Airspeed And Ground Reference Maneuvers

The idea is to adjust your bank angle to compensate for changing groundspeeds, which depend on your airspeed.  

This file contains chapter 4, 5, and 6 of the handbook.

Key Takeaways:

  • The article clarifies the often-confusing interplay of different airspeed types—Indicated (IAS), Calibrated (CAS), True (TAS), and Groundspeed (GS)—highlighting their individual roles in flight performance, lift generation, and navigation.
  • Ground reference maneuvers, such as "Turns Around A Point," demonstrate the practical application of groundspeed management by requiring pilots to adjust bank angle to maintain a constant radius around a ground reference despite varying wind conditions.
  • More complex maneuvers like "On-Pylon 8s" further illustrate groundspeed's impact, demanding continuous adjustments to altitude (pivotal altitude) to maintain a visual pivot point with ground references.
  • Mastering these maneuvers is crucial for developing essential pilot skills in aircraft control, attention division, and effectively managing the dynamic relationship between airspeed, groundspeed, and wind compensation.

Many flight instructors dread airspeed. Don’t get me wrong; We like having the right airspeed on approach, but airspeed is a hard concept to teach. It’s hard to teach because it’s actually a handful of concepts. Even experienced pilots get confused about airspeed and the different types. Knowing which airspeed concept to apply and when can simplify a lot of the mysteries of flying. And for some operations, we adjust airspeed to obtain the desired groundspeed. Confused yet?

Students working toward a private pilot certificate do turns around a point; those working on a commercial certificate do on-pylon 8s. These maneuvers sharpen stick-and-rudder skills, and they illustrate the different concepts of airspeed in ways that you can see in action. Let’s review.
