I think that Don said it best in his analysis. A few things to consider and think about.
1.) We are quick to want to change because of what our real world counterparts do, yet sometimes in wanting to make said change we forget to analyze the things that we cannot simulate for whatever reason; more importantly we sometimes forget to see how the change that we want will impact the change that we cannot make thus creating a new problem.
2.) From our current Division Policy
6.6.2.
VATUSA controllers have the right to approve and allow special procedures for aircraft under their
control, in alignment with
ARTCC
6.6.3.
Controllers may, and traffic permitting are encouraged to, allow pilots to simulate reasonable
emergencies. However, as specified in section B8 of the VATSIM Code of Conduct, a controller may
decline to allow, or direct the termination of, any simulated emergency
3.) COC B8 Pilots are permitted to declare in-flight emergencies only when under positive air traffic control. If there is no air traffic controller providing services to the pilot and surrounding traffic, declaring an in-flight emergency is not permitted. If, for any reason, air traffic control requests the pilot to terminate the emergency, then the pilot must do so IMMEDIATELY or log off of VATSIM. Pilots are not permitted to simulate, in any manner, an unlawful act while logged onto the VATSIM.net network including, but not limited to, declaring a hijack by statement utilizing either voice or text or by entering a transponder code of 7500.
The question is, is attempting to reach a NORDO pilot acceptable under this "emergency" clause, or should we stick to using the .contactme PM and UNICOM to attempt to reach an otherwise unresponsive a/c?
For purposes of VATSIM etc. I do not think that a NORDO pilot constitutes an emergency. I am not going to say what I think it constitutes but any emergency that a pilot may have should be approved or at the discretion of the online ATC controller. That being said using the Guard Frequency. "Let Your Conscious Be Your Guide".
