9.1.3 Enter Vertical Speed (VS)
To enter a vertical speed, press the encoder switch to
advance to the VS MODE screen. It will initially indicate a
“0” vertical speed. To initiate a climb or descent, just dial
in the climb or descent rate and press the LCD switch.
The aircraft will then begin to climb or descend at the
vertical speed that was entered. The mode of operation
here is the same as it is in the EZ-2 system.
If at any time a capture altitude is desired, the pilot can toggle to the ALT PRSLCT
screen and set the desired altitude as previously described
If the VS is left at “0” (and not engaged) and the encoder is pressed again, the
display will advance to the ALT PRSLCT screen. If an altitude is entered and the
system is engaged, the vertical speed will default to the value stipulated in the
setup menu and the aircraft will begin to climb/descend. This is set to 500 fpm at
the factory, but may be changed by the user when in the setup menu.
9.1.4 Enter a Destination Altitude
To enter a destination altitude, press the encoder button
to toggle to the amber ALT PRSLCT screen and rotate
the encoder knob to select the desired altitude. Let’s
assume that we wish to climb to 7,500 feet. Rotating the
encoder switch will increment the value by 100 ft. per click
– Pressing
and rotating will increment the value by 1,000
ft. per click) Once the proper altitude is displayed by
rotating the encoder switch, press the LCD switch to
engage the climb.
The LCD screen will briefly display the BARO ALT screen
so we can check the EZ-3 altimeter against the aircraft
altimeter. This display automatically times out 5 seconds
after a change is made. Once the timeout occurs (or the
LCD switch is pressed again) the LCD screen will display
the default climb or descent rate, alternating with the
destination altitude.
Once at the destination altitude of 7,500 feet, the system will enter the ALT HOLD
mode and the aircraft will level off and hold that altitude.
The ALT PRESLCT screen may be selected at any time and, if active (green), the
pre-selected altitude may be adjusted. (As the encoder is rotated, the screen will
change from green to amber, indicating that the new target altitude has not been
invoked). Any changes made while this screen is present are activated by
pressing the LCD switch as noted previously.
Additionally, to cancel the pre-selected altitude, toggle to the active ALT PRSLCT
screen and press the LCD switch without rotating the encoder knob. The screen
will now turn amber indicating the mode is inactive.
