Ceramic Coating at Bern-Belp (LSZB)

What changes at Bern-Belp?

Bern sits at 1,675 ft on a single 1,730 m runway, which keeps traffic light and ramp movements predictable. The General Aviation Center—run by Flughafen Bern AG as Ground Services Bern—handles all business-aviation movements, so there is one contact (+41 31 960 21 31, frequency 131.410) for parking, hangar access, and airside escort. The airport is not slot-coordinated, and customs and immigration operate during aerodrome hours, which simplifies international arrivals.

The elevation means cold-soaked wings in winter and a shorter window between the last de-icing application and take-off; a ceramic-coated surface sheds Type I fluid faster and stays cleaner during the holdover period. The single runway also means every stand is a short taxi from the General Aviation Center hangar, so the aircraft spends less time on the apron before moving inside for the multi-day treatment. Ground Services expects prior permission and a handler briefing if a third-party detailing crew will work airside; the ceramic curing happens entirely in the hangar, so no GPU or external lighting is required on the ramp.

Why apply ceramic coating between legs at this airport?

Bern is six kilometres south-east of the city centre, close enough for same-day meetings but far enough from the main European trunk routes that the airport rarely appears as a fuel stop. That makes it ideal for planned downtime: the aircraft arrives, the crew hotels in Bern, and the jet moves into the General Aviation Center hangar for decontamination, correction, and the two-layer ceramic application. Three to six days later it re-enters service with a finish that will stay cleaner through a winter of de-icing fluid and a summer of high-altitude UV exposure.

The alternative—ceramic coating at a maintenance base—works if heavy checks coincide with the two-to-three-year recoating cycle, but most operators find that the cabin refresh or avionics upgrade runs over schedule and the ceramic work gets pushed to the next window. Booking the treatment as a standalone event at a quiet GA airport means the aircraft is back on the flight deck when promised, and the chief pilot can plan the rest of the quarter around a known return-to-service date.

What does the three-to-six-day process include?

The aircraft enters the hangar and the team begins with a rinseless wash to remove loose contaminants, then applies a clay-bar decontamination to pull embedded particles—brake dust, turbine soot, tree sap, insect residue—out of the paint. That step is not optional: ceramic bonds to the surface it finds, so any contamination trapped underneath will stay there for the next two years.

Once the paint is clean, the team inspects under LED work lights for oxidation, swirl marks, and scratches. Light defects are corrected with a single-stage polish; deeper scratches are noted in the tech log but left alone unless the operator has authorised wet-sanding. The goal is a uniform, defect-free surface before the first ceramic layer goes on.

The ceramic itself is applied in two coats, with a flash-off period between layers. Brightwork—nacelle lips, leading edges, winglets—receives the same treatment, as do the windscreen and cabin windows. The aircraft then cures in the hangar for twelve to twenty-four hours, depending on ambient temperature and humidity. Before release, the team issues a maintenance plan that specifies compatible wash chemistry and a recommended recoating interval, and the warranty document goes into the aircraft file.

How does ceramic coating change the wash schedule?

A ceramic-coated surface is hydrophobic, so water and dissolved contaminants bead and roll off rather than spreading into a film. That means every turnaround wash takes less time: the belly, gear bays, and nacelles rinse cleaner with less scrubbing, and the cheat line and winglets need only a light wipe to remove residue. Over a year, the time saved adds up—fifteen minutes per wash, twenty washes, five hours returned to the schedule.

The coating also resists de-icing fluid, which matters at Bern in winter. Type I fluid sheets off a ceramic surface faster than off bare paint, so the holdover time is slightly longer and the leading edges stay cleaner between applications. The UV resistance is equally useful in summer: a coated finish does not oxidise as quickly at altitude, so the aircraft still looks sharp after a season of high-flight-level legs across the Alps.

The maintenance plan will specify a compatible rinseless wash chemistry and a recommended frequency—usually every two weeks for an aircraft in daily use, longer for a jet that flies once or twice a month. The ceramic does not eliminate washing, but it makes every wash faster and less abrasive, which extends the life of the underlying paint.

Who coordinates with Ground Services and the hangar?

The detailing crew handles all airside coordination, but the operator's flight-department manager or chief pilot should notify Ground Services Bern at least five days before arrival. The notification includes the registration, MTOW, arrival and departure slots, and a note that a third-party crew will be working in the hangar for three to six days. Ground Services will confirm hangar availability, issue airside passes, and arrange an escort if the detailing team needs to move equipment between the apron and the hangar.

Once the aircraft is on the ground, the handling agent marshals it to the stand, and the detailing crew takes over. If the jet is cold-soaked from a high-altitude leg, the team will wait for the wings to reach ambient temperature before moving the aircraft inside; ceramic application over cold metal leads to uneven curing and a shorter service life. Ground Services expects a call thirty minutes before the aircraft is ready to leave the hangar, so they can arrange a tug if needed and update the departure slot.

When should ceramic coating be scheduled?

The ideal moment is immediately after a repaint, when the paint is fully cured and free of defects. The ceramic locks in that fresh finish and protects it from the first de-icing application, the first bug strike, and the first season of UV exposure. If the aircraft has just come out of heavy maintenance with new paint, the ceramic treatment adds two to three years before the next correction and polish cycle.

The second-best moment is after a Complete Detail, when the paint has already been decontaminated, corrected, and polished. The surface is prepared, so the ceramic application takes less time and the results are immediate. The third option is to schedule ceramic recoating every two to three years as a standalone event, regardless of maintenance timing. The coating wears gradually—hydrophobicity decreases, wash times creep back up—but it does not fail suddenly, so the operator has a predictable window to book the work between legs.

Winter in Bern is busy with ski-season charters, so hangar space is tighter between December and March. Spring and autumn offer longer booking windows and consistent hangar temperatures, which makes curing more predictable. Summer works as well, though high-altitude UV exposure after application is not ideal; the coating is fully cured, but the first few weeks determine how well it bonds, so a week of moderate weather after release is better than a week of intense sun.
