Scene Calls

Mission Statement:

Our mission covers responses to "scene" calls, emergent calls through the 9-1-1 system. This can include motor vehicle crashes, falls, horseback riding incidents,  bicycle crashes, etc.,
and comprises about 38% of our call volume (62% inter-facilities).


How far do we go? 
Though we have ranged as far as 250 miles, we normally consider
150 miles our mission range. For scene calls, 50 miles or less is the norm.



  1. 75" x 75" DAY, 125" x 125" NIGHT
  2. WET DOWN dusty areas prone to "brown out" conditions.
  3. NO overhead OR approach obstructions, approach path 8:1
  4. FLAT LZ w/ MAX 5 degree slope.
  5. 100 ft. from Emergency vehicles, patient, or buildings.
  6. 200 ft. from non-emergency personnel (on-lookers etc.)
  7. 500 ft. from horses and other domestic livestock.
  8. NEVER downwind from HAZMAT AREA
  9. 1000 ft. From HAZMAT AREA.
  10. Cement, asphalt, grass, or hard packed dirt are preferred surfaces.
  11. No loose debris or loosely packed surfaces.
  12. NOTIFY Crew of any patients who are: Combative, in Police Custody or
    Contaminated by any HAZMAT, including gasoline.



    1. WET DOWN dusty areas prone to "brown out" conditions.
    2. INFORM PILOT PRIOR TO ARRIVAL OF ANY NEARBY HAZARDS e.g. trees, power and telephone lines, antennas, traffic, LZ surface.
    3. Though we can land without radio contact with the LZ commander, it's a great help if we can talk to someone on the ground. CALCORD is the frequency of choice for most EMS helos: 156.075 no PL. We can come up thousands of other frequencies as well.    


    1. WET DOWN dusty areas prone to "brown out" conditions.
    2. BE MORE DESCRIPTIVE of the LZ and hazards.
    3. MARK LZ clearly with Strobes in a square pattern, bean bag lights, or vehicle lights crisscrossed at the landing spot.
    4. NEVER point lights towards the aircraft.
    5. Turn off headlights that point at LZ or aircraft after landing.
    6. Radio communications with the ground is a requirement for landing. As with daytime landings, CALCORD works well: 156.075 no PL.


    You may stand with your back to the wind arms raised in the LZ to mark the intended spot of Landing, but EVERYONE must remain well clear of the LZ once the aircraft has began it"s final approach. Ensure that anyone near the landing helicopter has turned away or is wearing protective goggles.   During the ground phase we've included some diagrams describing the danger areas around the BK-117, and what to watch for:


    Before approaching the helicopter that is running, make sure you make eye contact with
    a crewmember, to be brought in, or motioned in, to the helicopter. A good habit to get
    into, is to bend down when passing the aircraft's blade's tip path plane.
