FROM POH 1968 SUPER SKYMASTER
TAKE – OFF
MAXIMUM PERFORMANCE TAKE-OFF
1) WING FLAPS – “1/3” DOWN
2) BRAKES – APPLY
3) POWER – FULL THROTTLE AND 2800 RPM
4) MIXTURES – LEAN FOR FIELD ELEVATION PER FUEL FLOW INDICATOR PLACARD
5) BRAKES – RELEASE
6) ELEVATOR CONTROL – MAINTAIN SLIGHTLY TAIL-LOW ATTITUDE
7) CLIMB SPEED – 86 MPH (WITH OBSTACLES AHEAD)
8) LANDING GEAR AND WING FLAPS – RETRACT (AFTER OBSTACLES ARE CLEARED)
NOTE: WHEN TAKING OFF FROM A GRAVEL OR CINDER FIELD, THE POSSIBILITY OF GRAVEL DAMAGING THE REAR PROPELLER FROM THE FRONT PROPELLER SLIPSTREAM CAN BE REDUCED CONSIDERABLY BY USING 1/3 FLAPS, AND USING ONLY THE REAR ENGINE FOR INITIAL ACCELERATION. WHEN DOING THIS, THE NOSE GEAR SHOULD BE RAISED CLEAR OF THE GROUND AS SOON AS POSSIBLE, FOLLOWED BY FULL THROTTLE APPLICATION ON THE FRONT ENGINE.
FOR SHORT FIELD LANDINGS, MAKE A POWER APPROACH AT 90 MPH WITH FULL FLAPS. AFTER ALL APPROACH OBSTACLES ARE CLEARED, PROGRESSIVELY REDUCE POWER. MAINTAIN 90 MPH APPROACH SPEED BY LOWERING THE NOSE OF THE AIRPLANE. TOUCHDOWN SHOULD BE MADE WITH THROTTLES CLOSED AND ON THE MAIN WHEELS FIRST. IMMEDIATELY AFTER TOUCHDOWN, LOWER THE NOSE GEAR AND APPLY HEAVY BRAKING AS REQUIRED. FOR MAXIMUM BRAKE EFFECTIVENESS AFTER ALL THREE WHEELS ARE ON THE GROUND, RETRACT THE FLAPS, HOLD FULL NOSE UP ELEVATOR AND APPLY MAXIMUM POSSIBLE BRAKE PRESSURE WITHOUT SLIDING THE TIRES.
ALL OF THE ABOVE IS IN THE POH. HERE’S MY TWO CENTS.
MY AIRCRAFT IS EQUIPED WITH A STOL SYSTEM AND I WILL USE UPTO ½ FLAPS ON MAX PERFORMANCE TAKE-OFF. I NORMALLY ROTATE AT AROUND 75 MPH, RETRACT THE GEAR, FLATTEN THE CLIMB, DROP TO 1/3 FLAPS, AND CONTINUE TO ACCELERATE TO 110 MPH AND THEN LOOSE THE REST OF THE FLAPS.
IN THE MAX PERFORMANCE T/O DATA, IT REFERS TO “LEAN TO FIELD ELEVATION”. IN THE FLAT COUNTRY (MID-WEST) THIS IS NO BIG DEAL BUT WHERE I LEARN TO FLY IF YOU DO NOT LEAN THE FUEL YOU MAY NOT MAKE IT OFF THE RUNWAY. I HAVE BEEN AT 8,000 FT ON THICK, ‘ROUGH SURFACE’ AND YOU PULL THE MITURES BACK TO ACHIEVE THE MAX PERFORMANCE. IF I REMEMBER AT 8,000 FT AND DENSITY ALTITUDE AROUND 10,000 FT AT TIMES I WOULD LEAN BACK TO 12 -13 GALS PER HOUR FOR TAKE OFF. REALLY IMPORTANT!
WITH THE PERFORMANCE OF THE SKYMASTER IF YOU HAVE TO APPLY MAXIMUM POSSIBLE BRAKES THEN THE STRIP IS TOO SHORT OR YOUR APPROACH WAS NOT CORRECT. I HAVE BEEN IN AND OUT OF 1400 FT FIELDS AT 4,000 FT ALTITUDE WITH SOME DENSITY FACTORS BUT NORMALLY LIGHT ON WEIGHT. HOPE THIS HELPS.
