Engines power the aircraft forward so the wings gain lift to raise the aircraft into the air.
Nothing, an Aeroplane require air flowing across the Airfoil Wing to create lift, as there is no air on the moon, there could be no flight. Almost everything about conventional Aeroplanes require air to function. Propeller driven aircraft require air for their engines and the propeller itself could provide no thrust with out to push against. Jet Engines also require air for the combustion process. Though Rocket Engine Aeroplanes would ignite and provide thrust, without air for the wings, they would simply be really fast ground vehicles.
Aeroplanes DO cast shadows on earth, I have seen many. They are usually easier to see from the air.
heat
it can rise because of the helium and the gases help make it rise to the sky
because the cost for the product is greater then the cost for the steel also it is light and when it is in the air it is denser then the clouds
jet engines require air, compression, and combustion to make it work
air space through which aeroplanes are bound by Civil or Military rule, to fly
Many things move in air, from dust, leaves off trees, to aeroplanes.
Sort of. Some planes can reverse the thrust of their engines. Propeller aircraft can change the pitch of their propellers so it can "bit" more air. Some can be reverses in pitch so that it is provide zero thrust.
Aeroplanes (Air-crafts) for commercial and military purpose: Yes Bangladesh has many Aircrafts on both the sectors. All the aeroplanes are imported. Bangladesh on its own can't build or assemble aircrafts. No such facilities.
it depends if the aeroplane is in an airport on in the air
To make air lighter you would increase the heat inside the balloon, making it less dense, causing it to rise.
