For flight operations in the Maldives all aircraft are disinfected upon landing after passenger disembarkation prior to the next departure. MACL provides aircraft disinfection and decontamination services for aircraft from seaplanes to wide body jets.
Looking at the domestic aircraft used in flight operations, National airline Maldivian operates using Dash-8 200,300 series aircraft. In the current cabin environment of the Dash-8, air is drawn from the cabin where it is mixed with fresh air before being distributed back to the cabin with filtering. 100% refreshed cabin air can be provided in under 3 minutes. Additionally, Collins Aerospace Systems has introduced Cabin Air Recirculation high-efficiency particulate air (HEPA) filter installation kit for use on the Dash 8 aircraft. The HEPA filter kit mounts inside an aluminum enclosure along with a prefilter and together trap at least 99.97% of the harmful airborne particles that have a diameter of 0.3 micron. These include bacteria, viruses, pollen, dust, mites and other microscopic airborne contaminants in aircraft environmental control systems. This can be installed in the aircraft.
Manta Air and Fly Me operates with ATR 42/72 series aircraft. ATR aircraft systems ensure that the air in the cabin is blown transversally and vertically. It keeps personal overhead ventilation on and pointed down which contributes to further direct the flow up to the exhaust grills at foot level. The cycle allows a quick and total renewal of the cabin volume with fresh air coming exclusively from the outside after only 5 minutes.
