Definition
Section 97.35 of Title 14 of the Code of Federal Regulations (14 CFR Part 97), which prescribes the rules for developing and publishing Standard Instrument Approach Procedures (SIAPs) that use Radar as the primary means of navigation guidance, including Airport Surveillance Radar (ASR) and Precision Approach Radar (PAR) approaches.
Plain English
It is the specific FAA rule that covers radar approaches — the kind where a controller talks the pilot down using radar instead of the pilot following an onboard instrument approach.
Context Anchor
Seen in FAA instrument procedure material when a procedure or chart reference is tied to the legal rule that authorizes helicopter instrument approaches.
Derivation
The symbol § is the standard legal mark for 'section,' from the Latin signum sectionis. '§97.35' simply means 'Section 97.35' inside Title 14 of the Code of Federal Regulations, which contains the rules for civil aviation.
Why Pilots Care
When a pilot sees an approach plate referenced under §97.35, it tells them the procedure is a radar approach — flown using ATC radar vectors and instructions rather than self-contained navigation aids on the aircraft.
Intuition Check
Do not read §97.35 as a frequency, altitude, or chart minimum. It is a rule citation: “section 97.35.”
Example Sentence 1
The chart legend referenced §97.35, indicating the procedure was a radar approach rather than a conventional instrument approach.
Example Sentence 2
Before flying the procedure the pilot verified that §97.35 still applied after a recent runway change.
