I'm not sure what to think of all this. I understand the "large airport, blend in" scenario, but you would think people who work that airport on a daily basis would notice him there and realize that he isn't ever working. I'll give him credit for one thing, he sure has patience. I've spend...
Jump to postI'm thinking it would be the same on the 300 as it has the same engines as the 200. Are you thinking longerons rather than frames? I've seen the longerons replaced on the 300 and it's easily done during a "C" check. It's a bit of surgery and a lot of rivets, I'll give you that.
Jump to post"If you win the lottery and buy an aircraft, just recall the cost to own it and maintain, insure, and store it is about 30% of the purchase price per year." While I wasn't aware of the exact numbers, I know maintaining an airplane isn't cheap, but being able to do the work myself (I have a...
Jump to postI've always said if I could afford an airplane of my own (ie won the lottery), it would be a turbo Beaver on amphib floats. As an AME I could still do my own maintenance, just have to get someone to teach me to fly the thing!
Jump to postI still find it amazing that the Beaver is in such a high demand, still the same way it was built in 1947. I'm sure there were minor changes over the years, but I think, largely, the design of the Beaver was mostly the same for all of it's production run (the biggest exception being the turbo beaver...
Jump to postI hope you guys are right about life returning to normal....I'm getting tired of life being this way.

I would think there is a legal requirement for Boeing to support their fleet for a certain timeframe. There is a warranty period (probabl...
Jump to postI'm thinking it all comes down to cost. If an airline or cargo company wants enough to make it profitable for Boeing, then they would make it work. As long as Boeing holds the rights to the 747, in theory they could build one at any time, but generally the cost of doing so is prohibitive. Having sai...
Jump to postI'm confused about the title of this thread. Why is 747-8i in the title?
Jump to postYou are right about that, the problem is that many still think Air Canada is a crown corporation and still getting those taxes/fees as well. I would really like Canada to reduce these fees so that the airlines could make a better recovery post covid. Some will say that the airlines will just raise f...
Jump to postIn my opinion AC_B777 writes one of the most accurate posts in this entire thread. It's been my observation that the more successful a company becomes, the more some people dislike them. As for the past, reverse only takes you one way, backwards. People can keep dredging up faults of the past, or mo...
Jump to postI don't know who would find it, but I'll volunteer to come down there and replace it for you.
Jump to postI'm not a pilot, I'm an AME, but here's why I think it's this way. While I think I could probably do a more thorough walk around than a pilot, he/she is the one flying the plane and I know if I was a pilot, I'd want to have a look before I took it into the air. Another reason is that many stops duri...
Jump to postThen you'll have to find the keys for those 10 to move them first. Maybe some of them have remote start to warm them up or cool them down for more comfort. Now, to be a little more serious about the question, the length of time to get the aircraft back in service depends on the length of the storage...
Jump to postI'm guessing they paint the blue patch with "American" in it first because blue is a horrible colour for hiding. It's easier to paint white over blue than visa versa.
Jump to postGood question, if you gave me the key, I still couldn't find the ignition to use it in! We have had engineers at work telling apprentices to get the key for the Dash 8 so he could run it, not sure if the young guy fell for it or not. As for how to find the planes, I'm sure the facility operator just...
Jump to postSmells much like diesel fuel burning which a college instructor of mine used to call "the breath of life". I like that smell as well, although my wife doesn't. She tells me that she can tell when I've been around running airplane engines because she can smell it on me. The CRJ apu is one o...
Jump to postThe #2 engine is generally started first on the Dash 8 during push back, or during maintenance runs. The #2 hydraulic system powers the park brake on the Dash 8, (all of them). Even with the prop feathered, the engine driven pump (EDP) produces 3000 psi, so no problems with the brakes. Once the #2 i...

Jump to postI was told on my maintenance endorsement course that it was done intentionally to lower the forward exits and overwing exits in order to avoid having to use emergency slides. While I can't be 100% sure of this, I can say for certain that there are no slides on any CRJ at least up to the 900, I'm not...
Jump to postIf there is a failure of one (or more) of the seals in the compressor, there is the possibility of oil getting into the bleed air system. This, in turn, travels to the air conditioning packs and the heat within the ACM/heat exchangers can cause smoke. This smoke is very acrid although I can't say if...
Jump to postless "overwing" refueling taking place. Where does the vapor in the tanks go when the fuel gets pumped in from below? Is there any sort of vapor recovery system? That's a very good question, there is no vapor recovery system (at least not on any aircraft that I've worked on), so I'm guess...
Jump to postHi VC10er, were you referring to the smell of Jet fuel (kerosene), or the smell of the exhaust from the engines that were burning jet fuel at the airport? As Starlionblue pointed out, there's probably less raw fuel fumes around these days for just the reasons he suggested, more careful handling of t...
Jump to postSometimes storage is a good opportunity to take care of maintenance. You very well may be right about them being stored, but they may go back in service when times improve in the airline industry. This is a question you would have more insight into than me, usually for long term storage the windshie...

