What class of airspace would you be operating in at the highest altitude allowed under Part 107 over the tower 4 NM NE of Pender Airport?

To determine the correct answer, it's important to understand the characteristics of the different classes of airspace and how they relate to operations under Part 107, which governs the use of small unmanned aircraft systems (sUAS).

At the highest altitude allowed under Part 107 regulations, which is 400 feet AGL (Above Ground Level), when operating within 4 nautical miles northeast of Pender Airport, the airspace classification would typically be Class E.

Class E airspace is generally used to transition to and from more controlled areas and extends from a designated altitude (usually 1,200 feet AGL and above) down to the surface in certain areas, which could include transitional or airspace needed for certain airports. In many cases, Class E airspace extends up to the lower limits of the associated controlled airspace requirements.

While it's possible that part of the airspace might also intersect with Class G or D airspace, depending on the proximity and altitude of the airport operations, if you are at the maximum altitude allowed under Part 107, you would likely be operating within Class E, as it provides the necessary regulations for staying clear of controlled operations while still handling unmanned operations effectively.

In contrast, Class G airspace is uncontrolled
