For those who like to keep sharp,or just refresh their skills,if you are watchers on `ads-b`..pick an airliner,and `click``on it. the sidebar will come up with the aircraft`s performance,IAS /G /SPEED.HEIGHT .TEMPERATURE AND WIND,HDG/TRACK..put the numbers onto your `Confuser`,and see if you come up with `what the aircraft is doing, or work it all backwards....
not sure if it works on fltradar24....
