NOTE
If a rise in TGT does not occur within
10 seconds after moving the CONDITION
lever to LOW IDLE, abort the start.
12. TGT – 1000 º 5 seconds maximum.
13. Oil pressure – Check.
14. GEN switch – RESET, then ON.
15. Engine cleanup – Perform if engine restart
is unsuccessful.
16. CABIN AIR/TEMP MODE switch – As
required.
17. Electrical equipment – As required.
18. Propellers – Synchronized.
19. POWER – As required.
NOTE
When N is below

temperatures tend to be higher than
normal. To preclude overtemperature
(1000 °C or above)
acceleration to idle speed, periodically
move the condition lever into the FUEL
CUTOFF position, as necessary.
9-12. MAXIMUM GLIDE.
gliding 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.
9-13. LANDING
INOPERATIVE.
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 the 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. Fly the base
leg as necessary to control 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, prepare for a gear-up landing; also,
unless the surface of the landing area is hard and
smooth, the landing should be made with the landing
gear up. If landing on a rough terrain, land in a slightly
tail-low attitude to keep nacelles from possibly digging
in.
