Take-Off & Climb - Continental Motors GTSIO-520 SERIES Operator's Manual

unit, which can attain speeds up to 90,000 RPM, is lubricated by
engine oil from the main oil pressure system. The engine oil must be
warm, at least 75°F. to assure proper flow through the turbocharger.
The engine must not be run under high power setting until it is
certain the oil to the turbocharger has reached this temperature.
4. TAKE-OFF AND CLIMB
a. Take-Off
(1)
Set mixture to "FULL RICH" setting. Where installed, cowl
flaps should be in full open position.
(2)
Slowly advance throttle to the maximum allowable take-off
manifold pressure (39.5 inches or red line on manifold pressure
gauge - see Note 2). The recommended power setting (RPM and
manifold pressure) should not be exceeded for long periods.
(3)
Set auxiliary pump switch as instructed by aircraft
manufacturer (see Note
3).
NOTE 2 ... The turbocharger lag may boost the manifold pressure 2
to 3 inches between run-up and ground breaking speed. Always
advance throttles slowly to permit turbocharger to follow engine
speed, and assist in preventing over-boost. In cold weather the
waste-gate valve can over-boost, unless the oil is warm.
CA UTION . .. A VOID RAPID THROTTLE OPERATION.
Counterweights may become detuned during severe acceleration.
b. Climb
(1) All high power climb must be done at "FULL RICH"
mixture setting, with cowl flaps, if provided-, in full open position.
(2) During climb (immediately after take-off) observe manifold
pressure, and retard throttle to stay below 39.5 inch maximum mani-
fold pressure setting (red line). NEVER EXCEED THIS LIMIT.
CAUTION . .. OVER-BOOSTING WILL RUIN THE ENGINE AND
BE CAUSE FOR ENGINE REPLACEMENT.
