gauge wire such as AWG #20 may be needed for power connections. Do not attach any wires to the outside of the instrument or route high current wires within six (6) inches of the programmer. Ensure that routing of the wiring is not exposed to sources of heat, RF or EM interference.
same line, one of which has a large static reservoir. A simple remedy for this problem if it occurs is a tee-‐fitting near the static port, and a dedicated line to the instrument. Obviously, an insufficiently-‐large orifice coupled with large static reservoirs can aggravate the problems associated with lag.
Getting Acquainted With Your Gemini PFD Gemini PFD Display The diagram at right illustrates some of the features of the Gemini PFD display. The pitch display of the Gemini PFD is velocity vector. This is not pitch attitude but rather the flight path of the aircraft.
Using the Touch Screen The Gemini PFD has a touch screen interface. It is a capacitive touch display and therefore does not require very much pressure on the display to operate.
Info Page Display The unit serial number and software revision level can be displayed by touching the right-‐center area of the display, shown below. 1-‐Touch and hold the right-‐center area to display the info page. The instrument will return to normal flight screen when the screen is released.
Gemini Series PFD Setup GPS Signal Acquisition The Gemini Series PFD has some required setup before the first flight. Ensure that the instrument is powered down until after the engine is running. Once the engine is running and with the aircraft still stationary, apply power to the Gemini.
Slip Indicator Centering It is best to center the slip indicator while the aircraft is on the ground and stationary. To center: 1-‐Touch and hold ‘control key’ in upper left corner of display. 2-‐While holding ‘control key’, touch just to the right of the slip pointer.
Setting ASI V-‐Speeds The Gemini PFD has adjustable color bands on the airspeed indicator to represent: Vs0, Vs, Vfe, Vn0 and Vne. These settings are accessed through a menu on the display. This procedure will only need to be performed one time, before the first flight.
Setting Speed Units The Gemini PFD has adjustable units for the airspeed indicator and the ground speed indicator. These setting are accessed though the same menu used to setup the V-‐Speeds. The selectable units for speed are Knots (KTS), Kilometers per hour (KPH), and Miles per hour (MPH).
Setting Altimeter Units The Gemini PFD has adjustable units for the altimeter. These setting are accessed though the same menu used to setup the V-‐Speeds and Speed units. The selectable units for the altimeter are Feet (FT), and Meters (M).
Setting Barometer Units The Gemini PFD has adjustable units for the barometer. These setting are accessed though the same menu used to setup the V-‐Speeds, Speed units, and Altitude units. The selectable units for barometer are Inches Mercury (IN HG), Hectopascal (HPA), Millibar (MBAR), and Millimeters Mercury (MMHG).
Low Airspeed Warning Setting This operation must be performed in flight. The pitot line must be connected to the instrument. To set LAS warning: 1-‐Fly at the desired indicated airspeed for the low airspeed warning setting. 2-‐Touch and hold ‘control key’ in upper left corner of display.
Flying with Your Gemini PFD Adjusting Barometer Setting The Gemini PFD has a built-‐in altimeter therefore it will be necessary to adjust the barometer setting. 1-‐Touch the lower right key to access the barometer adjust menu. (Figure 1b) 2-‐Once the menu is shown the upper left key increases the value by 0.01 in Hg.
Loss of Airspeed If the Gemini loses airspeed, or is not connected to a Pitot system the airspeed tape will become a ground speed tape. This will only occur if the ground speed is greater than Vs0 (Bottom of the white arc).
Setting DG If GPS Signal Is Lost If the GPS signal is lost the DG will enter the free gyro mode. This mode has no track or heading reference so the DG must be set against a compass heading or other directional reference. There are several options for changing the DG direction.
