220 and its derivatives were thick-sectioned, high-winged, four engined monoplanes from Farman Aviation Works. Based on the push-pull configuration proven by the F. 211, design started in August 1925 and the first flight of the prototype was 220c to f 26 May 1932. 220 prototype, Farman made a number of changes to the design, including a new tail fin, fully enclosing the nose and ventral gunners’ positions, and changing from V-engines to radials.
The first example of this version, dubbed the F. 221 flew in May 1933, and was followed by ten production examples delivered to the Armee de l’Air from June 1936. 222 variant began to enter service with Armee de l’Air in the spring of 1937. Unlike its predecessor, this plane featured a retractable undercarriage.
Twenty-four aircraft were produced with redesigned front fuselages and dihedral added to the outer wing. During World War II these planes were used in leaflet raids over Germany and then night bombing raids during May and June 1940. 222 was involved in a notable operation carried out by French fighter pilot James Denis. On 20 June 1940, realising that the Battle of France was lost, Denis borrowed a Farman F. 222 from an airbase near Saint-Jean-d’Angély. The first prototype was ordered as a long-range mail plane and in October 1937 established a record by flying 621 miles with a 22,046 lb payload. 3 bombers were delivered in May 1940 and participated in night bombing attacks on Germany before being transferred to North Africa in June 1940.
The bombers were subsequently relegated to transport roles, seeing service with both the Vichy regime and the Free French. 224 was a dedicated civil variant able to seat 40 passengers. Six machines were produced for Air France, but were ultimately rejected because the 224 could not maintain altitude on three engines. The aircraft went on to serve in the Armée de l’Air instead with a reduced payload.

Mains electricity by country includes a list of countries and territories, with the plugs, voltages and frequencies they commonly use for providing electrical power to low voltage appliances, equipment, and lighting typically found in homes and offices. Voltage, frequency, and plug type vary, but large regions may use common standards. In some areas, older standards may still exist. The International Electrotechnical Commission publishes a web microsite World Plugs which provides the main source for this page, except where other sources are indicated. Voltages in this article are the nominal single-phase supply voltages, or split-phase supply voltages.

Where a plug does not have a specific letter code assigned to it, then it may be defined by the style sheet number listed in IEC TR 60083. Type F are also available at some hotels. Sockets for British type G plugs are mainly found at some hotels and never in households. NEMA 14-30R and 14-50R receptacles are provided on 240 V circuits for clothes dryers and electric stoves. Schuko or type F plugs are often used for high power appliances.
