37-398: The aircraft was first publicly introduced on 11 May 2016, and first flew on 10 April 2018. The two seater is designed for the flight training market with a single tractor electric motor powered by Lithium-ion batteries . The design was originally developed by Bye Aerospace subsidiary Aero Electric Aircraft Corporation (AEAC). Arion Aircraft of Shelbyville, Tennessee constructed

74-629: A 3.5 hour duration. The eFlyer 2 features a cantilever low-wing , a two-seat side-by-side configuration enclosed cockpit under a bubble canopy , fixed tricycle landing gear and a single electric motor in tractor configuration powered by up to six Lithium-ion battery packs. The design has a gross weight of 1,900 lb (860 kg) and is made from composite material , primarily carbon fibre . The cockpit employs an iPad used for cockpit instrumentation display, including motor, battery and aircraft systems. The aircraft connects to Redbird Flight Simulations ' Sidekick system, which wirelessly tracks

111-500: A 4.2 hour endurance. The eFlyer 2 first flew on 10 April 2018. AEAC and Bye Aerospace merged in 2018 and Bye Aerospace took over the project. Development of the four-seater should follow completion of the smaller eFlyer 2, the certification of which is forecast to cost US$ 25 million. Bye had received 220 orders for the two models by October 2018. By January 2019, Subaru and SBI Investment invested in Bye Aerospace to advance

148-561: A new allocation granted – in most cases this is from the new country's new ITU allocation, but neither is it uncommon for the new country to be allocated a subset of their former colonial power's allocation. For example, after partition in 1947, India retained the VT designation it had received as part of the British Empire's Vx series allocation, while Pakistan adopted the AP designation from

185-565: A number suffix rather than letters, like the United States (N), South Korea (HL), and Japan (JA), the prefix and suffix are connected without a dash. Aircraft flying privately usually use their registration as their radio callsign , but many aircraft flying in commercial operations (especially charter, cargo, and airlines) use the ICAO airline designator or a company callsign. Some countries will permit an aircraft that will not be flown into

222-462: A press release officially announced the initiation of building eFlyer 2 serial #00001 at the Bye Aerospace facility in Centennial, Colorado. See: Bye Aerospace Begins Initial Build of First eFlyer 2 The aircraft is intended to be certified under FAR 23 and supplied as a complete ready-to-fly-aircraft. It has been designed specifically for the flight training market and is projected to have

259-720: A single letter prefix. Smaller countries had to share a single letter prefix, but were allocated exclusive use of the first letter of the suffix. This was modified by agreement by the International Bureau at Berne and published on April 23, 1913. Although initial allocations were not specifically for aircraft but for any radio user, the International Air Navigation Convention held in Paris in 1919 ( Paris Convention of 1919 ) made allocations specifically for aircraft registrations, based on

296-424: A time. The NAA allocates a unique alphanumeric string to identify the aircraft, which also indicates the nationality (i.e., country of registration ) of the aircraft, and provides a legal document called a Certificate of Registration , one of the documents which must be carried when the aircraft is in operation. The registration identifier must be displayed prominently on the aircraft. Most countries also require

333-469: Is a code unique to a single aircraft, required by international convention to be marked on the exterior of every civil aircraft. The registration indicates the aircraft's country of registration, and functions much like an automobile license plate or a ship registration. This code must also appear in its Certificate of Registration, issued by the relevant civil aviation authority (CAA). An aircraft can only have one registration, in one jurisdiction, though it

370-666: Is changeable over the life of the aircraft. In accordance with the Convention on International Civil Aviation (also known as the Chicago Convention), all civil aircraft must be registered with a civil aviation authority (CAA) using procedures set by each country. Every country, even those not party to the Chicago Convention, has an NAA whose functions include the registration of civil aircraft . An aircraft can only be registered once, in one jurisdiction, at

