SRA - PAR.
In order to perform an approach SRA (Surveillance Radar Approach), on the radar screen must indicate the final approach path and distances from the point of contact, usually in the form of "VIDEO MAP".
In addition, the controller must be in possession of information which the value of the OCA/H, levels and suggested the crossing of various distances.
Although an approach SRA will never reach the accuracy of the PAR, the controller will have groped to position the aircraft as close as possible to the end, using a technique of control over the azimuthal plane similar to that used by the controllers radar precision.
Below is the phraseology used by controllers and pilots.
The aim is to give pilots the option of partaking in the evolution of the procedure and make the right adjustments to get home even if the weather is adverse.
I wish everyone to have fun.
P= Pilot / C= Controller.
SRA.
P/ Mogadishu precision g.evening this is CFC-031
C/ CFC-031 Mog.Precision reading you 5 go ahead
P/ Reading you 4 position 10nm south...heading...4000ft..request SRA.
C/ CFC 031 Roger sq. ident on 4401.
C/ CFC-031 Radar identified continue on present heading (or turn left/right heding...) this will be vectoring for Surveillance Radar App rwy...terminating at 1/2 miles from touch down, obstacle clearance altitude 500ft, qnh 1014 check your mininma.
P/roger
C/ CFC-031 Mogadishu Precision, when on final maintain 3° glide path and if no trasmission received for 30 seconds during the pattern, or 5 seconds or more when on final proceide visually or instrumental (final tacan,vor,ils and so on), in case of go around climb 4000ft on rwy heding and expect furter vectoring by radar.
P/ roger
C/ CFC-031 turn left heding ...for dw/base
P/ heding ...
C/ CFC-031 turn left/right heding ... shortly on final

C/ 12 nm from touch down, descend to 2500ft
P/ roger, descending to 2500ft.

P/ Heading ...
C/ 8nm from t.down, on course
C/ 7nm form t.down maintain the heading, prepare to start descend in 1 mile.
C/ 6nm from t.down
C/ Entering on precision screen, from this moment do not acknowledge further trasmisson unless requested.
P/ Roger
C/ 5nm from t.down turn left / right heading ... altitude should be......ft, check gear down.
P/ gear down and locked
C/ roger, 4nm from t.down altitude should be .....ft maintain heding ....cleared to land rwy....wind from...../...kts. - acknowledge.
P/ roger cleared to land rwy....
C/ 3nm to t.down, altitude should be ....ft
C/ 2 miles from t.down turn left/right heading ....altitude should be....ft.
C/ 1 mile from t.down altitude should be ....ft, approach terminated report rwy in sight.
P/ Rwy in sight S.R.A radar is terminated continue visually, Mogadishu precision is standing - by.
