Define Spatial Disorientation

A pilots erroneous perception of position, attitude, or motion in relation to the gravitational vertical and the Earth’s surface.

What are the different types of Spatial Disorientation?

Type I: Unrecongnized

Type II: Recongnized

Which type of spatial disorientation is the most dangerous?

Type I Unrecognized

What is the most important sensory system for maintaining orientation in flight and what percentage is it estimated to provide?

Visual system and 70-80%

Semicircular canals sense changes in _______ acceleration and react to any changes in _____, _________, and ______ attitude.

angular

roll

pitch

yaw

In the event of suspected or recognized SD, reference ___________ with a good ___________ and attempt to ignore conflicting sensory inputs. In two-pilot aircraft, announce SD and _________ the controls.

instruments

cross check

transfer

What visual illusion would be associated with the difference in size between RWY 36 at CAIRNS AAF and a lane at a stagefield?

Size Constancy

The STANDARDS for respond to IIMC:

1

2

3

4

5

6

7

8

9

Note:

1. Fly the aircraft: The most important single consideration is aircraft control

2. Alert: P* will announce “IIMC” and immediately make the transition to instrument flight

3. Attitude: Level the pitch and bank attitude while maintaining aircraft in trim

4. Torque: Adjust torque as required

5. Altitude: Adjust to desired altitude after establishing initial aircraft control

6. Heading: Establish and maintain heading, turn only to avoid known obstacles

7. Airspeed: Adjust airspeed as necessary

8. Fly the aircraft: Maintain aircraft control and then use aircraft automation to assist in stabilization as appropriate

9. Contact ATC as appropriate, and comply with ATC instructions, local regulations, and SOPs

Note: The best course of action is to anticipate and avoid IIMC. Understand enroute decision triggers. Before going IIMC turn around, if in a permissive environment land or commit to IFR.

Single Engine Emergency Shutdown

NOTE The VAR NR system will revert to the _______ mode automatically

NOTE Before performing an in-flight single engine emeregency shutdown, __________ if the situation will allow for OEI flight

NOTE Make ___________ that:

• The controls of the affected engine are selected, and

• The collective lever is adjusted to maintain the normal engine within the OEI limits

Procedure

certain

1. Twist grip (affected engine) - Rotate slowly to IDLE, check indications, then to off

2. Rotor speed - Trim to maximum
