MATS Pt 1 SI 6 of 99
The use of FMS waypoints to assist aircraft approaching an aerodrome.
Quote:
"It is not the intention of this insruction to prevent controllers from permitting pilots to self position to final approach. However, in authorising this manoeuvre, controllers should bear in mind that the vertical and horizontal profile the aircraft will fly is not completely predictable and, therefore, should exercise the same caution they would when approving a visual approach."
"...the Authority requires controllers to adhere to the following rules when approving use of such approaches:
1 Aircraft are to be allocated levels in accordance with MATS Pt 1 and 2.
2 Controllers, especially those providing a radar service, are reminded of their responsibilities with regard to terrain clearance...
3 Controllers are not to initiate reference to "Centrefix" or other locally used terms.
4 If controllers are in any doubt about the location of the "Centrefix" or other position referred to by a pilot, they are to ask the pilot to define this position and take this definition into account when carrying out their controlling duties."
All bases covered, take care now!
