reading has been taken, the temperahue gauges must be
reset prior to the next hnnup.
3.1.5 Pneumatic Systems. The pneumatic power
supply systems, which provide for normal operation of
the canopy and for emergency extension of the landing
gear, are ground charged through a common tiller in the
nose wheelwell (Figure 3-3, sheet 3). The auxiliary canopy
open pneumatic bottle is in the turtleback behind the
cockpit (Figure 3-3, sheet 1). Additional pneumatic
servicing points are at both hydraulic systems servicing
panels, brake systems, and arresting hook.
Individual pneumatic servicing points and pressure
gauges are provided for the auxiliary and parking brake
systems.
Noie
Dry nitrogen, specification BB-N-41 lB,
Type 1, Grade A, is preferred for tire inflation
and for charging pneumatic systems
since it will not support combustion.
3.1.6 Backup Oxygen Supply. The backup gaseous
oxygen supply is serviced to a maximum of 2,100
psi from an access in the forward right side of the fuselage.
Servicing pressure can be observed on a gauge in
the pilot’s cockpit.
3.2 GROUND HANDLING
3.2.1 Danger Areas. Engine exhaust and intake
danger areas are shown in Figure 3-4. Noise danger
areas are shown in Figure 3-6. (Figure 3-4 shows temperahned
istribution with afterburnersa t maximum nozzle
opening for idle, military, and maximum power.)
Figure 3-4 shows exhaust jet wake velocity distribution
with afterburner at maximum nozzle opening for idle,
military, and maximum power.
The high temperature and velocity of the
engine exhaust is extremely dangerous.
Stay outside engine exhaust area included
within a 90” cone extending 900 feet behind
the aircraft.
Suction at the air intake is strong enough
to kill or seriously injure personnel by
drawing them into or against the inlet.
All personnel in the immediate area shall
wear ear protection whenever an engine is
operating.
Note
If engines are run up in front of a blast
deflector, exhaustje t wake is deflectedu p
and to the sides resulting in distortion of
the patterns shown.
At maximum afterburner power, nozzles
are nearly fully open; at military power,
the nozzles are nearly fully closed.
3.2.2 Radar Radiation Areas. The following paragraphs
describe the hazards to personnel, hazards of
electromagneticr adiation to ordnance,a nd fuel ignition
hazardsg eneratedd uring ANIAPG-71 radar operation.
p&A&--l
Illumination of RDR ENABLE caution light
on RIO CAUTION ADVISORY panel indicates
possible radar radiation on deck.
3.2.2.1 Hazards to Personnel. Minimum safe
distances for personnel from ground operation radar are
indicated in Figure 3-5, sheets 1 and 2. When the planar
array radar antenna is not radiating, minimum safe distance
from other radiating antennas is 6 feet.
3.2.2.2 HERO Condition. HERO conditions exist
when ordnanceo r weaponsc ontaining electroexplosive
devices are present. Hazard to personnel and equipment
is greater because of the lower power density level at
which EED react to radio frequency radiation. The requirement
to maintain a minimum safe distance from
ground operating radar causes the RF radiation hazard
area to increase in size, thereby overlapping into previously
safe areas for personnel. During HERO conditions,
minimum safe distances (personnel) from ground
operating radar (Figure 3-5, sheets 1 and 2) shall not be
considereds afe.M inimum safed istancesd uring HERO
conditions are shown in Figure 3-5, sheets 3 and 4.
HERO unsafe ordnance conditions include assembly/
disassembly of ordnance systems, tests involving electrical
connections to the ordnance, such as primer resistance
check, continuity checks, bare squibs, primers,
blasting caps, and other EED having exposed wire leads
and unshieldedo rdnances ubassembliess uch as rocket
motors, warheads, and exercise heads.
