Helicopter with hidden identity using PIA headed to LA, FFL764, hex A03D74. Might be one of Bezo's since its coming from West Texas, but unsure. Would love a spot.

I analyzed the impact of the FAA's ban on simultaneous parallel approaches at SFO, which went into effect on March 31, 2026. The number of TCAS Resolution Advisories (RAs) fell by about 90%. (cc/ @thisisaaronland.bsky.social)
A two-panel chart titled "KSFO: the end of simultaneous parallel approaches and the collapse in TCAS RAs," plotting data from roughly mid-December 2025 to mid-June 2026. A vertical dashed line intersects both charts, labeled "FAA ban Mar 31 2026."
Top Chart: Titled "Simultaneous parallel approaches per day at KSFO." It displays a blue line representing the 7-day average of approaches. Before the ban, the daily approaches fluctuated heavily with a "before-ban avg 45/day." Immediately following the March 31 ban, the line flatlines to an "after-ban avg 0.0/day."
Bottom Chart: Titled "TCAS Resolution Advisories (RAs) per day at KSFO (approach corridor + field)." It displays a red line representing the 7-day average of RAs. Before the ban, RAs occurred frequently with a "before-ban avg 2.6/day." After the ban, the line drops significantly to an "after-ban avg 0.3/day."
The bottom left corner cites the source as "airplanes.live ADS-B data."

Some really exciting work I’ve been doing to identify and link FAA Privacy ICAO Addresses to real aircraft. For historical PIA hexes and future hexes.

We already know N7628 and N8728 are the new SpaceX/Elon aircraft. But the tail numbers N9728, N3628, and N1628 are also reserved using the same Gulfstream lawyers as the 7628 and 8628.

Jeff Bezos just flew his Gulfstream G700 N11AF from Titusville, Florida after a visit to Blue Origin down to Miami. From there, he transferred to his helicopter and flew from the airport to his home on Indian Creek. The helicopter, N2AF, is operating under a privacy ICAO address to mask its identity

“Most business jet operators don’t use the busiest commercial airports,” says NBAA. That ignores the fact they still fly in the same airspace and talk to the same ARTCC controllers as the airlines once airborne. Many business airports sit right next to major hubs still adding to traffic.

The new restrictions come less than a week after the FAA ordered commercial airlines to cut flights due to air traffic controller staffing shortfalls.

NK1300 and AF1 had a bit of an "encounter" today-- ATC was reportedly yelling at NK1300 to get their attention to get them to alter course. Not sure it was a "close call" at all, but since AF1 involved.. I tend to believe the yelling part. Thanks to @petchmo.bsky.social for his help in..
