starts at the lateral edges of the primary surface and the approach‐departure clearance
surface. It continues outward and upward at the prescribed slope to an elevation of
87.5 feet above the specified helipad. It then rises vertically to an elevation of 150 feet
above the helipad elevation.
Airspace Protection MCA (Figure 21)
The Picacho Peak Stagefield Airspace Protection MCA is composed of the designated Air
Traffic Control Assigned Airspace around the installation, which extends for four nautical
miles around 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. Additionally, the AZARNG
has a desire to work with the Federal Aviation Administration to establish this airspace as
Class D Airspace in the future, which would encompass the same footprint. This airspace
is important for helicopter training activities that occurs around Picacho Peak Stagefield
and should be maintained to separate commercial and private aircraft operators when it
is in use. Further, development within it should be managed to maintain building heights
that will not interfere with aircraft operations.
Primary Helicopter Training Route MCA (Figure 22)
Due to its size, this MCA is not included as part of the Picacho Peak Stagefield MCAOD.
The Primary Helicopter Training Route MCA addresses the general flight corridor
between Silverbell Army Heliport and Picacho Peak Stagefield, as well as an additional
buffer around the general flight route and each installation. This MCA serves two
primary functions. First, it is meant to provide awareness to residents and property
owners about the areas that are commonly used for helicopter operations. Secondly,
through this awareness, it is meant to promote development in the area that is not
impacted by helicopter overflight (such as noise‐sensitive uses), or impactful to
helicopter safety (such as tall structures or uses that generate excessive light and glare).
Additionally, UASs should be regulated in this MCA so that they do not interfere with
military flight operations or the safety of AZARNG personnel. This MCA has two
subzones.
Primary Helicopter Training Route MCA Subzone A
Subzone A is composed of a three‐mile wide general flight corridor between Silverbell
Army Heliport and Picacho Peak Stagefield. It also includes a 1.5‐mile radius around the
center of each installation. Due to the nature of helicopter flight, there is not a specific
flight route that is used between the two installations. A majority of flight activity
between them occurs within this corridor, but operations may also occur outside
depending on training needs or other factors. This Subzone is meant to provide
awareness to property owners and potential property buyers that helicopter overflight
occurs in the area. This can be achieved through strategies such as placement of signage,
real estate disclosures, or requiring a note on plat documents of such activity.
