bird strikes? when i was in the AF back in the mid 80s, our maintenance magazine showcased a strike in California, where a deer ran onto the runway as an FB-111 was taking off – wrecked the aircraft and (of course) obliterated the deer, but in fairness, the crew chief got to paint a little deer silhouette on the side of the cockpit when the plane returned to service.

Why don’t more planes have wings mounted on the top of the fuselage? it would seem to prevent engine strikes, and make for a simpler connection with the airplane compared with wings mounted halfway up the fuselage

It’s because they have better aerodynamic efficiency and provide better stability being mounted lower on the fuselage.

I still see aircraft passing overhead and can only hear them on a very quiet day. I also see contrails that are smaller and go away faster too. When I hear that old roaring sound in the sky 9/10 chance it’s military.

10:26 Ramps like some carriers: you wanna start your plane into the wind, so ramp into the wind. The aircraft carrier can turn itself into the wind, so the ramp can always be pointed into the right direction. An airport runway cannot. So it’s useful that the runway can be used in both directions, depending on the wind direction. The ramp would ruin that.
@kenbrown2808
September 11, 2024 at 1:05 pm
it is POSSIBLE to fly a modern passenger jet with only one pilot, but the presence of copilot allows the pilot to share his workload with the copilot. in essence, during the complicated parts of the trip; specifically takeoff and landing, the pilot flying does all the things directly related to controlling the airplane, and the pilot monitoring does everything else, like talking on the radio. (and for those who don’t watch aviation youtube, the common terms for what used to be pilot and copilot are pilot flying and pilot monitoring – and the two or three pilots on a plane, depending on the length of the trip, will trade roles during stops on a series of short trips, or at specific points during a long trip)
@kenbrown2808
September 11, 2024 at 1:08 pm
cool aviation fact: the DC 3 was submitted for a request for a THREE engine plane that could maintain altitude with one engine out. they produced a two engine plane that could gain altitude with only one engine running.

1:15 Fun fact: the amount of G-force experienced in a (constant speed) turn is 1/cosine(bank angle), and commercial planes normally never bank more than 30 degrees which translates to only 1.15 G, barely more than the 1G experienced in straight and level flight. Higher G-force than that may be briefly experienced during take-off, landing, or turbulence.
@stoobydootoo4098
September 11, 2024 at 6:35 pm
And it affects the stall speed (nothing to do with speed, actually). Eg, if a light aircraft’s clean stall speed is 50kts, it will stall at c 70kts in a 60* banked turn with power off if it tries to maintain altitude. Square root of the G load.

The only thing I’d disagree with is the idea that airliners really only need one pilot. It’s not that flying the airplane is hard, it’s just the amount of tasks you have to complete at both ends of the flight.

Re: black box material: crashes that are that devastating to the aircraft probably wouldn’t become more survivable if they were made of blackbox material anyways.

I heard a story (apocryphal?) that an old boss of Boeing was asked many years ago why he only flew on 4 engined aircraft. He said, because there are no 5 engined ones.
Also, I was a young passenger on the old HS Trident aircraft in the 70s a few times. It was reputed to be underpowered even with 3 engines. Pilots used to joke that it didnt actually climb on
take-off – it just flew straight while planet earth curved away beneath it!

There were some seeming omissions here. The 757 was glaring. As was the statement that fighters can pull “up to 6 Gs” which I’m sure makes Viper pilots cringe.

Can answer 1. While adhesives are used in building the structure of a lot of aircraft the wings are generally held on by lugs and beams connecting to the main fuselage.
Wings are generally attached to a structure called the “wing box”.

Sizing is fairly similar to that by most clothing brands, so no issues there. A bit loose, but that was what I was aiming for. Not a fan of the V-neck as I prefer the round-neck, but seems ok so far.
The fabric seems quite soft and comfortable, at least before I wash them next. Presumably due to the viscose fabric.
If there are any wear-and-tear or quality issues with the fabric, I will probably update this review to complain. So far seems ok.

For COIN warfare where you only fight against rebels without an airforce of their own, it is wayyy more logical to have propeller planes outfitted for ground support since they are more efficient and require much less maintainance.
Your planes are not gonna get attacked by modern weapons anyway, so efficiency is key. That is why some Latin American and Asian countries still have them, leaving aside the poverty factor.

