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].
These delayed signals cause measurement errors that are different for each type of GPS signal due to its dependency on the wavelength. [4] A variety of techniques, most notably narrow correlator spacing, have been developed to mitigate multipath errors. For long delay multipath, the receiver itself can recognize the wayward signal and discard it.
The transponder gets its altitude information from an encoding altimeter mounted behind the instrument panel that communicates via the Gillham code. Gillham code is a zero-padded 12-bit binary code using a parallel nine- [ 1 ] to eleven-wire interface , [ 2 ] the Gillham interface , that is used to transmit uncorrected barometric altitude ...
An Air Data Inertial Reference Unit (ADIRU) is a key component of the integrated Air Data Inertial Reference System (ADIRS), which supplies air data (airspeed, angle of attack and altitude) and inertial reference (position and altitude) information to the pilots' electronic flight instrument system displays as well as other systems on the aircraft such as the engines, autopilot, aircraft ...

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.
In ISA temperature conditions the altimeter will read the height above the airfield/runway in the vicinity of the airfield. SPS/STD - 'Standard Pressure Setting' or just 'Standard' refers to the altimeter being set to the standard pressure of 1013.25 hPa. It is the setting that causes an altimeter to read the aircraft's flight level (FL).
The instrument may develop small errors, in pitch or bank during extended periods of acceleration, deceleration, turns, or due to the earth curving underneath the plane on long trips. To start with, they often have slightly more weight in the bottom, so that when the aircraft is resting on the ground they will hang level and therefore they will ...
