Feeling a little rough on your IFR skills? Log a few hours on the NEW Hub City Aviation Instrument Simulator. Hub City Aviation’s new Redbird FMX AATD simulator is one of the best around! This simulator has been approved by the Federal Aviation Administration (FAA) for students to log instrument approaches for training and currency requirements. The simulator can even be used to complete an instrument proficiency check (IPC) except for a circle approach/maneuver which must be accomplished in a real aircraft.
