In the US, there's a similar, but much more relaxed, system in use:
If you're more than 3000 feet above the ground, then the altitude above MSL in feet you should be at depends on whether you're flying under Instrument Flight Rules (IFR) or Visual Flight Rules (VFR) and your heading, as follows:
- For VFR with a magnetic heading 0-179: (1+2n) x 1000 + 500 (for integer n)
- For VFR with a magnetic heading 180-359: (2n) x 1000 + 500
- For IFR with a magnetic heading 0-179: (1+2n) x 1000 + 0
- For IFR with a magnetic heading 180-359: (2n) x 1000 + 0
Magnetic heading is trivial to measure, and under the specific rules used to determine MSL altitude, thats also really easy to measure (but might produce a large error relative to the correct answer, but a small error relative to other aircraft).
In addition, below 10,000 ft, the speed limit is generally 250kias or 200kias, depending on how close to the ground and other airports you are.

There's not necessarily much difference between those two.
