If you were in a harrier jump jet,and hovered for one hour at over 500ft would the earth move below you?
Answers:
In reality, the Harrier can only hover for 90 seconds. The Rolls Royce Pegasus turbofan engine overheats, so a water tank is on the aircraft to cool it down. This runs out after 90 seconds, however.
If you were to get in a magical harrier that could hover indefinitely, then no, as you're in the atmosphere, and under the Earth's gravitational effect, which would keep you over the same spot.
absolutely!!
The harrier engine overheats while it is in the hover. To counteract this, cooling water is sprayed into the engine. The harrier only carries enough cooling water for a total hover time of 90 seconds, interestingly enough.
But ignoring that, yes I'm sure the earth would move!!
your engine would probably overheat and you would crash.
No because the air moves with the earth
Of course not :-(
yes if a gps or no ground landmarks are not being used
The earth rotates at 1000 mph at the equatorIf you hover in the same place, the ground below you will rotate.
With the F-35, It can dover without the heating problem.
aye you would meet yr self on the way back
No, because you hover in a geostationery position, however wind movement would cause some drifting.
It depends on what you are using for hover references. It you are doing it by sun/star sighting, then yes, but you wouldn't be hovering then.
No! You need to consider Newton's third law of motion - For every action there is an equal and opposite reaction. At 500 feet there would be no ground effect, and the entire action-reaction equation is absorbed in the air.
Even at ground effect, the mass of the aircraft is held airborne by the movement of air/exhaust through the negine nozzles, so no effect on the earth. No different than a helicopter hovering or a 747 taking off from a runway. The mass of the earth includes the earth itself, the atmosphere, heavier than air and lighter than air aircraft, and a few satellites in orbit. The fact that a plane is in flight in the atmosphere does not change the position of the earth relative to its orbit around the sun, as there is no change in the mass, velocity, or moment of the earth.
By the way, I have not flown Harriers, but I dare say that it would be out of fuel long before an hour was up!
Incongru is 100% correct. You only get 90 seconds of verticle flight before your run out of water..
Aircraft move through the air, but relative to the ground, so actually the answer is no.
only if you matched the velocity of the earth also, if you pointed the nose of the aircraft west. it is theoretically possible. the only problem is that you are hovering out of ground effect, (HOGE) around 10ft, which means you will not get the benefits of the ground cushion under the aircraft hence you will use more power therefore more fuel, a harrier will use two thirds of its fuel for a vertical takeoff, so this whole theory into practise thing would be a non starter..

No. You are hovering over one spot on the earth. You are remaining stationary relative to the earth. Therefore you stay with the earth even though it is rotating around its axis.
If you said you were hovering in the same spot relative to space, the earth would, in theory, rotate from underneath you. You would however have to lose your own relative velocity which is the same as the earth's.
Harrier needs almost full thrust to hover so cannot lift enough fuel to hover for an hour, does your brain have an engagd mode?
