What KHLN publishes

Airport diagram

The FAA airport diagram for Helena Regional — runways, taxiways, ramps and hold short lines. Shown in the browser above; the FAA PDF ↗ is the authoritative copy.

Instrument approaches at KHLN

Helena Regional has 10 published instrument approaches of 4 types (ILS, RNAV (RNP), RNAV (GPS) and VOR). 7 of them offer vertical guidance; ILS gives the lowest minimums. 3 are circling only — bringing you to the airport rather than a runway, to circle for whichever runway the wind favors at circling minimums.

No published approach to runway 05, 23, 17, 35, 10 and 28: landing on those ends in instrument conditions means a circling approach or a visual after breaking out.

Departures and arrivals

Helena Regional publishes 3 departure procedures (SIDs) — charted routes from the runway to the en route structure, assigned by ATC in the clearance. Each one is in the list at the foot of this page with its continuation pages.

Takeoff, alternate and surface information

• Takeoff minimums are published for KHLN. Standard is 1 statute mile visibility for one and two engine aircraft (½ mile for more than two) unless this section says otherwise; Part 91 operators are not bound by them but the obstacle notes apply to everyone.
• Helena Regional has an obstacle departure procedure (ODP): the charted way to clear terrain and obstacles after takeoff in instrument conditions. ATC does not assign it; under Part 91 it is recommended rather than required, and it is what you fly when no SID or radar vectors have been given.
• Non standard alternate minimums are published: if you file KHLN as an IFR alternate, the required forecast is higher than the default 600-2 for precision or 800-2 for non precision approaches. Check the alternate rule tool.
