So, those cable-cutters on helicopters that are supposed to, in the event of a wire strike, cut the wire. You know, these things: Do they actually do anything useful in practice? I mean, is there a body of incidents where helicopters struck a wire, the wire was cut by this cutter, and this averted a crash?

So what’s the proper thing to do there? I assume he radio’d for an emergency/immediate landing as carrying around a 10 pound potential projectile is a bad look.

In the comments, the pilot relays that he had a hilarious exchange with the tower. I was concerned about the cat wigging and jumping, or making her way into the fuselage & adding her mass to the tail.

You know, these things: Yes https://www.verticalmag.com/news/raf-chinook-lands-on-welsh-farm-after-striking-wire/ They aren't going to add weight to helicopters that doesn't do anything and you can see it on virtually all the B212s parked at the firefighting company next door to my flight school. Wires are the biggest cause of accidents in North America (In Canada, weather is the leading cause, with a close 2nd).

ImplicitAssembler posted:Yes That's a Chinook that struck a wire. That's not a Chinook that struck a wire and had disaster averted by the cutter. RAF Chinooks don't even have them installed, and there isn't one in the picture. I wasn't asking if helicopters strike wires, I'm asking is there any evidence that the wire-cutters actually do anything useful when helicopters strike wires. quote:They aren't going to add weight to helicopters that doesn't do anything FAA says there's no evidence they do anything: http://www.tc.faa.gov/its/worldpac/techrpt/ar0825.pdf quote:Figure 5 shows that the annual number of wire strike accidents decreased after 1990. Between Wire strike fatalities went down after they were installed, but wire strikes altogether went down after they were installed; the report suggests that installing them increased awareness and that this increased awareness led to fewer wire strikes. But are there in fact cases where a helicopter strikes a wire and the cutter does what it's supposed to do? ImplicitAssembler posted:Wires are the biggest cause of accidents in North America (In Canada, weather is the leading cause, with a close 2nd). Paper claims that "Wire strikes only constituted about 2% and 3% of all the helicopter-related accidents during the last 3 years (2002-2004). This rate is better than the corresponding rate for civil helicopters (between 4% and 5%)." Phanatic fucked around with this message at 23:17 on Sep 17, 2020 |

On my preflights I grab the wing and rock it up and down a few times, both to ensure that it's attached firmly to the fuselage and to listen for any rattling nuts or bolts that might have come loose inside. I haven't had any cats come running out yet, but I hope to someday

Wires are a category of obstacle that includes too wide a range of things to be reasonably mitigated by one installed system. In my career I’ve been adjacent to two strikes of horizontal wires (by other people): in one the aircraft struck at such a nose-high attitude that it missed all cutters but the cable snapped under the force of the airframe; in the other the cable was strong enough to destroy the part of the airframe it was supposed to ride along until the next cutter would snag it. Seen a lot of vertical wire strikes (tethered blimps) where rotor blades won in every case. That said, the weight difference of a WSPS installation is easily within the range of fat vs skinny copilot, so I’d rather have it just in case I run into something cuttable by a paint covered steel edge.

We were doing some Chinook testing right near (at? Adjacent to? Never really was clear on the exact location) Porton Down and as we left we flew near the artillery range while they were doing live-fire. It was getting towards dusk so you could see the fireballs at the impacts. We weren't overflying the range so they weren't bursting right beneath us but goddamn did it seem like they were. That was so loving cool to watch from the ramp.

It's a few years old now but that's a brave cat too, crazy. I guess the winds are the opposite way today, I saw a Dreamlifter turn over me going into Everett, and I see they're doing North landings there and SeaTac. Also can you do this?  Also also: If you see one of the planes flying around in green, it's just the 737 going from Renton to Everett for paint, right? I didn't think they flew any of the others in green wrap.

