Aircraft spotting or plane spotting is the observation, photographing, and logging of the registration numbers of aircraft, which includes gliders, balloons, airships, helicopters, and microlights.

History and evolution

Aviation enthusiasts have been watching airplanes and other aircraft ever since they were invented. However, plane spotting was not considered a distinct hobby until the second half of the 20th century.

The development of technology and global resources enabled a revolution in spotting. Point and shoot cameras, DSLRs & walkie talkies significantly changed the hobby. With the help of the internet, websites, such as FlightAware, have made it possible for spotters to track and locate specific aircraft from all across the world. Websites, such as Airliners.net, allow spotters to upload their shots or see pictures of aircraft spotted by other people from all over the world.

Techniques

The high engine position on this USAF A-10 Thunderbolt II is an easily observed distinguishing feature of this aircraft.

When spotting aircraft, observers generally notice the key attributes of an aircraft, such as a distinctive noise from its engine or the number of vapour trails it is leaving. Observers assess the size of the aircraft and the number, type and position of its engines. Another distinctive attribute is the position of wings relative to the fuselage and the degree to which they are swept rearwards. The wings may be above the fuselage, below it, or fixed at midpoint. The number of wings indicate whether it is a monoplane, biplane, or triplane. The position of the tailplane relative to the fin(s) and the shape of the fin are other attributes. The configuration of the landing gear can be distinctive, as well.^[1]

Other features include the speed, cockpit placement, colour scheme or special equipment that changes the silhouette of the aircraft. Taken together these traits will enable the identification of an aircraft. If the observer is familiar with the airfield being used by the aircraft and its normal traffic patterns, he or she is more likely to leap quickly to a decision about the aircraft's identity - they may have seen the same type of aircraft from the same angle many times. This is particularly prevalent if the aircraft spotter is spotting commercial aircraft, operated by airlines that have a limited fleet.

Spotters and photographers enjoy seeing aircraft in special colour schemes. This is a Boeing 747-400 of Malaysia Airlines

Spotters use equipment such as ADS-B decoders to track the movements of aircraft. The two most famous devices used are the AirNav Systems RadarBox and Kinetic Avionics SBS series. Both of them read and process the radar data and show the movements on a computer screen. Most of the decoders also allow the exporting of logs from a certain route or airport.^[2]

Spotting styles

Some spotters will note and compile the markings, a national insignia or airline livery or logo, a squadron badge or code letters in the case of a military aircraft. Published manuals allow more information to be deduced, such as the delivery date or the manufacturer's construction number. Camouflage markings differ, depending on the surroundings in which that aircraft is expected to operate.

In general, most spotters attempt to see as many aircraft of a given type, a particular airline, or a particular subset of aircraft such as business jets, commercial airliners, military and/or general aviation aircraft. Some spotters attempt to see every airframe and are known as "frame spotters." Others are keen to see every registration worn by each aircraft.

Ancillary activities might include listening-in to air traffic control transmissions (using radio scanners, where that is legal), liaising with other "spotters" to clear up uncertainties as to what aircraft have been seen at specific times or in particular places. Several internet mailing list groups have been formed to help communicate aircraft seen at airports, queries and anomalies. These groups can cater to certain regions, certain aircraft types, or may appeal to a wider audience. Many of these groups originated from the original Oxford.vax group which pioneered this type of communication. The result is that information on aircraft movements can be delivered worldwide in a real-time fashion to spotters.

The hobbyist might travel long distances to visit different airports, to see an unusual aircraft, or to view the remains of aircraft withdrawn from use. Some aircraft may be placed in the care of museums (see Aviation archaeology) - or perhaps be cannibalized in order to repair a similar aircraft already preserved.

Aircraft registrations can be found in books, with online resources, or in monthly magazines from enthusiast groups. Most spotters maintained books of different aircraft fleets and would underline or check each aircraft seen. Each year, a revised version of the books would be published and the spotter would need to re-underline every aircraft seen. With the development of commercial aircraft databases spotters were finally able to record their sightings in an electronic database and produce reports that emulated the underlined books.

During hostilities

During World War II and the subsequent Cold War some countries encouraged their citizens to become "plane spotters" in an "observation corps" or similar public body for reasons of public security. Britain had the Royal Observer Corps which operated between 1925 and 1995. A journal called The Aeroplane Spotter was published in January 1940. The publication included a glossary that was refined in 2010 and published online.^[3]

Air shows

Air shows usually draw large numbers of spotters as it is a chance to enter airfields and air bases worldwide that are usually closed to the public and to see displayed aircraft at close range.

Legal ramifications

The legal repercussions of the hobby were dramatically shown in November 2001 when fourteen aircraft spotters (twelve British, two Dutch) were arrested by Greek police after being observed at an open day at the Greek Air Force base at Kalamata. They were charged with espionage, and faced a possible 20-year prison sentence if found guilty. After being held for six weeks, they were eventually released on £9,000 bail, and the charges reduced to the misdemeanor charge of illegal information collection. Confident of their innocence they returned for their trial in April 2002 and were stunned to be found guilty, with eight of the group sentenced to three years, the rest for one year. At their appeal a year later all were acquitted.^[4][5][6]

Fight against terrorism

In the wake of the targeting of airports by terrorists, enthusiasts' organizations and police in the UK have cooperated in creating a code of conduct for plane spotters. By asking enthusiasts to contact police if spotters believe they see or hear something suspicious, this is an attempt to allow enthusiasts to continue their hobby while increasing security around airports.^[7] Birmingham and Stansted pioneered this approach in England and prior to the 2012 London Olympics, RAF Northolt introduced a Flightwatch scheme based on the same cooperative principles. These changes are also being made abroad in countries like Australia, where aviation enthusiasts are reporting suspicious or malice actions to police.

The organization of such groups has now been echoed in parts of North America. For example, the Bensenville Illinois Police Department have sponsored an Airport Watch group at the Chicago O'Hare Airport. Members are issued identification cards and given training to accurately record and report unusual activities around the airport perimeter (members are not permitted airside). Meetings are attended and supported by the FBI, Chicago Department of Aviation and the TSA who also provide regular training to group members. The Bensenville program was modeled on similar programs in Toronto, Ottawa and Minneapolis.

Extraordinary rendition

Following the events of 9/11, information collected by planespotters helped uncover what is known as extraordinary rendition by the CIA. Information on unusual movements of rendition aircraft provided data which led first to news reports and then to a number of governmental and inter-governmental investigations.^[8]
