 Due to the low level of CTA at these aerodromes, it is best practice to give airways clearance to aircraft at the holding point, to ensure departing aircraft can have uninterrupted climb.

+## Departure Procedures
+Aircraft departing the TMA to the south planned at `F130` or above will likely leave and re-enter CTA on climb. These aircraft should be instructed to leave and re-enter on climb to the standard assignable level (or other level as appropriate).

+!!! example
+    **PHD**: "RXA2125, leave and re-enter controlled airspace on climb to F180, no reported IFR traffic"  
+    **RXA2125**: "Leave and re-enter controlled airspace on climb to F180, RXA2125"
 
+## Airspace Division
 The divisions of the airspace between **PHA**, and **PHD** change based on the Runway Mode.
