Hey? So at 120 kts you are going to fly 30 degs for 2 mins for every mile off track???
That wont work..
At 90 kts its 40 deg for 1 min per mile off,
at 100 kts its 34 deg for 1 min per mile off
120 kts ....30 deg...
to requote the other thread....

'Standard Closing Angle' is the simplest method we've found for correcting tracking errors and 'proportional correction' for timing errors. No need for lines on the chart such as those ancient 5 deg and 10 deg driftlines!! And no hard sums either. To summarise:
STANDARD CLOSING ANGLE
1. Establish your distance off track.
2. Turn towards track by a Standard Closing Angle of 60/(TAS in miles per minute) i.e. 40 deg for a 90KIAS Cherokee, 30 deg for a 120KIAS Bulldog.
3. Hold that heading for the same NUMBER of minutes as you were miles off track , i.e. 3 minutes if you were 3 miles off track.
4. Turn back onto original heading , recheck DI is synch'd and the rudder trim is correctly stopping flight with a constant yaw.
5. Adjust timing by adding 1/3 of the time spent on the Standard Closing Angle at 90KIAS or 10 sec per minute at 120KIAS.
It's easy and it works!!
