## INTRODUCTION

Airport analysis facilitates the determinat ion of the maximum allowable takeoff and landing weights for specific airport conditions and various airplane configurations. The limitations observed are those specified in the FAA approved Airplane Flight Manual (AFM) for the airplane.

TAKEOFF The maximum allowable takeoff weight is determined by the most limiting of the following: 1. Maximum certified takeoff weight (structural limit). 2. Climb limited weight - the maxi mum weight at which the FAA required minimum climb gradients in second segment and final segment are achievable for the ai rport elevation and temperature. 3. Field length limited weight - t he maximum weight at which the airplane complies with FAR Part 23 rules governing required runway length, airport elevat ion, temperature, and wind. 4. Obstruction limited weight - the maximum weight at which obstruction clearance required by FAR Part 23 can be demonstrated. The obstruction lim ited weight is a function of obstruction height and distance, tem perature, airport elevation, runway slope, and wind; unless ot herwise specified on the Airport Analysis, a straight out flight path along the extended runway center line is assumed for obstruction clearance.Runway Analysis Manual DHC-6-300 SEAPLANE PT6A-27 SEABORNE AIRLINES

6/29/2011 PAGE 3 LANDING The maximum allowable landing weight is determined by the most limiting of the following: 1. Maximum certified landing weight (structural limit). 2. Climb limited weight - the maxi mum weight at which the FAA required minimum climb gradients are achievable in the approach and landing configuration. The wei ght is a function of airport elevation and temperature. 3. Field length limited weight - t he maximum weight at which the airplane complies with FAR Part 23 rules governing the required runway length, airport elevation, and wind.

MANUAL & OBTAINING RUNWAY ANALYSIS Runway analysis for regular and list ed approved alternate airports are provided in this manual. In the event an aircraft diverts into an airport not listed as a regular or alternate airpor t, runway analysis is available, upon request, from Automated Systems in Aircraft Performance, Inc. (ASAP Inc.). This information is also available for other purposes such as planning purposes, sales, etc. Analysis is readily available at our w eb site for instant calculation. You may also have our staff send you the runway analysis data. Analysis is usually available within the hour; however, it may take longer depending upon the time of the day and airport for which information is requested. Runway analysis may be obtained at the following: http://www. asapinc.net

## DESCRIPTION 

# $ TAKEOFF  TAKEOFF HEADING The heading at the top of the page contains the following information:

Airport Date: The date of the last revision to the most recent runway end data by ASAP, Inc. is presented. Power Setting: Only maximum power is be used with Seaplane Aircraft

Airline Name Type of Performance Airplane Model and Engine Type Flap Setting for Takeoff ICAO four letter airport identifier / IATA three letter airport identifier Airport Location Airport Name Airport Elevation in Feet MSL 

##  NOTE TO CHECK MAX STRUCTURAL TAKEOFF WEIGHT LIMIT Note as a reminder to always check the performance limits against the specific aircraft’s structural weight limit.Runway Analysis Manual DHC-6-300 SEAPLANE PT6A-27 SEABORNE AIRLINES

#  TAKEOFF WEIGHTS Gross weight performance limits are shown in columns for the corresponding temperature. OAT: The outside air temperature in degrees. F = Fahrenheit, C = Celsius.

STATIC TORQUE PSI: The static takeoff power setting for the engines in pounds per square inch.

FIELD LIMIT WEIGHTS: Field limit weights in pounds for a no wind (Zero Wind) condition are given for a corresponding runway and temperature. This weight is the limiting weight considering the runway characteristics, and obstacles in the departure area. Interpolation for intermediate temperatures may be used or the next hotter temperature. Corrections must be applied for wind, and mel performance decrements. After correcting, the final result must be compared with the climb limit column and maximum structural weight for the lowest value limiting weight.

