Menu Bar Icons

There are several menu bar buttons/icons that can be used to quickly navigate to screens that are used more frequently. Below is a description of each:

Primary Flight Display


The Primary Flight Display couples many of the standard flight instruments into a single convenient display. Information displayed on this view includes:

Note: This instrument requires at least a functioning GPS to be valid. However, addition of an Attitude Heading Reference System (AHRS) to the APIC network is recommended. The Environmental Pod is still currently under development.

Moving Map Display


The moving map displays essential flight information such as heading, speed and altitude. In addition, the moving map displays the location of airports, navaids, boundaries of controlled airspace and special use areas such as restricted areas and military operation areas. Airports are always displayed; however, navaids, boundaries and special use areas may be displayed or removed to de-clutter the display. You may select what is displayed by navigating to the APIC->Settings menu and checking/un-checking the items you want displayed.

Note: This instrument requires a functioning GPS to be valid.

Vertical Navigation


The Vertical Navigation page can display a profile of terrain ahead of the aircraft as well as the vertical descent path to a selected runway.


The satellite display shows which satellites are in view and which are actively being used in the position computation. The satellite display is the first page to be displayed. The display will change to the PFD as soon as enough satellites are active to provide reliable navigation. The components of this display are:

Nearest Airports

This instrument displays the nearest airports and the bearing and distance to each as well as the ATIS, AWOS or ASOS frequency if it is available (look-ahead ATIS).

Tap any airport displayed on this screen and detailed information will be displayed for that airport. Tap the "Direct-To" button at the bottom of the airport information page and a flight plan will be created to take you from your current location directly to that airport.

Tap the "Ok" button in the top right corner to return to the Nearest Airport screen.

Note: This instrument requires a functioning GPS to be valid.

Airseed Indicator

The airspeed indicator can display Indicated (IAS), True (TAS) or Ground speed (GS) depending on what is selected. Tap the box in the upper left corner to change the selection. Ground speed is determined by the GPS. Indicated airspeed (IAS) is received from the Environmental Pod (VPod) if it is installed. True airspeed is calculated from the IAS and outside air temperature (OAT). If a VPod is not installed then only ground speed is displayed.


The altimeter displays pressure altitude if an Environmental Pod (VPod) is installed otherwise it displays GPS altitude. Pressure altitude can be adjusted for atmospheric conditions by changing the pressure value in the Kollman window. Tap the Kollman window to display the edit dialog for the pressure value.

Vertical Speed Indicator

Vertical speed is calculated as a change in altitude over time. Altitude data is received from an Environmental Pod (VPod) if it is installed; otherwise it comes from the GPS altitude.

Navigation Indicator / HSI


The Navigation Indicator is used similar to any VOR Nav indicator. Instead of dialing in a navaid radio beacon frequency you can select a navaid by tapping the "Nav" button in the top left corner and entering a 3 or 4 letter identifier. Select a radial to or from the navaid by tapping the "OBS" button in the lower-left corner and entering a value between 0 and 359. The station identifier, radio frequency, and radial from the navaid will be displayed in the upper-right corner. The CDI needle on the nav indicator should match any radio-based indicators in the cockpit since the navaid's slaved magnetic variation is taken into account. If a flight plan to a runway is active then the glide slope (GS) indicator will also be active.

The Horizontal Situation Indicator (HSI) also operates similar to a standard HSI.

You can toggle between the Navigation Indicator display and the HSI display by tapping on the center of the instrument.


This instrument displays your aircraft's N-number (just in case you forget) as well as the date, system time, estimated local time, UTC time, a 2-minute countdown timer, and a count-up timer. The system time is the time set on your PPC device. The estimated local time is the UTC time plus or minus any adjustments for the current longitude (1 hour per each 60 minutes of longitude). Since actual time zone adjustments are somewhat erratic the actual local time may be off by up to 1 hour. Future versions of Apic may implement the actual time zone boundaries so that the local time will no longer be estimated.

Engine Speed / Manifold Pressure


The RPM instrument displays engine speed and manifold pressure if "Constant Speed Prop(s)" is selected on the APIC->Settings->Aircraft page.

If 2 engines are selected on the APIC->Settings->Aircraft page then, 2 needles will be displayed on the Manifold Pressure and RPM gauge. Tapping either instrument will switch which needle is on top. A digital value for the top needle will be displayed in the center of each gauge.

Note: This instrument is active only if an Engine Pod (EPod) is connected to each engine on the aircraft and the APIC network.

Fuel Management

The fuel display shows fuel pressure, fuel flow (gph), fuel level in each tank and the amount of flight time remaining at the current flow consumption rate.

You can display up to 4 fuel levels. Set the tanks to display and the amount of useable fuel in each tank on the APIC->Settings->Aircraft menu page.

The fuel level indicator for a tank will turn amber when the fuel level in that tank goes below 25% otherwise it will be green.

The fuel remaining time will be displayed in white unless the time remaining is less than 1 hour, then it will turn amber. If the fuel remaining time is less than 45 minutes then the time will be displayed in red.

Note: This display is active only if an Engine Pod (EPod) is connected to the aircraft and the APIC network.

Engine Temperatures

Exhaust Gas, Cylinder Head and Turbo-Inlet Temperatures can all be displayed on this instrument. The min and max temperature values can be set on the APIC->Settings->Limits page. If any temperature goes above the max value it will be displayed in red.

Tap anywhere on the display to toggle between engine 1 and 2.

Note: This instrument is only valid if an Engine Pod (EPod) is connected to each engine on the aircraft and the APIC network.

