Is there a video on youtube I couldn't find anything on Youtube unfortunately. And what do you mean "remove material if need be." As others have noted, the abradable liner is made of a material that is softer than the fan blades. Thus, if the blade tip should contact the abradable liner d...
Jump to postI know fan blades have a very minimal clearance from the engine cowling, but can it ever rub against the cowling interior during turbulence or anything? And if it could rub against the cowling, what would happen? Yes they can. The fan casing is made with an abradable liner such that the tips of the...
Jump to postThe DC10, MD11 and A320 series aircraft do have the forward tilted NLG gear. It is called Caster Angle. Exactly, this geometry being similar to the rake and trail of bike steering. On the B747, A330 / A340 for instance, the nose gear leg is straight up and down. 1507521 Self centering in this case ...

Jump to postThat's why the kosher method of pressing anything while following the QRH or ECAM is to name the panel first and be very methodical. For example to turn on Crossfeed 1 on the 340, you'd read "Crossfeed one, on" from QRH or ECAM, then point at the panel with the big letters FUEL on the sid...
Jump to postTo expand, on Airbus the logic is thus. I wonder if it was always this way? For some reason, I have recollection of an incident involving an A340 (SQ?) where the pilot inadvertently shutoff all four hydraulic systems in-flight instead of manipulating four, fuel cross-feed valves. Part of the reason...
Jump to postThanks for the feedback. So I am wondering if the A350 EDP can be disconnected from the engine gearbox same as the IDG or the CSD. From the looks of the following, I'd say not; http://www.smartcockpit.com/docs/takeoff_full-cockpit.pdf The disconnect push buttons for the IDG's are clearly visible an...
Jump to postThen again, if you want to nitpick there are non-moving AoA sensors out there.) The B2 bomber has such a system. If I understand it correctly, there are 24 PTU's (Port Transducer Units) that provide attitude (side-slip and pitch), altitude and airspeed data. http://www.glennpew.com/Special/B2Facts....

Got a response from the devs, there was a cap of 50 albums. A change has been implemented and will roll out in the next small update.
In the sharper pictures of the engine front, we see an asymmetrical part in the center. To my uneducated eye this looks like a break due to crack propagating. What part is this? http://home.clear.net.nz/pages/ccreegan/images/sprite%207.png It looks like the conical drive arm part of the fan disk. h...

You have 56 albums as far as I can see, do you have an example of a missing album or two that I can forward to devs? Hi JohnKrist, Thanks for the reply. I just checked my albums on my profile page and it appears that they are all there (56 in total). Thus, the albums are "missing" from th...
Jump to postDear Mods,
Apologies if this topic has been discussed prior. I did do a search with no results.
I have noticed that a number of my photo albums have disappeared. Is there anyway that they may be recovered?
Thanks for your assistance with this matter!

The stab tank on the 747 is just a 'dumb' fuel tank. It is filled if the total fuel required is in excess of a certain value (according to a fuel distribution logic between the 8 tanks) and is used almost immediately during the cruise (it empties into the center tank if memory serves). As far as th...
Jump to postThat was as much a part of he system as the extra 13,000 lbs of fuel. Even if you did not need the fuel for the trip, it would pump fuel aft when you climbed through 19,870', or some weird number like that. The purpose was to move the CG aft for less drag. Interesting. Definitely sounds like an act...
Jump to postThe reference to "trim tanks" might be a carry over from the MD11 fuel tanks in the horizontal stab? Could be. I think the term "trim tank" is strictly applicable to the A330 / A340 only as the fuel in the stab tank is used to actively trim the aircraft, whereas I seem to recall...
Jump to postBravoOne wrote:Surge tanks are usually at the end of the wings?
Well using actual weight would be a nightmare -- you weigh the plane and know it weighs a certain amount but it would be a complete guess as to where that weight is distributed on board. Assuming that a weighing system measured the weight of the entire aircraft with fuel, passengers and cargo, sure...
Jump to postI'm pretty sure the 380 has no center tank, at least in the current version. But if it did, that would always be emptied first. Typically you'd empty from inboard and out, but with quads it becomes a bit more complex. I think the 380 has four tanks per wing plus the trim tank. Looking at this diagr...
