RUNWAY LIMIT GROSS WEIGHT section: A range of temperatures is listed from approximately 10. below to 20. above planned takeoff temperature. Choose the row equal to or greater than actual takeoff temperature (interpolation is authorized), proceed across to the appropriate runway column and find the (zero wind) RUNWAY LIMIT gross weight in 100’s of pounds: 1442 = 144,200 lbs. (this figure may be larger than structural limit to allow room for abnormal condition weight penalties to be applied). This weight (corrected for winds if necessary) is compared to the CLIMB LIMIT gross weight; the lesser of the two is the maximum gross weight for takeoff.
CLIMB LIMIT GROSS WEIGHT section: Using the same range of temperatures described above, choose the temperature row equal to or greater than the actual takeoff temperature (interpolation is authorized). Proceed to the right of the form under the CLIMB LIMIT column and read the CLIMB LIMIT gross weight in 100’s of

pounds: 1495 = 149,500 lbs. This weight is compared to the RUNWAY LIMIT gross weight; the lesser of the two is the maximum gross weight for takeoff.

HEADWIND/TAILWIND CORRECTION section: Using the appropriate runway column, read the headwind/tailwind pounds per knot correction (in pounds: 0220 = 220 lbs).  A headwind correction is added to and a tailwind correction is subtracted from the zero wind RUNWAY LIMIT gross weight. Tailwind correction (up to 10 knots) must be made, headwind correction is at the Captain’s discretion. (V-speeds are not valid for tailwinds.)

CHART : The Runway Analysis will have three charts. Each chart accounts for one power/flap combination. For instance, the Runway Analysis section of the flight departure papers for a 217A powered aircraft will have three charts in order of priority (power/flap: 27A/11 , 27A/15 , & 27A/4 ). Optimum flap data will not appear in the Runway Analysis.

HEADING: This data is repeated at the beginning of every part.
RUNWAY DATA section: The length of runways is given in feet. If a column is for an intersection departure as noted in either the RUNWAY COLUMN HEADING or the REMARKS section, the length of runway available from the intersection is shown. Slope is shown in percent.

REMARKS section: Any asterisked items will be explained here, such as NOTAMs, runway remarks, intersection departure notes, etc.
CREW PROCEDURES
Flight crews receive takeoff data from Load Planning via radio closeout or hard copy. The Runway Analysis in the flight departure papers is provided to allow flight crews to determine their takeoff capability in the event of a change in takeoff runway or flap setting without having to re-contact Load Planning.
Note:  The Accuload generated Pilot Weight Manifest from Load Planning takes into account abnormal conditions such as tailwind, low altimeter setting (less than 29.72), contaminated runway, or dispatch with inoperative systems. The Runway Analysis in the flight departure papers does not. If any of these conditions exist, the appropriate takeoff weight penalty from this section must be applied. If the takeoff weight penalty for an abnormal takeoff condition is not published in this section, the Flight Crew must
contact Load Planning for new data in the event of a change in takeoff runway or flap setting.
Note:  If a performance condition (weight limit, MEL item, weather or runway condition) exists that would prevent use of reduced thrust for takeoff, an assumed temperature will not appear on the Pilot Weight Manifest from Load Planning. When calculating takeoff capability using the Runway Analysis, flight crews may not use reduced thrust for takeoff if the restricting performance condition or any prohibiting Section 1 Operating Parameters are in effect.
V-Speeds for Takeoff
The Flight Crew will be provided V-speeds in the Pilot Weight Manifest (or radio closeout) from Load Planning and also in the Runway Analysis section of the Flight Departure Papers.
Note:  The Flex Temps/V-speeds provided by Load Planning via the Pilot Weight Manifest or radio closeout are based on a gross weight up to 2000 lbs. higher than actual to account for late arriving passengers and baggage. The Flex Temps/V-speeds in the Runway Analysis section of the Flight Departure Papers are based on the gross weight listed with no pad. This accounts for the differences sometimes found between Pilot Weight Manifest Flex Temps/V-speeds and Runway Analysis Flex Temps/V-speeds.
Note:  V-Speeds in the Runway Analysis may only be used if they are listed for a gross weight equal to or up to 3,000 lbs greater than actual gross weight for takeoff. If a gross weight row equal to or up to 3,000 lbs greater than actual takeoff gross weight is not listed, contact Load Planning for V-Speeds.
Note:  V-Speeds in the Runway Analysis are valid after application of any of the takeoff weight penalties in the Abnormal/Adjustments part of this section.
Note: If the Accuload system is totally down and Load Planning is unable to access it to get V-Speeds, the Flight Crew may calculate V-Speeds using the manual procedures in this section.
