(19) Runway Surface Condition (RSC): RSC is the average depth covering the runway

surface measured to 1/10 inch (1 inch is equivalent to a RSC of 10). The runway surface

condition affects both the acceleration and stopping performance of the aircraft and must

be accounted for when determining takeoff and landing data. RSC types are listed below:

Wet runway, standing water

SLR

Slush on runway

LSR

Loose snow on runway

PSR

Packed snow on runway

Ice on runway

(20) Runway Length: Runway length is the paved surface length excluding any overrun.

a. Definitions

(1) Climb Speed: Normal climbs (2 engines) can be made using maximum continuous

thrust. When Climbing at maximum continuous thrust, do not exceed 260 KIAS or .69

Mach. EPR must be recalculated every 5000 feet to prevent the possibility of
