GENERAL
This section will give you the basic parameters and considerations for using your RV-12iS. Each phase of flight should
be considered during pre-flight planning. Read through the information in the sections within the remainder of the FTS to
help prepare for each phase of the upcoming flight.
BASICS OF LOADING THE RV-12iS
The RV-12iS design places the pilot and passenger forward of the CG and baggage/other payload aft of the CG. Thus,
the most-forward loading condition occurs with the heaviest possible pilot and passenger weights combined with
minimum fuel and no baggage. Conversely, the most-aft loading condition occurs when there is a very light pilot, no
passenger, full fuel and maximum baggage.
The forward CG limit is established by the strength of the nose landing gear, by the amount of pitch trim authority
required to trim the aircraft to 1.3 times stall speed with power off and flaps fully deployed, and by the pitch control
authority required to rotate the aircraft to a landing attitude in ground effect, with power off and flaps fully deployed.
The aft CG limit is established by minimum pitch and yaw stability requirements.
WARNING
Loading the aircraft such that the CG falls outside the allowable range compromises safety and may result in
injury or loss of life as well as damage to the aircraft.
COLD WEATHER OPERATION
The minimum operating temperature of the aircraft is -20
O
F (-30
O
C) and is limited by the EFIS.
SEVERE COLD:
•
Drain the fuel system if the temperature falls below -30
⁰
F [-34
⁰
C].
WARMING OIL/BLOCKOFFS:
Engine RPM is limited until the oil reaches the minimum operating temperature. On cold days it will take longer to raise
the temperature to the minimum temperature. Installing cooler blockoffs as described below will aid in heating the oil. To
raise the temperature more rapidly, run the engine at the highest rpm allowed. Even though more air will be pushed
through the coolers by the propeller at higher rpm, this cooling effect will be more than offset by the extra heat
generated by the engine at higher rpm.
You may install oil cooler and radiator blockoffs as required to allow the oil to reach minimum operating temperatures.
When installing blockoffs make sure to placard the panel as a reminder that blockoffs are installed. This will help ensure
the operator is aware of the installation and in turn prevent inadvertent overheating concerns when flights are made from
cold to warm weather conditions with the blockoffs mistakenly left in place.
FUEL SYSTEM CONSIDERATIONS:
It is imperative that the aircraft fuel system be properly checked at the fuel strainer valve and verified to be free of
contaminants and water:
•
Prior to flight as part of a pre-flight walkaround check.
•
After the aircraft has been parked on the ground in conditions that are conducive to water entering the fuel
system or with a partially full tank where condensation may form on the empty sides of the tank.
•
After flight through precipitation in which water may have entered the fuel system through the fuel cap vent
or worn seal or operations in humid conditions.
•
After fueling the aircraft. For further information see the FTS section on fueling the aircraft.
