don't really do that" or "do this, " or "you don't have to worry about this for most modern aircraft today." Respectfully, it seems like you're a bit too biased by your own personal experience, prof. Maybe you and/or the MIT Flying Club have expensive modern planes, but there are a lot of flight schools, flying clubs, and individual pilots around the country who are still using older equipment. So yes, VOR does really matter quite a lot, and so does adverse yaw. Love your lectures, I could listen to you explain this stuff all day long. But I noticed this keeps happening so thought I'd comment. :)

Thank you MIT for doing all of these videos. I'm going for my PPL soon. This is great pre course/course material. :)

Nothing beats a contra-rotating propfan engine. Progresa D-27 is the most impressive bit of engine engineering I've seen, and I work on aerospace propulsion as a job.

Wow! He is absolutely generous as a teacher 💪🏻 please fly here to Denmark and teach me like…. All you know 🤣🤣

"The engine is connected directly to the prop"
five minutes later
"The rotax have a gear box between the engine and the prop"

"Jet-full will damage piston engines"
Well Otto engines yes, Diesel engines no. While rare, diesel engines does exist

Very useful refresher course. Thank you 🙏

What! The FAA call them turbo jets are really turbo fans! that isn't true; the difference is on how that power is deliver as in a turbo jet the core power has the higher rate of thrust, as technology develop turbo fan were engineered and a higher rate of thrust were achieved as more mass of air move due to the larger Fan. The name turbo fan is linked due to the terrific rate of thrust compare to a turbo jet. The J52 turbojet later became the JT8D turbofan.

Cars used to come with directions on how to adjust the valves.

Now they come with warning not to drink the juice out of the battery!!!!

I just wish I didn't have to listen to "ummm" before each sentence..

Is this guy actually getting paid for these presentations?
