9-16. MAXIMUM GLIDE.
In the event of failure of both engines, maximum
glide distance can be obtained by feathering both
propellers to reduce propeller drag and by maintaining
the appropriate airspeed with the gear and flaps up.
Figure 9-2 gives the approximate gliding distances in
relation to altitude.
Maintain best glide speed. Refer to Figure 9-2
for maximum glide distances. If sufficient altitude
remains after reaching a suitable landing area, a
circular pattern will provide best observation of surface
conditions, wind velocity, and direction. When the
condition of the terrain has been noted and landing
area selected, set up a rectangular pattern. Extending
APPROACH flaps and landing gear early in the
pattern will give an indication of glide performance
sooner and will allow more time to make adjustments
for the added drag. Select a landing area of adequate
size to accommodate the aircraft, preferably free of
obstacles and smooth. Fly the base leg as necessary
to control the point of touchdown. Plan to overshoot
rather than undershoot, then use flaps as necessary to
arrive at the selected landing point. Keep in mind that,
with both propellers feathered, the normal tendency is
to overshoot due to less drag. In the event a positive
gear-down indication cannot be determined, and
unless the surface of the landing area is hard and
smooth, the landing should be made with the landing
gear up. If landing on rough terrain, land in a tail-low
attitude to keep the nacelles from digging in. If
possible, land with flaps fully extended.
9-18. LOW OIL PRESSURE.
In the event of a low oil pressure indication,
perform the following procedures as applicable:
1. R Torque 49% maximum. Oil pressure
less than 100 psi below 21,000 feet or
less than 85 psi above 21,000 feet.
2. T3 F3 Torque 1093 ft-lb maximum. Oil
pressure less than 100 psi below 21,000
feet or less than 85 psi above 21,000 feet.
3. Oil Pressure Below 60 psi Perform
engine shutdown, or land as soon as
practicable using minimum power to
ensure safe arrival.
If the L CHIP DETECT or R CHIP DETECT
caution annunciator illuminates, and safe single-
engine flight can be maintained, perform engine
Ensure the cabin floor outlets are open and
unobstructed, then perform the following steps in
sequence until the annunciator is extinguished. Allow
approximately 30 seconds after each adjustment for
overtemperature condition is considered to be
corrected at any point during the procedure that the
light goes out.
