Airworthiness Requirements

Filippo De Florio , in Airworthiness (Second Edition), 2011

4.3.48 General remarks

The standards dealing with the same products 14 take been put in sequence in the to a higher place list. The list shows the existence of operational standards in addition to the product type-certification standards. These operational standards contain airworthiness requirements that influence the aircraft configuration in relation to their particular operations. xv

A JAR/FAR 23 aeroplane, for example, can obtain a blazon document with the installation (as flight and navigation instruments) of an airspeed indicator, an altimeter, and a magnetic management indicator only. However, to obtain a certificate of airworthiness (the document that authorizes the flying), other instruments and equipment that depend on the item type of operation (e.grand., tourism, aerial piece of work) and on the flying weather [Visual Flight Rules (VFR), Instrumental Flight Rules (IFR), dark flying, etc.] must exist installed as prescribed by the operational rules.

Furthermore, the environmental standards such as FAR 34 and JAR/FAR 36 must be considered. For the FAA and EASA, compliance with the environmental protection requirements is part of the type certification. 16

The JAA requirements were adopted by the JAA Member States, the EASA requirements are now used by the Eu Fellow member States, and the FAA regulations are used in the United States 17 (Canada has almost equivalent rules).

Nevertheless, the manufacturing companies wanting to sell their products on both sides of the Atlantic must perform a double certification, with a substantial increase in costs, peculiarly when the standards are dissimilar. For many years, the transport aeroplane industry has been penalized because the contents of JAR 25 and FAR 25 were not equivalent (even including the same paragraph numbering). JAR 25 originated under a potent English influence, with philosophies borrowed from BCAR Department D. It is as well because of manufacturer'south complaints that, for many years at present, the JAA and FAA have carried out a harmonization procedure that is well advanced, but not nevertheless totally achieved. The situation is improve for JAR/FAR 23 aeroplane standards and for the JAR/FAR 27 and 29 rotorcraft 18 standards, because these JAR requirements were produced with the cooperation of the FAA, with the common will of fugitive the situation that has penalized transport aeroplanes: these standards are now nigh harmonized.

Nosotros will run across in the subsequent chapters how it is possible to minimize the burden related to the acceptance of certifications made by dissimilar government.

System safety and blow prevention

Tommaso Sgobba , ... Stephanie Barr , in Space Prophylactic and Human Performance, 2018

8.six.one.2 Re-entry Traffic Safety

Flight limitations in proximity of space flying operations were first issued in 1964 to support NASA's Gemini and Apollo recovery operations. By restricting nonessential shipping from the designated recovery area, the Federal Aviation Administration (FAA) intended to ensure the rubber recovery of spacecraft while mitigating the hazard of collision with an aircraft. At that time, most recovery operations occurred outside of U.S. territorial waters and airspace and the FAA could restrict only U.S. registered aircraft. The regulations were updated and expanded in 1984, to include launch operations from civilian spaceports and potential emergency recovery operations (aborts) in support of NASA'south Shuttle programme.

The disintegration of the Shuttle Columbia in the morn hours of February 1, 2003 was a watershed moment in the history of infinite re-entry operations and airspace traffic control, because the possibility of a Shuttle failure during state overflight at re-entry had never been considered.

The Shuttle Columbia failure began at about 70   km of altitude and led to a "progressive breakdown." Large pieces such as landing gear, turbo pumps, etc. with loftier ballistic coefficients roughshod quickly, reaching the ground within 3 to five minutes. While at that place is no protection from these fragments, they contain a very pocket-sized part of the total droppings field. Smaller fragments such every bit thermal tiles, fragments of the cargo bay doors with low ballistic coefficients, became entrained in the wind as they barbarous. Some adult a small amount of lift as they vicious, further delaying their impact with the ground, and taking up to forty   min to reach the ground. While small and low-cal, some of these pieces were large plenty to damage an aircraft. There was a substantial increase of the gamble for aviation due to Columbia'southward falling debris. Comparing with the risk criteria applied when performing rocket launches, the standard issued past the U.Due south. Range Commanders Council (RCC) requires that the probability of an aircraft existence struck by planned and unplanned inert droppings generated by infinite launches should not exceed 1 in 10 million. The Columbia blow showed that failure during re-entry could produce risks to shipping that exceed those values by several orders of magnitude.

The episode highlighted the demand to select vehicle re-entry trajectories that minimize the run a risk to basis populations and the need to accept measures to keep air traffic away from falling debris. The Columbia accident initiated a chain of events that demonstrated the need for a deliberate, integrated, arroyo to the management of air traffic and space operations.

