subsonic jet

As a result Concorde pilots must use their brains to operate controls that on newer subsonic jets are run by computer.

The drone of a subsonic jet approaching from the south brought Bolan back to full alert.

Subsonic jet engines employ relatively low, subsonic, exhaust velocities.

First generation subsonic jet fighters (mid-1940s to mid-1950s)

Though maintenance costs for the jets are four times as high as those for a subsonic jet, the airlines still make a profit on the Concorde.

The subsonic jets of the 1980's, packed with hundreds of passengers seated ten abreast, could not even begin to match such comfort and spaciousness.

In 1981, the unit converted to the A-7D Corsair II, a subsonic jet designed for close-air support.

Modern subsonic jet aircraft usually use high-bypass turbofan engines which offer high speed with fuel efficiency comparable (over long distances) to piston and propeller aeroengines.

The first generation of jet fighters comprised the initial, subsonic jet fighter designs introduced late in World War II and in the early post-war period.

Passengers will have the option in Ecuador of taking a trip to the Galapagos Islands and returning to New York in first class on a subsonic jet.

The aim of this regulation is to prevent a further increase in noise pollution in the Community due to recertificated subsonic jet aeroplanes, as I have just mentioned.

MiG-17F/F-5: The MiG-17, and Shenyang F-5 are subsonic jet fighters.

As the most advanced supersonic transports became some of the oldest airframes in the fleet, they also fell to the economics of new efficient subsonic jets and upgrade costs.

Meanwhile, 8 of the 60 British Airways flight crew members (captains, co-captains and flight engineers) have retired, and about 20 have shifted to subsonic jets, mostly 747's.

The order for the subsonic jets, which were developed in a venture between Embraer and Italian partners, is the Brazilian company's first significant military contract in Latin America.

The product line was broad and came to include ammunition, grenades, mines, armored personnel vehicles, patrol boats, navy patrol planes, turboprop trainers, tanks, and subsonic jet fighters.

Lockheed sought an airplane with cruise speeds of around 2,000 mph (3,219 km/h) with takeoff and landing speeds that compared to large subsonic jets of the same era.

Mr. Bush did well, Mr. Dotti said - "I'd fly with him again" - and moved on to subsonic jet trainers in February, then to supersonic jets.

When these high bypass jet engines reached commercial service in the 1960s, subsonic jet engines immediately became much more efficient, closer to the efficiency of turbojets at supersonic speeds.

"Personally," Mr. Hefner said, "I think you and I will be able to ride supersonically in the year 2000, as cheaply as we could in an old fashioned subsonic jet."

In 1945, during the final phase of the war, newly developed subsonic jet planes like the first jet-powered bomber Arado 234 were stationed at the airfield and the runway was extended by several hundred metres.

It would take 100 hours on the Concorde or 200 hours on subsonic jets a year to reach the exposure limit set by international authorities for members of the public, Dr. Bagshaw said in an interview.

Indeed it has been found - since testing was first begun with Air France in 1963 - that radiation exposure on Concorde is no greater than that of the subsonic jet despite the difference in flying height.

Wiggs decided to collate and publish the scientific information available about the sonic boom, airport noise, and astronomical fuel use (Concorde used 2.5 x times the amount of fuel per passenger mile as subsonic jets).

Everyone in Howard Beach knows that airplane noise is louder on takeoff than landing, louder in summer than winter (dense, humid air means planes need more lift) and louder with the Concorde than a subsonic jet.
