A magnetic compass, VOR, and ADF indications are all included in a radio magnetic indicator (RMI). A fluxgate compass that is positioned far away rotates the RMI’s azimuth card.
As a result, the aircraft’s magnetic heading is always displayed. Typically, the lubber line is a triangle or marking at the top of the instrument dial.
Keep in mind that the RMI compass card shows the current magnetic heading, and the pointer always points at the station. The station is in front of the aeroplane if the needle points toward the wing. Similar to this, the station is behind the aircraft if the needle points behind the wing.
One way to address the inadequacies of the ADF is with the radio magnetic indicator (RMI). A fluxgate, a heading indicator, and a relative bearing indicator are the three elements that make up the RMI.
Some RMIs have two needles, like the one seen here, while others have just one. Both VOR and ADF navigation are possible with the RMI. The majority of single-needle RMIs contain a switch that lets the pilot choose whether the needle should point at an ADF or VOR station.
All of the RMIs in Flight Simulator are dual-needle and only output data for the ADF and VOR 2. For each needle, you are unable to choose a different radio. The VOR needle is green, whereas the ADF needle is yellow.
The global Aircraft Radio Magnetic Indicator market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
The KI 229 RMI shows your aircraft’s magnetic heading and magnetic bearings.
The KI 229 radio magnetic indicator, which is renowned for its dependability, shows your aircraft’s magnetic heading (slaved off the KCS 55A or KCS 305 Compass System) and magnetic bearings for either a VHF omnidirectional range (VOR) or an automatic direction finder (ADF).
This is done using two needles that are read over a compass card. Use the flexible KI 229 with the KN 53, KNR 615, KNR 630/631/632/633, KNR 634, KNR 665, and KNR 665A navigational receivers. It is also compatible with the area navigational systems KNS-80 and KNS-81.
It functions well with the automatic direction finder receivers KR 87 and KDF 806, as well as the compass systems KCS 305 and KCS 55/55A. either 14/28 or 5 volt illumination available.