You mean can you fly straight over SeaTac? Sure, as long as you get clearance for the transition -- SEA is class B airspace. Call up approach control before you get there, tell them where you're going, and they'll let you in unless things are really hectic. Flying straight over midfield is a relatively common type of transition because it's an area that is, for obvious reasons, usually clear of approaching or departing aircraft. Trying to fly "around" the airport and crossing the extended runway centerline is potentially much more dangerous. The green "wrap" is actually a chromate primer, and yes, a plane that color is almost certainly being taken to the paint shop. Sagebrush fucked around with this message at 02:56 on Sep 18, 2020 |

From that link "Thus, assuming that the trend of the past 10 years continues in the coming years, and assuming that all the wire strike accidents occur in conditions when it is most effective, equipping helicopters with WSPS can reduce about 44% of the fatalities. However, this is an overestimate because most of the accidents occurred during the climb and descent phases of flight and involved wire strikes of the main rotor system, the tail boom, or the vertical tail." I did have my numbers somewhat crossed...Wire-strikes has some of the highest number of fatalities, not necessarily highest number of accidents. The 2 main things that are getting beaten into us at flight school are: - LTE -Wires A lot of our flying here in BC is in a mountain environment which is also a wire environment.

Oh yeah I guess it's a lacquer, but I mean, do they actually fly any of them like that besides the 737? The rest are built in the same place as the paint shop I think. The 737 has to make it from Renton to Everett though.

The facility had a couple of brand new 787's roll out in Norwegian and El Al liveries that sat outside for several weeks, presumably while various lenders argued over where the airplanes were supposed to go after their parent companies essentially vanished.

That was so loving cool to watch from the ramp. I was doing a night flight for my PPL heading south towards El Paso, TX. If you look at the chart, there's a tiny corridor over a highway that cuts through the middle of White Sands Missile Range and Fort Bliss artillery range. That night, there was live-fire artillery going on; from 4500 AGL I could occasionally see tracers at my altitude. I decided to up the altitude a couple thousand feet, even though it was too cold already.

I flew directly over LAX like a dozen times in a POS bug smasher using the SVFR corridor. You just tell ATC you’re going to use it, then you fly a very exact line at an exact altitude squawking VFR and they tell you good luck and cancel flight following. You pop out the other side of the bravo and get picked back up by center. Easy peasy, but pretty spooky. I’m assuming they have similar corridors through every major bravo.

There's no tracer artillery projectiles I'm aware of in the us arsenal. http://uxoinfo.com/blogcfc/client/includes/uxopages/Mulvaney_Details.cfm?Ord_Id=P196 If it was illumination rounds, the projectile actually gets even higher than the visible illuminated bit that is ejected. I don't know how much higher, but I do know that to fire them the cannons are pointed almost straight up That said maybe it's possible the heat is sufficient to produce light on some projectiles? Maybe? Though I'd think that cools off pretty rapidly in the air. I've seen a lot of them go but rarely in flight. Best Friends fucked around with this message at 06:10 on Sep 18, 2020 |

Charles posted:Also can you do this? Thats a specified transition over SeaTac in the Seattle TAC chart for VFR traffic (you can see it on Skyvector.com). You get clearance from SEA tower. The first cross country flight I ever did was over the runway like that after departing Auburn and heading West which was way cool. And the green 737s are out of Renton to Boeing Field where they sometimes get painted. They're all primarily done in Renton right now with the slow down. None go to Everett, currently, or elsewhere for paint. If you saw it yesterday out if BFI, it's a BBJ MAX that will get painted after delivery, whenever that may be. It's just doing some production check/test flights. There's also a disturbing report I just heard about from the DOT for Southwest Airlines that they had serious and frequent weight and balance discrepancies on flights as well as poor maintenance practices, or lack of, on used jets purchased from foreign carriers. The FAA knew all this and didn't bother to really deal with it, so that's a bit concerning to learn. https://www.oig.dot.gov/library-item/37731 AzureSkys fucked around with this message at 07:40 on Sep 18, 2020 |
