Answers to TC 9 16 questions 1 a b c f Procedural notes 1 and 2 in the Briefing Strip indicate the requirements for the approach procedure regardless of the IF or IAF used authorization required AR and GPS Ballflag note 1 on the plan view indicates that RF radius to fix legs are required to fly the procedure from LIBYY and ballflag note 2 specifies a minimum RNP value of 040 2 a c d e AC 90 101A Approval Guidance for RNP Procedures with AR indicates that RNP AR procedures with RNP values less than 030 or with RF legs require the use of an autopilot or a flight director FD driven by the RNAV system in all cases The autopilot FD must operate with suitable accuracy to track the lateral and vertical paths required by the RNP AR procedure 3 a AC 90 101A states that a display of the altitude restrictions associated with flightplan fixes must be available to the pilot In addition the equipment must display the FPA flightpath angle associated with any flightplan leg of an RNP AR procedure 4 c d The FAA NOTAM Cold Temperature Restricted Airports indicates that pilots without temperature compensating equipment must calculate and make a manual cold temperature altitude correction to the designated segment s of the approach using the AIM 7 2 3 ICAO Cold Temperature Error Table Jeppesen provides a Cold Temperature Correction Table on a separate chart for the airport so altitude corrections can be made easily On initial contact with the ATC facility issuing the approach clearance pilots must report cold temperature corrected altitudes that apply to an intermediate segment and or a published missed approach final altitude Pilots should not apply cold temperature corrections to ATC assigned altitudes 5 a AC 90 101A states that an operable TAWS is required for all RNP AR procedures The TAWS should use altitude that is compensated for local pressure and temperature effects eg corrected barometric and Global Navigation Satellite System GNSS altitude and include significant terrain and obstacle data 6 c d A different mandatory altitude applies to each IF including 5000 ft MSL at JIMMI and 6000 ft MSL at APISE Ballflag note 1 on the plan view indicates that RF legs are required if flying from LIBYY APISE EKEME or KOLKE Ballflag note 2 shows a required RNP value of 040 at LIBYY and KOLKE 7 c d f g None of the IFs have a published airspeed limitation Ballflag note 3 on the plan view indicates a maximum speed limit of 210 kts at the fixes OYISI INION BUVXE and JODIX which are fixes that precede an RF leg 8 b AC 90 101A states that pilots must not exceed the maximum airspeeds shown in Table 1 throughout the RF leg segment Table 1 indicates that on the initial and intermediate segments of the approach IAF to FAF category A and B aircraft must be at or below 150 KIAS The maximum airspeed for category C D and E aircraft is 250 KIAS on these segments 9 a b The landing minimums section shows a DA of 3163 ft MSL for an RNP value of 015 which is 36 ft lower than 3199 ft MSL using an RNP value of 030 RVR 52 applies when the ALS is out in this case an ALSF II as shown in the lighting box According to AC 90 101A changes to lower RNP values must be complete by the first fix defining the leg with the lower value in this case ISEBE According to AC 20 138D Airworthiness Approval of Positioning and Navigation Systems it is not necessary for navigation dis plays particularly primary flight displays to include an actual navigation performance ANP or RNP accuracy value The display only needs to provide an alert if the RNP value for the specific operation cannot be met The missed approach instructions and icons indicate a climb to 7300 ft MSL on a track of 100 to AYDOK and then on a track of 122 to CANEK A direct entry would be recommended for entering the hold at CANEK on a course of 115 and 7 nm legs are shown RNP AR missed approaches are typically designed to require RNP 10 If the missed approach requires an RNP value less than 10 the approach chart will include the following note Missed approach requires RNP less than 10 10 c