407-788: Is only one stage in the development of an aircraft type. Unless the type is a pure research aircraft (such as the X-15 ), the aircraft must be tested extensively to ensure that it delivers the desired performance with an acceptable margin of safety. In the case of civilian aircraft, a new type must be certified by a governing agency (such as the Federal Aviation Administration in the United States) before it can enter operation. An incomplete list of maiden flights of notable aircraft types, organized by date, follows. Aircraft registration An aircraft registration

444-559: Is projected to have hourly operating costs one-sixth of a piston-powered Cessna 172. The Safran motor announced in November 2020 will be from the ENGINeUS 100 line. By February 2019, one example, the prototype, had been registered in the United States with the Federal Aviation Administration . By December 2018 the company had 220 deposits, split evenly between the eFlyer 2 and eFlyer 4, growing to 298 by April 2019. In December 2020,

481-618: The Special Administrative Regions of the People's Republic of China , Hong Kong and Macau , both of which were returned to PRC control from Britain in 1997 and Portugal in 1999 respectively. Hong Kong's prefix of VR-H and Macau's of CS-M, both subdivisions of their colonial powers' allocations, were replaced by China's B- prefix without the registration mark being extended, leaving aircraft from both SARs with registration marks of only four characters, as opposed to

518-425: The 1913 callsign list. The agreement stipulated that the nationality marks were to be followed by a hyphen then a group of four letters that must include a vowel (and for the convention Y was considered to be a vowel). This system operated until the adoption of the revised system in 1928. The International Radiotelegraph Convention at Washington in 1927 revised the list of markings. These were adopted from 1928 and are

555-660: The Ryan NYP aircraft flown by Charles Lindbergh as the Spirit of St. Louis was registered in the experimental category. There is a unique overlap in the United States with aircraft having a single number followed by two letters and radio call signs issued by the Federal Communications Commission to Amateur Radio operators holding the Amateur Extra class license. For example, N4YZ is, on

592-618: The United Kingdom) either because of personal or political reasons, or because they fear spurious lawsuits and potential arrest of the aircraft. The first use of aircraft registrations was based on the radio callsigns allocated at the London International Radiotelegraphic Conference in 1913. The format was a single letter prefix followed by four other letters (like A-BCDE). The major nations operating aircraft at that time were allocated

629-475: The United States Department of Homeland Security) are assigned civil registrations. Although each aircraft registration identifier is unique, some countries allow it to be re-used when the aircraft has been sold, destroyed or retired. For example, N3794N is assigned to a Mooney M20F . It had been previously assigned to a Beechcraft Bonanza (specifically, the aircraft in which Buddy Holly

666-404: The aircraft to be registered in the carrier's home country (either because it does not have sufficient regulation governing civil aviation , or because it feels the courts in that country would not cooperate fully if it needed to enforce any security interest over the aircraft), and the carrier is reluctant to have the aircraft registered in the financier's jurisdiction (often the United States or

703-522: The airspace of another country to display the registration with the country prefix omitted - for example, gliders registered in Australia commonly display only the three-letter unique mark, without the "VH-" national prefix. Some countries also operate a separate registry system, or use a separate group of unique marks, for gliders, ultralights, and/or other less-common types of aircraft. For example, Germany and Switzerland both use lettered suffixes (in

740-617: The basis of the currently used registrations. The markings have been amended and added to over the years, and the allocations and standards have since 1947 been managed by the International Civil Aviation Organization (ICAO). Article 20 of the Convention on International Civil Aviation (Chicago Convention), signed in 1944, requires that all aircraft engaged in international air navigation bears its appropriate nationality and registration marks. Upon

777-574: The change, that Bye Aerospace was “… unable to reach a mutual commercial proposition…” with Siemens/Rolls-Royce. At AirVenture in July 2021 George Bye of Bye Aerospace stated that the eFlyer 2 will be certified in late 2022 or early 2023 with a target price of US$ 489,000. A Bye Aerospace press release in January 2023 announced that the eFlyer 2 “…has reached FAA Approval of its G-2 “Means of Compliance for Certification” issue paper.” In September 2024,

