The IND-350A is the updated, more rugged GPS/VOR/LOC Indicator from the well-regarded Collins Microline series. The IND-350A uses a rectilinear meter movement, instead of pendulum, which makes it easier to read. The needle remains vertical throughout its range of travel, which helps the pilot to better determine the degree of correction needed to stay on course.

This indicator does not contain a VOR/LOC Converter, which permits its use with a GPS. The IND-350A, together with an Annunciator Control Unit (ACU), can be used to meet the FAA requirements for an IFR GPS installation.

The IND-350A features:

• Metal case
• Easy to read face
• Standard ARINC interface
• TSO'd

Since the Collins IND-350A does not contain an internal VOR/LOC Converter, it is designed to be used with NAV equipment that does include this converter, such as:

• Collins VIR-351 NAV
• KX-165 NAV/COMM - 14V or 28V
• KNS-80 NAV/RNAV/DME/Glideslope
• KNS-81 NAV/RNAV/Glideslope

The IND-350A is also a nice choice to use with a GPS, either VFR or IFR. Since it does not provide up/down guidance, any IFR GPS used with this Indicator should offer non-precision approaches:

• Garmin GPS-150XL VFR GPS
• Garmin GPS-155XL IFR GPS
• Garmin GNC-250XL VFR GPS/COMM
• Garmin GNC-300XL IFR GPS/COMM
• Garmin GNC-420 IFR GPS/COMM
• Apollo GX-50 IFR GPS
• Apollo GX-55 IFR (Enroute) GPS
• Apollo GX-60 IFR GPS/COMM
• Apollo GX-65 IFR (Enroute) GPS/COMM
