CAUTION: With carrier pressurized
tires, static MRT checks may cause
the tires to skid, possibly resulting
in breach of the tire carcasses. (i.e.,
blown tire)
NOTE: Static runups with carrier
pressurized tires should be
accomplished at or below 90% N2, with
MRT limiters being checked after brake
release.
