Instrument Approach & Departures
Flabob has an instrument approach procedure (IAP). It is an RNAV (GPS)-A. And because it is a circling approach, it will work for either runway. However, 24 is the calm wind runway.
As you well know, make certain you have the most current Arrival and Departure Procedures with you before arriving or departing. The following is general information for trip planning.
The approach starts at BAYJY intersection (where V186 intersects V363, south of Brackett), and proceeds by three GPS stepdown fixes westerly toward the airport. Minima for Category A airplanes (most of us) is 1860 – 1 1/4. This corresponds to a ceiling of 1,100 feet. The procedure is not available at night. The reason for the high ceiling and the unavailability at night is the hills in both directions.
As an alternative, when the ceiling is 1,000 or higher and the visibility is 1 mile or better at Riverside Municipal, it has long been known that you can file for the ILS – 9 at Riverside, and when you break out at or above 1800 msl, cancel IFR and ask for a special VFR NW bound for Flabob, then fly up the middle of the river until you see Mt. Rubidoux and make a left base for 24. In practice, the new RNAV approach has about the same minima as this maneuver, but for the majority of us lacking an IFR-approved GPS, this should still work.
TAKEOFF MINIMUMS: Rwy 6, std. w/min. climb of 670′ per NM to 4000 or 400-2 w/min. climb of 480′ per NM to 4000 or 2100-3 for climb in visual conditions. Rwy 24, std. w/min. climb of 630′ per NM to 3000 or 800-2¾ w/min. climb of 305′ per NM to 4600 or 2100-3 for climb in visual conditions.
DEPARTURE PROCEDURE: Rwy 6, climb via heading 064° to 4000 then right turn direct PDZ VORTAC, or for climb in visual conditions cross Flabob Airport.
Southwest bound at or above 2700 then via PDZ R-039 to PDZ VORTAC. Rwy 24, climb via heading 244° and PDZ R-031 to PDZ VORTAC, or for climb in visual conditions cross Flabob airport Southwest bound at or above 2700 then via PDZ R-039 to PDZ VORTAC.
All aircraft climb in PDZ VORTAC holding pattern (hold East, right turns, 258° inbound) to cross PDZ VORTAC at or above MEA for direction of flight before proceeding on course.
