Master switchMEMORYOFF WHEN LANDING ASSURED
If airborne with insufficient runway and altitude — land aheadDO NOT TURN BACK TO RUNWAY AT LOW ALTITUDE; LAND ON BEST SURFACE WITHIN 30° OF RUNWAY HEADING
The 206H has a large useful load and may accelerate slowly; commit early to stopping on the remaining runway rather than continuing a questionable takeoff.

If start fire — throttle full open momentarily to draw fire back through intakeMEMORYATTEMPT 2–3 SECONDS OF CRANKING TO CLEAR FIRE; STOP IF FIRE DOES NOT EXTINGUISH IMMEDIATELY
This technique applies only when fire is in the induction system during start. Advance throttle fully, continue cranking briefly to draw fire into the engine and out.

NOTEThe Continental IO-540 is fuel-injected — there is no carburetor heat control. Induction system icing of the air inlet is possible in visible moisture combined with temperatures near freezing. This section addresses alternate air use in those conditions.
Symptoms — unexplained power loss or rough running in visible moisture or near-freezing temperaturesSUSPECT INDUCTION ICING
Alternate air — if equippedOPEN PER POH; DRAWS UNFILTERED WARM AIR FROM INSIDE COWL
