Regarding the small airports and heliports disappearing:
It stands to reason that any "uncontrolled" airport and helipad would disappear as warnings to Part 107 pilots. Remember, Part 107 pilots DO NOT need notify the tower of any controlled airport whose geographical center is located within 5
statute miles of your nearest sUAS flight extents.
- As a Part 101/AMA pilot, your requirement to notify airports pertains to only controlled airports (airports with a tower). A controlled airport is shown on a VFR sectional as a blue circle. Uncontrolled airports (without a tower) are shown in magenta. My guess is that your "smaller" airports that disappeared are either uncontrolled (magenta) or controlled (blue) but are outside the 5-mile radius. You can check the VFR sectionals to verify this by going HERE.
- Helipads are not typically controlled and not typically located in controlled airspace. There is one near me that is located under a Class Charlie shelf but the shelf does not start until 2,900'.
With all this being said, SAFETY is still a major consideration in sUAS operations whether flying under Part 101/AMA or Part 107. So, even if you are conducting
Part 107 sUAS operations near a
busy controlled or uncontrolled airport/heliport, it is always a good idea to either:
- Phone the controlled airport you will be flying near just as a courtesy (can't hurt our image as sUAS pilots!);
- Carry a VHF radio to monitor the CTAF(Common Traffic Advisory Frequency) and/or tower frequency as an aid to your SA (situational awareness).
Finally, I absolutely DO NOT trust helicopters to stay above the 500-ft floor...especially military helicopters; I give them a very wide berth. On a recent GA flight, I was climbing-out about a 1/2 mile from an uncontrolled airport and spotted a Blackhawk off my port side at my
same altitude. I immediately took evasive maneuvers and followed with a CTAF transmission. Silence. Then, about an hour or two later, I was flying the downwind leg of my approach pattern (~800 - 600ft) to the same airport and noticed a Blackhawk (same?) hovering at about 100-150' above the ground near the base leg of the approach. Again, CTAF transmission followed by silence. Note that I was in the traffic pattern for an uncontrolled airport NOT located in a designated MOA (Military Operations Area)!
Obviously, safety would dictate that the Blackhawk should NOT be flying in and around an uncontrolled airport's traffic pattern AND that they should have a radio tuned to the CTAF of that airport!
LESSON: Always be striving for maximum situational awareness because you
cannot depend on the other pilot(s) to adhere to the regulations.
