GENERAL NOTES ON ASSOCIATED FREQUENCIES

For each frequency the frequency type (ATIS, Ground, Tower, ILS, etc.) and the frequency are displayed on 

the same list row.  For a frequency which has a “frequency information page”, an “i” symbol is displayed on the 

list row between the frequency type and the frequency.  If there are more than three frequencies for an airport 

waypoint index then they are displayed in a scrollable list box with only three visible at a time.
