Methods of flight parameters indications matching in helmet-mounted display systems

The article presents selected results of the analytical work carried out in the Air Force Institute of Technology regarding the possibility of computer matching systems, digital display and analogue devices, both in the static states and in dynamic states while manoeuvring the aircraft. On the example of parameter of vertical speeds provided a method of matching the indications for the helicopter Mi-17-1V with built helmet-mounted display system of flight data SWPL-1 Cyclops (developed by the Air Force Institute of Technology and cooperating with analogue avionics). Adjusting the display of vertical speed achieved by an inertial element of first row, implemented programmatically in the computer graphics KG-1. On the other hand, method of adjusting of indications on the information presented in the helmet-mounted cueing system NSC-1 Orion (built in the Air Force Institute of Technology for helicopter W-3PL Capercaillie) and obtained from the integrated avionics system (with digital avionics), exemplified by magnetic heading (obtained from heading layout KCS-305) and geographic heading (obtained from inertial navigation system EGI-3000). Adjusting of indications realized by introducing amendments to the indications of the multifunctional monitor MW-1, translucent display HUD and helmet-mounted display WDN-1 (in the form of elected declination, implemented programmatically on the computer mission KM-1) and the amendments to the magnetic deviation (introduced periodically to heading compensator layout KCS-305).
