first 10 mi (16.1 km) of the approach, 5,000 ft (1524 m) for the next a mi
(12.8 km), and 9,000 ft (2743.2 m) for the remaining two miles to the airspace
cylinder around the target center. See Facility Plate No. 179-10, Sheet 15.
188.8.131.52 Impact Area. The surface impact area has a minimum radius Of 1-1/2
mi and is centered on the target.
184.108.40.206 Single Direction Approach. The requirement for a single-direction
approach to the target is a rectangular area one mile wide by 20 mi (32 km)
long, preferably having its length aligned with the prevailing wind. This
area is necessary to encompass the approach, pullup, and recovery of high
speed jet aircraft using the range. See Facility Plate No. 179-10, Sheet 16,
for flight path profile. The first 10 mi (16.1 km) of this primary approach
lane is to permit speed stabilization of the aircraft before beginning the
actual bombing run. The second 10 mi (16.1 km) of the primary approach is for
recorded practice bombing runs, which necessitate installation of
instrumentation and markers along the flight path.
220.127.116.11 Multi-Direction Approach. A multi-direction approach may be
considered in range planning to avoid the detrimental effect on pilot training
caused by frequent repetition of the single-direction approach. A minimum of
two secondary approaches to the target is desirable, each measuring 1 x 20 mi
(1.6 km x 32.18 km). See Facility Plate No. 179-10, Sheet 17, for flight path
profile for primary and secondary approach. The two approaches shall be from
directions as widely divergent as local conditions permit and shall be
oriented to prevent training aircraft from passing over the control tower or
spotting towers. Flights over the secondary lanes are not recorded except for
the point of bomb impact; however, initial point markers are required at
specified locations on the approach lanes. For one type of bull's-eye
lighting for target requisition, refer to Appendix A, Figure A-12.
Targets. Provide a clear area having a minimum radius of 1,500 ft
(457.2 m), with the aiming point as its center.
18.104.22.168 Aiming-Point Elevation. The aiming point shall have an elevation
sufficient to provide a line of sight to it from an aircraft 50,000 ft
(15 240 m) away, approaching at an altitude of 100 ft (30.4a m) above the
Aiming Point Construction. A typical aiming point in flat, open
country should consist of three walls, each 30 ft high by 60 ft long (9.1 m by
18.3 m), forming an equilateral triangle. See Facility Plate No. 179-10,
Sheet 18, for vertically-developed target. It should be of frame
construction, painted international orange, and oriented so that the primary
run-in line forms the perpendicular bisector of one leg of the triangle.
Initial Points. Initial points of aim shall be either fixed or
mobile, depending on terrain conditions and local requirements, and shall be
elevated above any vegetation or obstruction so es to be clearly visible to
pilots Of approaching aircraft.
