Sat the same exam yesterday and am pretty sure the question was as follows:
(Use Performance Manual MEP Figure 3.7)
What is the two engine rate of climb given the following conditions:
OAT -20 C , PA 18000 ft, Gross mass 4000lbs. Mixture leaned to 25 F rich of peak EGT, other conditions as given in header.
a) 1370 ft/min
b) 700 ft/min
c) 550 ft/min
d
1050 ft/min
As posted by Rene and bjkeates, I also went for 1050 ft/min.
I guess they were looking for the inclusion of the Lean mixture for the extra points.
