b) the ground visibility is not below the AOM of non -precision approach available at the aerodrome and which aircraft is capable of carrying out at the time visual approach is requested.
or if visual approach is requested for a runway which has only circling approach, the ground visibility is not less than 5 km.
15.2.
The pilot shall advise the controller immediately when, a) Weather has deteriorated and unable to keep the terrain in sight; or b) Unable to continue flight following the preceding aircraft; or c) Additional spacing is required from preceding aircraft.

Instrument Approach completed by Visual reference
An instrument approach may be completed with the help of visual references subjected to the following:
i) Clearance for an IFR flight to execute a visual approach may
be requested by the pilot or initiated by the controller.
ii) If the controller has initiated the visual approach and it is not
acceptable to the pilot, the pilot shall advise the controller that
visual approach not acceptable.
iii) When clearance to execute visual approach has been issued, it
shall be the responsibility of pilot to maintain terrain clearance.
iv) The PIC of the aircraft concerned shall be responsible for
ensuring that the spacing from a preceding aircraft of a heavier
wake turbulence category is acceptable. If it is determined that
additional spacing is required, the flight crew shall inform the
ATC unit accordingly, stating their requirements.
v) The pilot at the time of requesting for visual approach should
give position report.
Pg-14/28
vi) The controller should endeavor to sight the aircraft and upon sighting should inform the pilot so that the landing clearance is issued thereafter.
17 Stabilised Approach
A Stabilised Approach consists of accomplishing the following no later than 1000ft AGL on a Instrument Approach and no later than 500ft AGL on a visual approach. In case of non- precision! Circling approach the aircraft should be stabilised be stabilised on establishing the “Required Visual Segment” and leaving MDA.

On profile (ILS glide slope, published non-precision profile, or when a glide path (approach 3 degrees) has been established visually and conditions have been met to allow descent below the DA(DH) or MDA(MDH))
