LX is the only company who has devices for putting flights into OLC if
you have a FES system.
I think LX is also the only company that offers an ENL suitable for
turbine
(jet) engines. The audible frequency of jets sometimes does not register
with a standard ENL that is optimized for a piston/propeller
installation.
I think you may mean a MOP type 1b box, which filters to a frequency more
common with Jet engines.
ENL is always internal to the recorder, but MOP is usually a remote sensor.
With a Jet, the main noise is from the Jet Pipe(s), so the sensor needs to
be (ideally) mounted in a suitable place to the rear of the piles, which
usually mounting the sensor at the rear of the engine bay. Hard to put a FR
there as it usually requires removing the engine to gain access.
If LXV is the only company to invest in designing, building and gaining
approval for a MOP box, it is not the fault of LXV. These are commercial
decisions by themselves and their competitors.
Also, it is OLC's decision to require a MOP type2 recorder for FES, not
IGC's.
