14. The following data are derived from validation flights using C-FCGS and C-FTUG and
are valid for flight planning purposes.
15. Data are provided for pressure altitudes of 2,000 ft, 4,000 ft , 6,000 ft, 8,000 ft and
10,000 ft ASL (reference BB).
16. The governing conditions for cruise performance data are as follows:
a. mixture leaned to 50ºF Rich of Peak (ROP);
Do not adjust the mixture to Lean of Peak, as significant engine
damage may result.
b. standard atmospheric conditions (ISA);
c. aircraft weight of 3,100 lbs;
d. range estimates are based on full fuel tanks;
e. range estimates are based on still air; and
f. range estimates are based on a 30 minute fuel reserve.
Maximum continuous cruise power is 75% of maximum continuous
BHP.
Fuel flow and thus the accuracy of endurance and range data is
highly dependent upon the employment of optimum engine leaning
techniques.
