Background and Considerations
Careful consideration should be given by the on-scene Incident Commander and/or EMS personnel prior to making the determination to request and initiate the use of the following resources.
Most of the aircraft shown on the source list are not inspected/carded nor approved by a USFS or DOI Cooperator Aircraft Letter of Approval. These non-approved aircraft do not have current procurement agreements with the federal agencies and as such cannot be directly ordered from the vendor.
Contract aircraft that are federally carded and approved for short haul or cooperator aircraft approved by a letter of approval may be used exclusively (on stand-by) for an incident through normal dispatch/helibase ordering procedures.
Process for activation of military aircraft may vary from state to state. There may be delays in response.
Aircraft that have not been inspected/carded or approved by a Cooperator Aircraft Letter of Approval for agency use shall not be placed on stand-by for a federal incident but may be ordered through the emergency “911” system as approved by the appropriate Incident Commander or Line Officer.
An emergency helicopter request should be initiated and coordinated through the local dispatch or Geographical Area Coordination Center (GACC).
For time critical or potential long term assignments request military, National Guard or Coast Guard extraction capable resources through the Air Force Rescue Coordination Center (ARFCC), phone #: 800-851-3051. It is their job to locate the closest asset to fulfill your emergency rescue needs. It is important to note resource availability may be limited due to military deployments or other factors, and response time may be 2-3 hours.
In some circumstances, orders for county/sheriff department owned aircraft can be placed directly or with the specified contact.
Additional Resource Information
A cable winching device permanently mounted to the helicopter that is capable of lowering/raising persons attached to the cable.
To transport one or more persons suspended on a fixed line (150’-250’) beneath a helicopter. The intent is to transport persons a short distance (short-haul), normally from a limited or inaccessible location to a safe landing area.
Updates and Source Verification
The NWCG National Interagency Aviation Committee intends to keep this document continuously updated. However, accuracy of source information can change due to unforeseen circumstances, and many factors may influence availability and response times. Users must verify source information accuracy based on individual needs and circumstances.

EHE Mission Planning
The following information was compiled by the Intermountain Healthcare Life Flight Program, Salt Lake City, Utah, and is intended to assist those involved in mission planning for an emergency extraction.
Their website states, “A hoist rescue is a great tool for extracting patients from challenging environments; however, this type of operation does have some limitations. Good communication between the requesting agency and Life Flight is critical in creating a plan to best serve all agencies and the patient safely.”
For additional information, visit the Intermountain Healthcare Life Flight website
Minor revisions have been incorporated into the information to fit the audience.
Mission planning should begin with these types of questions:
- What is the nature of the intended short-haul/hoist rescue?
- What is the weather at the scene?
- What do you want the rescuer to do?
- What is the plan if the rescuer cannot complete the mission?
- Patient information (i.e. location, mechanism of injury, condition, anyone with the patient, contact)
- Is there a Command Post (location, IC contact, radio frequencies)?
- Is SAR at the scene or deployed?
- Is there a landing area (near the patient, near the Command Post)?
- Where is the nearest location for jet fuel?
- Is there anything else you want us to do before we leave the area?
Factors That Limit Hoist Operations:
- Winds are greater than 20 mph, poor visibility, or severe weather.
- If total weight of patient and equipment exceeds 450 lbs.
- Hoist operations are not conducted at night.
- Over water.
We may not be able to complete a short-haul/hoist missing if:
- There are unresolved communications issues or safety problems.
- Near dusk.
- Patient location requires technical rescue.
- There’s avalanche potential at patient location
Initial Short-Haul/Hoist Risk Assessment:
- Life threatening injury or illness.
- Time dependent injury.
- Ground evacuation may endanger patient and/or other personnel.
- Ground evacuation would be time consuming.
- Ground evacuation is not possible.
- No landing area near the patient.
Terrain: Alpine, forest, slope, snow, etc. When possible, establish a nearby alternate landing area.
Obstacles: Trees, cliffs, rock scree, loose debris, dust, wires, limited daylight, rotor wash, etc.
Method: Net, bag, litter, harnesses, tag line, etc. Logistics, type of insertion/extraction.
Alternatives: Standby and/or assist SAR with a ground rescue, land near victim.
Safety: Team reviews available information and identifies concerns. Determines “Go/No Go” decision and justifies why
