AP107 - Situational Awareness
The four systems that help establish SA
Visual System
Vestibular System
Auditory System
Somatosensory System
The three types of spatial disorientation
Unrecognized, recognized, and incapacitating
The characteristics of noise that are of concern to pilots
Frequency and intensity of the noise
Duration of exposure to the noise
distance from the noise sorce
The three types of acceleration and their definitions
Linear acceleration - a change in speed without a change in direction
Radial acceleration - a change in direction without a change in speed
Angular acceleration - a change in both speed and direction
The five types of oxygen storage systems
Low Pressure Gaseous, High Pressure Gaseous, Liquid Oxygen, Solid State, and OBOGS
This processing mechanism type omits 50% of the information processing loop
The subconscious
The two subsystems of the vestibular system and the types of illusions they are prone to
The semicircular canals - somatogyral
otholith organs - somatogravic
The definitions and units of measurement for frequency, intensity, and duration
Frequency - pitch, measured in Hertz
Intensity - loudness, measured in Decibels
Duration - time, measured in seconds/minutes/etc
The three types of G force and their definitions
Transverse G force - the force applied to the front or back of the body (i.e. take off)
Negative G force - force being applied from the feet towards the head
Positive G force - force being applied from the head towards the feetThe two types of oxygen delivery systems and their Operating limits (normal and emergency)
Continuous flow - FL250 & FL300
Pressure Demand - FL430 & FL500
The three levels of awareness
2. Comprehension
3. Prediction
Name the threshold for movement for each of the three axes of the semicircular canals
Z axis (yaw) - 1.5 degrees per sec
Y axis (pitch) - 2.1 degrees per sec
X axis (roll) - 2 degrees per sec
The two types of hearing loss and their definitions
Conductive hearing loss - occurs when one of the parts of the ear that is designed to transmit mechanical energy fails
Sensorineural hearing loss - occurs when the hair cells of the cochlea are damaged, destroyed, or degenerated due to overexposure to loud noise
The five factors that determine the effects of G forces
Magnitude of G Force
Duration of exposure to the G force
Rate of Application (G onset)
Direction of force
Previous G exposure
indentify the T-6's OBOGS regulator and explain its components
The GRU-78, has 3 levers (O2 concentration lever, O2 pressure lever, and O2 supply lever), bit button (to test OBOGS), and an oxygen flow indicator
Name the 5 types of SA and give an example of each
Geographical - knowledge of the location of your aircraft or other landmarks
Spatial/Temporal - knowledge of the aircrafts altitude, attitude, heading, velocity, etc.
System - knowledge of your system's status, radio settings, altimeter settings, etc.
Environmental - knowledge of weather and other natural events
Tactical - knowledge and identification of other aircraft and threats
Name all the somatogyral and somatogravic illusions
Somatogyral - the leans/graveyard spin, The coriolis illusion, the giant hand phenomenon
Somatogravic - Pitch up/pitch down illusions, the g-excess effect
Name 4 things that can be severely affected by vibration
Tracking - vertical tracking is severely impaired with vibration
Reaction time
Visual impairment - can cause blurred vision
Fatigue
Anti-G suit - Air bladders inflate around the thigh, calf, and abdomen areas to offer 1-1.5 gs of protection
AGSM - Lower muscle straining and a cyclic air exchange technique that forces blood into the brain
Explain the components of a PRICE check and how often you should preform them
Pressure
Regulator
Indicator
Connections
Emergency
Perform every 10,000 ft or every 15 minutes
Name the three categories of in-flight tasks based on their importance
1. Terrain-clearance tasks (fly the aircraft)
2. Mission critical tasks - essential for the successful completion of the mission
3. Noncritical tasks - these tasks make no significant contribution to the mission, but can snowball into a higher level task if given enough time
Name the steps required to overcome SD
1. Transition to instruments
2. Believe the instruments
3. Back up the pilot flying on instruments (if applicable
4. Minimize head movements
5. Fly straight & level
6. Be prepared to transfer/assume control
7. Egress
Two ways vibration can be passed to the body
acoustically or by direct mechanical linkage
As blood pressure drops from the application of Gs, the cardiovascular system attempts to compensate by constricting peripheral blood vessels and increasing heart rate
Describe what a plenum is
The plenum functions as a holding tank between the OBOGS unit and the regulators
