Technically anyone could get in and start a big jet aircraft, but it would have to be pointing in the right direction. Getting a large transport jet going is allot more complicated than just starting the engines. The whole aircraft has a multitude of systems that have to be brought on line even before the start is selected. Failure to do so would have the computers on board sulk until you said good morning to them. The first operation, thus, is to 'power-up' the aircraft, this means to establish electrical power. This can be done in two ways, one being establishing a ground power unit and secondly, the aircraft's own auxiliary power unit, which is normally a little jet engine in the tail of the aircraft. The APU as it's called (auxiliary power unit) will also supply air pressure for cabin air conditioning and to the air starter units used to spin the main engine turbines at high speed to start the main engines, when commanded to do so. This is why the air-conditioning temporarily goes off when the engines are starting, because the APU cannot supply both engine start air and conditioning air at the same time.
After electrical power has been established, the on-board computers will come to life. Some computers are in their own little world and control things that are fully automatic, you only hear from them if they detect a defect in their own self test. Other computers are in pairs and threes, they monitor each other and alert the pilots and engineers via other computers if any detects faults in the others. There are two or three inertial navigation systems that are driven by lazar light. In each unit there are at least three lazars in different orientation. These units can detect the slightest movement and calculate the position of the aircraft by adding that movement to the aircraft's current position. The IRS units are very - very clever since they measure the movement by measuring the shift in the light spectrum when the aircraft moves. Since they measure movement, they have to know the speed the world spins at and the speed of the earth through space, to deduct that from the small movement on the aircraft in order to calculate the position. Allowing the IRS units to come on line is essential and must be done before main engine start. The aircraft must be completely stationary for this to happen.
After all that has been done the main navigation computers are programed for the route to be flown and with other information. The Flight management computers (as they are called on some aircraft) can also acquire their own information, like how much fuel is on board, and in flight the airspeed of the aircraft the angle at which the aircraft is at and from that it will calculate the weight of the aircraft.
So when all the systems are up and running and the computers have done their thing and have been programmed where required we can carry out all the other checks, switch on the galley power and call for a cup of tea and when we have drunk that we are nearly ready to start the main engines.
When ready to start the main engines the air system has to be re-configured to enable the starters to operate, following that the normal procedure is to place the engine start switch in the auto start position, where all the starting functions are carried out automatically. Both pilots monitor the engine start as sometimes things can go wrong like a hung start or a hot start. These sort of malfunctions can seriously damage a multi-multi million dollar engine in a flash and no pilot would want to be responsible for that. As the engine spins up to speed, at a predetermined percentage RPM the captain will select the fuel switch to the run position which will allow the fuel to be injected into the engine for light-up. Following a normal start the air system is then reconfigured once more as part of the after start check list, along with other post start items.
All in all what I'm trying to say is that it is a complicated procedure and not just about turning a key like a car. So if you were to board a dead aircraft on the tarmac and turn the start switch nothing would happen.
So what if the engineer wanted to run an engine for an engine test, would he have to follow the same procedure? Well, apart from loading the flight data into the flight computer, he would have to do everything else, if only to prevent all sorts of warnings that would occur trying to short cut the procedure, since the only warnings he would wish to see is anything that is relevant to the engine start, otherwise engine starting and running warnings may well be disguised by other more insignificant malfunctions. Hope this has been helpful.

I recently browsed a forum where this was debated by the FE believers vs normal OE people. (Obloid Earth).
The FE'ers simply believe that photos, videos etc are hoaxes. :))

I can speak confidently but not authoritatively on this, so let's consider this answer tentative. I would be glad to be corrected.

Military gliders were replaced by helicopters after World War II, and no one seems to have found a civilian use for large ones. Unpowered flight is a sport, now, so there don't seem to be any with more than 2 seats. The only recent exception I can think of is the Space Shuttle, which was unpowered during its return from orbit.

Since they allow some large well known airlines special call signs like "Cactus" then they allow them special numerics as well.

You will just have to get checked out on any aircraft that you want to fly, with a flight instructor.

Getting your aircraft pilot's license takes work (and money), but it is well within the reach of anyone of normal intelligence and physical ability. I've known college students who basically collected pop bottles for the deposit, and picked up part time work on weekends, and managed to get an hour or two of training every month or so. Took them a couple of years to get their license, but they managed it.

For a normal category license, you are looking at about 40 to 60 hours of flight training (actual time in the plane). Not all of that requires an instructor. Once you "solo," you will be allowed to fly by yourself (with the instructor's approval). Often the training aircraft will be older and very basic planes - but that's just fine. It's the basics that you are learning.

It takes lots of practice, and there is a lot of book learning (weather, regulations, principles of flight) as well. But you can do it if you want to. Most things that are really valuable take work.

Are you asking about the certification of the aircraft itself (14 CFR part 3 vs. 14 CFR part 23?), or approval for instrument precision landings (ILS CAT III)? If the latter, it's really not an aircraft issue, but rather an equipment issue. That means you can have two aircraft of the same type, but one is equipped for CAT III and the other is not.

CAT III is basically autoland, which means it needs redundant navigation equipment, computer throttle controls, etc. But you could, in theory, outfit an old Citation with all that and get it approved (at some huge price <G>). And, don't forget, the crew needs to be certified as well.

Pilot can do anything he judges best for his flight.

Aircrafts | Answered on Jan 29, 2018

Yes but the heat will be dryer. Its a lower water content.

Aircrafts | Answered on Jan 29, 2018

Its easier to control the airplane with that balance, a twin like that would be easier than a single for the same reason that the prop rotation makes the plane easier to turn to one side than the other.

Wings provide lift with enough speed against the air mass.

Changes in terrain and weather, planning assent/descent, and for balloons seeking the desired wind direction to get somewhere.

Aircrafts | Answered on Jan 29, 2018

Depends on aircraft and altitude.

Aircrafts | Answered on Jan 29, 2018

Its a business deal. You could contract for a fixed minimum period of time.

Aircrafts | Answered on Jan 29, 2018

That would be the ground prox system on the aircraft it lets the flight crew know how far they are above the ground during an approach to the landing runway.
