Introduction
The I FO-1 is a 2 ¼” (57mm) sunlight readable multifunction color display instrument. The I FO-1 has the following
features:
G-force meter
The I FO-1 is capable of measuring g-forces exerted in an aircraft up to +-10g. The I FO-1 also has the facility to record
the maximum positive and negative g-forces encountered (typically during a flight) in permanent memory, with a
password protected reset facility. It also features two independent cycle counters to capture the amount of times a preset
force has been exceeded. The I FO-1 is able to measure g-forces even if the instrument is not mounted exactly on the
vertical axis of the aircraft.
UTC and Local Time display
The I FO-1 is capable of displaying both UTC (as known as Zulu time) and local time to facilitate ordinary ATC time
reporting. Time is maintained by an internal lithium battery which can be replaced by the user.
Slip indicator
The I FO-1 can display a slip indicator. The slip indicator can be disabled in the menu system.
Battery Voltage, *Current and Charge display
The I FO-1 can be used to monitor your aircraft’s battery power supply. The I FO-1 is very useful in determining your
battery’s health, charging status, as well as the current load consumption of your aircraft. The I FO-1 can be used in both
12V and 24V aircraft and can measure voltages up to 30V DC.
The I FO-1 uses the MGL Avionics Magnetic Closed Loop Current Sensor to measure the aircrafts current load. The
I FO-1 contains a programmable low/high voltage alarm to automatically detect bad batteries and alternator failures. The
maximum and minimum voltage reached is also recorded in permanent memory.
OAT display
OAT can be shown in either degrees Celsius or degrees Fahrenheit. The I FO-1 also contains a programmable low/high
OAT alarm. The maximum and minimum OAT reached is also recorded in permanent memory.
light Timer & light log
The I FO-1 provides a 50 entry flight log that stores the start time and duration of each of the last 50 flights. The flight
timer can either be started using a front push button or from a remote input.
Stopwatch, Countdown Timer & Alarm
Stopwatch and timers can be operated simultaneously to a programmable alarm, making the I FO-1 particularly suitable
for sport flying competitions.

4.3 G- orce Setup
High Alarm:
This enables or disables the G-force high alarm.
High Alarm:
Enter the G-force threshold for when the high alarm must be activated. Any G-force above this value will activate the
alarm.
High Caution:
Enter the G-force value for the high caution.
Low Caution:
Enter the G-force value for the low caution.

Pos Cycle:
Set the positive G-force limit above which the cycle counter should increment. This would typically be set to the maximum
allowable G-force rating of your aircraft (positive G-force). The cycle count is retained if power is removed.
Neg Cycle:
Set the negative G-force limit above which the cycle counter should increment. This would typically be set to the
maximum allowable G-force rating of your aircraft (negative G-force). The cycle count is retained if power is removed.

4.4 Time Setup
Set TC Time:
This function is used to set the internal real time clock. The time to be entered must be
UTC in order for the system to operate correctly. Do not enter local time (unless it is the
same as UTC).
UTC is the same as Greenwich Mean Time (GMT) or Zulu time.
TC Offset:
Enter the UTC offset for your location. The UTC offset can be adjust in half an hour increments.
TC Display:
Select to enable or disable the UTC display.
SW Display:
Select to enable or disable the stop watch display.
TMR Display:
Select to enable or disable the countdown timer display.
ALM Display:
Select to enable or disable the alarm display.
RTC Trim:
This allows you to adjust a trimming factor that will increase the accuracy of the built in clock.

4.5 Volts Setup
Display Max:
Select the maximum value that you want the volts bargraph to show. This can give you increased display resolution. The
bargraph is only shown if the current display is disabled.
Display Min:
Select the minimum value that you want the volts bargraph to show. This can give you increased display resolution. The
bargraph is only shown if the current display is disabled.
High Alarm:
This enables or disables the volts high alarm.
High Alarm:

Zero Sensor:
Select this function to indicate to the I FO-1 that zero current is flowing through the MGL
Avionics Closed Loop Current sensor. This is best done with the MGL Closed Loop
Current sensor disconnected from the main current supplying conductor.
Gain:
Adjust the gain factor until the current is reading correctly. It will be best if a multimeter can be inserted in series with the
current supplying conductor and the gain calibration adjusted until the I FO-1 matches that of the multimeter. Please see
the MGL Avionics Closed Loop Current Sensor documentation for more information.

4.7 OAT (Outside Air Temperature) Setup
OAT Display:
Select to enable or disable the OAT display.
Temp nit:
Select whether you want the OAT to be displayed in degrees Celsius (ºC) or in degrees Fahrenheit (ºF).
High Alarm:
This enables or disables the OAT high alarm.
High Alarm:
Enter the temperature threshold for when the high alarm must be activated. Any temperature above this value will activate
the alarm.
High Caution:
Enter the temperature for the high caution. This is the lower value of the upper yellow band.
Low Caution:
Enter the temperature for the low caution. This is the upper value of the lower yellow band.
Low Alarm:
This enables or disables the OAT low alarm.
Low Alarm:
Enter the temperature threshold for when the low alarm must be activated. Any temperature below this value will activate
the alarm.
OAT Cal:
During the factory calibration a factor has been determined and entered here that will give you an accurate OAT reading.

4.8 Slip Setup
Slip Display:
Select if you would like to enable the slip indicator to be shown on the bottom of the display.
Slip Sense:
Select if you want the slip to have a high sensitivity or a low sensitivity setting.
Slip Zero:
This function allows you to set your slip indicator to exactly zero even if your aircraft tends to fly slightly wing down. The
procedure is to place the aircraft in a stable, straight and level attitude during calm flight conditions and then select this
function. To cancel the correction, place your sensor absolutely horizontal (use a spirit level) and select the function
again.