Prior to the Columbia accident, neither FAA nor NASA took agile precautions to protect air traffic from the potential hazards of Shuttle debris falling during a re-entry accident. Thus, in the 40   min required for most Columbia debris to autumn to ground, as many as 9 instrument flying rated (IFR) ceremonious aircraft flew through the falling debris. A Continental Airline airplane flew even twice through the falling debris region. No harm was reported, only a report ended that the probability of 1 of those aircraft being struck by a piece of falling debris was equally high equally 0.1 (1 in 10) to 0.003 (3 in 1000). The assay used the all-time available models at that fourth dimension, which assumed that any touch anywhere on a commercial transport with debris of mass above 300 gr. would crusade a catastrophic blow.

Following the written report, the FAA established procedures to exist used as a real-time tool in the result of a space vehicle re-entry accident to place how to redirect aircraft around falling debris.

The tool developed for the purpose was called the Shuttle Hazard Area to Shipping Calculator (SHAAC). SHAAC used a simplified Shuttle droppings catalog to predict the size and location of the aircraft hazard area, or debris footprint, for each Shuttle state vector. Such a take chances area predicts the extent of the airspace that should contain all the falling debris potentially chancy to aircraft if the Shuttle were to pause autonomously at the time, position, and velocity associated with the input state vector.

Currently, the FAA issues Temporary Flight Restrictions (TFR) only for the airspace over the territory of the United states, including the extension out to 12 nautical miles from the coastline. Since an increasing number of commercial launches and re-entries volition occur in hereafter over U.S. territorial airspace, the FAA is in the process of updating the regulations to ensure the applicability of flying restrictions to U.S. and not-U.S. registered aircraft from entering areas designated for space operations.

Airlines

Mike Hirst , in The Air Transport Organization, 2008

6.two Setting up an airline

Setting up an airline invites some reflection on what mutual footing can be identified. First, an airline must have an owner, or owners, whose involvement volition exist largely financial. If the buying is private, long-term profitability can be expected to dominate commercial strategies, but if the airline is in public ownership information technology might take a remit to come across socioeconomic objectives and authorize for subsidies. For example, being a 'flag carrier' for a small or less than prosperous nation can exist an unprofitable business organization, merely if the reigning government believes that the losses it underwrites on the airline balance sheet are offset by positive contributions within its wider remit, which can include deterring strange airlines from diluting the national economic system past siphoning revenue into their ain economies, they will oftentimes back up such a venture.

Second, an airline must make up one's mind where it volition be based. In terms of regulatory oversight it is essential that an aircraft operator applies for a licence to operate in and around the expanse of jurisdiction of an aviation authorisation. The airline will thus accept aircraft registered in that nation or inside a nation that is recognised as offering the necessary regulatory approvals. This process cements an airline into the regulatory surround. In setting up their operation they are now obliged to keep their core functions transparent to the regulator. The initial requirements are unproblematic – declare ownership, base and mission statement. Then the regulator wants to know who volition concur key posts, and they will want declarations of flight purposes, typical destinations, aircraft types and technical documentation, such as aircraft flying manuals and individual aircraft maintenance histories and schedules. The procedure of licensing an airline takes considerable regulatory effort and is a substantial upwards-forepart cost. The aim is not to impose bureaucratic largesse, only to ensure that, from twenty-four hours one, prophylactic is given as much forethought as financial operation. In most counties a brand-new airline volition take six months or so to set up from scratch, although devolving an airline from an existing operation, either through expansion or post-merger or bankruptcy, can reduce this estimate to a few very busy weeks.

The financial and operational objectives of an airline volition ascend from noesis of issues that have been addressed under the term 'natural environment'. In that location will always exist demand for air services, wherever they are proposed, only the circumstances of each possible service have to exist understood. The proposing airline must ensure that the need is substantial plenty to justify an operation and that facilities compatible with demand are bachelor, or put in identify. In the latter area an airline begins to tread in airport and airspace issues, and while the constraints in these areas are of concern to an airline, traditionally the solutions are regarded equally beyond their business concern.

What an airline looks for in an airliner has already been debated in Chapter 5, but the route to the issues that have been discussed can expect very different when they are viewed from the airline'southward perspective. Intrinsically, airlines, from the noesis they have of the services they desire to offering, volition look for an aircraft that has the kind of functioning they desire. This means that they will associate functioning with payload and range capability, speed and thus time between origins and destinations, and seat-km operating costs. The latter is the source of most debate, in that, as has been shown, the airline tin influence the actual toll by choosing what utilisation they volition aim to achieve, how many seats they will install, what customer service features they will underwrite (which might extend to taking command of the passenger's condolement in periods prior to, and beyond, the actual time that they fly on the aircraft) and what straight costs will arise from decisions that they take. This can exist influenced past choices of salary scales, shipping lease or purchase agreements, technical and customer service subcontracting, advertising and marketing, and and then on. Airlines accept considerable freedom in these areas, and it is where the ethos that volition make them a different, or non, flying experience will reside.

