Clinton / Bleibler Ranch (CBR4), BC

The Clinton / Bleibler Ranch (CBR4) GNSS project was interesting for a number of reasons. The Bleibler Ranch runway is on private land and was previously unregistered. In order to qualify for an instrument approach that can be flown by a private pilot the approach must be published in the Canada Air Pilot (CAP). An according to Transport Canada regulations, any aerodrome with approach that is to be published in the CAP must meet at least the equivalent aerodrome obstacle limitation surface (OLS) clearance standards contained in AC 301-001 Table 2. Direct Approach assisted the client to have a survey completed of the aerodrome’s approach and transitional surfaces to determine any OLS penetrations. The items that were subsequently found as violating those surfaces were then cleared.

 Once the OLS was determined and the non-instrument standards for the appropriate wingspan category complied with, the aerodrome was registered with TransportCanadafor publication in the Canada Flight Supplement (CFS).

 The new RNAV (GNSS) approach was designed to transition the aircraft from the nearby airways to the east for a simple and effective straight-in approach to Runway 29. The approach minima permit final descent down to just above 500 ft Height Above Aerodrome (HAA), which is the lowest permitted for a Non-instrument category aerodrome.

 The new IGSIT RNAV (GNSS) departure will permit a “1/2” type route departure off both Runway 11 and Runway 29 transitioning onto V325 at IGSIT which is a new waypoint north of the current Ashcroft NDB.

 The approach and departures were successful flight checked on April 8th 2011 by Direct Approach and are now being submitted for publication in the CAP.
