Professor and department head for the School of Aeronautics and Astronautics at Purdue University Bill Crossley answers questions about airplanes and aerospace engineering from Twitter. How do airplane wings generate the necessary amount of lift to achieve flight? Can a plane fly with only one engine? Could electric airplanes replace fuel-burning ones? Is severe turbulence still safe to fly through? Why do commercial planes fly at 35,000 feet? Are planes safer than cars statistically? How much does it cost to build an airplane? Answers to these questions and many more await on Airplane Support.

I dunno, ramps sound like they would help with both getting planes up to speed fast as they start (driving down the ramp), as well as with braking during landing (driving up the ramp), thanks to gravity help.
my guess? because wind changes direction
You don’t have to be a professor to answer all those stupid questions. You only need some common sense and a very basic understanding of physics…
If too many G’s cause pilots to black out, cause the blood can’t reach their head, why don’t pilots lay down, or even fly upside down with inverted views?
such a dumb qns… if u have a ramp then u won’t know if the plane is able to take off by itself right? and if it isn’t ready, then its gonna fall off the ramp?
I have noticed that things on aircraft are sometimes massively over engineerd
such as a chunky steel bracket just to hold a cable still
When it would weigh so much less to be something like plastic
or even be glued to the super structure
11:37 Did the professor not understand the question he was giving an answer to ?
Remember when you used to hear airplanes flying above everyone must stop and look up in the sky. I remember being a kid and totally falling out of a trampoline because I was staring up.
10:30 Airports DO have ramps. They are also called aprons.
Last thing i want as a passenger is to be transported on a drone. How can i trust a pilot that isn’t in the plane woth me.
747 and 7 what 7????????????
6 7 🤑
to answer the question on the thumbnail, look up admiral Kuznetov
I think we all really know why there’s a lack of controllers
Why don’t we have nuclear powered airlines yet?
probably because they need special crew to maintain it , aswell as it just being complex , its far cheaper to have a regular jet like we have now , and we haven’t researched / developed any nuclear engines that can be fitted onto planes , which is probably the key part
B😊
They could have a ramp. We don’t do ramps because it’ll wreck suspension on the landing gear. Part of why the US does steam launching with level decks for our aircraft carriers. That and length of launch distance. We run angled decks so could launch 2 as one lands. Nuclear powered so we can run them the next 50+ years without repowering. Oh we also have non nuke carriers LHDs-the LHA. 25? carriers? Good luck friends – we primarily do war as a money maker.
What are the odds of both engines failing on an 8 hour flight for the least reliable engines in current service on commercial jetliners? Assume that operating conditions are average and that the engines are in the last quartile of their useful life. I am not interested in an answer like “astronomical”; I am interested in a number that the person answering has 95%+ confidence is correct to within less than an order of magnitude.
How much of a premium, in percent of the lower price, would you pay to fly across the Atlantic on the safest commercial jetliner operating that route vs the least safe one on the same route?
When talking about electric planes why didn’t he talk about reducing pollution which improves human health and mitigates climate change? Very strange to have left that out. Electric batteries are way less polluting, even factoring in their manufacturing process.
No statistic will ever convince me that airplanes are safer
