RNAV STAR
General notes
- only used by aircraft equipped with FMS or GPS
- RNAV STARs must be retrievable by the procedure name from the aircraft database and conform to charted procedure.
- expected altitudes and airspeeds are not part of the clearance until ATC includes them verbally
- does not have the force of a clearance until issued specifically by ATC
- Multiple procedures may exist to accommodate GPS receivers and FMS, both with and without VNAV capability. Each procedure name incorporates a letter of the alphabet, starting with Z and working backward through Y, X, W, and so on.
"...cleared for the RNAV (RNP) Zulu approach, Runway 15R...”
instrument approaches in use may not be provided (ATIS or ATC) when the visibility is 3 SM or better and the ceiling is at or above the highest initial approach altitude established for any instrument approach
- An RNAV STAR or STAR transition typically includes flyby waypoints, with fly over waypoints used only when operationally required.
- designed, coordinated, and approved by a joint effort between air carriers, commercial operators, and the ATC facilities that have jurisdiction for the affected airspace
designated as either RNAV 1 or RNAV 2, based on
- aircraft navigation equipment required
- flight crew procedures
- the process and criteria used to develop the STAR
RNAV 1
- higher equipment requirements
- tighter required navigation performance (RNP) tolerances
- generally designated for high-traffic areas
Clearance variations
“cleared HADLY ONE arrival, descend and maintain flight level two four zero”
descend only to the assigned altitude and then maintain that altitude until cleared for further descent.
Use the equipment for both lateral guidance and altitude restrictions, as published on the chart.
“Descend via the HARIS ONE arrival, except cross BRUNO at one three thousand then maintain one zero thousand.”
The pilot should track the arrival both laterally and vertically, descending so as to comply with all altitude and airspeed restrictions until reaching BRUNO, and then maintain 10,000 feet until cleared by ATC to continue to descend.
“Proceed direct MAHEM, descend via the MAHEM TWO arrival.”
intercept a STAR and then use it for both lateral guidance and altitude restrictions
