Intelligent Flap Controller (IFC) is an electronic controller designed
specifically to operate DC motor actuators including the Van’s Aircraft series of
Flap Actuators used in RV type homebuilt aircraft. IFC connects to the standard
up-off-(down) switches commonly used to control flap operation and directly
drives a Van’s flap actuator. IFC allows for Pilot and Co-pilot flap switches and
resolves the possible conflicts if the switches are operated in opposite directions.
IFC requires NO flap position sensor and is fully compatible with Safety-Trim
servo controllers.
IFC provides flap positioning presets that are easily set without having to
adjust a position sensor. Additionally, IFC includes a manual mode of operation
to raise or lower the flaps in proportion to the time the flap switch is held closed.
IFC receives switch inputs from Pilot and Co-pilot flap switches such as
those found on the Infinity Stick Grips. These switches provide a momentary
closure for Flaps Down and a maintained closure for Flaps UP. The switch
closures are referenced to a common ground. Based on the switch inputs, IFC
directly drives the flap actuator. IFC resolves any conflicts between the Pilot and
Co-pilot switches as well as any switches left in the maintained UP position.
Flap positions such as 0,10,20,40 degrees are selected by simply
pressing the flaps down switch for a momentary action of less than 1 second. If
flap positions other than those preset in the controller are desired the switch may
be held for longer than 1 second, giving manual control of flap position. When
the switch is released the flaps stop at their current position.
Additionally, when used with an ASW-1 airspeed switch IFC provides Vfe
protection by preventing flap deployment above a preset air speed. However,
IFC will not limit the flaps from being retracted regardless of airspeed.
The ASW-1 airspeed switch may be shared with a servo controller Safety-Trim
for system integration.
The Van’s flap actuators have no internally electrical limit switches and will
run continuously if not controlled. IFC prevents the flap actuator from running
endlessly when a flap switch is left in the UP position. After a 15 second
timeout, the flap actuator is shut off. Simply move a flap switch to the off or
down position to reset the operation of the flap actuator.
IFC is to be used with DC Flap Actuator motors rated for operation at 12-
24 volts DC and up to 10 amps continuous, 15 amps peak. No other uses are
permitted. The Flap Actuator must be mechanically or electrically limited for
travel length as the IFC unit does not set the minimum and maximum travel
lengths for the flap actuator. The Van’s flap actuator satisfies this requirement.
IFC is not TSO’d and must only be used in aircraft certified in the
Experimental category.
Flap input switches for DOWN actuation must be of the momentary
closure type. Flap input switches for UP actuation may be either momentary or
maintained type.
Compatible wiring harness model number: IFC-10-Harn
3 Rev 1.1 © 2015 TCW Technologies, LLC
IFC must be installed using the current aircraft standards and practices.
Refer to AC 43.13-2A/1B. The installer/builder is solely responsible for
determining the suitability of the installation and use of this product.
Installation instructions:
1) Connect the wiring harness as shown in the wiring diagram.
NOTE: Double power, ground and motor wires are ONLY required when
the flap actuator requires more than 7.5 amps continuous current. When
using the standard Van’s aircraft flap actuator double wires are NOT
required.
2) WHITE #20 gauge wire to + Aircraft Power via a 7.5 amp fuse or circuit
breaker.
(if using double WHITE #20 connect via a 10 amp fuse or c.b. )
BLACK #20 gauge wire(s) to – Aircraft ground.
(as shown on the wiring diagram)
3) Flap switch wires: DO NOT mix the pilot and copilot switch wires
PILOT: Blue #22 Flaps UP
Violet #22 Flaps DOWN
Co-pilot Orange #22 Flaps UP
Yellow #22 Flaps DOWN
4) Common (center) terminal of the Pilot and Co-pilot
flap switches and to the Airspeed switch (ASW-1) to ground of pin 7 or 15
Alternately aircraft chassis ground may be used instead of the connection
to pin 7,15 for the flap switches and airspeed switch.
5) Flap Actuator motor:
Red #20 to Flap Motor +
Green #20 to Flap Motor -
NOTE: This polarity must be used to drive the flap actuator in the UP
direction.
DO NOT LET THE FLAP ACTUATOR WIRES TOUCH EACH OTHER
OR GROUND!