Engine Parameters

Fuel Pressure, Fuel Flow, Oil Pressure, Oil Temperature, Volts and Amps can all be displayed on this instrument. The min and max values can be set on the APIC->Settings->Limits page. All values are normalized and laid out as horizontal bars so that they can be scanned very quickly and efficiently for abnormal conditions. Any value within normal operating conditions will be displayed in green. Any value out of the min and max green limits will be displayed in amber. Any value out of the min and max limits will be displayed in red.

For aircraft with 2 engines, the bar graphs will be split into two with engine 1 on top and engine 2 beneath.

Note: This instrument is active only if an Engine Pod (EPod) is connected to each engine on the aircraft and the APIC network.

Check List

Tapping the APIC->Checklist menu item will display a dialog that has a tab for PreFlight, PreTakeoff, Enroute, Landing, Shutdown and Emergency checklists. You may modify these checklists by editing the corresponding .txt files in the (install dir)\Apic\Data folder. There can be 1 of 2 types of entries on each line in these files. There can be a section divider item or a checklist item. A section divider is just a short descriptive line of text that describes the following checklist items. A checklist item is composed of an item to check and the expected state of that item. A semicolon should separate the item to check and the expected state. See the following example.

  Avionics;Master Switch ON
  Annunciator Lights;TEST and DIM
  Transponder;1200 & Standby
  Marker Beacon;TEST
  Comm Radioes;SET FREQ.
  Nav Radios;SET FREQ.
  Compass;Set to wet compass

For more information select one of the following:
Display tab

Select the "Display" tab to:

Bugs/Units tab

Select the "Bugs/Units" tab to:

Aircraft tab

Select the "Aircraft" tab to set some of the aircraft specific parameters used by APIC.

Limits tab

Select the "Limits" tab to set additional aircraft parameter limits. These are only used if an Engine Pod (Epod) is installed. The parameter limits set here are used to define the allowable ranges drawn on the Eng.Temp and Eng.Params instruments.

All of the parameters displayed on the Eng.Params instrument are normalized and laid out as horizontal bars so that the pilot can quickly scan multiple parameters in a single glance.

Connections tab

Select the "Connections" tab to define how APIC connects to the various measurement devices. APIC can connect to multiple devices either through a serial (RS232) connection or an Ethernet network. This page allows the user to define how a device is connected to APIC and to reset the connection with a device if there is a failure.

Note: APIC for Pocket PC will automatically scan for a CF Card or Blue-tooth GPS during start-up if no connection has been previously defined. If a GPS is found, APIC will set the connection to the communications port found and set the speed to 4800 baud. APIC can run with any serial GPS that outputs standard NMEA sentences.

If an Attitude Heading Reference System (AHRS) is installed, APIC will use it as the primary source of heading, pitch and roll data. Otherwise it will use GPS data to determine attitude.

Currently only the Apic-AHRS, Honeywell HMR3000 and HMR3300 are implemented. The Honeywell devices are low cost tilt compensated digital compasses and do not output valid roll data during dynamic flight conditions. As a result APIC will only use the heading and pitch data from these devices. Roll is computed from GPS data.

Up to 2 Engine Pods (Epod) can be installed. One per engine.

Currently the Environmental or (Vpod) is not selectable.

Currently the Remote Nav/Comm and Transponder connections are not available.

Eventually a remote Nav/Comm device will be used as a backup for navigation in the event of a loss of GPS signal.

Eventually a Transponder connection will be used to obtain encoded altitude data.

Airport Information

The airport information dialog for any airport can be accessed by any of the following methods:
  1. Tap on the airport symbol on the moving map page.
  2. Tap on the airport identifier on the Nearest Airports page.
  3. Navigate to the Apic->Find->Airport menu item and enter the 3 or 4 letter identifier for the airport of interest.

The first page that will be displayed is the Airport page. This page displays critical information about the airport such as:

Tricks and Tips

Frequently Asked Questions

How does the APIC attitude indicator work?

More Info

Can I add an external gyro to APIC?

Yes. An external gyro option is available.

How often is the APIC software and data updated?

APIC software is updated on a 28 day cycle. By simply purchasing the updates at a minimal yearly price you will be able to login on our website with your email and password and begin downloading the updates immediately. The updates include any software changes, new features, bug fixes, flight data and map updates.

Does APIC have weather included?

Weather integration will be available shortly.

What is Gas-n-Grub?

Gas'n'Grub is an addition to the Approach Website that has been included in the Apic software. When flying, its important to know which airports in your flight path have self service fuel and the hours of FBO’s. Also, if you are hungry you dont want to land get a rental car and drive around town for an hour looking for somewhere to eat. Therefore, Gas'n'Grub is a feature that Approach developed to help you select the most convenient stops along your route. You can easily find the nearest airports with self service fuel and those fields with a restaurant on field. (See also)

What other features will be added to APIC in the future?

We are constantly improving and updating APIC. Weather is just around the corner, also our Engine (Epod) interface will allow you to view all of your important engine information.

Can I run APIC on my PALM device?

Currently APIC is only designed to run on Windows PocketPC 2002/2003 formated devices. APIC will also work on any Windows 2000/Xp.

How much memory do I need to load APIC?

A typical install of APIC requires 18.6Mb, however if the terrain is loaded onto an SD card (which we recommend doing to improve speed and functionality on your PDA.) the install into your main memory would only be 12.2Mb. A minimal install option is also available which only requires 9Mb. (All of these files sizes are dependant on the country and/or region installed. The file sizes given here are according to the North America APIC/PDA install.)

What kind of GPS do I need?

Any GPS unit that outputs the standard NMEA sentences should work.

Can I use my Garmin GPS as input into my PDA and do you recommend this?

A Garmin GPS can be integrated to work with APIC through a cable. Approach does not recommend doing this since the price of GPS units is so low now that the added reliability and redundancy of using a second GPS makes sense.
