Fine Tuning the K factor
Aircraft installation will affect K factor. Because of this you should ‘fine-
tune’ the K-factor, for your aircraft, as described below:
1. Fill each aircraft tank that each engine will run from (note: engine
return lines must return the fuel to each respective tank). ‘Refuel’ EDM,
noting that ‘USED’ resets to zero for each engine.
2. Fly aircraft for 2 to 3 hours. Immediately after engine shutdown, record
EDM ‘USED’ parameter for each engine in chart below.
3. Refill each tank and record ACTUAL USED for each tank in the in
chart below.
4. Total the EDM calculated fuel ‘USED’ and the actual fuel used
for each engine.
5. Record the current K factor here _________ and in the table below.
6. Calculate the Adjustment ratio:
Adjustment ratio = ( / ) - 1
2
7. New K Factor = x (Adjustment ratio +1).
Record the values here: Left Engine
