EXAMPLE 1— NEW GPS APPROACH
Example 1 uses the GPS approach into Frederick Municipal Airport (KFDK) and
illustrates the basic sequence of selecting and flying a GPS approach, and flying
directly to a missed approach holding point. Please refer to the previous sections of
this chapter for expanded keystroke instructions.
1. Select the destination airport (KFDK) using the
D
key, or create and activate a route
to the destination airport.
2. Select the desired approach (gps rw05) from the Approach Select page. The GPS 155
will automatically select MRB as the IAF since it is the only IAF available.
3. 30 nm from the destination, set/confirm the GPS APPR switch to the ARM position. The
CDI will automatically begin a smooth transition from the 5.0 nm to the 1.0 nm scale.
4. Enter the current altimeter setting of KFDK on the Position page when prompted with the
‘Need pres- press NAV’ message.
5. Fly the approach. The GPS will provide navigation to each approach waypoint in sequence:
• MRB (Initial Approach Fix)
• SUSII
• BAKEE (Final Approach Fix)
• MYRTA (Missed Approach Point)
• RUSSY (Missed Approach Holding Point)
6. Set the HSI course to DTK at each waypoint. The CDI will automatically transition from
the 1.0 to 0.3 nm scale when you are within 2.0 nm of the FAF, and the unit will warn you
if RAIM is not available for your approach.
7. To fly the missed approach procedure, cross the MAP and climb to 3000 feet. For direct
navigation guidance to the missed approach holding point, press
D
followed by
E
after crossing the MAP.
