Does this speed and descent rate look right?
I took this off the forum of my local airport, it's in the movements thread where guys track incomings and outgoings on the SBS thingies. I've removed the airline and specific airport but I just wanted to ask whether you who know what you're doing (I'm SLF!) think the descent rate and speed for the given altitude look a litle excessive? Maybe I should tell the guy to get his SBS recalibrated!
Altitude : 1798 m - 5899 ft
Ground Speed : 540 km/h - 336 mph - 292 knots
Vertical Speed : -819 m/min - -2687 ft/min (DESCENT)