It is unkind to paint a picture that presents the airlines merely equally aircraft shoppers, merely beyond influencing what is put on offer they do tend to consume 'engineering', ownership and using what they tin get to suit their own purposes. They monitor their own operation, as a service-provider, dissect the consequences of actions and initiatives – both their own and those of others – and keep an center on what technology has to offer. They will encourage their suppliers – of aircraft certainly, but all the other supporting players in their sales and service supply bondage – to match their shopping ideas with solutions that are more innovative than they were hitherto. Airlines therefore tin can stimulate the adoption of new technologies and they look engineers to sell them their ideas based on financial and service quality benefits. Airlines are not hands swayed past innovation alone. They are increasingly aware of the fact that new perspectives are necessary and they willingly embrace 'change', merely are also aware of the fear that comes from entering the unknown.

Planning is oftentimes hemmed in by constraints that ascend in 'operations', which can be the airline style of segregating limitations that are imposed past airports and airspace providers. Some airlines groan that these are sources that are external to their remits, and while they volition campaign for change they contribute nothing. More than mature managers and analysts approximate ways to react to these problems. Their attitude, typically, is contributional rather than confrontational, and it is that kind of spirit that needs to be rewarded in the fullness of time. The progress that they contribute is possible only when common indicators are identified and long-term action plans that will serve the needs of the user and not place impossible demands on the supplier have been expressed, addressed and rectified. This is an area of endeavour that requires an understanding of the processes and capabilities that affect all the contributors to the overall air transport organization.

For now, keeping within the airline domain, their service requirements have increased in complexity gradually over time. In simpler days, an airline manager was regarded as the custodian of a noble and prestigious business. An airline gear up levels of expectation for their customers that heralded adventure and had romantic inclinations, and they were high-profile businesses that demanded headlines when they set out to offer new travel experiences. Many airlines still want to promote themselves every bit inhabiting this lofty regime, but as the breadth of usage has increased the range of business strategies has opened greatly. At that place are scheduled carriers that cater for business and depression-toll need or who specialise in leisure travel, and in that location are fifty-fifty carriers that endeavour to appeal across all these categories. Nowadays airlines wing billions of passengers annually, and while they can be broadly pigeon-holed as 'flag', 'individual' or 'public, 'scheduled' or 'charter', 'low-cost', and then on, they are far from elementary businesses.

The fact that the 'model' for an airline has broadened so much, and that the change process has occurred largely on the tide of technological influences that have reformed media and public habits throughout developed and developing societies across the world, testifies to the fact that they are likewise among the virtually mod of businesses. The metamorphosis that has characterised recent decades seems sure to continue. Some cherished working practices will persist, but newer working practices will arise as fourth dimension goes by. Integrating these into a business scene that is forever more circuitous, and thus tends to be less amenable to change, is a challenge of utmost importance to the businesses involved.

Airborne Wind Free energy Systems: A review of the technologies

Antonello Cherubini , ... Marco Fontana , in Renewable and Sustainable Free energy Reviews, 2015

4.2.half-dozen Ampyx Power

The showtime visitor that developed a pumping glider generator is the Dutch Ampyx Power [51,52]. After several prototypes, they are currently developing and testing two 5.5   m 'PowerPlanes' the AP-2A1 and the AP-2A2 [53] . They are 2 officially registered shipping that are automatically controlled with state of the art avionics. They are constructed with a carbon fiber torso and a carbon courage truss which houses onboard electronics with sensors and actuators. Onboard actuators can drive a rudder, an elevator and four flaperons. One rope connects the glider to a single winch in the basis station ( Fig. iva). Ampyx Power is actually one of the few companies which has already developed an AWES [54] that is able to automatically perform the sequence of glider accept-off, pumping cycles and landing. Accept-off maneuver sees the glider lying on the ground facing the ground station at some meters of altitude. As the winch starts exerting traction force on the rope, the glider moves on the basis and, every bit soon as the lift forces exceed the weight forces, the glider takes off. They also installed a catapult for take-off and they have a propulsion system to climb up. The glider flight is fully autonomous during normal operations even though, for condom reasons, it can be occasionally controlled wirelessly from the ground thanks to a backup autopilot. The pumping cycles are similar to those of a kite. Glider landing is similar to that of an airplane and is being equipped with an arresting line so as to stop the glider in a correct position for a new take-off. During a examination campaign in November 2012, the system demonstrated an boilerplate power production of six   kW with peaks of over fifteen   kW (before tests showed tiptop in power production of 30   kW). Ampyx has started the design of its first commercial product: a 35   g wingspan AP-4 PowerPlane with a 'current of air turbine equivalent' ability of 2   MW.
