Common sub-sonic passenger aircraft can only get to a ceiling (this is not their maximum height) height of 43,000 feet, they can go higher, but that is the comfortable cruising altitude. Space Craft under the Aerospace engineering concept can go as high as they wish, and there is Military Super-Sonic air craft, their ceiling is anything from 30,000 to 60,000 feet.
As aircraft go higher the air becomes thinner reducing the energy required to push the aircraft forward
An altimeter (altitude meter) tells the pilots how high the aircraft is flying. There are 2 types of altimeters commonly used in aircraft: pressure altimeters and radar altimeters.
The higher an aircraft is the less air in the atmosphere. this means less air resistance which means you can go faster with less effort. also less air means less fuel burnt for same power. this saves fuel. for this reason most aircraft will operate at high altitudesThere are also fewer obstructions at high altitude than there are at 1000 feet.
the elevator is what makes the the aircraft go up or down.
The SR 71 was a very secret high speed, high altitude reconnaisance aircraft. Only 32 were built, at enormous cost.
244 feet tall
consider an aircraft wings are to move the high speed,it will make a pressure difference in upper & lower surface of the wing so the aircraft are flying
about 42k ft
depends on the aircraft.
Since aircraft do not, and in fact cannot, go into space then it should be obvious that no aircraft has ever been to Mercury, as yet.
Aircraft can go up to about 1,600 mph .
A straight wing is good for a low-powered, slow moving aircraft. A straight, thick wing is good for short takeoff and landing aircraft, and high-speed, high-thrust aircraft need a swept wing.
