Vayudoot
Vayudoot ( hi, वायुदूत, Vāyudūt, messenger who rides on the wind) was a regional airline in India established on 20 January 1981 as a joint-venture between the two state-owned carriers, Indian Airlines and Air India. The airline was headquartered at New Delhi's Safdarjung Airport. The airline was originally conceived to serve the Northeastern region of India. The regional hub for the Northeast Region was Calcutta (Kolkata), and the airline built up operations to close to 30 destinations in this challenging area. Many of the airfields saw the resumption civil flights and fixed-wing aircraft after a gap of many decades. The airline consistently lost money since its formation due to low occupancy. The government, struggling to find a solution to Vayudoot's continuing financial problems, considered both closure and privatisation as options as the carrier's route and fleet structure made the operation unprofitable.

Fokker F27
The Fokker F27 Friendship is a turboprop airliner developed and manufactured by the Dutch aircraft manufacturer Fokker. It is the most numerous post-war aircraft manufactured in the Netherlands; the F27 was also one of the most successful European airliners of its era. The F27 was developed during the early 1950s with the intent of producing a capable successor to the earlier piston engine-powered airliners that had become commonplace on the market, such as the Douglas DC-3. A key innovation of the F27 was the adoption of the Rolls-Royce Dart turboprop engine, which produced substantially less vibration and noise which provided improved conditions for passengers; another major comfort feature was cabin pressurisation. Innovative manufacturing techniques were also employed in the aircraft's construction. On 24 November 1955, the F27 made its maiden flight; on 19 November 1958, the type was introduced to revenue service. Shortly after its introduction, the F27 was recognised a ...

HS-748
The Hawker Siddeley HS 748 is a medium-sized turboprop airliner originally designed and initially produced by the British aircraft manufacturer Avro. It was the last aircraft to be developed by Avro prior to its absorption by Hawker Siddeley. The HS 748 was developed during the late 1950s as a move to re-orientate the company towards the civil and export markets. Powered by the popular Rolls-Royce Dart turboprop engine, it was specifically designed as a modern feederliner to act as a replacement for the aging Douglas DC-3s then in widespread service. Originally intended to seat a smaller number of passengers, market research indicated that a seating capacity of around 40 passengers would be optimal for the type. As a means to differentiate the new airliner from competitors, it was designed to possess a high level of performance, including its short takeoff and landing (STOL) capabilities and overall ruggedness. First flying on 24 June 1960, the series 1 HS 748 entered revenue s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Radio Navigation
Radio navigation or radionavigation is the application of radio frequencies to determine a position of an object on the Earth, either the vessel or an obstruction. Like radiolocation, it is a type of radiodetermination. The basic principles are measurements from/to electric beacons, especially * Angular directions, e.g. by bearing, radio phases or interferometry, * Distances, e.g. ranging by measurement of time of flight between one transmitter and multiple receivers or vice versa, * Distance ''differences'' by measurement of times of arrival of signals from one transmitter to multiple receivers or vice versa * Partly also velocity, e.g. by means of radio Doppler shift. Combinations of these measurement principles also are important—e.g., many radars measure range and azimuth of a target. Bearing-measurement systems These systems used some form of directional radio antenna to determine the location of a broadcast station on the ground. Conventional navigation techniques a ...
