A co worker just said that the Squirrels are becoming sentient, and their blood lust is no longer sated by flight crews - they are now trying to murder an entire hospital.

What is it about the Squirrel/Astar (I hate marketing designations with the fury of a thousand suns) that makes it so accident-prone?

Plastic_Gargoyle posted:What is it about the Squirrel/Astar (I hate marketing designations with the fury of a thousand suns) that makes it so accident-prone? There is no one reason. Even though I can't stand the loving things, I will begrudgingly admit that sheer numbers are most of the reason you see so many crumpled up. It's kind of the default light single for anyone who needs a helicopter, be it VIP transport, medevac, news gathering, photography, utility, law enforcement, etc. There are some mechanical reasons too, like a tendency to jack stall (the hydraulics cant keep up with the pilots input) at high speeds with higher gross weights. Speaking of hydraulics, all the models except for the newest B3e only have one hydraulic pump, and it's belt driven like a god drat lawn mower:  When that fucker lets go, there is supposedly enough pressure left for a handful of control inputs. Doesn't exactly inspire a lot of comfort. The first models were powered by Lycoming LTS engines which had a poor reliability record, leading to the nickname "falling stars" or "death stars".

How is an aircraft with such a critical system as a single point of failure allowed to fly?

EightBit posted:How is an aircraft with such a critical system as a single point of failure allowed to fly? Because reasons, basically. Manufacturers are always looking for a way to cut their costs and one of the ways they do it is with the whole "equivalent level of safety" exemption. Basically, if they can prove an otherwise non-compliant component/system will provide essentially the same level of safety as a compliant one, they can use the non-compliant system. Sometimes it works just fine, sometimes it doesn't (like in the case of the Sikorsky S-92's gearbox oil filtration system).

Not as good as redundancy, but the answer is you give the drive a ridiculous service factor. Modern synchronous belt drives, size for size, can have significantly higher power capacity than even steel chain. You can move a shockingly large amount of power for a very long time with a modern belt drive.

Can you fly the squirrel or whatever it is hydraulic boost off? If you can't, it seems pretty stupid that it isn't a redundant system. I'm guessing you can't since its four bladed. Is that belt driven off of the transmission or the accessory box? My only exposure to small helicopters is the 206 (H-57) and that thing is pretty fool proof. you could fly it boost off, which while slightly uncomfortable was easily doable, especially at lower speeds. And the hydraulic pump for it was geared off of the transmission accessory, which if you lose that you have much much bigger problems.

Is that belt driven off of the transmission or the accessory box? The Squirrel is three bladed, and the hydraulic belt drive is run off the main rotor gearbox. In response to criticism (and smoking craters in the ground) the newest model is equipped with redundant hydraulics - one gear driven off the transmission, the other belt driven like earlier models. Flying the Squirrel with the gorillas off is nothing like a 206 or 407. The control forces are very high, and god help you if you use up the accumulator pressure before you get the thing pitched back down to 60kt IAS.

BAE Systems released some drawings done by British Aerospace engineers in the 1960s for poo poo they wanted to make but couldn't because it was [a] batshit crazy [b] a bit pointless [c] impossible This awesome looking thing is the Intercity Vertical-Lift Aircraft, a passenger jet with VTOL capabilities so you could put airports in the middle of crowded city centres, to give everyone the pleasant experience of living next to an active runway. I think the idea was to compete with high speed rail or something. In this drawing they've decided a great place for an airport would be Battersea in south west London.  This is the Fighter Jet Take-Off Platform, which was a sort of strap-on VTO  This peppy little bastard is called the MUSTARD, the Multi-Unit Space Transport And Recovery Device. Why have one space shuttle when you can have three, strapped together! All of them would be crewed, launching as a single unit the outer two would act as boosters, separate and then fly back to land while the central one would go into space. 1960s engineers: very concerned about recycling, don't give a gently caress about complexity and weight.   MOTHER loving JUMP JEEP 12 vertical lift fans attached to a 4X4 so it could clear enemy obstacles, and then sink into any marshland, sand or mud because of the weight required to carry the propulsion system needed for 12 fans capable of lifting a land rover. Also, with the low ground clearance, it'd get stuck the first time it had to go over a hill with the fans out of action.

All of those are awesome, you hater. In a couple months I'm going to get a chance to take photos of a flying/flyable F7F Tigercat (among other things) which is on my shortlist of "hell yes" - didn't someone here make a nice how to take photos of prop aircraft post? Powercube? I want to make sure I get it right. I shoot with an aps-c Canon and can rent whatever tele/supertelephoto so lens suggestions also welcome.

On the other hand, JFK is fairly well known online for having pretty entertaining controller interactions with aircraft, so it's worth looking some other videos up of them too.

One big mistake that guy made is asking a question that could be mistaken as a control instruction. You flat out can't do that with a lot of foreign pilots. They're listening for certain words, and when they hear them, they take it as a clearance and go. You either give them an instruction or you don't.

We have a controller who is now infamous for asking a Yankee Victor (Venezuelan registered aircraft, notorious for being hard to deal with, and having poor English skills,) to switch to a different frequency and relay something to another aircraft... It didn't go well.
