Godholio posted:Typically you fly things on a C-17 because it's better than driving/shipping them. That C-17 was loaded when it landed, and had to be unloaded to take off. In addition to transporting the cargo, you also need to send the AF cops over to guard the stupid thing. And yeah, possibly have the runway inspected for damage. Why would it need to be guarded? I mean I saw two UH-1Ys at CMH this morning, with (empty) rocket pods, no less, just sitting by themselves.

The other guy was setting up for a straight in to the airport, called runway in sight, was just about to flare, saw that the ramp was lined with fighter jets and started climbing again. That happens the other way ‘round, too: https://www.flyingmag.com/news/cause-c-17-landing-too-small-airport-revealed/ quote:Rather than touching down at its intended destination — the MacDill Air Force Base (KMCF) in Tampa, Florida — the large cargo airplane landed at the Peter O Knight (KTPF) general aviation airport. KTPF is located about five miles northeast of KMCF on a similar albeit significantly smaller peninsula. The runway heading would have indicated to the pilots that they were approaching the right airport as both airports have the same Runway 4-22.

In this scenario it’s important to remember the FAA are cops, they may just want to yell at you but they could also do anything up to revoking your license and referring you for prosecution. https://www.aopa.org/news-and-media/all-news/2008/june/flight-training-magazine/cfis-and-the-g-man

Theoretically the FAA is compliance focussed. If a serious phone call gets you on the straight and level, that can be the end of it. If you’re a repeat offender and blowing them off, they’ll take off the gloves.

atomicpile posted:Raptor man has new aircraft project. Early reviews are coming in (on Youtube) and quote:tell me you have real engineers working on project this time. quote:Sooooo...what was the point of all those flight test hours on the first version if you were planning something completely different? Is any of the data you gathered useful for the program going forward with a different airframe and powerplant? quote:Unconventional powerplant/propulsion, untested novel aerodynamics all being developed simultaneously by the guy who brought you an obviously overweight, underpowered conventional platform underperforming airframe. The powertrain can be iron birded but there’s no way to developer the airframe independently of that great experiment. My advice to investors,”Raise handles, squeeze triggers, eject, eject, eject.” Glad only the corn got hurt. quote:Wow. Rather than beginning to reduce the weight on the first design and at least try to get a kit to those who have actually paid, you jump into the next prototype of a completely different design that will use an even less proven propulsion system. So much for those people who have faithfully left their deposits expecting improvements on the original design and an imminent delivery. quote:I know for a fact that you have taken a ton of money from people as a deposit for "version 1" of the raptor. I know someone personally that has given you like $10-$20K years ago for one. Are you giving them there money back now that you have completely changed the design and direction? I can tell you for a fact that the reason my friend put the deposit down was because it was pressurized. This seems like a full on grift now. they're mixed. It's about 50/50 between stuff like the above and "wow cool keep moving forwards!!"

To be fair, electric propulsion is a hell of a lot simpler than an internal combustion engine, but given how the last project went, I half expect him to somehow manage to get CO poisoning off an electric motor.

I found the flight track for the crash flight, incidentally: https://flightaware.com/live/flight/N352TD/history/20210806/1058Z/KMHK Does anyone know why he decided to fly this thing cross-country at less than 1500' AGL? He doesn't hit more than 3000 MSL at any point, doing most of it at 2700, and the terrain along his path varies between 1000-1600 MSL. Is it so seriously underpowered that it just...can't climb any higher? Mega oof

Huh. Patey flew his plane with an airboat prop and it wasn’t a complete disaster. https://www.youtube.com/watch?v=qqTY446hXzs He talks about the prop about seven minutes in. It’s limiting his cruise performance and he’s working on a custom replacement, but that’s farther than I thought he would get with it.

He doesn't hit more than 3000 MSL at any point, doing most of it at 2700, and the terrain along his path varies between 1000-1600 MSL. The engine cooling system Muller designed doesn't do much. He can't run the engine at max power settings for very long, whether or not he's in the air. The early flights which weren't cut short by the wobbling were cut short by the inevitable overheating emergency. He came up with a bunch of rube goldberg tweaks, including running the cabin heater at full blast (lol), but none of it was enough. So he worked up procedures which let him stay in the air longer and gave the illusion of forward progress: take off early in the morning when it's cooler, climb at an anemic rate, watch temperature gauges like a hawk, level off and reduce power further as soon as they get dangerously high. That's why he was cross-countrying so low and slow. Nobody should be taking an airplane like Raptor up at all, but if he absolutely had to, he should've been staying within glide range of a runway at all times, not trying to limp that pitiful thing over terrain. This crash was next-level getthereitis.

Gliders are using electric engines more and more for maintaining altitude though. Only type certified electric I could find: https://en.m.wikipedia.org/wiki/Pipistrel_Velis_Electro I expect there to be more as time goes by though. Electrics make sense for small trainers.

That plane is optimized for short field performance and not cruise, that's the fundamental stated design goal. Mocking a component that works toward that end is like mocking Airbus for their abysmal lack of sand bar landing features.

I don't know what the C-17's specific requirements are, but every military aircraft has a security requirement. At least on the USAF side, and probably in every service, there is classified material or equipment. It could be as simple as the crypto for secure radios or computer equipment or it could be the physical aircraft itself (ie F-22/F-35). My E-3 diverted to a civilian airport due to thunderstorms cutting us off while we were out over water and unable to get to any military installation, and we had to leave crewmembers with the jet for several days until we could leave again (because the local-ish ANG unit refused to send over a couple of cops). Each service has their own standards, and some are more lax than others. Edit: As mentioned, either somebody had eyes on those helicopters, or their requirements are low/waived low enough that whatever inherent security the airfield had was sufficient. It's possible that airport has some kind of arrangement since it's managed by the same company that overseas Rickenbacker, which has a military presence.

Mocking a component that works toward that end is like mocking Airbus for their abysmal lack of sand bar landing features. An airboat propeller like what he’s got there isn’t optimized for short field performance, it’s optimized for static thrust to move a heavy boat across all manner of surfaces (not just water,) and to resist debris damage. Maximum push at zero relative wind is king in airboat props, but with that in mind, racing airboats still use ground-adjustable fixed-pitch props that look suspiciously like airplane propellers, since they want to deliver peak thrust at higher relative wind speeds. A max-effort STOL airplane is going to have a ground-adjustable fixed pitch prop to save weight, but also allow you to use the airplane for other things. Given the rest of that airplane, a constant speed prop with a really aggressive STOL-oriented blade design makes total sense, and I have no idea why he threw a loving airboat prop on there in the first place, except maybe for the YouTube clicks.

I remember way back when, my father pulled some strings and allowed me to play around in the MH-53E simulator at Norfolk (they turned full-motion off because they were afraid I'd puke or go "full kid" and potentially overstress the hydraulics with wild movements). They had to put a glorified sock over the control panel for the minesweeping gear even though I was ten at the time. Obviously some poo poo has changed because in this video they just kinda-sorta cover it with "keep the gently caress out" tape: https://www.youtube.com/watch?v=iGEGemv73v4
