#VFR VISIBILITY REQUIREMENTS CODE#

Autopilots may or may not be installed with an associated Flight Director System (FD). These systems typically have a control panel for mode selection, and system for indication of mode status. Attitude retention may be a SAS function, or may be the basic “hands off” autopilot function.Īutopilot Systems (APs), which provide for “hands off” flight along specified lateral and vertical paths, including heading, altitude, vertical speed, navigation tracking, and approach. Changes in desired attitude can be accomplished usually through a four-way “beep” switch, or by actuating a “force trim” switch on the cyclic, setting the attitude manually, and releasing. Like trim systems, SAS supports “hands on” flying.Īttitude Retention Systems (ATTs), which return the helicopter to a selected attitude after a disturbance. Stability Augmentation Systems (SASs), which provide short-term rate damping control inputs to increase helicopter stability. This is a system that supports “hands on” flying of the helicopter by the pilot. These systems typically involve a magnetic brake/spring device, and may also be controlled by a four-way switch on the cyclic. Trim systems, which provide a cyclic centering effect. Typically, these systems fall into the following categories:Īerodynamic surfaces, which impart some stability or control capability not found in the basic VFR configuration. To meet these requirements, helicopter manufacturers usually utilize a set of stabilization and/or Automatic Flight Control Systems (AFCSs). The certification requirements for helicopters to operate under Instrument Flight Rules (IFR) are contained in 14 CFR Part 27, Airworthiness Standards: Normal Category Rotorcraft, and 14 CFR Part 29, Airworthiness Standards: Transport Category Rotorcraft.
