What type of heading is displayed in the HUD when CAS/TAS is selected?

• A. True heading
• B. Magnetic heading
• C. Track heading
• D. Ground track heading

Answer: (B)

When Calibrated Airspeed (CAS) or True Airspeed (TAS) is selected in a Heads-Up Display (HUD), the type of heading shown is the magnetic heading. This is significant because magnetic heading refers to the direction the aircraft is pointing relative to the Earth's magnetic field. Pilots often utilize magnetic heading as it provides a consistent reference for navigation and is critical for aligning with navigation aids and air traffic control instructions. In the context of aviation, using magnetic heading is essential for accurate navigation, especially when flying in areas where magnetic variation (the difference between true north and magnetic north) is a concern. This is the reason why pilots must be well-versed in understanding magnetic heading, as it is a crucial factor in flight planning and in-flight navigation. Choosing magnetic heading over other types like true heading, track heading, or ground track heading ensures that the pilot is aligning their navigation with actual compass readings and instrumentation, making it the appropriate selection when CAS/TAS is used. The other headings might refer to different navigational concepts but do not align specifically with the data presented when selecting airspeed types in a HUD.
