The AG6 is a full service Aircraft Annunciator, Fuel Gauge, Oil Level Gauge, Volt Meter & Current Meter.  The annunciator will display many different aircraft warnings.  All devices feature user programmable alarms.  The AG6 utilizes a push-button LCD display that is backlight with a 3 color LED.  All functions are fully programmable by the user.  The push-button/display can be used for programming, acknowledging the alarms, and paging thru up to 16 different screens or "annunciator points".  The AG6 can automatically scan thru each screen or it can be done manually using  the push-button.  The pilot has the ability to mask or unmask annoyance alarms.

NOTE: Input devices not included.  It is up to the user to provide input devices such as fuel senders, shunts, oil level sensors and input switches to drive the AG6.





Display can be easily mounted in the panel anywhere you can make a square hole.  It is a snap to install !

Measures 1.25" wide by 1.0625" high  by 1.375" deep, including bezel housing



Signal input/driver board mounts lower in the instrument panel for easier wiring.  This permits a better location of inputs & connections in a crowded aircraft.  Measures 2.25" wide by  2.5" high.



The 18" ribbon cable makes it easy to install and remove if necessary.

Plugs are provided at both ends.




The AG6 will accept up to 6 input signals.  (If the audio output is used, only 5 inputs are available.)

All inputs will accept signal ranges from (0 to 0.200V) to (0 to 16.383V).  Inputs can come from simple on/off switches, aircraft shunts, resistive sensors such as fuel senders, or analog signals from other equipment.  The AG6 is compatible with capacitance type fuel or oil senders as long as the sender's output is a current or voltage proportional to the fuel or oil level quantity.  All inputs can be configured for a filter or delay.  These filter time constants are fully programmable.  Filtering may be used to eliminate noisy signals and/or lengthen signal response times.

NOTE:  Input devices are NOT included.  It is up to the user to provide input devices such as fuel senders, shunts, and  switches to drive the AG6.



There is one special input for a shunt.  It can be used to monitor aircraft current.  This shunt can be placed in aircraft's plus or minus leg of the power circuit.  No isolation is necessary.  This input will accept signals from (0to 0.050V) to (0 to 0.250V).  This is the range of most aircraft shunts.  NOTE:  If this input is utilized, input terminal #5 cannot be used.  The shunt signal will become input signal #5.



When there is a valid alarm, the display screen will blink.  If the audio output option is selected, it also will sound.  The pilot can temporarily mask or switch off any annoyance alarms using the push button.  When the alarm is masked, the display depicts a little triangle in the upper right hand corner of the screen.  It can also be easily turned back on.  The annunciator features two, three, four, or five zone alarms for maximum flexibility.  All alarm set points and alarm delays are fully programmable.


  Have you ever left your Fuel Pump on too long?

  The alarm delay is programmable from 0.0 to 409.0 seconds (6 Min. 49 Sec.).

  This allows you to program this annunciator for a wide variety of applications

  such as this one.  For this one, just wire the AG6 to your fuel pump switch.



An audio output is also provided when there is a valid alarm.  This output can be wired into the aircraft’s sound system. 

An on board amplitude adjustment is provided.

NOTE:  If the sound output option is utilized, only 5 inputs will be available.  Input terminal #6 will be used for the sound output.



The push button display is an LCD display that is backlight with an LED.  The LED color can be green, red or yellow.

Screen colors are fully programmable.  Green is used for a normal condition, yellow for caution, and red for the alarm.

The screen brightness control can be tied to aircraft's instrument lighting dimmer.




Since the AG6 utilizes one button for entering all commands, commands are entered in a simple combination of long and short button presses similar to Morse code.  The manual provides a cheat sheet that you may copy to include it in the aircraft and aircraft handbook.






Operation of the fuel gauge is depicted below.   When the fuel reaches a low level caution point, the display is yellow.  When the fuel reaches the low fuel point, the display blinks red.  The pilot can acknowledge the alarm by pressing the button.  The alarm will stop flashing but will remain red.  The audio output will also stop.






as fuel is run out


The full scale and zero offset  of the input signal can be programmed for each gauge. 

NOTE:  The AG6 Fuel Gauges and the Low Oil Level Gauge assumes a linear input signal is provided.  Most capacitive type senders

               can be calibrated to yield a linear output signal.  If your sender is calibrated linear, the AG6 will display a linear representation.



Input power is 12Vdc or 24V.  Current draw is less than 0.060A (60mA) with the LED back light on.



There are two different operating modes, manual and automatic.  In the automatic mode, the AG6 automatically scans thru each point or screen and then starts over again.  The manual mode operates in a similar fashion except that the user can use the push button to toggle thru the different screens stopping at any screen.  You can easily switch from mode to mode using the push button.









If you are NOT a gadget person and would like to simplify the programming, order the AG6 from Aircraft Extras, Inc. web site and request that we pre-program it you.  We will contact you by e-mail or phone and discuss the details of your project.



All functions are fully programmable thru the AG6 push button.  Some of the programming features are depicted below:

Annunciator/Gauge/Meter,  AG6-24V   $189.00

NOTE: This unit's inputs are scaled for 24V for full scale.  The normal resolution of any AG6 input is 1024.  If you require that

              some inputs need more resolution, we "can" scale any one of the individual inputs for 12V full scale.  This would double

              your resolution but, it would make that input a maximum voltage of 16.383V.  If you intend to utilize the shunt input

              for a current input, this is also useful to add a bit more of resolution.  This will have to be done for input #5 since the

              current input utilizes that input.  Just contact us if you require this modification for your application.
