* Aircraft Classification Number, ICAO standard number indicating the pavement load imposed by an aircraft

It is defined as the range of speeds between the critical Mach number, when some parts of the airflow over an aircraft become supersonic, and a higher speed, typically near Mach 1. 2, when all of the airflow is supersonic.

They will assess the size of the aircraft and the number, type and position of its engines.

Some smaller designs have been used as the basis for specialist fighters, such as night fighters, and a number of fighters, such as the Hawker Hurricane were used as ground attack aircraft bombers, replacing earlier conventional light bombers that proved unable to defend themselves and carry a reasonable bombload.

The Warriors were not only used for pilot training, but also as light strike aircraft, and a number of them were employed by the FABF's Escadrille de Chasse ( EdC ).

Like von Seeckt, he concluded that France could no longer maintain the huge armies of conscripts and reservists with which World War I had been fought, and sought to use tanks, mechanised forces and aircraft to allow a smaller number of highly trained soldiers to have greater impact in battle.

The Bermuda Triangle, also known as the Devil's Triangle, is a region in the western part of the North Atlantic Ocean where a number of aircraft and surface vessels are said to have disappeared under mysterious circumstances.

* The number of ships and aircraft reported missing in the area was not significantly greater, proportionally speaking, than in any other part of the ocean.

In fact, the number of supposed disappearances is relatively insignificant considering the number of ships and aircraft that pass through on a regular basis.

On December 28, 1948, a Douglas DC-3 aircraft, number NC16002, disappeared while on a flight from San Juan, Puerto Rico, to Miami.

The UN operates a large fleet of aircraft and helicopters, and compared to other African countries the DRC has a large number of small domestic airlines and air charter companies.

A number of accidents have occurred where outward-opening aircraft doors were opened in flight, often accidentally:

As a part of military nomenclature, a letter is often assigned to various types of aircraft to indicate their use, along with a number to indicate the specific aircraft.

The actual aircraft used by Wintgens in his pioneering aerial engagement, his Fokker M. 5K / MG with IdFlieg military serial number " E. 5 / 15 ", as it appeared at the time of the engagement.

In the 1980s Guyana Airways Corporation's domestic operations started to deteriorate for a number of reasons, not least among them the unrealistically low fares it was required to charge and the lack of access to foreign exchange for imported aircraft parts and other requirements.

In the post-war period the R4M served as the pattern for a number of similar systems, used by almost all interceptor aircraft during the 1940s and ' 50s.

The AAF was very significant before and during the 1980s but by the time of the U. S. invasion of Afghanistan in 2001, the number of aircraft available was minimal.

As of 2012, the AAF has over 100 refurbished aircraft, which includes a number of C-27A Spartan and Antonov AN-32 military transport aircraft as well as Mi-17 and Mi-24 helicopters.

As the number of the Afghan armed forces is growing rapidly so is the need for more aircraft and vehicles.

* 1992 – USAir Flight 405 crashes shortly after liftoff from New York City's LaGuardia Airport, leading to a number of studies into the effect that ice has on aircraft.

The air force did not get a combat capability until a number of MiG-17 aircraft were presented by the Soviet Union in 1966.

Though Catherine was vexed at the number of French officers streaming to the Turkish standard, there were several under her own, such as the Prince De Nassau ; ;

In the eighteenth century there emerges for the first time the notion of a private tragedy ( or nearly for the first time, there having been a small number of Elizabethan domestic tragedies such as the famous Arden Of Feversham ).

In addition, the SBA uses such criteria as number of employees and dollar volume of the business.

Rather, such assignments are made, as they must be, on the basis of certain overall rules and standards, representing to some extent a statistical approach to the problem, taking into account for each situation some of the variables ( e.g., power and station separations ) and averaging out others in order to achieve the balance which must be struck between protection against destructive interference and the assignment of a number of stations large enough to afford optimum radio service to the Nation.

The final choice of material depends upon such factors as costs, method of fabrication, degree of complexity, number of units required, time available for tooling, and projected life expectancy of the unit.

In addition, many of the hard-surface cleaners used for walls and woodwork had their genesis in trisodium orthophosphate, which is still the major ingredient of a number of such products.

There may be a number of secondary effects resulting from diffusion through buildings such as widespread contamination of kitchens, restaurants, food stores, hospitals, etc..

The number of successes on each shot is a value of a random variable that has values 0 or 1, and there are 5 such random variables here.

In the following paper it is shown that in a certain definite sense, exactly an odd number of squares can be inscribed in every such curve which does not contain an infinite number of inscribed squares.

We note that two such curves C and Af, cannot coincide at more than a finite number of points ; ;

There must be an odd number of such components, which will be called complete components.

Moreover, whereas in Interstate Commerce Commission parlance `` variable cost '' means a cost deemed to vary in direct proportion to changes in rate of output, in the type of analysis now under review `` variable cost '' has been used more broadly, so as to cover costs which, while a function of some one variable ( such as output of energy, or number of customers ), are not necessarily a linear function.

As already noted in an earlier paragraph, the more familiar cost analyses of utility enterprises or utility systems divide the total costs among a number of major classes of service, such as residential, commercial, industrial power, street lighting, etc..

Because individual classes of foods differ in their requirements for preservation, a number of methods have been developed over the years involving one or a combination of procedures such as dehydration, fermentation, salting, chemical treatment, canning, refrigeration, and freezing.

A number of adjustment features are included in the Hesiometer to facilitate measurement and permit ready removal of coatings deposited on such substrates as iron and other metals, glass, wood, and plastic surfaces.

Three seconds flat is the usual time, and the space is crossed by moderate mileage, while the overwhelming immensity of such journeys must be conceived as a static pulsation through an enormous number of coexistent frequencies which perpetuate all events.

This means that such factors as the health of the parents, particularly the mother, their ability to provide their children with the necessities of life, the degree of population density of a country and the shortage of housing facilities may legitimately be taken into consideration in determining the number of offspring.

`` Only a relative handful of such reports was received '', the jury said, `` considering the widespread interest in the election, the number of voters and the size of this city ''.

Lower costs and a larger number of stations are the key factors making such specialization possible.

Synthesis of new elements is accomplished by bombarding target atoms of heavy elements with ions, such that the sum of the atomic numbers of the target and ion elements equals the atomic number of the element being created.

The order is a cosmopolite ( plants found throughout most of the world including desert and frigid zones ), and includes mostly herbaceous species, although a small number of trees ( such as the giant Lobelia and the giant Senecio ) and shrubs are also present.

In many cases such a selection can be made without invoking the axiom of choice ; this is in particular the case if the number of bins is finite, or if a selection rule is available: a distinguishing property that happens to hold for exactly one object in each bin.

One motivation for this use is that a number of generally accepted mathematical results, such as Tychonoff's theorem, require the axiom of choice for their proofs.

A number of ancient cities were located here, such as Troy, Assos, Pergamon ( Bergama ), Sardis, Ephesus, Miletus, Halicarnassus ( Bodrum ), Smyrna ( İzmir ), Hierapolis ( Pamukkale ), Magnesia ( Manisa ), Philadelphia ( Alaşehir ), Didyma ( Didim ), Aphrodisias, Kaunos, Knidos, among others.
