It’s a neat little area to “hang out” in lol. Haha..The ATR Aft cargo compartment can also be a good area to hang out depending on the situation.. It is also noteworthy that carrying DGs is prohibited on the Pax ATR Cargo compartment as although physically separated, they fall in same level and onl...Jump to post

The answer to this is it depends upon the specific aircraft model and which surfaces. The 744 flaps, as referenced in the OP would be a great start. Flaps generally are position specific ie. have discrete outputs per the Flap lever Position in the Flight deck. Primary control surfaces like the Aile...Jump to post
A couple of tragedies occurred when all hydraulic fluid was lost. Japan Air 747 and United DC-10. Do all commercial types use hydraulic fuses or just some? What other systems are there to prevent the complete loss of hydraulic fluid after a catastrophic failure? Every Hydraulic system on an Aircraf...Jump to post
Does an A320 With V2500 idle at a different speed with just the left engine running (single engine taxi)? Earlier procedure on A320 was to start Engine 2 first as it is directly connected to Yellow EDP which supplies the Parking Brake pressure. Now the procedure has been revised to simplify procedu...Jump to post
Stranger still was the Lockheed Constellation, which as well as having a forward angled nose gear, had considerable 'camber' on the nose wheel axles - meaning that the wheels were angled so that the bottoms of the tires where closer together than the tops. Perhaps this was to counteract to some ext...Jump to post
Problem with the canted nose gear design is it completely lifts the outboard nose wheel off the ground in a tight turn while taxiing, now you’re steering with just one wheel, not so good, especially when you have a wet surface Correct. Tight turns mostly are done at lower speeds. A320 Family can al...Jump to post
Adding to above replies Volcanic ash is also very abrasive which resulted in a flame out of engine long back. Forest smoke may be chemically toxic in the long run but a few seconds of ingestion is pretty okay for the engine. The Aircrafts may be shutting off the bleed when they fly over a smoke clou...Jump to post
Can I ask a dumb question? I've never seen an air conditioning hose that didn't have a fold or kink in it. Are they not actually *designed* to be that way? Actually they do. You just cant notice it when it is supplying High Volume Air as it becomes inflated. However old hoses do leak from areas whe...Jump to post

Engine manufacturers sometimes test their engines by replacing one of the regular engines on a quad. That's strictly for test purposes only, though. 0744433 Nice center gear, there...

Some cargo doors are outward opening plug type. The aft small cargo door (70") on the B777 for example is an outward opening plug type door (and I'm pretty sure it's the same on the B767). The forward large cargo door (106") and aft large cargo door (106", if installed) are non-plug ...Jump to post
What about the outer wing tanks? Do the post-2014 A319/A320 and A319neo/A320neo aircraft also have a single wing tank like the A321s? Single wing tank like the 321 would have been great. The 321 wing has a slightly thicker skin crossection and construction hence it could get away with No Outer Tank...Jump to post
I would think that, while your idea might sound interesting, there are likely the following drawbacks: - Aircraft compatibility. Traditional tug need to connect to different aircraft by the means of different bars. Some exotic aircraft even need to carry their own tow bar in order to get pushed. - ...Jump to post

What about IAE V2500?
I remember when AA used TRs for “pullback” on the MD80s at DFW. The sequence would start with a momentary forward motion, then you’d hear the TRs engage before starting your pullback. Except for the slight forward motion, it was pretty cool. It was called Powerback. Saved a few minutes of time but ...Jump to post

Can all aircraft have a tow bar connected from the rear?
The turquoise color is inherent in the CTi formulation so... yes, these will be in the production engines and no, multiple colors would not be an option, nor is this for marketing purposes. You can see a similar color on the inner liner of the PW1100g engine. This is functional and a result of the ...Jump to post
Slightly off topic, the A320 with IAE engines have a slightly less Wing Tank capacity than the CFM counterparts due to the incorportaion of a Dry Bay inside the the Wing cell around the pylon area for additional safety. This can be a reason, however just a wild guess.Jump to post
Every new aircraft I have seen delivered from Airbus and Embraer comes with a cover kit for engines, pitots, apu exhaust, plugs for some air inlets, etc. Some airlines keep them on the aircraft, others remove them and store them in the line operations. These official covers are not necessarily requ...Jump to post

I know it is too early to speculate, but watching the video it seems the Towing speed was high followed by a sudden braking by the Tug causing tow bar failure. Will have to wait for the official report to be out.Jump to post
Same incident happened on an A320 a couple of years ago, where the nose wheel liberated after Aircraft rotation. Investigation revealed the Final Torque was given after the lowering the axle jack, resulting in inadequate final torque and loosening of the axle nut.Jump to post

My observation on the A320 with Radial tyres: Have seen retreading not more than 5 times on a single tyre. Usually denoted by R1,R2 as such. And the Vendor carries out Shearography Inspection to make sure a tire is fit for a re-tread. Ive heard you can do more number of Retreads on a bias but the li...Jump to post
The downside is that while the turbomachinery in all four engines will be identical, two engines will require additional gearbox components, a larger oil system and a mirror-image propeller design, increasing support costs. ] Counter rotating props on the same axis are for reducing the counter torq...Jump to post
