OUR OPINIONS ON NAV/COM AVIONICS
Brought to you by
APG - Eastern Avionics International
The Nav/Com is a product category that every pilot is familiar
with but few really know well. As a general rule of thumb, if your old Nav/Com
has only 360 channels or was built before 1976, you should probably replace
it rather than try to get it fixed the next time it breaks.
Many parts that were commonly used in older radios are no longer
being made. Many of them are a first generation solid state design that were
not very good to begin with. Additionally, tolerances on components change
over time. Often, a good part installed to replace a defective one won't work
in the circuit because the associated components have simply gone out of tolerance.
Your local avionics shop can also spend many hours trouble-shooting (on your
dollar!) before finding that the replacement parts are unavailable. Whether
a radio is two years old and worth $2,000 or 20 years old and worth $200,
the shop will charge you the same hourly rate to locate the needed fix. Essentially,
investing repair money in a radio worth $200 is not a wise decision.
According to the latest FAA information, you can no longer use
communication radios that do not meet the .003 frequency stability specification
in any case. Many 90 and 360 channel radios now still in aircraft are therefore
illegal to recertify. Essentially all tube type and many transistorized radios
manufactured before 1978 are not legal.
Here are some models we consider fine choices for the money
(VOR/ILS indicators are generally priced separately)....
