I'm with SM4 ....
SARTIME .... held by ATS, normally for arrival at an aerodrome
FLIGHT NOTE ... can be held by anyone, normally for arraival at an aerodrome
SARWATCH ... Search And Rescue WATCH, based on continuous 2 way communications ... provided by ATS. For it to exist, there has to be an ATS Officer there, AND, you must be able to maintain 2-way continuous communications with him/her. If you are in a TIBA area, it is likely that you are only in range of the frequency that is normally guraded by that Sector Controller ... who ain't there. No one is watching your blip or ensuring that you answer all calls. A SARWATCH cannot exist.
Having said that, if you got into trouble and were able to raise another sector on the radio, they would certainly provide you with any assistance they could.
P.S. No one can hear you yell in space !
