Tactical training is conducted below 300 feet AGL, and other flight operations are
typically conducted between 500 feet and 1,200 feet AGL. Although the entire TFTA is
used for training, there are certain training areas within its confines that serve as the
primary training areas. This is due to their proximity to Silverbell Army Heliport that
provides specialized training such as night training. The airspace within the TFTA is not
restricted nor protected airspace exclusive to military use. The purpose of this MCA is to
assert awareness to the public of the expanse of the TFTA used by the AZARNG for
helicopter training.
Helicopter Night Training MCA (Figure 28)
Due to its size, this MCA is not included as part of the Silverbell Army Heliport MCAOD.
The Helicopter Night Training MCA is composed of the general flight corridors used for
specialized night training. The flight corridor is shown as a five‐mile wide corridor and
follows the typical night training routes used by the AZARNG. This MCA addresses areas
that may generate lighting levels that may affect night training missions and operations.
There are two types of light pollution that can impact military operations: point source
lighting and ambient lighting or background lighting. Light intensity decreases with
distance, therefore, the more distance between the light source and the military
installation, the greater the reduction of light pollution impacts. Lighting regulations
should be considered within this MCA that include fully‐shielded and/or full‐cutoff light
fixtures, and prohibit LED billboards.
