The lavatory on an aircraft refers to a small room with a sink and toilet. Smaller aircrafts designed for short commutes that carry less than four people don’t contain a lavatory. However, airliners and jets used for charters contain at least one private jet toilet and sink, if not more.
The Different Types
The first private jet toilet to appear on the market included chemical toilet water with the recirculated electric flush feature. However, this style was expensive to maintain and not very sanitary.
Modern lavatories are much better equipped for use during flight than the previous version. They consist of the vacuum flush technology that eliminates waste from the basin quickly and efficiently. This style was first patented in 1975, and most aircraft have switched to this style of lavatory.
The Different Fixtures
Contained within aircraft lavatories are a variety of different fixtures. Some of the most common types include:
- Call buttons
- Electrical outlets
- Soap and hand sanitizer dispensers
- Toilet paper dispensers
- Towel racks
- Paper towel dispensers
- Garbage cans
- Change tables
Servicing the Lavatory
If an aircraft is outfitted with a lavatory, the lavatory tanks will need to be emptied after each flight. Agents specifically tasked with this job use either a small lavatory truck or a larger sewage tank to empty any waste.
