| Top new questions this week: | 
| What would happen? Would the cabin pressure increase too much and cause damage? | 
| Was this because of the drooping nose preventing it from being placed anywhere further up? | 
| So, back in the day a lot of carriers had a “bridle” fitted onto the catapult. This was basically a V-shaped cable that attached to two points on the underside of a plane and would basically … | 
| How do the RPMs stay constant in a gas turbine engine? For example in car with piston engine, when you keep pressing the accelerator the rpms keep picking up, to keep the rpms constant you must let … | 
| This may be a dumb question, but can ATC reject or amend your flight plan to prevent a GA training aircraft from flying into a busy airport (i.e. Atlanta)?  As an example, flying VFR near Nashville, … | 
| I was reading this question and trying to think of ways to park an aircraft tail-to-terminal without using reverse thrust, and this question popped into my head:  Are there any aircraft that could, … | 
| I watched lots of video related to sucking process of a fan in a turbofan engine, but I’m confused at a point.                                    In this link and many videos like this, I found the fan’… |

| “An aircraft is cruising at FL170. The altitude shown with QNH set is 17,500 feet. The OAT is -10 deg C. What is the true altitude?”    The ISA temperature deviation is 9°C.    My calculation is:    17,500′  … | 
| The terms apron, ramp, tarmac, taxiway, parking area, gate, hardstand are used in a way that I cannot understand.  Boeing Everett Factory. Photo by Andrew Hunt at Airliners.net (url unknown). Cropped … | 
| Why are quadcopters not flown by human pilots yet?    Wouldn’t they be more stable and easier to control than helicopters? | 
| Why does an airplane need trim, and what does it do during the flight? Does an autopilot adjust the trim automatically? | 
| I was having a discussion with some friends about general aviation aircraft with cabin-class seating. We were discussing cruise speeds and there were some “shop talk opinions” flying around about what … | 
| I’m told that this is true, but I can’t imagine why.  It seems like the fact that there is less air would make the engines less efficient…  But that probably just shows how little I know about jet … | 
|   Can you answer these questions?								 | 
| I flew a motorglider with a electric CS prop which takes 90 seconds to fully feather. Contrast that to a hydraulic governed prop, which takes just a few seconds to go from one extreme to the other. … | 
| If a pilot has basic currency to carry passengers in an aircraft requiring a type rating, say a Boeing 737, does that mean the pilot is also current in an aircraft in the same category and class (AMEL)… |
