(b) Each IFPDSP is responsible for all elements of the validation and must document their proposed validation activities in a plan and submit as early as possible to the President for acceptance.
(c) The following IFPs do not require flight validation if it can be shown that current obstacle data meets the design requirements of the IFP: (1) En-route or instrument arrival procedures, unless— (i) There is doubt regarding navigation system coverage supporting the requirements of the procedure; or (ii) The procedure imposes limitations on the flyability or performance characteristics of the intended aircraft category.
(2) Instrument departure procedures, unless they impose limitations on the flyability or performance characteristics of the intended aircraft category; (3) Amendments to a previously flight validated instrument approach procedure (IAP), if— (i) The design change can be verified during the design process; and (ii) A safety assessment of the proposed amendment has been completed and confirms that no additional operational risks to the safety of the procedure are introduced by the amendment.
(d) Each IFP custodian must establish documented procedures for applying paragraph (c) to justify when flight validation is not required.
§ 172.55 Ground Validation.p.17
(a) Each IFPDSP must establish detailed procedures for conducting the ground validation of an IFP. The aim of ground validation is to detect any errors in criteria application and documentation and assess the flyability of the IFP.
(b) Ground validation must comprise the following elements: (1) Aerodrome assessment - Verification that the infrastructure and facilities at a certified or authorized civil aerodrome are in place and compliant with the applicable requirements of GACAR Part 139, and where relevant, GACAR Part 137, together with supporting services required under GACAR Part 171, Part 173, and Part 175;
(2) Heliport assessment - Verification that the infrastructure and facilities required for the provision of instrument operations at a certified or authorized heliport are in place and compliant with the applicable requirements of GACAR Part 138, together with supporting services required under GACAR Part 171, Part 173, and Part 175;
(3) Navigational aid coverage – Verification that the navigational aid coverage infrastructure required for the IFP as required by GACAR Part 173 and ICAO Doc. 8071 is in place; (4) Obstacle clearance review – A review conducted by an authorized designer who has not involved in the design of the considered IFP which is to be validated for each segment;
(5) Coding review – A review of the coding of PBN procedures conducted by an authorized designer who has not been involved in the design to be validated; and (6) Fly-ability assessment – Verification that the IFP can actually be flown. The use of software tools is preferred, (e.g. PC-based to full flight simulator), in order to evaluate a range of aircraft types in various weights, speed and center of gravity configurations, and in various weather conditions (temperature, wind effects and visibility).
(c) Where a flyability assessment is conducted using a full flight simulator the following elements must be evaluated: (1) All segments of the IFP must be assessed; (2) In the case of departures, all segments of the procedure from the departure end of the runway (DER) to joining the en-route structure or termination point must be assessed; and (3) In the case of IAPs all segments of the procedure from the Arrival/ Initial Fix through to the Missed Approach must be assessed.
(d) Where procedures share the same segment of flight (e.g. initial, intermediate, etc.), the shared segment needs only to be validated once. (e) In the case of PBN procedures, a test navigation database coded in accordance with ARINC 424 standards must be used in the full flight simulator for integration into the flight management system (FMS). The database must be validated to ensure that the coding of the procedure does not compromise the flyability, safety, or operational intent of the instrument flight procedure.
(f) Where an IFP ground validation has been conducted, the ground validation report must be reviewed by the chief designer of the IFPDSP. (g) Where a ground validation cannot fully verify the accuracy and completeness of all obstacle and navigation data considered in the procedure design or the flyability of the IFP, a flight validation must be conducted. The responsibility for determining if flight validation is required lies with the IFPDSP. In determining whether flight validation is required the custodian must consider a number of factors. These include, but are not limited to the following:
