TD 35

Question 1

Define Spatial Disorientation

Answer 1

SD is a pilot’s erroneous perception of position, attitude, or motion in relation to the gravitationalvertical and the Earth’s surface.

Question 2

What are the types of Spatial Disorientation?

Answer 2

1. Type I - Unrecognized
2. Type II - Recognized
3. Type 3 - Incapacitating

Question 3

What type of SD is the most dangerous? Why?

Answer 3

Type I - Unrecognized

an aviator does not perceive any indication of SD or necessarily think anything is wrong. What the aviator sees and feels—or thinks he or she sees and feels— may be corroborated by other senses. The aircraft might be performing normally with no indication of inconsistent or conflicting aircraft control parameters. Unaware of a problem, the pilot fails to recognize and counteract the SD, a mistake that often results in a fatal aircraft mishap.

Question 4

Of the three sensory systems, the_______ is the most important in maintaining the ability to orient and move in three-dimensional space

Answer 4

Visual System

Question 5

The semicircular canals respond to ____acceleration (changes in angular velocity) and react to changes in ___, ____, or ____ attitude.

Answer 5

angular, roll, pitch, yaw

Question 6

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.

Answer 6

instruments, cross check, transfer

Question 7

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

Answer 7

Aerial Perspective

Question 8

Announce “____”, maintain proper aircraft control, ____ make the transition to instrument flight, and initiate immediate ____.

2. Initiate correct inadvertent IMC recovery procedures.
   a.
   b.
   c.
   d.
   e.
   f.
3. Contact ____, as required. Comply with ATC instructions, local regulations, and ___.

Answer 8

Announce “IMC”, maintain proper aircraft control, immediately make the transition to instrument flight, and initiate immediate climb.

2. Initiate correct inadvertent IMC recovery procedures.
   a. Attitude—level the wings and pitch attitude.
   b. Heading—maintain heading; turn only to avoid known obstacles or as briefed for multi-ship operations.
   c. Torque—adjust torque to cruise or climb power settings.
   d. Trim—maintain aircraft in trim.
   e. Airspeed—adjust airspeed as necessary.
   f. Altitude-adjust to desired altitude after establishing aircraft control.
3. Contact ATC, as required. Comply with ATC instructions, local regulations, and SOP.

Question 9

Single Engine Emergency
The Var NR system will revert to the ____ mode automatically.

Before performing an in-flight single engine emergency shutdown, ____ if the situation will allow for OEI flight

Make _____ that:
The controls of the effected engine are selected, and the collective lever is adjusted to maintain the normal engine within the OEI limits

Single Engine Emergency Shutdown Procedure
1. Twist grip (affected engine) -

2. Rotor speed -
   Bleed air heating (if installed) will be shutdown automatically, however, depending on power margin of remaining engine, may be re-engaged as follows:
3. BLD HTG EMER/NORM SW - EMER
4. BLD HTG Rheostat - ON

Answer 9

manual, determine, certain

1. Twist grip (affected engine) - rotate slowly to idle, check indications, then to OFF
2. Rotor speed - trim to maximum
   Bleed air heating (if installed) will be shutdown automatically, however, depending on power margin of remaining engine, may be re-engaged as follows:
3. BLD HTG EMER/NORM SW - EMER
4. BLD HTG Rheostat - ON
