Vortime:
Here in British Columbia they have that on some check lists for the C150/52/72 aircraft.
In fact I would hazard a guess that excessively long check lists are used to run up the hobbs time. ( though not down wind of course )
And once more remember I have owned and operated a flight school both fixed and rotary wing. My opinions and comments are partly molded by having experienced the system from an owners viewpoint.
