Clearence delivery (CD)

IFR clearance

When starting an IFR flight, the Clearance controller is the first person a pilot must contact before pushback/start/taxi. He will then issue you a set of instructions in relation to your flight plan.

A clearance will usually contain these things:

1. Destination airport

2. Departure route (SID or heading)

3. Altitude/Flight level

4. QNH

5. Squawk code

 

 

An example of initial Pilot contact who has filed the following flight plan:

EGBB EGLC IFR FL90 (No SID filed here, he’s departing on ATC Vectors)

Pilot: “Birmingham Delivery, BAW232U. Type 737 at stand 55. Information Charlie on board, QNH 1010. Requesting Clearance as filed”

Controller: “BAW232U, I have your clearance. Ready to copy?”

Pilot: “Ready to copy, BAW232U”

ATC: “BAW232U, Cleared to London City as filed. After departure fly runway heading, climb altitude 5000ft. QNH 1010. Squawk 5436″

Pilot: ” Cleared to London City as filed. After departure fly runway heading, climb altitude 5000ft. QNH 1010. Squawk 5436. BAW232U”

ATC: BAW232, readback correct. Contact ground 121.80 when ready for push and start”

 

For a SID Departure:

Flight plan: EGBB EGLC IFR FL190 DTY3E BNN

(So, the pilot is flying from Birmingham to London City, IFR. He wants to cruise at Fl190 and depart via the DTY3E departure. His waypoint after that is the Bovingdon VOR)

 

Pilot: “Birmingham Delivery, BAW232U. Type 737 at stand 55. Information Charlie on board, QNH 1010. Requesting Clearance as filed”

Controller: “BAW232U, I have your clearance. Ready to copy?”

Pilot: “Ready to copy, BAW232U”

ATC: “BAW232U, Cleared to London City as filed. DTY3E departure. QNH 1010. Squawk 5436″

Pilot: ” Cleared to London City as filed. DTY3E departure. QNH 1010. Squawk 5436. BAW232U”

ATC: BAW232, readback correct. Contact ground 121.80 when ready for push and start”

 

VFR traffic is different. All VFR traffic will get clearance at the hold for the runway, usually from a Tower controller. In the odd instance, a delivery or ground controller may issue the clearance.

Here is a short example:

VFR Departure (out of zone):

[Aircraft callsign] [your callsign], Hold Position. Cleared to leave the control zone VFR via (VRP/VOR/N,E,S,W boundary) Not above altitude [altitude] QNH [QNH] Squawk 7000.

 

VFR Departure (Joining VFR Circuit):

[Aircraft callsign] [your callsign] Hold position. Cleared [Left/Right] hand VFR circuit. Runway [Rway in use]. Not Above [altitude/flight level]. QNH [QNH]. Squawk 0406

There are a few extra things when considering VFR clearances. This will be explained a little later on in the course. For more information on communications, visit the ATC Conversation Section
