Not sure if this is fit for #live, tell me if im supposed to move it
Tagging along from this topic about issues related to dissappearing planes
Today while approaching TNCM, and entering the GPS cone i noticed a very slow flying B763 ahead of me so i slowed down to match his speed and maintain separation.
Maybe 1-2 minutes later he completely dissappeared, along with a few other planes in the area. I maintained speed, thinking that it was just the airplane dot dissapearing.
But when i got to a 3-4nm final, and the plane still wasnt there, i sped up from slowest practical speed (since traffic was crazy and i didnt want to hold up the queue, i thought he disconected)
Less than a mile from the threshold, the dot reappeared and i realised the plane was still slowing down, and had yet to backtaxi to vacate the runway and i soon promptly got a go around.
My two questions are:
Do you have any tips to mitigate such issues, and situations?
Whats the deal with airplane dots anyway (ie. why its always changing which planes are shown, why can i see pmanes that are 200nm away but not all that are 5nm next to me), and is there a way to fix this issue (context below)
(Context for 2.) - same flight, while still approaching TNCM at 50nm out i can see some of the planes lining up at the end of the GPS cone, then holding around the airport - i suddenly see every plane on the ground, but half of the airbourne planes are gone, on the downwind leg - planes in sequence with me appear, then dissappear again, and finally what happened on final is listed above
