Approach Climb And Landing Runway Limit Charts
If a landing must be made at a field not dispatched to, the approach climb and landing runway limit gross weights should be checked to assure a safe landing. The lesser of approach climb limit weight or landing runway limit weight is the normal maximum allowable landing weight.
Accumulated Ice Penalty
When icing conditions are predicted during takeoff and/or enroute and the predicted landing temperature is below 68. F, the “Ice Protection Off or Engine Ice Protection Only” approach climb limit weight must be reduced by an accumulated ice penalty. This reduction is required to account for the ice remaining on the non-heated structure after the ice protection systems have been cycled. The accumulated ice penalties are as follows:
-217 &-217A Power -appoach flaps 11.: 1,250 lbs -217 &-217A Power -appoach flaps 15.: 1,400 lbs
Example Problem:
Aircraft: 120,000 lbs. gross weight / -217 / all systems operating Runway: Elevation 5,000 Ft / Length 8,000 Ft / Wet runway Weather: Winds calm / Temp 80.F
Determine the max allowable landing weight.
Enter the -217, Flaps 15 approach climb limit chart on page 60 at the row for 80.F. Proceed to the right until under the column for elevation 4001 -6000 feet. The approach climb limit weight is 129,500 lbs.
Enter the landing runway limit chart for flaps 40., elevation 4,001 - 6000 feet, wet runway on page 66 at the row for runway length of 7,001 - 8,000 feet. Proceed to the right until under the column for 0 wind and all systems operating. The landing runway limit weight is 130,000 lbs.
The lesser of the two is 129,500 lbs. and this is the maximum allowable landing weight for these conditions. Since the example aircraft weighs 120,000 lbs., a safe landing is possible.
