CL650/Operations Reference/Special Airport Briefing—LSZA
As of AIRAC Cycle 2211 there are two approaches to LSZA: an IGS to runway 01, and a LOC/DME approach for circling to runway 19. Two circle-to-land to runway 19 tracks are published: Charlie and Foxtrot. The IGS glidepath angle is 6.65°, exceeding the limitations of the Special Approach Supplement. The preferred landing runway is 19, but a greater landing distance is available on runway 01.
This briefing provides a visual approach to runway 01, and circling procedures to runways 01 and 19 via the Foxtrot track to runway 19 and into the visual circuit for runway 01. The circling altitude is 3,600 ft.
The maximum landing weight (MLW) for this procedure is 14,800 kg, due to the need to circle at Flaps 30 and 135 knots. Landing Distances Available (LDA) are 1305 m on runway 01 and 1135 m on runway 19 and may further limit MLW.
The following pilot-defined waypoints are used in these approaches and should be created via INDEX > DATA BASE > PILOT WPT LIST > DEFINE WPT prior to the approach:
| FIX | PLACE BRG / DIST | NOTES |
| LSZA1 | LSZA 042/2.6 | Fly-over: turn to crosswind or final runway 19 |
| LSZA2 | LSZA 000/1.5 | Downwind for runway 01 |
| LSZA3 | LSZA 290/0.3 | Downwind for runway 01 |
| LSZA4 | LSZA 225/2.6 | Fly-over: turn to final runway 01 |
The circling procedures are flown in LNV mode after breaking off from the localizer at D1.7 ILU / ML017. It is recommended to use the secondary flight plan for this so that the missed approach may be flown using the FMS if required prior to circling. This programming should be completed before commencing the approach, and is done via FPLN > SEC FPLN [LSK6L], specifying an origin and destination (LSZA), and adding the following waypoints:
| Runway 01 | ML017 LSZA1 LSZA2 LSZA3 LSZA4 |
| Runway 19 | ML017 LSZA1 |
Both LSZA1 and LSZA4 (if used for an approach to runway 01) should be made fly-over points by overwriting them on the SEC LEGS page ([LSK6L] from the SEC FPLN page) with LSZA1/0 and LSZA4/0, respectively. (A cyan “@” symbol will appear next to them when this is done correctly.) Visual approaches to the appropriate runway should then be added to the secondary flight plan by pressing [LSK4R] on the DEP/ARR page and selecting VISUAL RW01 or RW19. A RWY EXT of 2.0 (nm) should be specified. Finally, from the DEP/ARR page, pressing [LSK6R] will take you to the SEC LEGS page where you will need to delete a discontinuity prior to the RX point. The secondary flight plan should now read:
| Runway 01 | [ORIG] ML017 LSZA1@ LSZA2 LSZA3 LSZA4@ RX01 RW01 |
| Runway 19 | [ORIG] ML017 LSZA1@ RX01 RW01 |
If desired, the final VPA from RX01 to RW01 can be adjusted to 4.17° by entering 4.17 and pressing the right-side LSK next to the RW waypoint.
Visual Approach Straight-In Runway 01
In visual meteorological conditions (VMC) at SRN, and greater than 5,000 m visibility, proceed via SRN 335/14 to a 2.0 nm final for runway 01, with a VPA of 4.17° from SRN 335/14 to the threshold.
LOC/DME 01 Initial Approach for Runways 01 and 19
The instrument approach glidepath angle is 4.4°, however this path is not intended to guide the aircraft to the runway, but rather to a point where a visual or circling procedure can be carried out. As such the limitations in the Special Approach Supplement are not relevant. The required flight visibility is 5,000 m, minimum ceiling is 3,600 ft MSL (2,700 ft AAL) and the procedure is authorized during the day only. Speed limits are 135 knots for circling, and 130 knots for the final approach.
Configure the aircraft to Flaps 30 and 150 knots at 5,800 ft prior to PINIK. Turning onto the final approach course of 17°, descend in LOC and VS modes to be level at 3,600 ft by ML017, monitoring the step-down altitudes as per the chart. A descent rate of 1,000 feet per minute (fpm) should be sufficient. If not visual with the airfield by 3,600 ft fly the published missed approach via D0.7 ILU to PINIK, adhering to the charted speed limitation of 150 knots.
If not flying the missed approach, activate the secondary flight plan and switch to LNV mode prior to D1.7 ILU / ML017. Slow to 135 knots immediately after ML017.
Circle-to-Land Runway 19
Between ML017 and LSZA1, configure for landing with Flaps 45 and Gear Down. Overflying LSZA1, descend in VS mode at 1,300 fpm turning left to a heading of 180°. Expect a GPWS terrain warning during this turn. Slow to the final approach speed and intercept the final approach track for a visual approach at 4.17° on the PAPI to runway 19.
Runway 19—Rejected Landing
Fly overhead runway 19 while executing the initial go-around actions (TOGA, Flaps 20, Gear Up). Beyond runway 19’s departure end, fly heading 197° until passing 4,100 ft, and proceed directly to PINIK at 6,000 ft. Note: this missed approach procedure requires a minimum climb gradient of 10.8%.
Circle-to-Land Runway 01
After ML017, continue over LSZA1 and via LSZA2 and LSZA3. Inhibit the TAWS glideslope alerts to prevent spurious warnings while on final for runway 01 below the IGS glidepath.
Between LSZA3 and LSZA4, configure for landing with Flaps 45 and Gear Down. Overflying LSZA4, descend in VS mode at 1,300 fpm turning left to a heading of 17°. Slow to final approach speed, and make a visual approach at 4.17° to runway 01, using the closer of two PAPIs. The localizer can be used as an aid for lateral guidance.
Runway 01—Rejected Landing
Fly the LOC/DME 01 published missed approach, which is initially to D0.7 ILU (north of the DME) then a climbing right turn with a minimum bank of 25° at no more than 150 knots.