These could have been removed for inspection of the actuators, replacement of the actuators, replacement of the bearings connecting the actuators to the airframe and the rudder,...
Jump to postI can't think of any advantages, but some disadvantages would be: -Much more reinforcement required in the wing to carry the weight of the engines as well as the thrust produced that far out (heavier wing) -Asymmetric thrust would be greatly amplified in an engine out scenario -More likely to ingest...
Jump to postYou can walk to YXU (London, Ontario), I've never walked it, but I biked there many times when I worked there. The bike ride was 12 minutes for me so I'm guessing an hour walk from some of the houses/apartments closest to the airport.
Jump to postThat would be awesome, if it were that volatile you could put afterburner on just about any jet. Would be quite cool to see a 777 with that option.
Jump to postIndeed, that's why it's sprayed into the combustion can (within the engine) via fuel nozzles or injectors that produce a very fine mist in a very controlled pattern, I've cleaned and changed many of them. Thank you for pointing it out though, I forgot that many people think Jet fuel is a very flamma...
Jump to postI agree that engine oil is flammable but there isn't a huge amount of that available, same with hydraulic fluid really. And once the pumps stop running, very little fluid will continue to flow out. Now fuel, that's another story, unless the reason for the unintended union with the ground is lack of ...
Jump to post"The only thing that can easily exit the aircraft and burn are fuel and hydraulic fluid." Fuel easily burns but hydraulic fluid (LD4 or more commonly known as Skydrol) does not support a flame. If it is sprayed into a very hot fire (such as a torch), it will burn, but when you take away th...

Jump to post"Would be interesting to see who picks these up. If the efficiency is there, maybe we'll see turboprops return to the US3s Regional feed?"
Don't forget that a lot of Americans seem to have an aversion to turboprops.
7500 SHP sounds like overkill for the size of this design. Don't get me wrong, I like power but it also comes at a price, weight of the engine/gearbox and fuel burn. However, you could de rate it and save fuel that way while boosting reliability, but you still have the weight. I read the articles po...
Jump to postPratt already has an engine capable of powering this, the PW150 (Q400 engine - 5071 SHP max) although I'm thinking Embraer would want something newer and more fuel efficient. One disadvantage of the low wing is adequate ground clearance for the prop so most likely a 6 or 8 blade will be used. I'll b...
Jump to postI agree Airbii. I'm an AME and I've read many pilot checklists. They all mention pressurization and it's never very far down the list. Having said this, I always make sure the pressurization is set to "auto" before leaving the cockpit after I finish any engine run, if I was pressurizing or...
Jump to postThe masks in the cockpit are "quick donning" so the pilots can pick them up and put them on at any time for any reason, not just de pressurization. Smoke or other toxic vapors in the cockpit would also require them to put the masks on. The cockpit masks do not drop from anywhere, and they ...

Jump to postYou are correct, the soot would likely be an issue with most pusher arrangements although the P180 (with the Pratt and Whitney PT6A-66) is the only pusher I've ever worked on. As for the oil cooler, that's the way it was made from the beginning. Very difficult to make aftermarket fixes to airplanes,...
Jump to postJust soot from the exhaust (which had to be cleaned with jet fuel). I once removed the prop spinners and they looked like the inside of a stovepipe. All black and full of soot. The oil cooler connections were regular AN fittings, not the loss less ones. I've only ever seen those on hydraulic fitting...
Jump to postI'm not a pilot, nor have I ever even flown in an Avanti. I know of several pilots who flew it and they all loved it, lots of power and fast.

Jump to postAnother point is if the grounding of a fleet occurs because of a failure of a component that is made by a supplier, then it could affect more than one aircraft manufacturer.

Jump to postI can tell you with 100% certainty that the 301 model does have a tail prop, I can't say if it's always used, but I know it's in the cargo hold. The 301 certainly feels more tail heavy/nose light than the 311. When doing a max reverse check on the 301 vs the 311 you feel the nose oleo extend more on...
Jump to postRegarding the PW150 on the Q400, I've motored that thing dozens of times on the starter to generate oil pressure to either unfeather, or feather the prop. There is no need to hold the prop from turning, but it can easily be done by one person if so desired (probably done if there's a ladder or maint...
Jump to postAnother reason for the change was to make the 311 less tail heavy than the 301. The 301 had a "pogo" stick that was attached to the rear fuselage while loading baggage, whereas the 311 has no pogo, or attachment point for it. As for the technical question, while I have never seen it attemp...
