CROSSWIND OPERATIONS
Crosswind takeoffs and landings require a special technique but not specific procedures and, as
such, do not require a dedicated checklist. Please see the amplified discussion on pages 4-27 and
4-32 for applicable crosswind techniques.
NORMAL CLIMB
1. Airspeed
ACCELERATE TO BEST RATE OF CLIMB SPEED OF 110 KIAS (See
cruise climb discussion of page 4-27)
2. Power Settings
ADJUST AS NECESSARY
3. Fuel Selector
SET TO RIGHT OR LEFT TANK
4. Mixture
FULL RICH ABOVE 85% POWER
5. Backup Boost Pump
ARMED
6. Vapor Suppression
SET TO ON (Above 18,000 ft)
MAXIMUM PERFORMANCE CLIMB
1. Airspeed
110 KIAS (all altitudes)
2. Power Settings
2600 RPM AND FULL THROTTLE
3. Fuel Selector Valve
SET TO RIGHT OR LEFT TANK (As appropriate)
4. Mixture
FULL RICH (When climbing at V
Y
or V
X
– see page 4-27)
5. Backup Boost Pump
ARMED
6. Vapor Suppression
SET TO ON (Above 18,000 ft)
CRUISE
1. Throttle Control
SET AS APPROPRIATE TO ACHIEVE 65% TO 85% POWER (20.0
to 33.5 inches of Hg)
2. Propeller Control
SET AS APPROPRIATE TO ACHIEVE 65% TO 85% POWER (2100
to 2500 RPM)
3. Mixture
LEAN AS REQUIRED (Use TIT gauge to set 1650°F or performance charts in
Section 5. Above 65% power, only rich of peak operation is permitted.)
4. Backup Boost Pump
NOT ARMED
5. Changing Fuel Tanks
PERFORM STEPS 5.1 AND 5.2.
5.1. Vapor Suppression
SET TO ON DURING FUEL TANK CHANGEOVERS
5.2. Fuel Selector
CHANGE AS REQUIRED (Switch tanks every 45 to 60 minutes,
depending on fuel flow. The maximum permitted fuel imbalance is 10 gallons (38 L).)
6. Oxygen Quantity
CHECK PERIODICALLY (Approximately every 20 min.)
7. Oxygen Outlet Pressure
CHECK PERIODICALLY (Approximately every 20 min.
8. Flowmeter or Flow Indicator
CHECK PERIODICALLY FOR OXYGEN FLOW
(Approximately every 10 min.)
9. Altitude Change
ADJUST FLOW DEVICES TO NEW ALTITUDE
10. Physiological Requirement
ADJUST FLOW DEVICE TO HIGHER ALTITUDE
NOTE
Do not pull the throttle back to idle without leaning the mixture
appropriately above 18,000 ft (Critical altitude, the engine does not produce
full manifold pressure above the critical altitude). The reduced air density is
causing an over-rich condition at idle, which floods the engine and can make
it quit. If it does quit, it is possible to restart the engine at any altitude by
