Exterior Dry Wash at Speyer/Ludwigshafen (EDRY)

Why choose a dry wash instead of a water rinse at Speyer/Ludwigshafen?

Water availability and environmental discharge rules vary widely across European regional fields, and a dry wash sidesteps both constraints. At EDRY we bring our own aviation-approved waterless chemistry and microfibre system; no hose connection, no wash-pad booking, no wastewater disposal paperwork. The aircraft stays on stand or moves only as far as the FBO apron at Joachim-Becher-Straße 2.

The second advantage is operational: a dry wash can start as soon as the aircraft is chocked and the APU or GPU is confirmed, with no dependency on a wash bay slot or tug schedule. For flight departments managing tight turnarounds or unexpected diversions into Speyer, that flexibility is the difference between a clean jet and a postponed service. We coordinate directly with Silver Cloud Air—the handling agent present at the airport—so stand allocation and airside escort are arranged in advance.

Finally, the chemistry itself: modern waterless products emulsify contaminants and leave a thin hydrophobic layer that helps the next rain sheet off cleanly, extending the interval between full details. Bug residue and hydraulic mist come off without abrasion, and the process is safe for all OEM paint finishes and decals.

What documentation does Terso provide after an exterior dry wash?

Every exterior dry wash concludes with a digital photo report and a signed work order, both delivered within two hours of service completion. The photo set captures before and after images of each major surface—nose, fuselage sides, belly, wings, empennage, nacelles and landing gear—so your chief pilot or maintenance controller has a visual record of the work performed and the condition on arrival. The images are date- and location-stamped and archived for twelve months.

The work order lists the products used (manufacturer, batch and approval references), the areas cleaned, the start and finish times, and any observations—paint chips, leading-edge erosion, fluid leaks—that warrant maintenance attention. It is written in English, formatted for insertion into your tech log or maintenance-tracking system, and signed by the technician on site. If your operation requires a specific work-order template or additional sign-off fields, send it with the booking and we will use it.

This documentation is especially useful for managed fleets and charter operators whose aircraft move between multiple bases: the photo archive provides continuity when different crews and different maintenance teams are involved, and it supports warranty claims if paint or coating issues appear later.

How do we coordinate a dry wash with the handler at Speyer/Ludwigshafen?

Silver Cloud Air is the handling partner of FSL Flugplatz Speyer/Ludwigshafen GmbH and provides all business-aviation ground services at EDRY, including fuel, slot and PPR organisation, and customs clearance for non-Schengen flights with two hours' notice. When you book an exterior dry wash, we notify Silver Cloud of the service window, the estimated duration and any stand or power requirements. The handler confirms the stand assignment and arranges our airside escort if the aircraft will remain on the apron rather than taxi to the FBO terminal.

If your arrival is an AOG diversion or an unscheduled tech stop, call us as soon as you have an on-block time; we keep a mobile team within ninety minutes of Speyer and can often start the same day. The handler will need your registration, MTOW, fuel order and passenger count as usual; we need only the aircraft type, the requested service and a mobile number for the captain or dispatcher. Once the aircraft is chocked and external power is confirmed, we begin.

One note on timing: EDRY is not slot-coordinated, so there is no ATFM delay to plan around, but the single 1,677-metre runway (16/34) is shared with recreational and training traffic during daylight hours. If your departure slot is tight, let both the handler and Terso know; we will prioritise the upper fuselage and wings so that even if the full belly clean runs over, the visible surfaces are complete before engine start.

What changes at Speyer/Ludwigshafen that affect exterior cleaning?

Speyer/Ludwigshafen sits at 312 feet elevation in the Rhine valley, a low-lying corridor that channels moisture and industrial haze from the surrounding Rhine-Neckar urban region. The Technik Museum Speyer lies immediately north of the field, and the airport markets itself to corporate traffic serving Mannheim, Ludwigshafen and Heidelberg. The single runway, 16/34 at 1,677 metres, accommodates light and midsize business jets comfortably; larger aircraft are less common but do operate in and out for executive charters and special events.

The private FBO terminal operated by Silver Cloud Air includes passenger and crew lounges and flight-preparation rooms at Joachim-Becher-Straße 2, adjacent to the apron. If your aircraft will remain overnight or through a longer ground stop, the terminal apron is the preferred location for exterior work: it is lit, paved and sheltered from the prevailing westerlies that sweep the open field. For short turnarounds, we work on the arrival stand.

Seasonally, the Rhine valley climate is temperate but humid. Spring and autumn bring heavy morning dew and mist that accelerates the buildup of hydraulic film and exhaust residue on the belly and nacelles. Winter frost is infrequent at this elevation, but when it occurs the airfield can arrange de-icing; we do not begin a dry wash on a cold-soaked airframe until surface temperature is above three degrees Celsius, to prevent product crystallisation. Summer afternoons can be warm and still, ideal for rapid drying, though thunderstorm activity occasionally rolls through the valley and forces a pause mid-service. The handler monitors the METAR and will advise if weather is marginal.

What does the dry-wash process look like on the ramp at EDRY?

The technician arrives with a rolling cart of waterless cleaning solution, microfibre applicators, separate polishing cloths and a degreaser concentrate for the belly and gear bays. The aircraft must be chocked, pitot covers and static-port covers in place, and external power connected if cabin access is needed to check that avionics and galley systems are isolated. We do not touch flight-deck panels, but we do verify with the captain or handler that the aircraft is electrically safe before working near radome, antennas and sensor windows.

Work begins at the nose and proceeds aft along one side, then the other: fuselage, wings, winglets (if fitted), empennage and nacelles. Bug strike on the leading edges and radome receives extra dwell time; the waterless product emulsifies the protein without scrubbing. Exhaust soot around the tailpipe and nacelle trailing edges is treated with a separate high-pH cleaner, applied and buffed within sixty seconds to avoid streaking. The belly and main-gear bays are degreased last, using a low-lint cloth and a citrus-based solvent; hydraulic mist and oil weep are common in these areas and require two passes.

Exterior windows—cockpit, cabin and door glass—are cleaned with an ammonia-free formula safe for anti-reflective coatings. Navigation and strobe lights are wiped, and any light brightwork (cheat-line trim, door handles, static dischargers) is polished if time permits. The entire process is no-touch on avionics fairings, angle-of-attack vanes and sensor ports; these are flagged with the handler and left for maintenance if contamination is present.

How often should an aircraft receive a dry wash between full details?

For a business jet in regular service—three to five legs per week—an exterior dry wash every two to four weeks keeps the paint clean and prevents the buildup of contaminants that etch or stain over time. Bug residue is acidic and, if left for more than a few days in warm weather, will bond to the clear coat; hydraulic fluid and engine oil do the same on the belly. A dry wash arrests that process before it becomes a polishing problem.

If the aircraft operates frequently into high-insect environments—summer evening departures from fields near rivers or wetlands, for example—the interval shortens to two weeks. Conversely, if the jet spends most of its time at altitude and rarely flies below flight level 250, a four-week interval is sufficient. The key indicator is the leading edges and the windscreen: when bug strike is visible from ten paces, it is time.

A dry wash is not a substitute for a single-stage polish or a full decontamination and wax, but it is an effective interim service that keeps the aircraft presentable and protects the paint investment. Many fleet operators schedule a dry wash after every five or six flights, a polish every quarter, and a full detail annually. That cadence minimises downtime and spreads the cost across the calendar.
