VOR navigation radios are normally autotuned by the FMC. The NAV RADIO page displays the tuned VOR frequencies, identifiers, tuning status and current radial for both VOR receivers. The VORs can be tuned remotely from this page.

VOR L/R - The tuning status is displayed adjacent to left and right VOR frequencies. Entry of a frequency or identifier remotely tunes a VOR. The FMC autotunes VORs and their related DMEs for procedure flying and radio positions. The tuning status displays are:

  • A (autotuning) - FMC selects a navaid for best position orientation.
  • P (procedure autotuning) - FMC selects navaids for approach or departure procedure guidance.
  • R (remote tuning) - VOR frequency or identifier has been entered by the flight crew on the NAV RADIO page.
  • M (manual) - VOR is manual-tuned using the VOR control panels on the glareshield. Manual-tuning takes priority over FMC autotuning.

    • Valid entries:

  • VOR or non-ILS DME identifier.
  • VOR frequency (XXXX or XXX.XX) The identifier and frequencies are green and tuning status is white.

    • RADIAL - Displays the current radial from the left and right VOR stations to the airplane.
