INTRODUCTION TO PERFORMANCE
The graphs and tables in this section present performanceinformation for flight planning at various parameters of weight,power, altitude and temperature. Examples have been pre-sented on all performance graphs.
PERFORMANCE IN ICING CONDITIONS 1. On a clean airplane (no ice build-up) stall speeds are
increased 4 knots in all configurations when surfacedeice boots are inflated.
2. Residual ice on the airplane can disrupt the airflow overlifting surfaces and may cause an increase in the stallspeeds and a change in the amount of warning providedby the stall warning vane.
3. The wings, stabilizers, and all control surfaces must becleared of frost, ice or snow prior to takeoff.
4. Ice accumulations on unprotected surfaces will decreaseclimb rates, cruise speeds, and range. Therefore, flightplanning should be accomplished for altitudes whereadequate performance margins exist.
5. Two-engine climb performance at maximum continuouspower will be reduced due to the 130 KIAS minimumclimb speed.
6. The minimum recommended holding speed in icing con-ditions is 140 KIAS.

HOW TO USE THE GRAPHS1. In addition to presenting the answer for a particular set of
conditions, the example on the graph also presents theorder in which the various scales on the graph should beused. For instance, if the first item in the example isOAT, then enter the graph at the known OAT and pro-ceed to the remaining item(s) in the order given in theexample.
2. The reference lines indicate where to begin following theguidelines. Always project to the reference line first, thenfollow the guidelines to the next known item by maintain-ing the same PROPORTIONAL DISTANCE between theguideline above and guideline below the projected line.For instance, if the projected line intersects the referenceline in the ratio of 30% down/70% up between the guide-lines, then maintain this same 30%/70% relationshipbetween the guidelines all the way to the next knownitem or answer.
3. The associated conditions define the specific conditionsfrom which performance parameters have been deter-mined. They are not intended to be used as instructions;however, performance values determined from chartscan only be achieved if the specified conditions exist.
4. Indicated airspeeds (IAS) were obtained by using theAIRSPEED CALIBRATION-NORMAL SYSTEM graph.
5. The full amount of usable fuel is available for allapproved flight conditions.

PRESSURE ALTITUDE
To determine pressure altitude at departure and destinationairports, add 1000 ft to field elevation for each 1.00 in. Hgbelow 29.92, and subtract 1000 ft from field elevation for each1.00 in. Hg above 29.92.
Pressure Altitude at Departure:
29.92 - 29.60 = 0.32 in. Hg 0.32 x 1000 = 320 ft
The Pressure Altitude at the departure airport is 320 ftabove the field elevation.
5333 + 320 = 5653 ft
Pressure Altitude at Destination:
29.92 - 29.56 = 0.36 in. Hg
0.36 x 1000 = 360 ft
The Pressure Altitude at the destination airport is 360 ftabove the field elevation.
3605 + 360 = 3965 ft
NOTEFor flight planning, the difference betweencruise altitude and cruise pressure altitudehas been ignored.
TAKE-OFF WEIGHT
Maximum Allowable Take-off Weight = 5500 lbs
Ramp Weight = 5500 + 24 = 5524 lbs
NOTEFuel for start, taxi and run-up is normally 24lbs.

Enter the Take-Off Weight graph at 5653 ft pressure altitudeand 15°C, to determine the maximum take-off weight toachieve a positive one-engine-inoperative rate-of-climb at lift-off.
Take-off Weight = 4870 lbs
TAKE-OFF DISTANCE

Ground Roll . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .2200 ft
Total Distance over 50-ft Obstacle . . . . . . . . . . . . . .3775 ft

Accelerate-Stop Distance . . . . . . . . . . . . . . . . . . . . .3960 ft
NOTESince 3960 ft is less than the available fieldlength of 10,004 ft, the accelerate-stop pro-cedure can be performed at any weight.
Take-off at 5500 lbs can be accomplished. However, if anengine failure occurs before becoming airborne, the acceler-ate-stop procedure must be performed.
The following example assumes the airplane is loaded so thatthe take-off weight is 4700 lbs.
Although not required by regulations, information has beenpresented to determine the take-off weight, field requirementsand take-off flight path assuming an engine failure occurs dur-ing the take-off procedure. The following illustrates the use ofthese graphs.

Climb Gradient . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2.6%
A 2.6% climb gradient is 26 ft of vertical height per 1000 ft ofhorizontal distance.
NOTEThe Take-off Climb Gradient - One-Engine-Inoperative graph assumes zero wind con-ditions. Climbing into a headwind will resultin higher angles of climb, and hence, betterobstacle clearance capabilities.
Calculation of horizontal distance to clear an obstacle 90 ftabove the runway surface:
Horizontal distance used to climb from 50 ft to 90 ft = (90-50) X (1000 ÷ 26) = 1539 ft
Total Distance = 9400 + 1539 = 10,939 ft
