While on the ground at day south I received my instrument clearance from day departure via radio/land line communications. I read the clearance back and was told readback correct. The controller then proceeded to talk to someone else. There were no departure restrictions in the clearance. Approximately 1 min later I departed. Another minute later I contacted day departure and the controller asked 'who released you?' from this question I assume the controller was not expecting me to depart but was expecting me to hold for release. Paragraph 323 of the aim states that a controller may assign departure restrictions when necessary. In this instance no departure restrictions were given. Paragraph 270 of the aim states, 'when ATC issues a clearance or instruction pilots are expected to execute its provisions upon receipt.' I had my clearance with no departure restrictions so I executed my clearance and departed. At this point I don't feel that I have done anything in violation of the far's or aim. However, there was a pilot/controller communication problem. I feel that the aim should be amended to require a radar release, active/void time, release time, or the statement 'contact departure on (frequency) when airborne' when departing an uncontrolled field on an instrument flight plan. This should help enforce pilot/controller xchking during communications. From now on I will always check first.
Original NASA ASRS Text
Title: NO DEP RESTRICTIONS ISSUED.
Narrative: WHILE ON THE GND AT DAY S I RECEIVED MY INSTRUMENT CLRNC FROM DAY DEP VIA RADIO/LAND LINE COMS. I READ THE CLRNC BACK AND WAS TOLD READBACK CORRECT. THE CTLR THEN PROCEEDED TO TALK TO SOMEONE ELSE. THERE WERE NO DEP RESTRICTIONS IN THE CLRNC. APPROX 1 MIN LATER I DEPARTED. ANOTHER MINUTE LATER I CONTACTED DAY DEP AND THE CTLR ASKED 'WHO RELEASED YOU?' FROM THIS QUESTION I ASSUME THE CTLR WAS NOT EXPECTING ME TO DEPART BUT WAS EXPECTING ME TO HOLD FOR RELEASE. PARAGRAPH 323 OF THE AIM STATES THAT A CTLR MAY ASSIGN DEP RESTRICTIONS WHEN NECESSARY. IN THIS INSTANCE NO DEP RESTRICTIONS WERE GIVEN. PARAGRAPH 270 OF THE AIM STATES, 'WHEN ATC ISSUES A CLRNC OR INSTRUCTION PLTS ARE EXPECTED TO EXECUTE ITS PROVISIONS UPON RECEIPT.' I HAD MY CLRNC WITH NO DEP RESTRICTIONS SO I EXECUTED MY CLRNC AND DEPARTED. AT THIS POINT I DON'T FEEL THAT I HAVE DONE ANYTHING IN VIOLATION OF THE FAR'S OR AIM. HOWEVER, THERE WAS A PLT/CTLR COM PROB. I FEEL THAT THE AIM SHOULD BE AMENDED TO REQUIRE A RADAR RELEASE, ACTIVE/VOID TIME, RELEASE TIME, OR THE STATEMENT 'CONTACT DEP ON (FREQ) WHEN AIRBORNE' WHEN DEPARTING AN UNCONTROLLED FIELD ON AN INSTRUMENT FLT PLAN. THIS SHOULD HELP ENFORCE PLT/CTLR XCHKING DURING COMS. FROM NOW ON I WILL ALWAYS CHK FIRST.
