We love moving maps, be they in the panel or on the portable. Just remember that they don’t always show all the airspace, or even show it in the same way.
Varied TRSA Depictions
In-betweens are always tough, and have the potential for trouble. Flying some IFR practice in VFR conditions is a perfect example. Youre emulating one set of rules (IFR) but youre actually bound by another set (VFR). There are all sorts of potential traps here: maintaining cloud clearances, conflicting with traffic youd normally be separated from, and blundering into airspace without the required communication or permission.
Key Takeaways:
- Terminal Radar Service Areas (TRSAs) are unique airspace where participation is voluntary; however, once a pilot accepts services, they are bound by ATC instructions.
- TRSA depiction is inconsistent across paper charts (e.g., absent on IFR en route charts) and varies significantly on digital navigation and moving map systems, posing a challenge for pilot awareness.
- Pilots are generally encouraged to participate in TRSA services for benefits like traffic advisories and ATC practice, but must be vigilant about how these areas are displayed on their specific navigation tools.
