1. Make at least three flights of about two to three hours each. Note
the actual fuel used (as determined by topping the tanks) and the
EDM calculation of the fuel consumed for each flight = USD.

2. Total the EDM fuel used and the actual fuel used.
3. Record the current K factor here ____________________ and in
the table below.
4. Calculate the New K Factor as follows:
New K Factor = (EDM fuel used) x (Current K factor)
(actual fuel used)
New K Factor = ( ) x ( )
( )
Every time you fine tune the K factor, record the measurements here:

Setting the K factor
This procedure differs somewhat from setting other parameters. If you
haven’t already done so, start the pilot programming procedure by
simultaneously holding the STEP and LF buttons for a few seconds until
you see the word PROGRAM appear.
1. Tap STEP button to advance to the KF-SET screen KF=29.90 .
2. Hold both the STEP and LF buttons for a few seconds until the first digit
flashes (shown here as a larger digit for illustration purposes): 29.00
3. Tap or hold the LF button to change flashing digit: 19.00
4. Tap STEP button to move to next digit: 19.00
5. Tap or hold the LF button to change flashing digit: 18.00
