The system error, including position error, ..., may not exceed three percent of the calibrated airspeed or 5 knots (9.3 km/h), whichever is greater, throughout the [operating speed range for the aircraft].
The attitude indicator (AI), also known as the gyro horizon or artificial horizon, is a flight instrument that informs the pilot of the aircraft orientation relative to Earth's horizon, and gives an immediate indication of the smallest orientation change.
In aviation, a flight level (FL) is an aircraft's altitude as determined by a pressure altimeter using the International Standard Atmosphere. It is expressed in hundreds of feet or metres. The altimeter setting used is the ISA sea level pressure of 1013 hPa or 29.92 inHg. The actual surface pressure will vary from this at different locations ...
12 November 1996, an Il-76 collided in mid air with a Saudi B747 near New Delhi India, following a level bust by the Il-76.; 12 November 1996, a B737 descended below its assigned holding level in the LHR stack, in IMC, to within 100 feet vertically and between 680 and 820 metres horizontally of an MD-81 at its correct level.
The cockpit of a Slingsby T-67 Firefly two-seat light airplane.The flight instruments are visible on the left of the instrument panel. Flight instruments are the instruments in the cockpit of an aircraft that provide the pilot with data about the flight situation of that aircraft, such as altitude, airspeed, vertical speed, heading and much more other crucial information in flight.
At least one satellite, in addition to those required for navigation, must be in view for the receiver to perform the RAIM function; thus, RAIM needs a minimum of five satellites in view or four satellites and a barometric altimeter (baro-aiding, a method of augmenting the GPS integrity solution by using a non-satellite input source) to detect ...
It uses a contour map of the terrain that is compared with measurements made during flight by an on-board radar altimeter. A TERCOM system considerably increases the accuracy of a missile compared with inertial navigation systems (INS). The increased accuracy allows a TERCOM-equipped missile to fly closer to obstacles and at generally lower ...
QFF is the location value plotted on surface synoptic chart and is closer to reality than QNH, though it is only indirectly used in aviation. [ citation needed ] Another method [ which?
