6.1 General
This section contains instructions for the tests to be performed after installation in order to confirm
that the system has been installed correctly. Post installation tests are mandatory for all ISAT-200
installations.
6.2 Function Test
The avionics installer must perform this test immediately after installation.
1. Move aircraft to a location with unrestricted visibility of the sky.
2. Power on unit on by turning on mains power.
3. Use the ISAT-200 menu system to check the status of the Iridium Signal and the GPS
signal. A single push (press and release) of the button will scroll through the menu one
item at a time, while pressing and holding the button will select a menu item. The status
of the GPS and Iridium signals can be checked under the Info menu. A GPS sat count of
4 or better and GPS Lock confirms correct installation of the GPS portion. A MDM Sig
strength of 2 or better confirms correct installation of the Iridium portion.
4. Test proper position reporting at the default interval setting (1 minute). An acceptable
method for testing position reporting is to use STS flight following software to check if a
valid position and GPS time is reported for the installed ISAT-200. Inform the local
SkyTrac Program Manager to change the default position interval (via SkyWeb) to
another interval if required. Failure to do so will result in position report charges at one
minute intervals.
5. Check the battery status to ensure that the battery is connected and operating normally.
The battery status can be checked from the ISAT-200 menu as follows:
a. Scroll to System -> Test -> Battery
-
If the battery is connected and operating normally, either “Charging” or “Full
Chg” will be displayed.
-
If the battery is disconnected, “No Bat” will be displayed. Power off the ISAT-
200 and connect the battery as instructed in Section 3.9.
6. Check all ISAT-200 digital inputs that are required and verify that each input gives the
expected result. The digital inputs can be checked from the ISAT-200 Menu as follows:
a. Scroll to System -> Test -> Dig I/P
b. A six digit binary number is displayed (for example: 001001). The left most digit
represents digital input 1, while the right most digit represents digital input 6.
c. Activate one of the digital inputs and check that the appropriate digit is changed
from 0 to 1. De-activate the input and check that the same digit changed from 1
to 0. Note that the logic may be inverted from the intended function. This can be
handled during the remote configuration of the ISAT-200.
d. Repeat step c for each digital input used in the ISAT-200 installation.
