Board Equipment Of Satellite Navigation Cn-4312

CN-4312 equipment is intended for aircraft handling as a part of aircraft avionics system in all flight stages, including non precision approaches.
CN-4312 provides problem solving of navigation, plan­ning, trajectory prediction, aircraft equipment control and air navigation process control using P RNAV requirements with RNP 0.3, RNP 1, RNP 5 accuracy.
Basic modes of navigation parameter determination: SNS, SNS SBAS, SNS GBAS, IS/ADS (Inertial System/ Air Data System), DME/DME, VOR/DME.
CN-4312 provides a joint operation with user and aero­navigation by data bases, automated control of interactive systems, performing of SID/STAR/ APPROACH procedures, categories 1, APV2, APV1 landing in differential mode.
CN-4312 equipment meets the requirements of the fol­lowing documents:
