FlightRadar anomaly finder to find juicy flights >:) -- Tom Van de Wiele

Checks every 15 seconds:

1. Is a flight in the air that we can detect locally with dump1090-fa, but is NOT on Flightradar24 or FlightAware (administratively "hidden" flights)
2. Do we see fast acceleration or acceleration beyond the capabilities of a commercial airliner or light aircraft
3. Do we see fast climbing/descending beyond the capabilities of a commercial airliner or light aircraft

If we get a change of 50 knots or 1000 feet difference within 30 seconds we run the ./alert command. Replace with your IRC/other bots

If you do not want to use the paying FlightRadar24 API, comment out 4 lines at line 107

Note: If you are receiving ADSB at an airport you will have to add error checking to not get alerted when planes take off/land

Flight Characteristics Background (MIGHT NEED TWEAKING)

1. Commercial Jet Airliners

• Acceleration/Deceleration: At a typical rate of 1 to 3 knots per second in 15 seconds slow down by approximately 15 to 45 knots
• Climb Rate: The average initial climb rate for a commercial jet is between 2,000 to 3,000 feet per minute (varies depending on the aircraft load and weather conditions)
• Descent Rate: Normal descent rates are around 1,500 to 2,000 feet per minute, can be faster if needed for e.g. CDA (Continuous Descent Approaches)

2. Light Aircraft (e.g. Piper, Cessna)

• Acceleration/Deceleration: Takeoff speeds are around 100-160 kph (60-100 mph) and can stop within shorter distances often less than 800 feet
• Climb Rate: Climb rates ranging from 500 to 1,200 feet per minute. High-performance models e.g. Cessna 182 can climb a bit faster
• Descent Rate: Typically at 500 to 1,000 feet per minute

3. Combat Planes

• Acceleration/Deceleration: e.g F-16 can reach speeds over Mach 2 and rapid deceleration is possible
• Climb Rate: e.g. F-15 Eagle can climb at over 50,000 feet per minute in a zoom climb
• Descent Rate: Can descend very quickly, exceeding those of commercial and light aircraft
