has been established by the FAA to
provide an area clear of obstructions
and incompatible land uses, in order to
enhance the protection of approaching
aircraft, as well as people and property
on the ground. The dimensions of the
RPZ vary according to the visibility
minimums serving the runway and the
type of aircraft operating on the
runway.
The Threshold Siting Surface (TSS) is
an area closely mirroring the RPZ, but
extending out and up from the primary
runway surface. The TSS is primarily
designed to identify obstructions.
Obstructions to the TSS surface need to
be addressed as soon as possible to
ensure the safety of pilots, aircraft and
people and objects on the ground. The
current TSS slope for Runway 17-35 is
20:1. Should the visibility minimum for
Runway 17 be lowered to one-half mile,
then the TSS slope will be 34:1, while
Runway 35 will remain at 20:1.
3-12
The lowest existing visibility minimum
for approach to Runway 17 is threequarters
mile using the ILS. The
lowest existing visibility minimum for
Runway 35 is one mile. Ultimate
planning will consider lowering the
minimums to one-half mile for Runway
17 and three-quarters mile for Runway
35. A detailed explanation of these
visibility minimums is presented later
in this chapter.
It should be noted that the RPZ for ARC
C/D-II aircraft is significantly larger
than the current RPZ for ARC B-II, and
would extend into areas outside the
existing airport property line. Future
plans should consider acquiring any
property not contained inside the
existing or planned RPZs. The
dimensions for the current and planned
runway protection zones are presented
in Table 3F.

AIRFIELD CAPACITY
A demand/capacity analysis measures
the capacity of the airfield facilities (i.e.,
runways and taxiways) in order to
identify and plan for additional
development needs. Mesquite Metro
Airport’s single-runway system can
provide up to 230,000 annual operations
under ideal conditions. Since it is
known that there are times when
weather can close the runway (usually
due to precipitation or wind), a more
