Autoland - Wikipedia. In aviation, autoland describes a system that fully automates the landing procedure of an aircraft's flight, with the flight crew supervising the process. Such systems enable aircraft to land in weather conditions that would otherwise be dangerous or impossible to operate in.

Description[edit]Autoland systems were designed to make landing possible in visibility too poor to permit any form of visual landing, although they can be used at any level of visibility. They are usually used when visibility is less than 6.

Runway Visual Range and/or in adverse weather conditions, although limitations do apply for most aircraft—for example, for a Boeing 7. They may also include automatic braking to a full stop once the aircraft is on the ground, in conjunction with the autobrake system, and sometimes auto deployment of spoilers and thrust reversers.

Autoland may be used for any suitably approved Instrument Landing System (ILS) or Microwave Landing System (MLS) approach, and is sometimes used to maintain currency of the aircraft and crew, as well as for its main purpose of assisting an aircraft landing in low visibility and/or bad weather. Autoland requires the use of a radar altimeter to determine the aircraft's height above the ground very precisely so as to initiate the landing flare at the correct height (usually about 5. The localizer signal of the ILS may be used for lateral control even after touchdown until the pilot disengages the autopilot. For safety reasons, once autoland is engaged and the ILS signals have been acquired by the autoland system, it will proceed to landing without further intervention, and can be disengaged only by completely disconnecting the autopilot (this prevents accidental disengagement of the autoland system at a critical moment) or by initiating an automatic go- around. At least two and often three independent autopilot systems work in concert to carry out autoland, thus providing redundant protection against failures.

The U.S. National Transportation Safety Board ruled today that the “operational design” of Tesla’s Autopilot played a key role in a 2016 fatal crash that left.

Most autoland systems can operate with a single autopilot in an emergency, but they are only certified when multiple autopilots are available. The autoland system's response rate to external stimuli work very well in conditions of reduced visibility and relatively calm or steady winds, but the purposefully limited response rate means they are not generally smooth in their responses to varying wind shear or gusting wind conditions – i. The first aircraft to be certified to CAT III standards, on 2. December 1. 96. 8,[1] was the Sud Aviation Caravelle, followed by the Hawker- Siddeley HS.

Autoland capability has seen the most rapid adoption in areas and on aircraft that must frequently operate in very poor visibility. Airports troubled by fog on a regular basis are prime candidates for Category III approaches, and including autoland capability on jet airliners helps reduce the likelihood that they will be forced to divert by bad weather. Autoland is highly accurate. In his 1. 95. 9 paper [2] John Charnley, then Superintendent of the UK Royal Aircraft Establishment's (RAE) Blind Landing Experimental Unit (BLEU), concluded a discussion of statistical results by saying that "It is fair to claim, therefore, that not only will the automatic system land the aircraft when the weather prevents the human pilot, it also performs the operation much more precisely". Traditionally, autoland systems have been very expensive, and have been rare on small aircraft.

However, as display technology has developed the addition of a Head Up Display (HUD) allows for a trained pilot to manually fly the aircraft using guidance cues from the flight guidance system. This significantly reduces the cost of operating in very low visibility, and allows aircraft which are not equipped for automatic landings to make a manual landing safely at lower levels of look ahead visibility or runway visual range (RVR).

In 1. 98. 9, Alaska Airlines was the first airline in the world to manually land a passenger- carrying jet (Boeing B7. FAA Category III weather (dense fog) made possible with the Head- Up Guidance System.[3][4]History[edit]Background[edit]Commercial aviation autoland was initially developed in Great Britain, as a result of the frequent occurrence of very low visibility conditions in winter in North- west Europe. These occur particularly when anticyclones are in place over central Europe in November/December/January when temperatures are low, and radiation fog forms easily in relatively stable air. The severity of this type of fog was exacerbated in the late 1. Cities particularly affected included the main [UK] centres, and their airports such as London Heathrow, Gatwick, Manchester, Birmingham and Glasgow, as well as European cities such as Amsterdam, Brussels, Paris, Zurich and Milan.

Visibility at these times could become as low as a few feet (hence the "London fogs" of movie fame) and when combined with the soot created lethal long- persistence smog: these conditions led to the passing of the UK's "Clean Air Act" which banned the burning of smoke- producing fuel. Post 1. 94. 5, the British government had established two state- owned airline corporations – British European Airways (BEA) and British Overseas Airways Corporation (BOAC), which were subsequently to be merged into today's British Airways. BEA's route network focused on airports in the UK and Europe, and hence its services were particularly prone to disruption by these particular conditions. During the immediate post- war period, BEA suffered a number of accidents during approach and landing in poor visibility, which caused it to focus on the problems of how pilots could land safely in such conditions. A major breakthrough came with the recognition that in such low visibility the very limited visual information available (lights and so on) was extraordinarily easy to misinterpret, especially when the requirement to assess it was combined with a requirement to simultaneously fly the aircraft on instruments. This led to the development of what is now widely understood as the "monitored approach" procedure whereby one pilot is assigned the task of accurate instrument flying while the other assesses the visual cues available at decision height, taking control to execute the landing once satisfied that the aircraft is in fact in the correct place and on a safe trajectory for a landing.
