Next, determine the increase in SWL for adjacent
Airfield index required for 34 coverages = 9.0
wheel = 27 percent (from curve in figure 3)
(from figure 2)
Therefore: ESWL = 1.28 x SWL
d. Answer. Operations are safe, since re-
= 1.28 X 39,400
quired airfield index (9.0) is less than available
ESWL = 50,400
airfield index (12).
Tire pressure = 65 p.s.i.
