Protecting Your Aircraft Through a UK Winter

A UK winter is hard on aircraft. Short days and quieter schedules mean aircraft sit for longer, and while they wait, frost, rain, wind-blown grime and damp all go to work on the paint, glass and cabin. Good winter aircraft care starts in the autumn, and a little preparation now saves a lot of time and money by spring.

Here are six practical ways to protect a business jet or private aircraft through the colder months.

1. Start the season clean

Dirt holds moisture against the surface. Exhaust residue, insect remains and bird droppings left on the paint over winter can etch it and make the spring clean much harder. A thorough clean before the weather turns means the aircraft starts the season with a clean, dry surface.

If the aircraft is parked where a wet wash isn’t allowed, a dry wash does the same job without hoses or runoff.

2. Add a layer of protection

A polish followed by a sealant, or a longer-lasting ceramic coating, gives water and grime less to grip. Rain beads off, dirt comes away more easily, and the paint underneath stays protected from UV and contamination. If your aircraft lives outside on the apron, this is the single most useful thing you can do before winter.

3. Handle frost and ice carefully

Never scrape frost off the paint or the windscreen. Scraping scratches acrylic windows and paintwork, and the damage is expensive to put right. Use hangar time, covers or approved de-icing methods instead, and always follow your aircraft’s flight manual, your operator’s procedures and your engineer’s advice.

De-icing fluid does an important job, but its residue shouldn’t be left to build up on the airframe. Once it has done its work, have it cleaned off as part of the aircraft’s regular care.

4. Keep damp out of the cabin

An aircraft that sits for weeks can trap moisture inside, which leads to musty smells, mould and stained upholstery. Air the cabin when you can, remove anything damp, and consider a moisture absorber while the aircraft is parked.

A private jet interior clean before winter removes the dirt, crumbs and organic matter that mould feeds on, and leaves leather and carpets in better shape to sit out the colder months.

5. Use covers properly

Well-fitted covers keep off frost, rain and droppings. A loose or dirty cover can do more harm than good, rubbing grit into the paint every time the wind moves it. Make sure covers are clean, properly fitted and dry before they go on, and follow the manufacturer’s guidance for any covers on probes, intakes and other openings.

6. Book your spring clean early

When the weather improves, everyone wants their aircraft cleaned at once. Booking a spring detail now secures a slot before the rush. It can often be timed for when the aircraft is already in a hangar for maintenance, so there’s no extra downtime.

Winter aircraft care: how we can help

We offer pre-winter cleans, polishing, paint protection and interior deep cleans as part of our aircraft cleaning and detailing service. Exterior work needs suitable conditions, so in poor weather we’ll work in a hangar at the FBO or MRO where one is available, or agree a new date with you in good time. Interior work can usually go ahead whatever the weather.

We’re a mobile team based in Essex, covering the London airports and anywhere in the UK. For an idea of pricing, see our guide to aircraft cleaning costs in the UK.
