Source: Docket 1580, 28 FR 6719, June 29, 1963, unless otherwise noted. Subpart A—General § 97.1 Applicability. (a) This part prescribes standard instrument approach procedures to civil airports in the United States and the weather minimums that apply to landings under IFR at those airports. (b) This part also prescribes obstacle departure procedures (ODPs) for certain civil airports in the United States and the weather minimums that apply to takeoffs under IFR at civil airports in the United States. (c) Additional applicability of copter procedures for powered-lift is set forth in part 194 of this chapter.

As used in the standard instrument procedures prescribed in this part— Aircraft approach category so so (1) Category A: Speed less than 91 knots. (2) Category B: Speed 91 knots or more but less than 121 knots. (3) Category C: Speed 121 knots or more but less than 141 knots. (4) Category D: Speed 141 knots or more but less than 166 knots. (5) Category E: Speed 166 knots or more. Approach procedure segments (1) Initial approach is the segment between the initial approach fix and the intermediate fix or the point where the aircraft is established on the intermediate course or final approach course. (2) Initial approach altitude is the altitude (or altitudes, in high altitude procedure) prescribed for the initial approach segment of an instrument approach. (3) Intermediate approach is the segment between the intermediate fix or point and the final approach fix. (4) Final approach is the segment between the final approach fix or point and the runway, airport, or missed approach point. (5) Missed approach is the segment between the missed approach point, or point of arrival at decision altitude or decision height (DA/DH), and the missed approach fix at the prescribed altitude.

Editorial Note: The procedures for §§ 97.21 through 97.37, respectively, are not carried in the Code of Federal Regulations. For Federal Register www.govinfo.gov. § 97.20 General. (a) This subpart prescribes standard instrument approach procedures and takeoff minimums and obstacle departure procedures (ODPs) based on the criteria contained in FAA Order 8260.3, U.S. Standard for Terminal Instrument Procedures (TERPs), and other related Orders in the 8260 series that also address instrument procedure design criteria. (b) Standard instrument approach procedures and associated supporting data adopted by the FAA are documented on FAA Forms 8260-3, 8260-4, 8260-5. Takeoff minimums and obstacle departure procedures (ODPs) are documented on FAA Form 8260-15A. These forms are incorporated by reference. The Director of the Federal Register approved this incorporation by reference pursuant to 5 U.S.C. 552(a) and 1 CFR part 51. The standard instrument approach procedures and takeoff minimums and obstacle departure procedures (ODPs) are available for examination at the U.S. Department of Transportation, Docket Operations, 1200 New Jersey Avenue SE, West Building Ground Floor, Room W12-140, Washington, DC 20590, and at Aeronautical Information Services, 1305 East-West Highway, Silver Spring, MD 20910, or at the National Archives and Records Administration (NARA).
