Vicinity of AD (RAC 4-1)
The vicinity of an AD is defined as an area around an AD where A/C carry out manoeuvres associated with entering, leaving, or operating within a circuit. The actual dimensions of vicinity of AD depend on characteristics of A/C using the airspace.

Conditional line up clearance (RAC 4-12)
-Controller and pilot have conflicting traffic in sight
-no multiple line ups
-A/C or vehicle causing the condition shall be the first movement to pass in front of A/C receiving conditional clearance
-callsign
-the condition
-clearance
-reiteration of the condition
“Behind the landing 737 at 4 mile final, line up runway 28, behind.”
“Behind the ATR taxing behind you left to right, push and start approved, behind.
Multiple line ups criteria (RAC 4-13)

-callsign
-any significant change in MET info
-RWY surface conditions
-other temp hazards such as birds
-special instructions, reporting instructions, or pertinent info
-direction of turn after take-off
-advice of WT
-any qualification (qualified take-off)
-RWY/grass/seal
-“cleared for take-off”
Qualified take-off clearance (RAC 4-15)
-day
-5km vis
-reasonable assurance that appropriate RWY sep will exist when departing A/C commences take-off
-pilot is advised of the preceding departing or landing A/C (or personnel/vehicle crossing/vacating RWY) and will be able to keep it in sight until RWY sep is in place.
-action must be taken by the controller to ensure RWY sep is preserved

“Tomahawk departing ahead, runway 10 cleared for take-off”
Phraseology for expediting take-off (RAC 4-15)
-“Cleared immediate take-off”
-“take-off immediately or vacate RWY” (reason e.g “traffic at 2 miles”)
-“take-off immediately or hold short of RWY” (reason e.g “traffic on short final”)
Phraseology for cancelling take-off (RAC 4-15)
-Prior to commencing take-off roll
“(Callsign) Hold position, cancel take-off I say again cancel take-off”
-After commencing take-off roll
“(Callsign) stop immediately (callsign) stop immediately” followed by nature of emergency
