What type of airspace is NOT included in the operational limits of Group 1 UAS under VFR?

Group 1 Unmanned Aircraft Systems (UAS) are typically limited in their operations based on specific classifications of airspace established by aviation regulations. Class A airspace is designated for high-altitude operations, generally from 18,000 feet mean sea level (MSL) up to and including 60,000 feet MSL, and is specifically used for IFR (Instrument Flight Rules) operations. This class of airspace requires a higher level of certification and communication with air traffic control, making it unsuitable for the smaller, lower-flying UAS that fall under Group 1.

In contrast, Class E and Class G airspaces represent more permissive environments for UAS operations and can be utilized under Visual Flight Rules (VFR). Class E airspace allows for both VFR and IFR operations, while Class G airspace is uncontrolled airspace that permits UAS operations without requiring communication with air traffic control. Military Training Routes may also be utilized by UAS under specific conditions, but they don't fall under the same regulations as Class A airspace.

Therefore, Class A airspace is not included in the operational limits of Group 1 UAS under VFR due to the restrictions and requirements associated with operating in that airspace category.
