is being pulled and engine acceleration in the higher gears is

slow.

3.

The least preferred method of checking maximum

engine fuel manifold pressure is the so called "snap" pressure

a.

The "snap" method is not as reliable as method 1 and

2 because the pressure reading is of very short duration.

Gauge inertia and/or the degree of throttle manipulation also

reduces the reliability of snap pressure readings.

b.

To take snap pressure readings, attach the ST435

pressure gauge at the shutdown valve in the usual manner.
