The ID-824 is the most modern Narco VOR/LOC Indicator. It has a rectilinear meter movement, instead of pendulum, which means that the needle stays vertical throughout its range of travel. This makes it easier to read course deviations at a glance. The ID-824 is also TSO'd.
The ID-824 is commonly used with the following Narco NAV/COMMs:
- MK-12D without Glideslope
- MK-12D+ without Glideslope
- MK-12E without Glideslope
