last thread some anon posted this:

"Ninety-nine percent of the “emergencies” observed on websites like FlightRadar24 are very benign events. Unfortunately, Twitter seems to go nuts when an aircraft squawks 7700. “Emergency” doesn’t necessarily mean passengers and crew are in a life and death struggle worthy of the evening news. Most of the time, the crew is using an abundance of caution and letting ATC know that they are working with an abnormal situation."

so there you have it from your own source. if its not a real emergency, then: "Most of the time, the crew is using an abundance of caution and letting ATC know that they are working with an abnormal situation."

so it is either a real emergency or an abnormal situation. = not ever normal
