Upgrading to ARC C/D-II presents
deficiencies on both the north and
southeast ends of the runways. On the
southeast end, the OFA extends beyond
the existing property line into a portion
of the Devil’s Bowl Speedway. On the
north end, only 650 feet of OFA is on
airport property.
Obstacle Free Zones (OFZ)
Runways served by an instrument
approach, as are both ends of Runway
17-35, must consider the FAA’s criteria
for the OFZ. The OFZ is an imaginary
surface which precludes object
penetrations, including taxiing and
parked aircraft. The only allowance for
OFZ obstructions is visual navigational
aids mounted on frangible bases which
are fixed in their location by function.
3-11
The FAA’s criterion for runways utilized
by large aircraft and served by an
instrument approach requires a clear
OFZ to extend 200 feet beyond the
runway ends, by 400 feet wide (200 feet
on either side of the runway centerline).
The OFZ is established to ensure the
safety of aircraft operations. If the OFZ
is obstructed, the airport’s approaches
could be removed or approach
minimums could be increased.
Currently, there are no OFZ
obstructions at Mesquite Metro Airport.
Future planning should maintain the
OFZ. Table 3E presents the existing
C/D-II safety area design standards, as
well as the deficiencies to those
standards.

Runway Protection Zones (RPZ)
Another consideration is the FAA
recommendation for compatible land
uses. The runway protection zone
(RPZ) is a trapezoidal area centered on
the runway and typically beginning 200
feet beyond the runway end. The RPZ
