airframe designer’s limitation regarding use of an autopilot system in

turbulent conditions. If an EZ altitude control system control problem is

suspected, turn off power to the system and contact Trio Avionics for

direction before further use.

3.5.5 Servo Clutch Slip

The EZ altitude control system incorporates an

important special safety feature: a clutch within the

servo that can be overridden when actived by moderate

manual stick or yoke pressure. Sensors are provided

in the servo to detect slippage of the mechanical clutch

assembly. The message “SERVO CLTCH SLIP” will

appear as a flashing amber message if the condition is

sensed.

The clutch adjustment should be set during installation so that the system can

drive the elevator control system under normal conditions but be easily

overridden by a manual pilot input. Pilot override will force the clutch to slip,

allowing the pilot to take positive control away from the EZ-1 system in

emergency situations such as unexpected traffic. On the other hand, a clutch

slip message that appears for no apparent reason is probably due to the clutch

not being adjusted properly or by extreme out-of-trim conditions, thereby not

allowing the control system to be driven correctly.

System Response – the message “CLUTCH SLIP” will flash with amber

illumination. The message is advisory in nature and will not cause a

servo disconnect.

Pilot Action – If this message occurs under conditions other than a

manual servo override, the clutch adjustment should be checked to

ensure it is tight enough to drive the control system under normal

conditions including light to moderate turbulence and normal out of trim

conditions. However, you must assure that it is set loose enough that

the pilot can easily overcome it in an emergency.

3.5.4 Servo CW (or CCW) Limit

This red message indicates the servo crank arm has been

moved to a clockwise or counterclockwise position outside of

its normal range of operation. This error will result in an

immediate servo disconnect. The cause of this error is most

likely a manual system override by the pilot.

System response – immediate servo disconnect

and servo power down. Red SERVO CW (or CCW)

LIMIT message displayed.

Pilot Action – Determine the cause of the SERVO

CW (or CCW) LIMIT message. If not due to pilot

manual override, tighten the servo slip clutch to allow

greater servo control of the elevator system.
