(2)
INITIAL RADIO CONTACT - Pilots in their initial radio communication with the facility concerned will state: AIRCRAFT IDENTIFICATION, LOCATION ON THE AIRPORT, TYPE OF OPERATION PLANNED (IFR), POINT OF FIRST INTENDED LANDING AND REQUESTED ACTION (TAXI/CLEARANCE ON REQUEST/ETC.).

(3)
TAXI INSTRUCTION READBACK - Pilots will acknowledge by readback all runway assignment and hold short instructions.

(4) IFR CLEARANCE ITEMS - IFR Clearances to
departing aircraft are issued prior to take-off and will include the following items as appropriate, in order listed:
(a)  Aircraft identification. 
(b)  Clearance limit. 
(c)  Departure procedure or SID. 

(d)
Route of flight.

(e)
Altitude data in the order flown.

(f) USAF: When an airborne aircraft is being issued a Clearance containing an altitude assignment by USAF Air Traffic Controllers, no more than one of the following will be included in the same transmission:
1 Frequency change.
2 Transponder change.
3 Heading.
4 Altimeter setting.
5 Traffic information containing an altitude.
6 Holding instructions.
7 Any special information.
8 Frequency and beacon information.
b. ABBREVIATED IFR DEPARTURE CLEARANCE - Air Traffic Control may issue Abbreviated IFR Clearances which will not include all of the information of a Detailed Clearance. However, an Abbreviated Clearance cannot be issued or accepted if the route of flight originally filed with Air Traffic Control has been changed by the pilot. In this case, the pilot will request a Detailed Clearance be issued by Air Traffic Control. An Abbreviated Clearance will not be issued when a pilot requests a Detailed Clearance.
(1)
When operating in a Radar environment, Air Traffic Control will issue the Abbreviated Clearance as follows:

(a)
If a Standard Instrument Departure is assigned: "CLEARED TO (destination) AIRPORT; (SID name and number) DEPARTURE, (transition name) TRANSITION; THEN, AS FILED. MAINTAIN (altitude); and, if required, additional instructions or information".

(b)
If a Standard Instrument Departure is not assigned: "CLEARED TO (destination) AIRPORT AS FILED. MAINTAIN (altitude); and, if required, additional instructions or information."

(2)
When operating in a non-Radar environment, Air Traffic Control will specify one, two, or more fixes as necessary to identify the initial route of flight. "CLEARED TO (destination) AIRPORT AS FILED VIA NOTTINGHAM, PATUXENT. MAINTAIN (altitude)".

(3)
When a filed route will require minor revisions Air Traffic Control will note the revision by stating "except change route to read" follow by the amended route portion. "CLEARED TO (destination) AIRPORT (SID and SID transition, as required); THEN AS FILED EXCEPT CHANGE ROUTE TO READ (amended

route portion). MAINTAIN (altitude); and, if required additional instructions or information".
(4)
ALTITUDE AMENDMENTS - If a controller restates a previously issued altitude to "MAINTAIN", it is considered an amended clearance. When previously issued altitude restrictions are omitted from the "amended clearance", the altitude restrictions are cancelled.

(5)
"CLEARANCE READBACK" - There is no requirement for pilots to readback Air Traffic Control clearances while on the ground (except runway assignment and hold short instructions); however, pilots should clarify any portion of clearance that is not completely understood. In addition, controllers may request pilots to readback any clearance.

c.
CLEARANCE LIMIT - Initial clearances will include whenever practicable, the destination airport as the clearance limit.  However, Air Traffic Control may utilize short range clearance procedures, in lieu of a clearance to destination airport. When any part of the route beyond the short-range clearance limit differs from that specified in the original flight plan, clearance will include the proposed routing beyond said clearance limit. When a flight has been cleared to a fix short of the filed destination, additional clearance to proceed beyond or instructions to hold at such fix, whichever is appropriate, will be issued at least 5 minutes before aircraft is estimated to reach the fix. If further clearance has not been received, hold in accordance with holding procedures paragraph as discussed later in this chapter. Flights conducted in accordance with IFR for the initial part of the flight and VFR for subsequent portions will be cleared to the fix at which the IFR portion of the flight terminates.
