The Picacho Peak Stagefield has designated Air Traffic Control Assigned Airspace around
it in a four NM radius from the center of the airfield and consists of all airspace from the
surface of the airfield up to and including 2,500 feet AGL, or 4,175 feet MSL. The
controlled airspace around Picacho Peak Stagefield and designated airspace in the
surrounding region are shown on Figure 3‐19.
Helipad Imaginary Surfaces
Picacho Peak Stagefield’s imaginary surfaces (Figure 3‐20) are similar in size to those at
SBAH, but since there are four landing lanes, the combined imaginary surfaces are wider.
While the imaginary surfaces go outside of the fenced area around the landing lanes, the
majority are contained within the footprint of the installation. The approach‐departure
clearance surface extends roughly 50 feet past the southern boundary and less than ten
feet past the northern boundary.
Helipad Accident Potential Zones
Picacho Peak Stagefield’s CZs and APZs I (Figure 3‐21) are similar in size to those at SBAH,
but since there are four landing lanes, the combined CZs and APZs I are wider. The CZs
are contained entirely within the fenced portion of the site. The majority of the APZs are
outside the fenced portion around the landing lanes but are contained within the
footprint of the installation. They do extend roughly 50 feet past the southern boundary
and less than ten feet past the northern boundary.
