Aircraft Autonomous Integrity Monitoring (AAIM)
AAIM is a method of monitoring the integrity of the GNSS position data, using information from on board sensors such as barometric altitude data, IRS position data and conventional nav-aid autotuning (VOR, DME position data). This can allow our aircraft to notice any suspicious GNSS position data and notify the pilots that it may not be correct. It is a type of ABAS (Aircraft-Based Augmentation System).
