There's more add-on limiters and at least 1 cross connection between the prop governor and fuel governor for redundancy, but as far as I remember the basic blade governing function is the same.

vessbot posted:Everything they said is true, but to answer this part in a nutshell: For every RPM there's a max allowed manifold pressure, (though, as has been pointed out, this is not "square") to avoid exceeding the safe cylinder pressure during combustion; and doing the changes in this order prevents you from temporarily going through a non-allowed combo. Both directions of power change, you're going in the safer direction first. none of this is true unless youre talking about some insane turbo compound engine. NA and esp turbo engines can and do run oversquare all the time and its totally normal for them to do so.

He correctly meant turbo-compound, the late WWII tech of exhaust energy being mechanically fed back into the crankshaft. The only flying engine that features this, the Wright R-3350 has this part removed on all examples due to parts and maintenance, and lack of need (warbirds not carrying war payload). Compound turbo (running 2 turbos with the compressors in series) is not something done in aviation ever to my knowledge (but I have not been following the developments in Reno sport class in the last decade or so).

It's still being used now. Freightliner has it in some engines, but I don't think Daimler is using it anywhere but in North America. Volvo is using it in Volvo, Mack, and Renault engines in at least North America and Europe. They are for fuel economy now, but sometimes an OE might add TC to an Australian engine package for extra power with road trains. Here's the Greg's Airplanes video on it https://www.youtube.com/watch?v=gbMgwDIdScY

This is my first month holding a line and now I don’t wanna do anything else the rest of my life. Got back tired yesterday so I traded my Saturday trip for something easier that starts on Tuesday. No reserve, no whining from scheduling, I’m just off the next 4 days now so I can chill and drink beer. This is the life, man.

Coming from the military, it’s almost still inconceivable that I am completely free when I walk off the jet bridge. I don’t know how some people are always angry or stressed at work. This job is the best. I get to do all my favorite things every day at work: drink coffee, read a book, work out, fly an airplane. I spend every moment of an overnight I can by myself. I love hanging out with the crew but I alone can recharge my batteries and give every moment back to my kids once I’m home (and let my wife relax a bit).

So the kinda of bureaucracy that we would find Kafkaesque would be routine for him. My understanding is that for the last 30 years it was IMPOSSIBLE for Canadian citizens to get immigration papers to be pilots in the United States. It simply didn't happen. The guy who got me ready for my PPL checkride graduated from the full ride at Embry Riddle in the 1980s and in spite of his best efforts it was impossible to get immigration papers in the US. He had to stay in Canada where there were zero jobs. He even offered to work for free and couldn't get a job as an instructor or anything it was hosed. He gave up on his dreams and worked as a Toyota assembly line worker until he got an early retirement from there and is now instructing in his 50s. He probably wont go airline track but at least he gets to do his dream job finally. The 1990s and early 2000s were a terrible time for Canadian pilots. The weirdest thing is that apparently the US will provide visas to people from Costa Rica or something and Australia but Canadians can't do it. Now I have done some preliminary research and already spoke to immigration lawyers in America and they told me it's possible to get a greencard on a national interest waiver visa. In this case if you prove you have some substantial achievements in aviation and are a member of a professional organization (for example ALPA) they can argue your case and get you a waiver. It's called an EB2-NIW visa but after getting excited about it I was told it's not actually that easy to get one and the lawyers are selling me a bill of goods. Outside of that you need a labor market opinion from the US Dept of Labor. Not sure how easy that is to get as historically the dept of labor has always managed to prove an American can get a pilot job so there's no need to authorize a Canadian to get a visa for one. So realistically the best case scenario is that I somehow meet an American woman, fall in love and get married. This skips the bullshit and opens up a possibility to work for an American airline when I got the hours/experience. Either way this plan would be something I handle 5 years down the road when I'm better established in the career... Right now I'm still working on my instrument checkride. This might well be the year where I finally have all my ratings. I have a multi and multi ifr training thing lined up, then I can do my CPL and instructor rating. I'll instruct and then go apply for Air Canada Jazz or something to get my turbine experience. Their requirements are low and the union got a better deal on pay. I can deal with being paid like 60k if I stay in YYZ rent free like I am now. Kraftwerk fucked around with this message at 20:48 on Mar 11, 2024 |

From the European side of things, post covid anecdotally I've heard of some people applying for green cards with the aim of going to one of the legacy carriers in the States. Not heard of anyone who's actually succeeded yet but who knows? It might happen. Prior to covid I'd never come across anyone who tried it.

There's a posting at work for pilots with 600 PIC and Cessna experience, offering $5000/month plus per diem and additional money per flying hour, and then $10k per month to captain a Jetstream on a rotational basis. Housing provided. You just have to be cool with being in Fort Smith quite a bit. I don't think, Kraft, you're being entirely fair to the state of the industry of Canada. It's not quite as bad as you make out, by a long shot.

Hey all, my PPL journey continues. Have done a lot of slow flight, take off and lands, touch n go's, and even recently did my first landing at a different airport. Its so but regular progress. However weather keep cancelling my training days. And because I fly out of a relatively impacted airport, its hard to just reschedule immediately (instead I have to reschedule out some weeks from the cancelled date). So my question is, as I am constantly chomping at the bit for more experiecne, is microsoft flight simulator at all a decent way to scratch that itch/build familiarity? I understand, of course, its no where near a replacement, but I guess my main question would be, is it actively a bad idea that could encourage or have me learn bad practices to jump into flight simulator (which afaict has my plane model and airport) and fly around a bit?

There’s not a lot to be meaningfully gained from a home flight sim at the private pilot level, unfortunately. Flight sims can be pretty good for learning procedures, so if/when you get to your instrument rating, sims can be a good tool for practicing there. As you’ve probably noticed, most of the flight skills you’re developing now have to do with feel and proper visual reference, which a home flight sim just won’t really give you. On the other hand, flight sims are fun and unless you’re already developing some really bad habits in the plane, it won’t hurt, so knock yourself out. You can always go the extra mile and add in Vatsim to practice radio work with sim nerds, too.

I think that it can be useful as an extension of chair flying if you already have a yoke/stick and rudders, but it's not so beneficial that you should go out and spend hundreds of dollars on sim gear. If you don't have that equipment already, spend the money on cockpit diagrams and do good old analog chair flying to practice your flows.

If you still have to do paper navigation and not just follow the magenta line, practicing in the sim is extremely useful. A logitech 3D joystick is plenty for that.

Home sims are great if you use them for what they’re good at. Feel and sight picture will never be right. Practice procedures & radio communications (use PilotEdge or VATsim). They’re also useful for getting familiar with airports and airspace, my checkride was rescheduled to a new location with 24 hour notice, a location I had no familiarity with. I flew around the area in MSFS, figured out the scenery and useful reference points and all the possible diversions. Also I set ridiculously low reliability on my systems and get randomly thrown failures forcing me to actually use all those abnormal and emergency procedures. X-Plane is way better for this. Logitech Extreme 3D pro stick is what I use, I had a yoke but it was too sticky for smooth landings.

Sitting on an a319 that isn't departing because "there is an inoperative equipment or system, which we are legal to fly without, but to do so requires a qualification which none of the pilots have". I can't think of what that could possibly be. They're waiting on a company phone call, so maybe it's a company policy thing, not FAR. Any ideas what could be broken? My best guess is rvsm related, which doesn't seem right.
