Given that 3D-printing is becoming more and more important, would it be possible to make the parts where tooling has now been scrapped that way, using composites for example (still likely requiring re-certification)?Jump to post
IIRC, the flaps and L/E devices are driven by the center hydraulic system. That system has two ACMPs (alternating current motor pumps) that operate on demand. The L & R systems have an EDP and elec pump to supplement the EDPs during high demand operations. The hydraulic system operates at 5000p...Jump to post
No, I wasn't talking about the flap sound. I was referring to the "spooling up" sound and continuous humming in the background. I was just trying to give an example of what I understood OP was talking about. Thanks for your reply though! But the flap PCU is the sound (I would even call it...Jump to post
Are you talking about the sound heard in the video below from 3:30-3:35 onwards, also heard during take off and final approach? If that is the sound in question it is obviously the hydraulic motor operating the flaps, as you can see them moving in the video. That sound will be heard again anytime t...Jump to post

You might love it, but airlines don't. Wide bodies always have a higher fuel burn than narrow bodies, so if possible they always prefer narrow bodies. If you take two planes with similar seating capacity, where one is a wide body and the other is a narrow body, the narrow body is always the preferr...Jump to post
Length roughly: A310 47 m, A 300 54 m, A330-300 59 m I assume Airbus would have preferred an A330-200 and a shrink if a good, weaker engine had to be available. A shrink to A310 length is probably overdoing it. So yes, a 170-190 t MTOW plane with A330 fuselage, 51 m carbon wing and new engines is a...Jump to post
Basically, the aircraft calculates expected airspeed, AoA, etc. from GPS and INS data and compares it to the results from the two static vanes.

Sounds wrong. If you think about it, your statement is, by definition, nonsensical. And who do you think enforces international law?

I would disagree with you, a lot of your issues seem to arise from cultural differences.

You seem upset, if it were up to me the USA would leave NATO and Europe completely. Yes, Western European governments are inept, condescending, ungrateful and entitled. You think 100s of casualties in a war in Afghanistan is anything close to what the USA has given to Europe? The free and peaceful ...Jump to post
Well... This discussion went off the rails.... To get it back on topic, I think that Kelly, much like other CEOs, are knocking on the government's door for financial guarantees and bailouts (Kelly is asking for more support in the interview). Which I think should be granted in one form or the other.Jump to post
I , and I suspect many others won't bother going to the movies, travel for leisure, and many many other activities that require a mask.

I am a little more optimistic than Southwest CEO Kelly. As soon as a vaccine is readily available to the general population people will want to resume to normal life. With sufficient government spending, ordinary people will have enough money to get the economy going again. Give it a year or two and...Jump to post

The English Wikipedia page on the Typhoon states that the aerodynamic modification kit studied around 2014 (Improved handling with high weapon loads and higher manoeuvrability) would be part of the German order for the new Typhoons we’re discussing here.

Just out of curiosity a scenario I was thinking of. Going to war in a, for Germany, realistic setting like Afghanistan. Now you have Growlers, Super Hornets and Typhoons available.

This article (in German only) states that a preliminary decision has been made to replace the Tornado with up to 90 Typhoons and 45 F-18 from 2025 onward .

Thanks for the detailed response. If the RCAF had access to all the data necessary, it should be a pretty straightforward process choosing their aircraft.

Given that Canada is looking for 88 jets would there be value in having two subfleets, say 40 F35 and 48 Gripen (or say 40 F35 48 SH, just making something up here)?

Some sparking from the brakes is normal for the old Dash 8's, or any other aircraft that has metallic brakes. Also you are mistaken, the bottom part of the MLG of the Dash 8 you were on did not touch the runway on landing. The MLG axle is at the bottom of the gear strut, therefore if the strut has ...Jump to post
Funny enough, two or three years ago I was on an Air Canada Express flight on a DC8-100 and we had a few sparks on take off, too, without losing the wheel though. Upon landing, more sparks. The Shocks seemed to be worn out, as well, since the bottom part of the MLG scraped the runway upon touchdown....Jump to post

I’d prefer the 777 over the 747-400 mainly cause most cabins on the -400s still flying seem a bit dated (huge fan of mood lighting). I’d love to try the 747-8 though. As cool as the GE90 is it’s also not as quiet as the 4x CF6 on the 747. In that regard BA’s RR-powered 777s are greatJump to post
Why did Air Transit keep its A310's so long? I mean, it is not the most fuel efficient aircraft that's available. :) My guess would be that the aircraft were paid for/leases were cheap, their range allowed them to go trans-atlantic, but the aircraft was small enough to be filled up on thinner route...Jump to post
Looks like it has been used, for example in aircraft breaks, insulation, etc, mostly on frames built before the 1980s. Seems like there are special maintenance routines in that case.
