Aeroplane question?

Airplanes don't climb to avoid mountains.

The higher an aircraft climbs, the lesser the wind resistance becomes since air is thinner as you go up. Thus the aircraft can speed up while using less fuel.

Also fast moving rivers of air called 'jet streams' help the aircraft swim along and save some fuel.

The higher altitudes also make the journey less bumpy since most cloud formations occur below the 30000 feet mark.

aeroplane?

Em honestly when aircraft is at 40000 feet it can have the max cruise speed which does not consume fuel much. This what pilot
prefer. This is due to the density of the air. The higher altitude the low the density. So you can travel fast then low altitude. If you scared of the aircraft collide with the mountain it is impossible with nowdays aircraft technology. Equip with GPS and other system that makes safe flight. So pilot can navigate easily and safely. Hope you understand. Don't get wrong. Thanks.

You spelled airplane wrong. Now my answer; airplanes fly at feel at the high and around 40,000 to keep airspace clear of for planes to travel.

its actually saves fuel. the more high the plane fly the less fuel its consume

Fuel Efficiency is a reason why planes travel at those heights.
Safety is another reason..

We can go on .. there is more than one reason why planes cruise at high altitudes

the higher the plane fly, the most efficient the use of fuel... why? because air at the higher altitude is more less density compare to the lower air.. this make the flight can fly smooth and less resistant... and that why the cabin need to be equally pressure in outside and inside if cabin...

Planes fly high, not only to awoid mountain, The higher it flies , gravitational force is less and fuel consumption decreases,2) To avoid other planes on the same sector by keeping a distance of 6000ft.

The higher they go, the better fuel milage they get. They also can grab a good tailwind up there.

because the air is thinner and there is less drag on the aircraft and also because they use less fuel at this altitude. plus its pretty cool

Because there is what you call 'air space' .....which includes restricted zones that are reserved only for the military use. If a plane was to find it's way in restricted military air space it could be shot down. That's why they have to fly at that altitude within the commercial air space.

Flying this high is not just to clear mountains.
It is aerodynamics that determine the height
of flying. The air is thinner, less drag, and a
jet stream to help move the plane faster.

the higher up you go...the faster the plane can travel (less dense air)...so it actually wastes less fuel......a 747 only needs to go 100 mph to lift off...it's amazing "lift' is a mufugga!!

they stay high to fly above most weather conditions..and they vary between 30000 - 40000 so as to have room to pass other air traffic
