Definition
An FAA design and criteria document that establishes the obstacle clearance, performance, and procedural standards used to build instrument flight procedures for helicopters that rely on area navigation systems such as GPS. It governs how helicopter RNAV approaches, departures, and routes are constructed, including required protected airspace, descent gradients, and minimums tailored to helicopter performance.
Plain English
It is the FAA rulebook used to design GPS-based instrument procedures specifically for helicopters. It tells procedure designers how much clearance from obstacles is needed, how steep descents can be, and what minimums can be published, all based on how helicopters actually fly.
Context Anchor
Seen in helicopter instrument procedure discussions, especially when explaining how IFR helicopter routes and approaches to heliports are designed and protected.
Derivation
Area Navigation (RNAV) means a method of flying that lets the aircraft go directly between any two points rather than following ground-based navigation aids. The full title signals that this standard is the helicopter-specific version of RNAV procedure design criteria used in the United States.
Why Pilots Care
It ensures helicopter RNAV procedures are built to consistent safety standards that account for rotorcraft performance and landing capabilities.
Intuition Check
Do not read “standard” here as a general suggestion or best practice. In this context, it means an FAA design standard used to create published helicopter RNAV instrument procedures.
Example Sentence 1
The new IFR heliport approach was developed under the United States Standard for Helicopter Area Navigation (RNAV), which allowed for steeper descent angles than a fixed-wing procedure would permit.
Example Sentence 2
Pilots must verify that any helicopter RNAV procedure they brief meets the United States Standard for Helicopter Area Navigation (RNAV) before accepting an IFR clearance.
