Set Decimal Increment

Sets the decimal part step increment/decrement for a frequency of the COMM, NAV and the lower 2 digits of the ADF. Increments are managed by splitting the frequency in its fractional(or decimal) part and the integer part. In the ADF this process is made by dividing the frequency in upper two digits and lower to digits of the 4-digit frequency number.

See RNS Features in the beginning of this chapter for more detail.

Note: The combination of the 1st, 2nd, and 3rd digits forms the number for the increment.

  • Example: If 1st = 0, 2nd = 1, and 3rd = 5, the increment will be 15 per encoder step in any direction.
