 The Davtron 903ID/LOC meets the challenge to produce a small, affordable, light weight indicator. This computer based instrument is a compact and effective component, enhancing the navigation system. The DVOR reads digitally the aircraft's radial position from the VOR station. The instantaneous To/From switching capability makes the 903 the easiest and fastest method of obtaining VOR cross checks. The Localizer mode displays course deviation numerically with the equivalent resolution of a 1/2 dot of a CDI. The 903ID takes the Morse Code identifier signal of the VOR station and displays sequentially the station letters on the single alpha-numeric display. The letters are displayed at a clear and readable rate. The 903 indicator can easily be switched to select NAV1 or NAV2 for use. The second toggle switch on the front panel selects either a To or From bearing. The small push button switch is used for calibration during installation. The 903 becomes a signal level meter when the switch is pressed. An external signal level meter is no longer required for installation. |
