"Definitely  more than one way to view this topic.  As a controller only/non-flyer (on Vatsim), I send contactme to everyone who enters or is in the sector.  The amount of time it takes for a response varies widely.  I know the 30 min rule and I can not count how many times its been broken (I rarely wallop someone, especially for failure to answer).  Many seem to get online and leave the flight deck for other chores, possibly hoping that no one contacts them and the flight is completed for credit in their VA.   Clearly not everyone is in this category, but more often times than not, it is hard reach (voice) the pilot. \n \n\n\n\tOn another note, for those who do answer the call (or contact the controller themselves), kudos to them for proper procedure.   The only other comment/complaint I will voice is to maintain vigilance to the radio once in contact.  Particularly given the traffic count Vatsim is experiencing under the present environment.  The pilot only has a single (there own) aircraft call to worry about, controllers can have many, many more.  When you  fail to respond to a call (handoff, turn, altitude change to meet LOA or traffic, etc.), it places an incredible amount of extra, unnecessary workload, on the ATC controller.  Technically we have to coordinate with others because you aren't \"there\".  When a enroute controller is operating solo, their job can cover hundreds of miles, many hats, (clearance delivery, local ground, tower, departure/arrival), and at multiple airfield; all while controlling enroute aircraft and having the pleasure of a pilot who walks away from their radio. :(.\n \n"
