Warm Up And Taxi; Run-Up; Take-Off And Climb - Titan 340CC Operation Manual

3.2 Warm Up and Taxi

1
Engine cooling is dependent upon airflow through the cowling and oil cooler.
The section of the propeller in front of the cowl cooling inlet is generally very
ineffective, and forward speed of the airplane may be necessary during high
temperature conditions to keep the engine from overheating.
during ground operation can produce a condition called "Glazed Cylinder Bores"
at any time in the engine's life, but the cylinders are most susceptible during the
first few operating hours. Reference is made to SB 88-7-1 and Manual M101:
Break-In Instructions for Cylinder Overhaul or Cylinder Replacement
2 The engine should be warm enough for taxi as soon as it takes throttle with no
hesitation. Trying to keep taxi distances short is not always possible, and there
should be no significant engine distress from long taxi distances after engines
are properly broken-in. However, the engine temperature should be monitored,
especially during hot weather. Additionally, taxi safety should not be compromised!
If high temperatures are noted during taxi, then the engine installation should be
examined to establish and fix the root cause.

3.3 Run-Up

Follow the airplane manufacturer's recommendations for similar engines.
However, the following procedure may be used.
1 If possible, head airplane into wind.
2 Mixture: FULL RICH
3 Throttle: 1700 RPM
4 Ignition: Switch to left and then right, a slight change in RPM is normal but engine
should continue to run smooth on either ignitions.
5
Carburetor Heat Control (Carburetor Engines):
DECREASE

3.4 Take-Off and Climb

1
Mixture: FULL RICH (Note: at high altitudes, some leaning to obtain smooth
operation may be required)
2
Carburetor Heat Control (Carburetor Engines): OFF (Full in position on most
airplanes)
a Carburetor heat may be required during climb to prevent the formation of ice on the
air throttle valve. The use of carburetor heat causes the engine to run slightly richer,
and some roughness may be experienced. Sometimes this can be helped by leaning
the mixture slightly.
3
Throttle: ADVANCE SLOWLY AND SMOOTHLY (If engine does not respond properly
to throttle, then abort take-off and determine cause)
