This STC also provides the data for installation of optional remote HTAWS annunciators and optional
cyclic stick switches for remote control of COM and HTAWS functions.
The 400W Series unit can interface to the Garmin G500H system GDU 620 PFD/MFD for display of
navigation information and HTAWS annunciation.
Rotorcraft modified under this STC are restricted to VFR only, including rotorcraft that may not have
previously been restricted to VFR. To clarify this operation limitation, a placard with the text,
“APPROVED FOR DAY/NIGHT VFR” is required to be in the pilot’s view.
The installed equipment is connected to an avionics bus that receives power as soon as the battery and
avionics master switches are turned on. Circuit breakers are installed in the panel located in existing
overhead console, as shown below. (Note: circuit breakers for dual navigator installation are shown).
