NP4 Physiology and Water Survival
The purpose of aviation physiology training
is to familiarize all prospective and designated aeronautical personnel,
selected passengers, project specialists, and any other authorized personnel
with the aero medical aspects of flight and prepare them to properly employ
ALSS and survival procedures.
is required for all project specialists and is valid for 48
months in the same category aircraft.

Note: The first time that
you complete this training, you will need to attend class III swim training
and the NP4 training. After that, you will only need to attend the
second day of training (NP4). If you have been previously qualified,
but feel that you may need more practice with the swim strokes, etc.,
please attend both days.
For access to NAS Patuxent
River for medical reasons or to attend swim training, please call the
VXS-1 Project Office at 301-342-8975.
Topics covered in
this training include:
- Aviation Physiology : Classroom presentation and
low-pressure chamber flight (when applicable) on the effects of altitude
on the human body. The principles of cardiovascular and respiratory
physiology are emphasized. Presentation primarily covers hypoxia, hyperventilation,
trapped gas, evolved gas (decompression sickness), and aviation oxygen
- Sensory Physiology : Classroom presentation
and training device evolution (when applicable) that continues discussing
the effects of altitude on the human body. Specifically, the stressors
of flight that affect sensory adaptation (acceleration, darkness, lack
of visual cues, visual illusions, etc.) are covered. Disorientation,
temporal distortion, motion sickness caused by flight, and situational
awareness are also typical topics for discussion. Depending on the aircraft
type (jet, propeller, helicopter, etc.), special protective devices,
such as night vision devices, laser protection, and threats such as
lasers are also discussed
- Emergency Egress/Systems: Classroom presentation
and dynamic training evolutions (where available/appropriate) on emergency
egress/systems. Lecture for tactical jets emphasizes the psychological
aspects of the ejection decision, aeromedical aspects of ejection, windblast,
flailing injuries, seat-man separation, parachute opening, parachute
descent (over land), and landing. Emergency ground egress is also covered.
Lecture for cargo/transport/patrol emphasizes bailout, parachute opening,
descent (over land), and landing, as well as crash survival. Lecture
for helicopters emphasizes crash survival. Note: Ditching for cargo/transport/patrol/helicopters,
etc., covered in NAWSTP.
- Aviation Life Support Systems: Classroom presentation
and drills (where available/appropriate) covering applicable ALSS items/survival/rescue
equipment utilized by specific aircraft/aircrews. Helmets, anti-exposure
systems, flight clothing, survival vests, flotation devices, life rafts,
special weapon systems like laser and CBR protection equipment, signaling
devices, survival avionics, and anti-g suits for tactical aircrews are
typical items discussed.
