Operating constraints
Friedman Memorial Airport has published operating constraints in seven categories: access, weight restrictions, runway notes, noise procedures, environmental, pavement strength and other notes.
The approach to runway 31 follows the east side of the valley; the departure from runway 13 follows the west side of the valley, with landing lights on. This routing is the operating practice.
When the control tower is closed, announce arrivals on frequency 125.6 at 20, 15, 10, and 5 miles out, and on the short final approach. Personnel and equipment may be working on the runway.
Fuel service after dusk requires prior permission.
Prior permission is required for aircraft with a wingspan greater than 100 feet.
Hang gliders, paragliders, and skydiving activity occur on and in the vicinity of the airport, within the Class D airspace up to 18,000 feet MSL.
The runway is limited to aircraft with a maximum takeoff weight of 95,000 pounds or less. Dual wheel aircraft with a maximum takeoff weight greater than 95,000 pounds require prior permission, coordinated 48 hours in advance with the airport manager.
When the control tower is closed, activate the high-intensity runway lights for runway 13/31 via CTAF. The PAPI for runway 31 operates continuously.
When the control tower is closed, land on runway 31 and takeoff on runway 13; operate in the pattern accordingly. The control tower is located 275 feet east of the runway centerline.
A 17-foot road is located 450 feet from the threshold, 250 feet left; 15-foot pipes are located 500 feet from the threshold, 180 feet right; a 7-foot fence is located 550 feet from the threshold, 180 feet left; a 17-foot road is located 550 feet from the threshold, 190 feet left.
A road creates a 65:1 obstruction slope to the displaced threshold; parked aircraft between 0 and 225 feet left create a 0:1 slope to the displaced threshold.
A voluntary fly-quiet curfew applies from 2300 to 0700 local time. Depart to the south. Arrive from the north. Contact the airport manager for noise abatement procedures.
Mountainous terrain surrounds the airport. Night operations and operations in marginal weather are not recommended. Birds have been reported in the vicinity of the runway.
PCR VALUE: 260/F/C/X/T
Locked brake turns are not authorized.
Surface conditions are unmonitored. Aircraft rescue and firefighting service is unavailable between 2300 and 0700.
Limited parking is available for air carrier aircraft.
APU operations are limited to 30 minutes.
Taxiways B5 and B6 are restricted to aircraft with a wingspan of 79 feet or less, Design Group II only.
General aviation transient aircraft with less than a 40-foot wingspan park on the section 2 apron at the blue tie-down spots. Other transient parking is by direction.
This is a cold temperature airport. Altitude corrections are required at or below minus 13 degrees Celsius.
Transient helicopter operations are by direction. Contact airport operations for parking. Dedicated helicopter parking pads are not available.
For clearance delivery, if unable to contact on the flight service station frequency, contact Salt Lake Center.
All surfaces are available to air carrier aircraft except taxiways B5 and B6.

Frequently asked questions
What is the maximum takeoff weight limit at KSUN?
Friedman Memorial Airport, KSUN, limits its runway to aircraft with a maximum takeoff weight of 95,000 pounds or less. Dual wheel aircraft exceeding that weight need prior permission, coordinated with the airport manager 48 hours in advance. This is a hard operational constraint dispatchers must check before scheduling heavier business jets into Hailey. The single runway, 13/31, is the only paved surface serving the field, so there is no alternate runway to absorb heavier operations. Planning around this weight limit is essential for any aircraft near the threshold.
Are there wingspan restrictions for taxiways at KSUN?
Taxiways B5 and B6 at KSUN are restricted to aircraft with a wingspan of 79 feet or less, limiting them to Design Group II aircraft. Larger aircraft can still use other airport surfaces, since all surfaces except B5 and B6 are available to air carrier aircraft. Separately, any aircraft with a wingspan greater than 100 feet requires prior permission to operate at Friedman Memorial Airport. Dispatchers handling larger business jets or air carrier equipment should confirm taxiway routing and permission status before filing into Hailey.
What terrain and approach considerations apply at Friedman Memorial Airport?
Friedman Memorial Airport sits in mountainous terrain, and night use plus operations in marginal weather are not recommended. The published procedure has aircraft approaching runway 31 along the east side of the valley and departing runway 13 along the west side, with landing lights on. Birds are reported in the vicinity of the runway as an additional hazard. These terrain and valley-following procedures reflect the site's location near Hailey, Idaho, and require pilots to be briefed on the specific approach and departure paths before operating at KSUN.
Is fire and rescue coverage available at all hours at KSUN?
ARFF coverage at Friedman Memorial Airport is unavailable between 2300 and 0700 local time. Surface condition monitoring is also unmonitored, per the airport's operational remarks. The control tower's attendance schedule runs all days, all months, from 0700 to 2300, so ATCT and ARFF gaps align with the same overnight window. When the tower is closed, pilots must self-announce and activate runway lighting via CTAF at KSUN. Dispatchers scheduling overnight or early morning operations should account for this reduced-coverage period at Hailey.
Does KSUN have a voluntary noise abatement procedure?
Friedman Memorial Airport asks pilots to observe a voluntary curfew from 2300 to 0700 local time as part of its fly-quiet program. The recommended flow has aircraft departing to the south and arriving from the north. Pilots seeking specific noise abatement procedures are directed to contact the airport manager. This voluntary program, combined with the ARFF gap during the same overnight hours, means operators planning flights into or out of KSUN outside daytime hours should weigh both noise guidance and reduced emergency coverage.
