d.
USE OF STANDARD INSTRUMENT DEPARTURES (SIDs) - Standard Instrument Departure (SID) procedures are available at most military and joint civil/military airports. All pilots are encouraged to use SIDs provided no flight derogation will ensue. After a SID is accepted in the air traffic clearance, the pilot will conform to exact routings, altitudes, and specific restrictions shown on the departure chart or received from the air traffic controller. Except for Radar vectors, route amendments to the published procedures will not be accepted unless the entire procedure is issued verbatim.

(1)
After an aircraft is established on a SID and subsequently is Radar vectored or cleared off of the SID/SID TRANSITION, pilots shall consider the SID cancelled, unless the controller adds "expect to resume SID".

e.
DEPARTURE RADAR - Normally aircraft will be cleared out of the Terminal Area utilizing SIDs via radio navigation aids. When a pilot is given a vector taking his aircraft off a previously assigned non-Radar route, he will be advised briefly what the vector is to achieve. Thereafter, Radar service will not be terminated until the aircraft has been re-established "on-course" using an appropriate navigation aid and the pilot has been advised of his position. When a flight has a malfunctioning directional gyro, the pilot will be advised, prior to issuance of vectors, to make all turns at the standard rate and to execute turns immediately upon receipt of instructions.

f. ADHERENCE TO AIR TRAFFIC CLEARANCE

(1)
When an air traffic clearance has been obtained under either VFR or IFR, the pilot in Command of the aircraft shall not deviate from the provisions thereof unless an amended clearance is obtained. The addition of a VFR restriction does not authorize a pilot to deviate from the route of flight or any other provisions of the Air Traffic Control clearance.

(2)
The most important and guiding principle to remember is that the last Air Traffic Control clearance has precedence over the previous Air Traffic Control clearance. When the route or altitude in a previously issued clearance is amended, the controller will restate applicable altitude restrictions. If previously issued altitude restrictions are omitted from an amended clearance, those altitude restrictions are cancelled. Pilots should always request route/altitude verification from Air Traffic Control if any portion of a clearance is not completely understood.

NOTE: When an aircraft is vectored off a previously assigned route, the controller is required to inform the pilot of the airway, route or point to which the aircraft is being vectored.

(3)
Should a pilot for any reason be incapable of complying with any provision of an issued Air Traffic Control clearance or restriction added thereto, he is expected to immediately advise Air Traffic Control. A brief reason, such as, "Unable Account of Load", may be included if considered necessary. He may then expect an amended Air Traffic Control clearance.

g.
ENROUTE CLEARANCE - If it becomes necessary for a pilot to deviate from an approved route or altitude/Flight Level when on an IFR flight plan, it is important that the request for deviation be forwarded to Air Traffic Control as far in advance as possible. Delay in submitting the request, or inability to do so, may delay or even preclude, Air Traffic Control approval of the request, or require that additional restrictions be placed on the clearance.

(1)
If thunderstorm conditions are of such severity that an immediate deviation from course and/or altitude/Flight Level is necessary and time will not permit approval by Air Traffic Control, the pilot's emergency authority may be exercised. However, when time permits, the following information should be furnished to Air Traffic Control when requesting clearance to detour thunderstorm activity.

(a) Point at which detour will commence.
