7.3 Testing Procedure
Note:
Avlite recommends that all testing be done during the day.
Check function of the LI by carrying out the following:
a.
Night mode test: Cover the LI fixture and check night operation is functioning as expected. The LI should either
flash red (for ICAO Type E or FAA L-810(F)) or operate as a red, steady burning light (for ICAO Type A and B or FAA
L-810).
b.
Day mode test: Uncover the LI fixture and check day operation is functioning as expected. The LI should no longer
be illuminated.
