Ceramic Coating at St. Gallen-Altenrhein (LSZR)

What changes at St. Gallen-Altenrhein?

Altenrhein sits at 1,306 ft on the southern shore of Lake Constance, a few kilometres from the Austrian, German and Liechtenstein borders. The single hard runway—10/28, with 1,455 metres of take-off run available and ILS CAT I on 10—handles everything from turboprops to the largest business jets that can meet the distance limit. The field is a customs-clearing airport with both Schengen and non-Schengen immigration, so international arrivals and departures clear here without a positioning leg to Zurich.

No slot or PPR allocation is needed for business aviation; you file and go. The handling agent present at the airport is Airport Altenrhein AG Ground Services, which also operates the business aviation terminal at Flughafenstrasse 11. That terminal includes a crew lounge, and the handler monitors 131.505 for ground coordination. Because the airline side is a small passenger terminal with walk-boarding, the apron is quiet and the handler knows when a third-party detailing crew will be working airside.

Lake Constance moderates winter temperatures but raises summer humidity. Paint that has been ceramic-coated sheds the fine dust and pollen that blow off the water and the surrounding farmland, and the hydrophobic layer makes every rinseless wash faster when the aircraft returns from a sequence through wetter northern European fields.

Why does ceramic coating take three to six days?

Paint correction comes first. We clay-bar every panel to lift embedded contamination—brake dust, exhaust soot, de-icing residue, tree sap—then machine-polish to remove oxidation and light scratches. On an ultra-long-range airframe that has been flying for two or three years since the last polish, correction alone can take a full day. We mask all no-touch avionics, pitot probes and static ports before we begin, and we inspect the cheat line and any vinyl graphics to be sure they will survive the process.

Once the paint is corrected, we apply the first ceramic layer and let it flash. The second layer goes on twelve to twenty-four hours later, depending on the product and the hangar temperature. Brightwork—nacelle lips, leading edges, winglets—receives its own ceramic treatment after polishing. Windows get a separate hydrophobic coating. The entire aircraft then cures under stable temperature and humidity for at least another day before we release it.

If the belly or gear bays need decontamination, or if you want the cabin detailed in the same downtime, the calendar stretches toward the six-day end of the range. We coordinate the schedule with your next departure slot so the aircraft is never waiting on the stand longer than necessary.

What does ceramic coating actually protect against?

Ceramic forms a hard, hydrophobic layer over the paint. Water beads and rolls off, carrying dust and light dirt with it. That behaviour cuts the time required for every dry wash or rinseless wash between now and the next full detail. The coating also resists UV radiation, so the paint underneath fades more slowly, and it stands up to the glycol in Type I and Type IV de-icing fluids, which otherwise etch clear coat over a winter season in the Alps.

Industrial fallout—the fine metallic particles that settle on an aircraft parked near a busy apron or downwind of a city—bonds to bare paint but sits on top of ceramic. A single wash removes it before it can stain. The same is true of insect strikes on the leading edges and belly: the ceramic layer releases them more easily during the post-flight wipe-down, so your line crew spends less time scrubbing and more time on the walkaround.

Ceramic does not make the aircraft invincible. It will not fill deep scratches, repair stone chips on the nose, or hide oxidation that was already present. That is why we correct the paint first. What it does do is lock in the result of that correction for two to three years, depending on how many cycles the aircraft flies and where it spends the winter.

How does this fit into a fleet maintenance cycle?

Most flight departments schedule ceramic coating immediately after a repaint, when the clear coat is fresh and needs no correction, or after a complete detail that has already brought the paint back to gloss. If your aircraft has just come out of heavy maintenance with new paint, we skip the correction steps and go straight to surface prep and coating; the whole job then takes three or four days instead of five or six.

If the aircraft is midway through a lease or a charter certificate and the paint is tired but not bad enough to warrant a repaint, ceramic coating after correction will buy you another two or three years of presentable appearance. We document the before-and-after state with photos and a written report, which goes into the tech log and supports the residual-value argument when the lease ends.

For a fleet operating out of a single European base, we can establish a rotating schedule: one airframe every quarter, so that by the end of the year the entire fleet is coated and the first aircraft is ready for its mid-cycle maintenance wash. That approach spreads the downtime and the cost, and it means your crews are always flying at least one aircraft that looks like it just came out of the paint shop.

What happens when the aircraft arrives at Altenrhein for ceramic work?

You file direct to LSZR with no slot or PPR requirement. After landing on runway 10 or 28, ground services will taxi you to the stand and arrange hangar space if it is not already reserved. We coordinate with the handler in advance so that GPU, airside escort and hangar access are waiting when the aircraft blocks in. If your crew is staying in St. Gallen or across the lake in Bregenz, the handler can arrange ground transport; if they are positioning out on a commercial flight, Zurich is an hour by road and Friedrichshafen is twenty minutes across the German border.

Once the aircraft is in the hangar, we photograph the exterior, log any existing damage in the tech log, and begin the decontamination process. The chief pilot or flight-department manager receives a progress update each day, with photos at the end of paint correction and again after the ceramic layers are applied. When curing is complete, we perform a final inspection, hand over the maintenance plan and warranty document, and release the aircraft. If you need a post-ceramic wash at another field within the next month—say, after a dusty positioning leg to southern Europe—the warranty covers a single free wash to prove the coating's behaviour.

Why choose Altenrhein for a multi-day ceramic job?

Altenrhein is uncongested. There are no airline waves to work around, no slot restrictions to force a departure before the coating has cured, and hangar availability is better than at Zurich or Geneva. The field's location at the intersection of four countries makes it a natural staging point for a central-European charter programme or a corporate shuttle that works Germany, Austria and Switzerland in the same week. You bring the aircraft in on a Friday, we work the weekend, and it departs the following Wednesday ready for another month of operations.

The handler is also the airport operator, so coordination is direct. When we need extended hangar time or a specific stand for post-cure inspection, the conversation happens in one phone call. That matters when you are managing a fleet and every day of downtime has a cost. Altenrhein will never be as busy as the major hubs, and for a service that requires three to six days of uninterrupted hangar work, that is exactly the point.
