| 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.
Installation Eligibility Beech Models 35, A35, B35, C35, D35, E35, F35, G35, H35, J35, K35, M35, N35, 35-33, and 35-133. If your airframe is not listed for the unit you're installing you need to complete a 337 form and file with your local FSDO.
