You won’t realize how helpful consistent heading and altitude instructions can be. This is something I’ve teaches all Radar trainees for years.
For example at YSCB, pilots are performing radar patterns for a training session. Runway 35 is in use.
Turn right heading 140 at 6000ft, 170 at 6000ft, 250 at 5000ft, 320 clear at 5000ft, and repeat. Then don’t deviate from those instructions to make it more predictable.
Use the least amount commands as possible, they add up.
Even the small 10 degree changes can drastically change things. You want it to be so easy that you could close your eyes for 30 seconds, open them, and you’d know where the aircraft should be. Completely predictable movement you can reproduce.
And if someone is deviating from the path you’ll immediately realize they’re not following instructions. It reduces your mental workload and allows you to focus on other things.
