The "drone" like any other mass (weight) will maintain its speed and heading/ direction unless there is a force acting on it.
Since the gas/ air in the plane is also traveling at the same speed as the plane itself (gasses have mass) the air resistance will be about the same as "on the ground" / flying indoors.
So IF the plane flies at a EXACT CONSTANT SPEED AND HEADING the "Drone" will behave just as it would flying indoors.
ANY VARIATION of the speed and heading and the "drone" will move to the opposite direction (plane goes down, drone goes up relative to the plane)
This is because there is not the same force acting on the drone/mass as there is on the plane that caused the change in speed/direction.

In practice since its very unlikely a plane flies at a exact constant speed / heading the "drone" will move around in the cabin indicating those deviations in the speed / heading.



On a other note ; flying a drone near a airliner (inside is as close as you can get..) can cause mass hysteria and airport shutdowns.

Airliners in flight are not pressurized to sea level air pressure.
Apparently the pressure is as you where at 8000 feet.
So the performance of the drone is the same as it would be flying at this air pressure/ altitude .
Unless the drone is able to fly at 2438 meters high it will not be able to maintain altitude.

Likely its under powered or has the wrong props so any attempt to fly would result in it falling to the floor or just not take off.

So you are saying the drone will slam into the back of the plane?

If you know the weight of the drone in kg and you know how much trust (force) the motor/ prop combination gives then you can calculate how much the drone can accelerate/ slow down.

Slowing down takes the same amount of force as going faster just the other way.

This assumes a vacuum so the actual performance will be a bit less because of air resistance.

So IF the change in speed is below of the drone maximum acceleration (or slowing down.. same thing then you should be able to compensate.
If not it will slam in the floor/ wall ceiling with the speed of the change minus the amount of speed it tried to compensate with..

The speed of impact depends on the distance between where the drone was since that dictates the time it takes to reach the point of impact.

When you jump up in the air inside your 747 do you slam into the back wall?

If you try during takeoff then yes if the acceleration of the plane exceeds the drone performance then yes.
During climbing (at constant speed) it would hit the floor ;
During landing (speed brakes deployed for example) it would move towards the front of the plane.

What would be a great clip is when the plane would do a perfect axial roll at constant speed.
The drone would appear to be rolling inside (relative to the plane) while in fact it isn't (absolute to earth)

If the plane increases speed while you are "airborne" then yes you will move back ; if the plane is at constant speed then your position relative to the plane remains the same.
Same as a ball on the floor of your car moves around while you are driving.

That is all there is to it.
Do they teach that In American schools?

Have a look at this; the plane climbs and dives in such a way it cancels out gravity.
To do that it has to pull out of the dive and during that part of the flight the people/mass inside experience several times the force of gravity.

Flying a drone during during those conditions would be interesting (anyone have contacts at NASA?

I got to be weightless for 7.5 minutes (6 min 12 sec)

I volunteer! I’ve always wanted to ride in that plane.

How to get motion-sickness

Think about if the drone was tied to a string hanging from the ceiling of the plane instead of flying. What would it do during the acceleration of takeoff? Swing backwards!

Rent a truck with a big trailer and fly inside while its driving/ turning / braking .
You only miss the vertical force part but the principle is the same.

Or just a big U-Haul
