Flight Inspection Systems
Flight Inspection Systems are installed in aircraft, and they have dedicated antennas, receivers/transceivers and sensors to collect (usually real-time acquisition) data from navigation aids under inspection. The data received by this equipment are decoded by flight inspection computers and compared with the real aircraft position, which accuracy is essential. This position can be calculated by several devices and techniques (GPS, inertial systems, barometric systems, landmark systems...) or sent to the flight inspection aircraft by external (usually optical) devices. This process results are displayed on operator/inspector workstations, also installed in the aircraft.

Famous quotes containing the words flight, inspection and/or systems:
“AIDS was ... an illness in stages, a very long flight of steps that led assuredly to death, but whose every step represented a unique apprenticeship. It was a disease that gave death time to live and its victims time to die, time to discover time, and in the end to discover life.”
—Hervé Guibert (1955–1991)
“Thus the orb he roamed
With narrow search, and with inspection deep
Considered every creature, which of all
Most opportune might serve his wiles, and found
The serpent subtlest beast of all the field.”
—John Milton (1608–1674)
“No civilization ... would ever have been possible without a framework of stability, to provide the wherein for the flux of change. Foremost among the stabilizing factors, more enduring than customs, manners and traditions, are the legal systems that regulate our life in the world and our daily affairs with each other.”
—Hannah Arendt (1906–1975)
