The main drawback was that the high drag of a pusher type's tail structure made it slower than a similar " tractor " aircraft.

Following the first three fatal Australian D. H. 86 accidents and a forced landing to VH-USW Lepena on 13 December 1935 ( a Friday ) when the pilot believed his aircraft was about to break up in mid-air, the Australian Government temporarily suspended the type's Certificate of Airworthiness.

ATL could not match the scale of its competitors ' investments, both in the design and development of the aircraft itself as well as in marketing the aircraft to potential customers.

This can cause downbursts, a potential hazardous condition for aircraft that fly through it, as a substantial change in wind speed and direction occurs, resulting in decrease of lift of the aircraft.

These videos detail the Active Aeroelastic Wing two-phase NASA-Air Force flight research program to investigate the potential of aerodynamically twisting flexible wings to improve maneuverability of high-performance aircraft at transonic and supersonic speeds, with traditional control surfaces such as ailerons and leading-edge flaps used to induce the twist.

By 1918, the potential advantages of air-cooled radials over the water-cooled inline engine and air-cooled rotary engine that had powered World War I aircraft were appreciated but remained unrealized.

The oil crisis of the 1970s was a serious shock to the commercial aviation industry, as a major manufacturer of commercial aircraft at the time, McDonnell Douglas was hit by the economic shift and forced to contract heavily while diversifying into new areas to reduce the impact of potential future downturns.

Attack aircraft are best suited for use on tactical level rather than operational or strategic, which means destroying targets of immediate military value, not the targets that could affect future military potential.

In an aircraft installation with a floating battery electrical system the regulator voltage is set to charge the battery at constant potential charge ( typically 14 or 28 V ).

The United States Department of Transportation ( DOT ) Federal Aviation Administration ( FAA ) conducted testing and released a report which in summary states "... the release of hydrogen gas from these flameless ration heaters is of a sufficient quantity to pose a potential hazard on board a passenger aircraft.

Using a variety of additional aerodynamic surfaces — known as high-lift devices — like leading edge extensions ( leading edge wing root extensions ), fighter aircraft have increased the potential flyable alpha from about 20 ° to over 45 °.

Following the J 1, a series of " J-designated " aircraft followed, each advancing the state of the art in terms of strength and weight, but no single design progressed much beyond the prototype stage in terms of production potential.

* Raytheon's Universal Control System ( UCS ) is an unmanned aerial system ( UAS ) " cockpit " that improves operator awareness and efficiency, while providing the ability to control multiple unmanned aircraft, and reduce potential accidents.

Galland became an enthusiastic supporter of the aircraft, realising its potential as a fighter rather than a " Blitzbomber ".

After the surrender of the Argentine ground forces on the islands, the British still faced the problem of potential Argentine air attacks from Argentina, so an aircraft carrier had to remain on station to guard the islands with its squadron of Sea Harriers until the local airfield was prepared for jet aircraft.

Meanwhile, flying prototypes of aircraft powered by alternative fuels, such as ethanol, electricity, and even solar energy, are becoming more common and may soon enter the mainstream, at least for light aircraft.

The first jet aircraft to enter service in October 1980 were six Alpha Jet CI light attack and advanced training aircraft ; six more were ordered, but were subsequently cancelled.

The first aircraft carrier due for decommissioning that would enter the SRP is planned to be Enterprise, intended for withdrawal in 2013.

Two new Queen Elizabeth class carriers able to operate the F-35B short take-off and landing variant of the US Lockheed Martin Lightning II aircraft are under construction ; it is not certain if both carriers will enter service or the number of aircraft that will be purchased.

* The 2037 Bomber, an optionally manned, stealthy, hypersonic, heavy-bomber is scheduled to enter service this year, as the USAF calculates that attrition will have reduced their existing strategic bomber fleet below the minimum 170 aircraft.

This increases the lift from the advancing wing and accentuates the probability of the aircraft to enter into a spin.

* Rolls-Royce Conway, the first turbofan aircraft engine to enter service

B-2 bombers were the first U. S. aircraft to enter Afghanistan airspace in October 2001, paving the way for other coalition aircraft to engage Taliban and Al Queda forces.

The airport's three runways provide a platform for future growth while the airport can accommodate extra-wide aircraft such as the Airbus A340 and Airbus A350, the former already in service and the latter being scheduled to enter service at Helsinki Airport with Finnair in the coming decade.

On 22 April 1970, BOAC received its first 747, but the aircraft did not enter commercial service for almost a year, on 14 April 1971, due to BOAC's inability to settle crewing and pay rates for the 747 with the British Air Line Pilots ' Association.

* HMS Prince of Wales ( R09 ) will be the second of two Queen Elizabeth class aircraft carriers and is scheduled to enter service in 2018.

The policy was so strict that even newly purchased identical aircraft ( one from each airline ) were required on their delivery flights to enter Australian airspace at exactly the same time.

It also decided to sell all the Douglas DC-3 and Auster aircraft in September 1957 and enter into a five-year agreement with BEA for the latter to operate services on behalf of Cyprus Airways.

Of the 16 aircraft, two did not enter commercial service and 8 were in service as of April 2003.

The first YP-84A Thunderjet flew on February 28, 1946, but the aircraft was plagued with so many developmental problems that the first F-84B didn't enter Air Force service until 1949.

Cochran was also the first woman to land and take off from an aircraft carrier, the first woman to reach Mach 2, the first woman to pilot a bomber across the North Atlantic ( in 1941 ), the first pilot to make a blind ( instrument ) landing, the only woman ever to be President of the Federation Aeronautique International ( 1958 – 1961 ), the first woman to fly a fixed-wing, jet aircraft across the Atlantic, the first pilot to fly above 20, 000 ft with an oxygen mask, and the first woman to enter the Bendix Transcontinental Race.

This problem was solved by having the launch aircraft slow down and enter a climb to avoid overtaking the bomb as it fell.

The U. S. Navy then ordered production of the TBM-3W, the first production AEW aircraft to enter service.

In many cases with the U. S. the first word of the name has to do with the intent of the program, programs with HAVE as the first word, such as HAVE BLUE for the stealth fighter development, are developmental programs, not meant to produce a production aircraft, while programs that start with Senior, such as Senior Trend for the F-117, are for aircraft in testing meant to enter production.
