Before it hits the ground
If you leave your gear down on take-off, you will not need to use the emergency gear release on landing...
Airplane windows need to be open during takeoff and landing to allow passengers to see outside and help maintain orientation in case of an emergency evacuation.
Need to replace Wheel Bearings
Window shades on an airplane need to be up during landing for safety reasons. This allows passengers and crew to see outside in case of an emergency, such as a fire or evacuation. It also helps the crew assess the conditions outside the aircraft during landing.
Yes. The aircraft is designed with a Maximum Takeoff Gross Weight and a Minimum Landing Weight. Therefore, if a large airliner has an emergency and must return to the airport, such as one engine quites, then they have to dump fuel before they can SAFELY land. Some aircraft have to circle the airport to burn off fuel. However, sometimes this is done in order to give the flight crew time to solve the problem. This is usually true if they have a landing gear problem and want to try to get the gear to come down. Yes and no. As the foregoing answer points out, manufacturers have maximum landing weight specifications for their aircraft, and under normal and most emergency situations, the flight crews need to reduce the aircraft weight so as not to exceed these weights. On the other hand, some situations require getting the aircraft on the ground as soon as possible, and in these cases, any airplane can be landed at any weight...assuming there is enough runway. In these cases, a report of the overweight landing must be made and "overweight landing inspections" must be completed prior to flying the airplane again.
Theoretically, an airplane does not need to have any magnets in it, but most airplanes do contain magnets. Every electrical motor contains magnets, and small electric motors are used in various parts of an airplane, such as for raising and lowering the landing gear.
It could but the pilots need to land well otherwise there plane might topple over and crash.
An astronaut landing on Mars would require a spacecraft to enter the Martian atmosphere, slow down through a combination of aerodynamic drag and parachutes, and use retro-rockets for a controlled descent to the surface. The spacecraft would need to deploy landing gear to touch down safely on the Martian terrain.
Airplane flaps are used during takeoff and landing to increase lift and drag, which helps the plane to reduce speed for landing and take off. At cruising speeds, the airplane is already flying efficiently and has no need for the extra lift and drag provided by the flaps.
They're bolt-on components. You'll need an impact wrench, and a torque wrench to ensure that you torqued the bolts properly (which is very important, given the function of the landing gear).
A plane with floats is a "floatplane" or a "seaplane." A plane with skis is a "skiplane." Check it out: you need a special license to fly a seaplane! If you have a single-engine Piper and land it at airports, the minimum license is ASEL--airplane, single engine, land. You could also fly it with an AMEL--airplane, multiengine, land. But to fly a seaplane you need an ASES or AMES--airplane, single engine, sea or airplane, multiengine, sea.
It makes easy to reach to first gear blindly pushing the gear downwards when slowing down and stopping. Hence can further pick up from first gear.Bikes can start in any gear hence no need for bike to be in neutral gear.
