2.8.4.3. ON-Mode Test : Saves the existing test result data and proceeds to check
the ELT’s in a live ON-Mode. In ON-Mode the ELT is transmitting as it
would be when it is activated. Please be aware of the dangers in carrying
out this mode. Please note when a ELT is tested in test mode i.e. not
operational unless the GPS in the system has live data the ELT will
default to LAT 127 degrees and LON 255 degrees.
2.9. Example of a good Test with ELT Data displayed correctly.
Data is received, Power and Frequency are both good.
2.10. At this point of the test if failures are experienced. There are several possibilities that
may be causing the failure these are:
2.10.1. No data (and no power) and no frequency. This would indicate that the antenna
is not picking up any signal. Reducing the distance between antennas is the
only way to rectify this. Naturally, if the ELT does not transmit anything, there is
no chance of receiving anything.
2.10.2. A frequency is displayed but it is not /-2 kHz of one of the four ELT
frequencies. In this situation it may be best to STOP the test and restart from
the beginning.
2.10.3. A frequency is displayed which is /-2 kHz of one of the four ELT
frequencies. This frequency will be used as the default for further testing and
should not be changed. If the displayed frequency is different from the selected
