At least once a week somebody sends me an email about an ADS-B traffic target that suddenly appeared on their EFB app, often just a hundred feet above or below, and less than half a mile behind. The reporter is never able to spot the target, which appears to doggedly follow them for a few minutes before disappearing. No, this is not a UFO or a new stealth drone. It’s just an annoying (and occasionally panic-inducing) artifact of the way ADS-B works.

No, you are not being followed by one of these.

If you’re being chased by ghosts, don’t worry – you’re not alone. It’s not an issue that’s specific to FlightBox or to whatever EFB app you’re using. Every ADS-B In system occasionally displays a ghost, even for those of us […]

Just a quick “thank you” to everyone who has waited patiently for the past two weeks. The vacation in France was amazing and an excellent opportunity to recharge the batteries. I’ve already begun digging out and will be shipping all of the backorders on Monday. I’ll also be going through nearly 500 email messages. It may take a day or so, but I will respond to all of them.

One other item of business: I’m extending the deadline for the AHRS Challenge. If you’re interested, you now have until July 15. Please keep in mind that the entries will be tested in the order they were received. The first entry to meet the qualifications will receive the bounty, so get your entry in as soon as you have it tested and feel confident that it will work.
