Visual Approach

Share
Subject to the conditions in 2.3.4.3, clearance for an IFR flight to execute a visual approach may be requested by a flight crew or initiated by SHE APP. In the latter case, the concurrence of the flight crew shall be required, using the following examples of phraseology :

a) [C/S] [(instructions) MAINTAIN BELOW 2 000] CLEARED [FOR] VISUAL APPROACH RUNWAY 34L REPORT AERODROME IN SIGHT; or
b) [C/S] CLEARED [FOR] VISUAL APPROACH TO SEAHORSE REPORT AERODROME IN SIGHT

When the flight crew of an aircraft request to execute a visual approach but the weather condition is likely impossible to approve the request, SHE APP may inform using phraseology : [C/S] WEATHER NOT AVAILABLE or VERIFY THAT YOU HAVE THE (airport) WEATHER.

Note.— Since SHE APP has also the responsibility to control aircraft intend to land at Brightstar and Tigerfort, visual approach may be given to those aircraft.
                                                              
SHE APP shall exercise caution in initiating a visual approach when there is reason to believe that the flight crew concerned is not familiar with the aerodrome and its surrounding terrain. SHE APP should also take into consideration the prevailing traffic and meteorological conditions when initiating visual approaches.

 An IFR flight may be cleared to execute a visual approach provided the pilot can maintain visual reference to the terrain and:
a) the reported ceiling is at or above 3 000 feet; or
b) the pilot reports at 3 000 feet or at any time during the instrument approach procedure that the meteorological conditions are such that with reasonable assurance a visual approach and landing can be completed.

Separation shall be provided between an aircraft cleared to execute a visual approach and other arriving and departing aircraft.

For successive visual approaches, separation shall be maintained by SHE APP until the pilot of a succeeding aircraft reports having the preceding aircraft in sight. The aircraft shall then be instructed to follow and maintain own separation from the preceding aircraft.

When both aircraft are of a heavy wake turbulence category, or the preceding aircraft is of a heavier wake turbulence category than the following, and the distance between aircraft is less than the appropriate wake turbulence minimum, SHE APP shall issue a caution of possible wake turbulence.
Example of phraseology :

[C/S] YOU ARE FOLLOWING A BOEING 747, 12 O'CLOCK
The pilot-in-command 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 SHE APP accordingly, stating their requirements.

Transfer of communications to SHE TWR should be effected when the flight crew has reported runway in sight or has established visual contact.