RUNWAY NUMBER: Up to six runways will appear in this area. A suffix to the runway number may appear, which refers to takeoff, and has the following meaning: C Center runway when there are three parallel runways L Left runway when there are two or more parallel runways R Right runway when there are two or more parallel runways I Intersection takeoff from the taxiway designator following the “I”.SEABORNE AIRLINES DHC-6-300 SEAPLANE PT6A-27 Runway Analysis Manual

PAGE 6 6/29/2011 P Prior permission required from the tower to use the runway. * Special condition such as additional or less runway length. M Obstacle clearance based on mobile equipment in takeoff path. S Obstacle clearance based on ship in channel. T Special departure procedure involving a turn for obstacle clearance. A “T” with nothing following designates a turn procedure calculated on a conservative side which is valid for all aircraft type. If “IA6” follows the “T”, the turn procedure was developed based on Seaborne DHC-6-300/PT6A-27 specific performance. General turn procedures are designed for V2 speeds between 90 – 200 Kts. These engineered turned procedures are designed to avoid the obstacles with an engine failure while climbing to the level off altitude. These engineered turn procedures will most likely coincide with ODP (obstacle departure procedures) or SID’s (standard instrument departures). In areas where this cannot be done, the turn procedure will be different. In cases where the terrain does not permit higher V2 speeds, the maximum V2 speed will be printed in the procedure. (This is common where the turn procedure terminates in a holding pattern.) The pilot or operator must check the actual V2 speed (based on actual takeoff weight) prior to departure to see if this speed will be exceeded. Takeoff weight must be reduced as to not exceed the procedure maximum V2 speed. If the turn procedure terminates in a holding pattern, the maximum V2 will still apply to throughout holding pattern. The turn procedure terminates at level off altitude or higher in accordance to the altitude printed on the performance page LOA for that runway end. The pilot, dispatcher or operator must determine the next course of action beyond this point.Runway Analysis Manual DHC-6-300 SEAPLANE PT6A-27 SEABORNE AIRLINES

6/29/2011 PAGE 7 TR Special departure procedure requiring RNAV navigation. The same criteria for standard turn or custom turn procedures in the above paragraph still apply.

D Runway length available day use only. N Runway length available night use only. LIMIT CODE: The limiting c ondition is presented for the corresponding temperature. Following are the abbreviations: R - Runway C - Climb O - Obstacle SEC. SEG CLIMB: Climb limit weight in pounds is shown for the corresponding temperature. This weight is the limiting weight considering the governing regulatory minimum climb requirements as designated in the aircraft flight manual. Interpolation for intermediate temperatures may be used or the next hotter temperature. Corrections must be made for any mel performance decrements. After correcting, the final result must be compared with the field limit column and the maximum structural weight for the lowest value limiting weight.



##   WIND CORR - WIND CORRECTIONS Wind corrections provided have already been calculated using not more than 50% of the actual headwinds, or not less than 150% of the actual tailwinds, in compliance with relevant operating regulations. Performance corrections are made for the wind com ponent parallel to the runway, that is actually reported by the tower (since the weight corrections already consider the percentage usable in comp liance with the relevant operating regulations). Gross weight corrections are listed for each runway. ADD LBS/KT HW: Adjustment in pounds to be added for each knot of headwind.SEABORNE AIRLINES DHC-6-300 SEAPLANE PT6A-27 Runway Analysis Manual

PAGE 8 6/29/2011 SUBT LBS/KT TW: Adjustment in pounds to be subtracted for each knot of tailwind. ‘N/A’ means runway Not Authorized for use with any tailwind. 

##  RUNWAY DIM - RUNWAY DIMENSIONS Runway length: Takeoff run available length in feet for each runway. Runway slope: Runway slope for each runway. An average slope is shown as positive for uphill and negative for a downhill slope. Data for this runway has been calculated based on this slope value.



##   LVLOFF ALT - LEVEL OFF ALTITUDE Level off altitude is listed for each runway, in feet msl, for engine failure acceleration/flap retract hei ght of 400 feet above the airport or higher if necessary for obstacle clearance.



##   SPECIAL PROCEDURE OR NOTE Special non-standard departure procedures, for engine failure, such as turns will be described in this area for each runway. Other significant notes may also appear. The area will be empty for standard departure procedures.Runway Analysis Manual DHC-6-300 SEAPLANE PT6A-27 SEABORNE AIRLINES
