ARTCC providing approach control services
Contract Class D VFR ATCT
VMC at airport (severe clear for argument's sake)
- At what point does a VFR tower apply visual separation for successive IFR arrivals?
- Is it possible to be other than one-in-one-out for successive IFR arrivals?
- Does this need to be in an LOA?
- If not in an LOA, can this be authorized in a pinch?
It just seems like a grey area for when center responsibility for IFR separation ends, and tower begins.
Curious about input from tower guys...
Looking at .65 5-9-5 Approach Separation Responsibility
Combined with .65 7-2-1 Visual Separationa. The radar controller performing the approach control function is responsible for separation of radar arrivals unless visual separation is provided by the tower, or a letter of agreement/facility directive authorizes otherwise. Radar final controllers ensure that established separation is maintained between aircraft under their control and other aircraft established on the same final approach course.
The radar controller may be a controller in an ARTCC, a terminal facility, or a tower controller when authorized to perform the approach control function in a terminal area.
c. Nonapproach control towers may be authorized to provide visual separation between aircraft within surface areas or designated areas provided other separation is assured before and after the application of visual separation. This may be applied by the nonapproach control tower providing the separation or by a pilot visually observing another aircraft and being instructed to maintain visual separation with that aircraft.
