Aircraft maintenance and storage

PROTECTING AIRCRAFT
DURING STORAGE AND MAINTENANCE

Aircraft are extremely expensive pieces of kit, packed with complex systems and technologies. They move through extremes of weather and climate, but are expected to function without fault to complete their tasks – be they military or civilian. Servicing and storing them under controlled-humidity conditions pays off in terms of greater reliability, faster turnarounds and lower maintenance costs.

Controlled humidity means
less risk of operational glitches

Humidity challenges for aircraft maintenance and storage facilities

Aircraft encounter a vast range of weather, temperature and air conditions in flight, while taxiing and when inside service and maintenance facilities. Their structures feature lots of different materials, surfaces and cavities, and different parts of the plane are at very different temperatures at the same time.

All this adds up to ideal conditions for the formation of condensation, and the corrosion, downtime and maintenance costs that result from this.

Traditional stop-gaps like heating, fans and ventilation are simply incapable of dealing with the many problems caused by uncontrolled humidity and condensation. Replacing one body of air plagued by uncontrolled humidity with another – with just as little control – doesn’t make the problem go away.

Eliminating the problem

Temperature differences between hot or cold materials and the surrounding air result in pretty-much-ideal conditions for corrosion on metal aircraft parts as well as readiness-impacting glitches in both mechanicals and electronics.

In commercial aviation, aircraft only earn revenue when they’re in service. For military operators, mission availability and force effectiveness depend on the required number of aircraft being serviceable at the right time.

In addition, military operations now often involve increasing emphasis on expeditionary, multi-force deployments – which can mean maintenance work has to be carried out in less-than-ideal conditions in unpredictable, extreme environments as well as in temporary structures.

You can notch up a whole series of practical, cost-saving benefits by controlling the point at which the water vapour in the air inside your hangar or maintenance facility condenses (the dew point), so such condensation problems simply cannot arise. Bringing the relative humidity below 65% at 20oC – and keeping it there – completely does away with any condensation problems you may be encountering in your organisation’s aircraft maintenance setup.

Cotes dehumidification systems aim to reduce downtime and delays from your operating equations, and to reduce the duration and costs of whatever maintenance work needs to be done.
