(ADS-C) logon, pilots should discontinue voice position reports. ATC will inform pilots that they are in “radar contact”: (e) Change in the average true airspeed (at cruising altitude) when it varies by 5 percent or 10 knots (whichever is greater) from that filed in the flight plan. (f) The time and altitude or flight level upon reaching a holding fix or point to which cleared. (g) When leaving any assigned holding fix or point. The reports in subparagraphs (f) and (g) may be omitted by pilots of aircraft involved in instrument training at military terminal area facilities when radar service is being provided. (h) Any loss, in controlled airspace, of VOR, TACAN, ADF, low frequency navigation receiver capability, GPS anomalies while using installed IFR − certified GPS/GNSS receivers, complete or partial loss of ILS receiver capability or impairment of air/ground communications capability. Reports should include aircraft identification, equipment affected, degree to which the capability to operate under IFR in the ATC system is impaired, and the nature and extent of assistance desired from ATC. 1. Other equipment installed in an aircraft may effectively impair safety and/or the ability to operate under IFR. If such equipment (e.g., airborne weather radar) malfunc- tions and in the pilot’s judgment either safety or IFR capabilities are affected, reports should be made as above. 2. When reporting GPS anomalies, include the location and altitude of the anomaly. Be specific when describing the location and include duration of the anomaly if necessary. (i) Any information relating to the safety of flight. 5 − 3 − 3. Additional Reports a. The following reports should be made to ATC or FSS facilities without a specific ATC request: 1. At all times. 2. When not in radar contact. (a) When leaving final approach fix inbound on final approach (nonprecision approach) or when NOTE − NOTE − (a) Identification; (b) Position; (c) Time; (d) Altitude or flight level (include actual altitude or flight level when operating on a clearance specifying VFR − on − top); (e) Type of flight plan (not required in IFR position reports made directly to ARTCCs or approach control); (f) ETA and name of next reporting point; (g) The name only of the next succeeding reporting point along the route of flight; and (h) Pertinent remarks. d. Position Report Items: 1. Position reports should include the follow- ing items: En Route Procedures 5 − 3 − 15 (a) When vacating any previously assigned altitude or flight level for a newly assigned altitude or flight level. (b) When an altitude change will be made if operating on a clearance specifying VFR − on − top. (c) When  unable  to climb/descend at a rate of a least 500 feet per minute. (d) When approach has been missed. (Re- quest clearance for specific action; i.e., to alternative airport, another approach, etc.) NOTE − (a)  when their aircraft is initially identified in the ATC system; and (b)  when radar identification is reestablished after radar service has been terminated or radar contact lost. Subsequent to being advised that the controller has established radar contact, this fact will not be repeated to the pilot when handed off to another controller. At times, the aircraft identity will be confirmed by the receiving controller; however, this should not be construed to mean that radar contact has been lost. The identity of transponder equipped aircraft will be confirmed by asking the pilot to “ident,” “squawk standby,” or to change codes. Aircraft without transponders will be advised of their position to confirm identity. In this case, the pilot is expected to advise the controller if in disagreement with the position given. Any pilot who cannot confirm the accuracy of the position given because of not being tuned to the NAVAID referenced by the controller, should ask for another radar position relative to the tuned in NAVAID.