Converting to electric: people just don’t appreciate how much energy is in a gallon of gas (or jet fuel). JFK flights consume more energy than the entire state of NY uses electricity PLUS converting 95% of the state into a solar farm. And that assumes the planes with like fuel planes not heavy like batteries AND get lighter as they fly.
On the bright side, there are several technologies to make batteries more efficient and lighter about 5 years out.
On the down side, they have been about 5 years out since 1999, and you still have to generate all the electricity somehow.

I have a huge problem with that statement. While yes statistically planes are safer but that doesn’t take into account many factors that make people feel safer in a car than in a plane. In a car you have some control over your fate, by driving safe following good safety practices you will not be a part of the 10s of thousands of fatal annual car accidents. I’ve been driving for over 11 years with not a single serious car accident which is unlikely based on the statistics. They might say that you have a 5% percent chance of getting into a car accident while it’s only 0.01% chance of you are in a plane. But the reaility is that reckless drivers might have 20% chance while safe ones have less than 1% and they are average is high.
In a plane you have a 0.01% chance of having an accident, but if you have one you have a 0.01% chance of survival.

Another thing to know regarding the need for two pilots is that on take-off and landing, the two pilots will usually split duties, with one responsible for flying the plane and the other responsible for monitoring the flight data and communicating with ATC.

The “2nd pilot” is NOT a backup… 2 people are needed to fly and task manage multi engine commercial aircraft.

This is so interesting, but I had to look the other way while listening to this video. Wired video editors constantly switched the video zoom back and forth to try to keep brain attention, but it was very distracting for me.

What about a gas and electric combo plane? They should use the battery till it drain of power and then switch to gas during long flights. Would save a lot of money on gas

I don’t care how safe airplanes are, I STILL WANT A PARACHUTE! You can’t just pull off on the side of the airway like you can off the side of a road. Stated another way, a car may fail more often, but I can ALWAYS pull off to the side of the road. But unless the plane is 100% safe (which is impossible), when that one time in a big number happens, you NEED to have a plan B, and without a parachute, there is none.

Why can’t airplanes be compartmentalized for parachutes?
We don’t need the cockpit, wings and engines, tail, weels and gears, fuel luggage etc etc. That’s a lot of weight off that we don’t need.
Divide the seating section into three or four smaller tubes and chute them separately. When humans can drop 50 ton battle tanks off of planes, weight of 30-60 people (plus seats) per section can’t be an issue.
Obviously not an expert, the design and functionality would be complicated, but it’s worth a try. And I think it’s just the ignorance of the airlines because they wanna profit, and all their investments would go to waste if a plane came out that can 100% guarantee the survival of its passengers and crew in case is a crash.

To add to the fact that airplanes are statistically safer than cars, think about the fact that about 2.9 million people fly EVERY DAY, yet airplane crashes are rare.
@MrKockabilly
September 16, 2024 at 8:25 pm
My question is: Why don’t airlines install CCTVs in the passenger and pilot cabins that would stream and save videos to storage centers on the ground. That would be very critical in incident analysis (hijacking, plane crashes, etc.). I believe current technologies would make that very feasible and cheap. For privacy issues, I believe the passenger cabin – with hundreds of passenger – is a public place. Also, saved footage are only for consumption of the airline, used only if there were incidents, and discarded after an ordinary and uneventful flight.

The reason we don’t use eupersonic is because we don’t need it. We don’t need the max speed to be nearly that high. It’ really expensive and much more inefficient.

I think the name “G forces” gives the impression that they are somehow special kinds of forces. They aren’t forces at all, but accelerations and simple accelerations at that. The acceleration could be measured in any suitable units. Multiples of g is just a handy single digit scale. Imagine if your trip to the beach was measured in what people call “mile horsepowers” instead of “distance.” First off distance doesn’t have to be miles and horsepower isn’t a measure of distance. But we call them “G forces” despite that that phrasing has the same issues.

Actually the turbofan engine was invented in the 30s and widely adopted by airliners more than 50 years ago. The incompetent engineering still makes aircraft electronics super heavy for no reason so there has largely been jack improvement in the last 50 years. And he’s equally wrong on parachutes for large planes. It wouldn’t take up too much space or weight, they just don’t want to do it.
