2.4 Departure Procedures Instrument Departures The current FAA published Departure Procedure for John Wayne Airport requires all aircraft to climb runway heading to 700 and then make a left turn (R01 L) or a right turn (R19R) direct Seal Beach VORTAC. The turns are commenced at an altitude well above the proposed Geneva Commons building therefore not imposing any impact on departing aircraft. The Anaheim Three Departure requires a turn to 330 degrees after takeoff from R01 L. However, the aircraft is not supposed to commence a turn prior to reaching 400 feet above field elevation. Field elevation is 56 feet MSL therefore the aircraft should not turn prior to reaching 456 feet MSL. This far exceeds the minimum altitude required by the FAA TERPS Departure criteria to clear any building within the Geneva Commons area. This is another reason that FAA has provided for a determination of no adverse impact. The CHANNEL ONE, DUUKE ONE and MUSEL SIX Departures all depart to the South from R19R and therefore are not impacted by the proposed buildings. 2.5 Circling vs VFR Considerations A circling approach to either R01 L or R19R is possible with visibilities as low as 1 statute mile and ceilings as low as 600' AGL above the airport. These circling minimums are significantly lower than VFR requirements of 1000' AGL and 3 miles visibility. The FAA circling minimums put the aircraft closer to the ground and buildings in poor weather conditions than operations under VFR. And yet, the FAA has determined that obstruction clearance requirements are safe and that the circling minimums at John Wayne likewise are safe. My evaluation affirms the FAA findings. The proposed Geneva Commons building site is located 6,876 feet (1.3 sm) north of the end of R19R. The proposed building is neither located on the final approach nor in close proximity to the VFR traffic pattern to Runway 19R. The impacts of penetrations are minor compared to other buildings within the airport area. The minimum R19R VFR traffic pattern altitudes are: 1054 MSL for small aircraft, 1554 MSL for turbine aircraft over 12,500 #, (Source: Airnay.com). The minimum R19L VFR traffic pattern altitudes are: Small Single engine aircraft: 854' MSL, Twin engine aircraft: 1054' MSL, Turbine aircraft: 1554' MSL (Source, John Wayne Airport Pilot Information Guide). The proposed building is located 6876' from R19R at an elevation of 287' MSL. Aircraft on a right downwind to R19R already have a 323' MSL building and 321' MSL building in its downwind and /or base turn area (OBS 8 -323 and 7 -321). In addition, most VFR traffic from the North /Northwest will be following the 405 freeway for their base to the r]
