Navigation Systems - Task A
Knowledge
Ground-based navigation (orientation, course determination, equipment, tests, and regulations), including procedures for intercepting and tracking courses and arcs.
Satellite-based navigation (orientation, course determination, equipment, tests, regulations, interference, appropriate use of databases, Receiver Autonomous Integrity Monitoring (RAIM), and Wide Area Augmentation System (WAAS)), including procedures for intercepting and tracking courses and arcs.
Risk Management
Management of automated navigation and autoflight systems.
Distractions, task prioritization, loss of situational awareness, or disorientation.
Limitations of the navigation system in use.
Skill
Tune and identify the navigation facility/program the navigation system and verify system accuracy as appropriate for the equipment installed in the aircraft.
Determine aircraft position relative to the navigational facility or waypoint.
Set and orient to the course to be intercepted.
Intercept the specified course at appropriate angle, inbound to or outbound from a navigational facility or waypoint.
Maintain airspeed ±10 knots, altitude ±100 feet, and selected headings ±5°.
Apply proper correction to maintain a course, allowing no more than ¾-scale deflection of the course deviation indicator (CDI). If a distance measuring equipment (DME) arc is selected, maintain that arc ±1 nautical mile.
Recognize navigational system or facility failure, and when required, report the failure to air traffic control (ATC).
Use a multi-function display (MFD) and other graphical navigation displays, if installed, to monitor position, track wind drift, and to maintain situational awareness.
At the discretion of the evaluator, use the autopilot to make appropriate course intercepts, if installed.
Use single-pilot resource management (SRM) or crew resource management (CRM), as appropriate. 13
