GPS 500 Pilot’s Guide and Reference7-8SECTION 7NRST PAGES7.8 NEAREST FLIGHT SERVICE STATION(FSS) PAGEThe Nearest Flight Service Station Page (Figure7-15) displays the facility name, bearing to, and distanceto the five nearest FSS points of communication (within200 nm of the present position). For each FSS listed, theNearest Flight Service Station Page also indicates one ormore frequencies.For duplex operations, ‘RX’ and ‘TX’ indicationsappears beside the listed frequencies, indicating ‘receiveonly’ or ‘transmit only’ frequencies. The associated VORis also provided for reference.Figure 7-15 Nearest FSS PageNumber of Pages inCurrent Page GroupPosition ofCurrent Pagewithin CurrentPage GroupCurrentPage GroupCursor onFSS NameBearing To andDistance ToFrequency(ies)VOR Identifier (ForDuplex Operation)To quickly display an FSS’s frequency fromthe Nearest Flight Service Station Page:1) Select the Nearest Flight Service Station Page,using the steps outlined in Section 7.1.2) Press the small right knob to activate thecursor (Figure 7-15)3) Turn the small right knob to scroll through thelist, selecting the desired FSS.7.9 NEAREST AIRSPACE PAGEThe last page in the NRST group, the Nearest AirspacePage (Figure 7-16) alerts the pilot to as many as ninecontrolled or special use airspaces near or in the flightpath. Alerts are provided according to the followingconditions:• If the projected course will take the aircraft insidean airspace within the next ten minutes, the alertmessage ‘Airspace ahead -- less than 10 minutes’appears. The Nearest Airspace Page shows theairspace as ‘Ahead’.• If the aircraft is within two nautical miles ofan airspace and the current course will takethe aircraft inside, the message ‘Airspace nearand ahead’ appears (Figure 7-22). The NearestAirspace Page shows ‘Within 2nm of airspace’.Figure 7-16 Airspace Message• If the aircraft is within two nautical miles of anairspace and the current course will not take theaircraft inside, the message ‘Near airspace lessthan 2nm’ appears (Figure 7-17). The NearestAirspace Page shows the airspace as ‘Ahead <2nm’.190-00181-60 Rev. G
