CL650/Operations Reference/Special Airport Briefing—KASE

As of AIRAC Cycle 2211 there are four options for approaches into KASE. The LOC/DME-E and RNAV (GPS)-F are public approaches and documented in the normal publications. Note: both approaches are in excess of 6° descent angle. However these are V-MDA approaches that do not terminate at the runway (hence Special Approach does not apply).

The intention of these approaches is to obtain suitable conditions to conclude the instrument approach segment and visually maneuver to a suitable position to fly a normal visual landing on runway 15 aided by the Precision Approach Path Indicators (PAPIs) set at 3.5°. In addition neither approach provides Category D circling minima so by necessity the Challenger should not operate into Aspen when the required maneuvering speed exceeds 140 knots.

Operational experience suggests that when the LOC/DME-E or RNAV (GPS)-F are flown to the published minimums the resulting visual maneuvering will be especially challenging and beyond the limit of normal safe operational parameters—conditions that allow visual maneuvering before descending below 12,500 ft allow more conservative maneuvering.

The navigation database supplied by Laminar Research and Navigraph also include non-public, special authorization approaches that permit lower minimums and easier maneuvering. Charts are not available in normal publications for these approaches, so the following information may be useful to assist monitoring the aircraft performance on these approaches. The LOC/DME 15 is recommended for all normal KASE operations. It is strongly recommended not to conduct the RNAV-Z 15 due to lack of available information.

LOC/DME 15

Instrument approach glidepath of 4.55°. The instrument approach intercepts the 3.5° PAPI path at 1.6 nautical miles (nm) from the runway threshold so the Special Approach Supplement does not apply. Do not adjust onto the PAPI profile beyond 5.0 nm DME from IASE. The required flight visibility is 3 nm.

Runway 15—Rejected Landing

Fly overhead runway 15 while executing the initial go-around actions (TOGA, Flaps 20, Gear Up). Beyond runway 15’s departure end, at 14.8 nm DME from DBL VOR (3.5 nm from WIDMI), execute a climbing left turn to heading 300° at 30° angle of bank and a speed not exceeding 160 kts. Remain within 15.3 nm DME from DBL VOR (3.8 nm from WIDMI). Follow the IPKN localizer outbound as per the published missed approach.
