Ground-truthing and field checks were made by resurveying selected villages using a light aircraft and a jeep.
Previous field studies have indicated that children's cognitive performance is impaired by chronic aircraft noise exposure.
Aircraft may be unable to land or take-off for several days or occasionally weeks.
The framework consists of the knowledge-based system, integrated with numerical analysis tools including an aircraft performance0sizing code and a life-cycle cost analysis code.
For example, when performing airfoil or aircraft calculations, the functionals of interest are almost always surface integrals.
These trials led to the domes' ultimate tests, in the role of portable aircraft hangars.
In turn, the airlines would not purchase the aircraft unless they too are assured of making a profit by operating the aircraft.
The value of aircraft exports rose from £26 million in 1948 to £64 million in 1955.
