a communications interface that obtains boundary information associated with a three-dimensional (3D) flying space, including a boundary of the 3D flying space, wherein the 3D flying space is defined by a cross section about a center path;

a processor that continuously determines a distance between the boundary of the 3D flying space and a location of an aircraft; and

a user interface that presents feedback in proportion to the determined distance between the boundary of the 3D flying space and the location of the aircraft, wherein the feedback includes at least one of resistance or force that increases in proportion to decreasing distance between the boundary of the 3D flying space and the location of the aircraft.

2. The system recited in claim 1 , wherein the cross section defining the 3D flying space is one or more of the following: a circle, an ellipse, or a rectangle.

3. The system recited in claim 1 , wherein the user interface includes one or more of the following: a virtual reality headset, a touchscreen display, or a display integrated into the aircraft.

4. The system recited in claim 1 , wherein the user interface presents a speed limit associated with the 3D flying space.

5. The system recited in claim 1 , wherein the user interface presents a permitted direction of flight associated with the 3D flying space.

6. The system recited in claim 1 , wherein the user interface outputs, via a speaker, the distance between the boundary of the 3D flying space and the location of the aircraft.

7. The system recited in claim 1 , wherein the user interface, in response to the distance between the boundary of the 3D flying space and the location of the aircraft not exceeding a threshold, outputs, via a speaker, a correction direction which would cause the distance between the boundary of the 3D flying space and the location of the aircraft to increase.

8. The system recited in claim 1 , wherein the user interface, in response to the distance between the boundary of the 3D flying space and the location of the aircraft not exceeding a threshold, increases an amount of force feedback output by a force feedback input device.

9. The system recited in claim 1 , wherein the user interface presents a representation of the aircraft showing the location of the aircraft relative to the 3D flying space.

10. A method, comprising:

obtaining boundary information associated with a three-dimensional (3D) flying space, including a boundary of the 3D flying space, wherein the 3D flying space is defined by a cross section about a center path;

continuously determining a distance between the boundary of the 3D flying space and a location of an aircraft; and

presenting, in a user interface, feedback in proportion to the determined distance between the boundary of the 3D flying space and the location of the aircraft, wherein the feedback includes at least one of resistance or force that increases in proportion to decreasing distance between the boundary of the 3D flying space and the location of the aircraft.

11. The method recited in claim 10 , wherein the cross section defining the 3D flying space is one or more of the following: a circle, an ellipse, or a rectangle.

12. The method recited in claim 10 , wherein the user interface includes one or more of the following: a virtual reality headset, a touchscreen display, or a display integrated into the aircraft.

13. The method recited in claim 10 , further comprising presenting, in the user interface, a speed limit associated with the 3D flying space.

14. The method recited in claim 10 , further comprising presenting, in the user interface, a permitted direction of flight associated with the 3D flying space.

15. The method recited in claim 10 , further comprising announcing, via a speaker, the distance between the boundary of the 3D flying space and the location of the aircraft.

16. The method recited in claim 10 , further comprising suggesting, via a speaker, a correction direction which would cause the distance between the boundary of the 3D flying space and the location of the aircraft to increase in response to the distance between the boundary of the 3D flying space and the location of the aircraft not exceeding a threshold.

17. The method recited in claim 10 , further comprising increasing an amount of force feedback output by a force feedback input device in response to the distance between the boundary of the 3D flying space and the location of the aircraft not exceeding a threshold.

18. The method recited in claim 10 , further comprising presenting a representation of the aircraft showing the location of the aircraft relative to the 3D flying space.

19. A computer program product embodied in a non-transitory computer readable storage medium and comprising computer instructions for:

obtaining boundary information associated with a three-dimensional (3D) flying space, including a boundary of the 3D flying space, wherein the 3D flying space is defined by a cross section about a center path;

continuously determining a distance between the boundary of the 3D flying space and a location of an aircraft; and

presenting, in a user interface, feedback in proportion to the determined distance between the boundary of the 3D flying space and the location of the aircraft, wherein the feedback includes at least one of resistance or force that increases in proportion to decreasing distance between the boundary of the 3D flying space and the location of the aircraft.
