Example: The sample problem on page 9 calculated a Runway Limit gross weight of 155,300 lbs. If the right engine hydraulic pump were inoperative, the takeoff weight penalty for a flaps 11. takeoff on runway 8 is 1300 lbs. (Interpolation between 1300 and 1200 is authorized if necessary.) The corrected Runway Limit Gross weight is 154,000 and the Climb Limit gross weight remains 149,500 yielding a maximum allowable takeoff weight of 149,500 lbs.
Approach Idle Fail High - ARTS Not Reset
If the Flight Crew uses the Runway Analysis in the Flight Departure Paperwork to determine takeoff capability, the appropriate takeoff weight correction from the table below should be subtracted from the maximum runway limit weight.

Example: The sample problem on page 9 calculated a Runway Limit gross weight of 155,300 lbs. If the approach idle system fails to high, the takeoff weight penalty for a flaps 11. takeoff on runway 8 is 9100 lbs. (Interpolation between 9100 and 9000 is authorized if necessary.) The corrected Runway Limit Gross weight is 146,200 and the Climb Limit gross weight remains 149,500 yielding a maximum allowable takeoff weight of 146,200 lbs.
V-Speeds for Takeoff - Manual Calculation
Policy & Examples
Note: The following procedure for manual calculation of takeoff V-speeds is for use only when the Accuload system is totally “down” and the Load Planner is unable to use it to prepare the weight manifest. It is not to be used when the Accuload system is in operation.
The instructions for manually calculating V-speeds are on the front of the appropriate (-217 or -217A) foldout page in this section.
Note: Flex (reduced thrust) takeoffs are not authorized when using V-speeds calculated with this procedure.
Example problem #1
Flight 486 LAS to IAH LAS runway 25R
Aircraft 806 / -217A Elevation 2175’
Gross Weight 144,000 Runway slope +1.03
Flaps 4. Ambient temp 95.F
Note that in this problem VR was increased to equal V1.

Example problem #2
Flight 1573 IAH to AUS IAH runway 14L
Aircraft 870 / -217 Elevation 98’
Gross Weight 100,000 Runway slope -.08
Flaps 11. Ambient temp 35.F
Note that in this problem minimum speeds need to be used for takeoff.
