Order 7110.65P, Air Traffic Control, with changes

7110.65P CHG 18/5/04f. When the “pilot’s discretion” portion of aclimb/descent clearance is being canceled by assigninga new altitude, inform the pilot that the newaltitude is an “amended altitude.”EXAMPLE−“American Eighty Three, amend altitude, descend andmaintain Flight Level two six zero.”NOTE−American Eighty Three, at FL 280, has been cleared todescend at pilot’s discretion to FL 240. Subsequently, thealtitude assignment is changed to FL 260. Therefore, pilot’sdiscretion is no longer authorized.g. Altitude assignments involving more than onealtitude.PHRASEOLOGY−MAINTAIN BLOCK (altitude) THROUGH (altitude).h. Instructions to vertically navigate on a STAR/RNAV STAR/FMSP with published restrictions.PHRASEOLOGY−DESCEND VIA (STAR/RNAV STAR/FMSP name andnumber)TERMINAL: DESCEND VIA (STAR/RNAV STAR/FMSPname and number and runway number).EXAMPLE−“Descend via the Mudde One Arrival.”“Cross JCT at flight level two four zero, then descend viathe Coast Two Arrival.”TERMINAL: “Descend via the Lendy One Arrival,Runway 22 left.”NOTE−Clearance to “descend via” authorizes pilots:1. To vertically and laterally navigate on a STAR/RNAVSTAR/FMSP.2. When cleared to a waypoint depicted on a STAR/RNAVSTAR/FMSP, to descend from a previously assignedaltitude at pilot’s discretion to the altitude depicted for thatwaypoint, and once established on the depicted arrival, tonavigate laterally and vertically to meet all publishedrestrictions. ATC is responsible for obstacle clearancewhen issuing a “descend via” clearance from a previouslyassigned altitude.REFERENCE−FAAO 7110.65, Minimum En Route Altitudes, Para 4−5−6.FAAO 7110.65, Separation From Obstructions, Para 5−5−9.NOTE−3. Pilots navigating on a STAR/RNAV STAR/FMSP shallmaintain last assigned altitude until receiving clearance to“descend via.”4. Pilots cleared for vertical navigation using thephraseology “descend via” shall inform ATC upon initialcontact.EXAMPLE−“Delta One Twenty One leaving FL 240, descending viathe Civit One arrival.”REFERENCE−AIM, Standard Terminal Arrival (STAR), Area Navigation (RNAV) STAR,and Flight Management System Procedures (FMSP) for Arrivals,Para 5−4−1a2.1. Assign an altitude to cross the waypoint/fix,if no altitude is depicted at the waypoint/fix, foraircraft on a direct routing to a STAR/RNAVSTAR/FMSP.EXAMPLE−“Proceed direct Luxor, cross Luxor at or above flight leveltwo zero zero, then descend via the Ksino One Arrival.”2. A descend via clearance shall not be usedwhere procedures contain published “expect”altitude restrictions.NOTE−Pilots are not expected to comply with published “expect”restrictions in the event of lost communications, unlessATC has specifically advised the pilot to expect theserestrictions as part of a further clearance.3. If it is necessary to assign a crossing altitudewhich differs from the STAR/RNAV STAR/FMSPaltitude, emphasize the change to the pilot.PHRASEOLOGY−DESCEND VIA THE (STAR/FMSP) ARRIVAL EXCEPTCROSS (fix, point, waypoint) (revised altitudeinformation).EXAMPLE−“United 454 descend via the Haris One Arrival, exceptcross Haris at or above one six thousand.”NOTE−The aircraft should track laterally and vertically on theHaris One Arrival and should descend so as to cross Harisat or above 16,000; remainder of the arrival shall be flownas published.4. If it is necessary to assign an interim altitude,or assign a final altitude not contained on aSTAR/RNAV STAR/FMSP, the provisions ofsubpara 4−5−7h may be used in conjunction withsubpara 4−5−7a.PHRASEOLOGY−DESCEND VIA THE (STAR/RNAV STAR/FMSP)ARRIVAL EXCEPT AFTER (fix) MAINTAIN (revisedaltitude information).EXAMPLE−“United 454 descend via the Haris One Arrival, exceptafter Bruno, maintain one zero thousand.”4−5−6Altitude Assignment and Verification
