the hair that sticks into the fluid and interpret the 3 dimensional motion
What connects your sinuses to your inner ears? - ANS-the Eustachian tube
What is the acronym "ICEFLAG"? - ANS-Inversion Illusion, Coriolis Illusion, Elevator
Illusion, False Horizons, Leans, Autokinesis, Graveyard Spiral
What causes the leans? - ANS-Whenever you are flying and you are abruptly roll the
wings level and your body still feels like you are turning
The acceleration force from the power increase is what puts you back into your seat and
may cause you to experience what illusion? - ANS-Somatogravic Illusion
What is a Graveyard Spiral? - ANS-The pilot will start to turn the airplane and then the
body will get used to being in a prolonged turn and then when you roll wings level, you
mistake the feeling of the leans and try to turn back into a turn but don't realize it and
this causes you to pull back and tighten the turn since you are loosing altitude. Causing
you spiral out of control.
What is the Coriolis Illusion? - ANS-Usually in a steep turn and when you look away you
feel like you are on a different plane. Think about spinning around a baseball bat and
then try to run. The fluid in the inner ear normalizes and then when you move your head
you feel as though you are acting on a different plane and this causes you to think the
aircraft is banking or performing a maneuver when it really isn't.
Posture requires brain power and better posture keeps you? - ANS-Focused. It keeps
your airway wide open when you look up.
Why is posture important when flying? - ANS-It helps you align your body, which can
help you fly feel what the aircraft is doing and know what it is doing. When conditions
allow (VMC/VFR) you use posture sensations (somatosensory sensations), vestibular
sense, and visual senses you can fly the aircraft quite adequately with these senses.
What can happen when you do not have good posture? - ANS-You may suffer from
disorientation in uncoordinated turns and the acceleration forces of the aircraft. Don't
, however, fly from the "seat of your pants" you are putting yourself at risk of suffering
from disorientation.
What is the elevator illusion? - ANS-It is caused by updrafts and downdrafts that are
confused by the pilot to mean that the airplane in either a nose up or nose down attitude
when it is not.
What is the inversion illusion? - ANS-It is when a pilot stops a climb abruptly and this
creates the feeling as though the pilot is tumbling backwards inflight when he is not in
reality.

it appears to be moving. However, it is not moving.
What are all the vestibular illusions? - ANS-Inversion Illusion, Coriolis Illusion, Elevator
Illusion, Leans, Graveyard Spiral, Somatografic Illusion
What are the visual illusions? - ANS-False Horizon, Autokinesis, Runway/Terrain Slope,
Runway Width, Black Hole Illusion, Empty-Field Myopia
What is empty field myopia? - ANS-You eyes will not focus on one thing when looking to
the blue sky and this may make it hard to see traffic
What are the three different instrument cross-check techniques? - ANS-Selected Radial
Cross-Check, Inverted V Cross-Check, Rectangular Cross-Check

scanning from the attitude indicator to then to another instrument, then back to the
attitude indicator and repeating this process multiple times.
What is attitude instrument flying with the control and performance method? - ANS-You
use a specific power setting and pitch setting to receive a determined performance from
the aircraft.
What are the performance instruments? - ANS-Airspeed, Altimeter, Vertical Speed
Indicator
What are your control instruments? - ANS-attitude indicator, manifold pressure,
tachometers, fuel flow, etc.