814-521: The combinations that could be used: An older aircraft (registered before 31 December 1948) may have a second letter in its identifier, identifying the category of aircraft. This additional letter is not actually part of the aircraft identification (e.g. NC12345 is the same registration as N12345). Aircraft category letters have not been included on any registration numbers issued since 1 January 1949, but they still appear on antique aircraft for authenticity purposes. The categories were: For example, N-X-211,

888-533: The completion of the necessary procedures, the aircraft receives its unique "registration", which must be displayed prominently on the aircraft. Annex 7 to the Chicago Convention describes the definitions, location, and measurement of nationality and registration marks. The aircraft registration is made up of a prefix selected from the country's callsign prefix allocated by the International Telecommunication Union (ITU) (making

925-402: The eFlyer 2 certification. On 8 February 2019 the eFlyer 2 flew for the first time in its intended production configuration, including with a Siemens SP70D electric motor. FAA Part 23 Certification was planned for 2020, with Siemens taking an active part. In November 2020 it was announced that the motor supplier would instead be Safran . In an email to AOPA, George Bye indicated the reason for

The previously-used 57 lb (26 kg) Siemens SP70D had a takeoff rating of 90 kW (120 hp) and 70 kW (94 hp) continuous. Utah-based Electric Power Systems provides the 92-kWh energy storage including battery modules, management and distribution. The 138 kn (256 km/h) cruise aircraft

999-480: The form D-xxxx and HB-xxx respectively) for most forms of flight-craft but numbers (D-nnnn and HB-nnn) for unpowered gliders. Many other nations register gliders in subgroups beginning with the letter G, such as Norway with LN-Gxx and New Zealand with ZK-Gxx. In the United States , the registration number is commonly referred to as an "N" number, because all aircraft registered there have a number starting with

1036-483: The ground under its own power. The same term is also used for the first launch of rockets . In the early days of aviation it could be dangerous, because the exact handling characteristics of the aircraft were generally unknown. The maiden flight of a new type is almost invariably flown by a highly experienced test pilot . Maiden flights are usually accompanied by a chase plane , to verify items like altitude , airspeed , and general airworthiness . A maiden flight

1073-419: The letter N. An alphanumeric system is used because of the large numbers of aircraft registered in the United States. An N-number begins with a run of one or more numeric digits, may end with one or two alphabetic letters, may only consist of one to five characters in total, and must start with a digit other than zero. In addition, N-numbers may not contain the letters I or O , due to their similarities with

1110-480: The newly allocated ITU callsigns APA-ASZ. When this happens it is usually the case that aircraft will be re-registered into the new series retaining as much of the suffix as is possible. For example, when in 1929 the British Dominions at the time established their own aircraft registers, marks were reallocated as follows: Two oddities created by this reallocation process are the current formats used by

1147-405: The numerals 1 and 0 . Each alphabetic letter in the suffix can have one of 24 discrete values, while each numeric digit can be one of 10, except the first, which can take on only one of nine values. This yields a total of 915,399 possible registration numbers in the namespace , though certain combinations are reserved either for government use or for other special purposes. The following are

Since an aircraft registration number is also used as its call sign, this means that two unrelated radio stations can have the same call sign. The impact of decolonisation and independence on aircraft registration schemes has varied from place to place. Most countries, upon independence, have had

When painted on the aircraft's fuselage, the prefix and suffix are usually separated by a dash (for example, YR-BMA). When entered in a flight plan , the dash is omitted (for example, YRBMA). In some countries that use

This can be because the aircraft changes ownership, jurisdiction of registration, or in some cases for vanity reasons. Most often, aircraft are registered in the jurisdiction in which the carrier is resident or based, and may enjoy preferential rights or privileges as a flag carrier for international operations. Carriers in emerging markets may be required to register aircraft in an offshore jurisdiction where they are leased or purchased but financed by banks in major onshore financial centres. The financing institution may be reluctant to allow
