Current Minimum Standards
Lavatories per passenger provided aboard aircraft vary considerably from airline to airline and aircraft to aircraft. On board North American aircraft, including low-cost, charter, and scheduled service airline carriers, the normally accepted minimum ratio of lavatories to passengers is approximately one lavatory for every 50 passengers. However, in premium cabin and business cabins, passengers may have access to multiple lavatories reserved primarily for their use. These ratios of lavatories to passengers vary considerably, depending upon which airline is being used with some first class passengers having one lavatory for every 12 passengers. Additionally, many of the larger long-haul airlines elect to equip their aircraft with larger lavatories for this particular group of passengers willing to pay higher fares.
Smaller commuter aircraft and regional aircraft designed for short-haul flights may not be equipped with lavatories. Recently, many regional airlines in North America have commenced the trend of eliminating the refilling of hand-washing basin potable water tanks in order to reduce weight and reduce labor service costs, thus generating increased airline profits derived through added fuel savings due to reduction of aircraft weight and employee labor expenses. To facilitate sanitation, disinfectant hand-wipes are provided.

Famous quotes containing the words current, minimum and/or standards:
“It is not however, adulthood itself, but parenthood that forms the glass shroud of memory. For there is an interesting quirk in the memory of women. At 30, women see their adolescence quite clearly. At 30 a woman’s adolescence remains a facet fitting into her current self.... At 40, however, memories of adolescence are blurred. Women of this age look much more to their earlier childhood for memories of themselves and of their mothers. This links up to her typical parenting phase.”
—Terri Apter (20th century)
“There are ... two minimum conditions necessary and sufficient for the existence of a legal system. On the one hand those rules of behavior which are valid according to the system’s ultimate criteria of validity must be generally obeyed, and on the other hand, its rules of recognition specifying the criteria of legal validity and its rules of change and adjudication must be effectively accepted as common public standards of official behavior by its officials.”
—H.L.A. (Herbert Lionel Adolphus)
“Measured by any standard known to science—by horse-power, calories, volts, mass in any shape,—the tension and vibration and volume and so-called progression of society were full a thousand times greater in 1900 than in 1800;Mthe force had doubled ten times over, and the speed, when measured by electrical standards as in telegraphy, approached infinity, and had annihilated both space and time. No law of material movement applied to it.”
—Henry Brooks Adams (1838–1918)
