.rcva Radar Contact,$dist($arr) miles $bear($arr) of $arr at $calt, expect vectors for the visual approach RWY $1, altimeter $altimeter($arr)
The above is a typical radar contact and informs the pilot to expect a visual approach.
The construction of the Alias above is described as follows:
.rcva is the [dot] command which can be anything that you want to use to identify the message in the Alias. I have used .rcva which identifies as a “ radar contact visual approach” solely for my own personal purpose – it can be replaced with something that you want to use for this purpose.
The $dist($arr) instructs the programme to detect and reveal the distance between a POINT (could be an airport, NDB, VOR or intersection (INT)) and the aircraft. In this instance it is the ($arr) arrival airport. The $bear($arr) instructs the programme to determine the direction between the aircraft and the POINT. Again, this is the ($arr) arrival airport. The $calt detects the current altitude of the aircraft. The $arr - on its own - confirms the identity of the POINT to be measured by the previous parameters distance $dist and bearing $bear. $1 should be replaced in the VCR Command Line with the runway to be used for the visual approach – like 16C. The $altimeter($arr) instructs the programme to automatically select the Altimeter setting for the $arr arrival airport.
The resulting message received by the pilot should look like this:
“Radar Contact, 15 miles south of ksea at 13500, expect vectors for the visual approach RWY 16C, altimeter 3021”
Happy controlling
