What are the Night and NVG task considerations for the UH-72A?
1. - Wires and other hazards are much more difficult to detect at night and must be accurately marked and plotted on maps.
2. - Use proper scanning techniques to detect traffic and obstacles and to avoid spatial disorientation. The P should make all internal checks (for example, computations and frequency changes).
3. - Visual barriers (areas so dimly viewable that the existence of barriers or obstacles is uncertain) will be treated as physical obstacles.
4. - Altitude and ground speed are difficult to detect, and use of artificial illumination may sometimes be necessary
5. - Surrounding terrain or vegetation may decrease contrast and cause degraded depth perception during approaches.
6. - Determine the need for artificial lighting prior to descending below barriers. Adjust search/landing light for best illumination angle without causing excessive reflection into the cockpit.
7. - Entering IMC with artificial illumination may induce spatial disorientation.
8. - Cockpit controls will be more difficult to locate and identify.
9. - Take special precautions to identify and confirm the correct switches and levers.
62
TD 102
What are the Night Unaided task considerations for the UH-72A?

More detailed flight planning is required when the flight is conducted in reduced visibility, at night, or in the night vision goggle (NVG) environment. NVG navigation with standard maps can be difficult because of map colors, symbology, and colored markers used during map preparation
71
TD 103
Discuss dark adaptation:
Dark adaptation is the process by which the eyes increase their sensitivity to low levels of illuminations. Each person adapts t darkness in varying degrees and at different rates. The lower the starting level of illumination, the less time is required for adaptation. Dark adaptation for optimal night-vision acuity approaches it maximum level in about 30 to 45 minutes under minimal lighting conditions. If the eyes are exposed to a bright light after dark adaptation, their sensitivity is temporarily impaired. The degree of impairment depends on the intensity and duration of the exposure. Exposure to bright sunlight also has a cumulative and adverse effect on dark adaptation. Reflective surfaces—such as sand, snow, water, or man-made structures—intensify this condition. Exposure to intense sunlight for two to five hours decreases visual sensitivity for up to five hours. Red lights do not significantly impair night vision. Illness also adversely affects dark adaptation. High body temperatures consume oxygen at a higher-than-normal rate. This oxygen depletion may induce hypoxia and degrade night vision.
72

76
TD 103
What are the general procedures to conduct a light degradation check for Supplemental Cockpit Lighting (finger lights, lip lights, flashlights, and chemical light sticks)?
- At night in an aircraft located in an area of low ambient light with interior lighting set for NVG operations, and with ANVIS prepared for use.
- Position a reflective material 12 to 18 inches from the eyes.
- Shine the supplemental light onto the material.
- With the unaided eye, look at the resultant reflection cast on the windscreen.
- Observe this same reflection through the ANVIS
- An acceptable supplemental light source will allow NVG aided vision through the reflection. If the reflection, glare, or stray light interferes with the ANVIS aided vision of any crewmember the light source is unacceptable.
77
TD 103
What the fundamentals of a movement to contact?
- Focus all efforts on finding the enemy.
- Gain enemy contact early with the smallest reconnaissance force within the allotted time.

- Destroy, defeat, disrupt, divert, or delay enemy forces within capability or conduct battle handover or bypass in accordance with the commander’s intent.
78
TD 104
Define Nap-of-the-Earth Flight.
NOE flight is conducted at varying airspeeds as close to the earth’s surface as vegetation and obstacles permit. For NVG training, NOE flight is further defined as operating with the skids or wheels up to 25 feet above trees and vegetation in the flight path.
79
TD 104
Define Contour flight.
Contour flight is conducted at low altitudes conforming to the earth’s contours. It is characterized by relatively constant airspeeds and varying altitude as dictated by terrain and obstacles. For NVG training, contour flight is further defined as operating with the skids or wheels between 25 and 80 feet above highest obstacle (AHO).
80
TD 104
Define Low-Level Flight.
Aviators perform low-level flight at constant altitude and airspeed, dictated by threat avoidance. For NVG training, low-level flight is further defined as operating with the skids or wheels between 80 and 200 feet AHO at an airspeed commensurate with operational requirements and aircrew limitations. Aviators should decrease airspeed if weather and/or ambient light restrict visibility.
81
TD 104
During NVG map preparation how will routes be marked on the map?
Routes will be marked on the map with a solid line.
82
TD 104

Physical hazards are divided into two categories; manmade and natural.
84
TD 104
Wire hazards consist of what?
Wire hazards consist of power lines, guy wires, communications wire, fences, missile-guidance wire, and wire barriers erected by the enemy.
85
TD 105
What is the CAUTION associated with wires while wearing NVDs?
CAUTION Wires are nearly impossible to see with NVDs. They are also difficult to see during certain times of the day; for example, when an aviator is flying into a setting sun. Wires and poles can become coated in dust and snow making them even more difficult to identify. During any mission briefing, an aviator must review the presence of wires and identify the location and status of the wire-hazards map.
86
TD 105
What are your monocular cues IAW with TC 3-04.93?
Several monocular cues assist crewmembers with distance estimation and depth perception. These cues are geometric perspective, retinal image size, aerial perspective, and motion parallax and can be remembered by the mnemonic acronym GRAM.
87
TD 105
Explain geometric perspective IAW with TC 3-04.93.
An object appears to have a different shape when it is viewed at varying distances and from different angles. As illustrated in figure 8-15, the types of geometric perspective include linear perspective (A), apparent foreshortening (B), and vertical position in the field (C) and can be remembered by the mnemonic acronym LAV.
88
TD 105
Explain terrestrial association IAW with TC 3-04.93.
Comparison of one object such as an airfield with another object of known size such as a helicopter helps in determining the relative size and apparent distance of the object from the observer. For example, a helicopter observed near an airport is judged to be in the traffic pattern and, therefore, at about the same distance as the airfield.
89
TD 105
What is Iodopsin?
What is Rhodopsin?
Iodopsin is the chemical which is always present within the cone cells. Iodopsin permits the cone cells to respond immediately to visual stimulation, regardless of the level of ambient light. However, rod cells contain an extremely light-sensitive chemical called rhodopsin, more commonly referred to as visual purple. Rhodopsin is not always present in the rods because light bleaches it out and renders the rods inactive to stimulation. So sensitive is the rhodospin that bright-light exposure can bleach out all visual purple within seconds.
90
TD 105
Explain the night blind spot.
The night blind spot should not be confused with the day blind spot. The night blind spot occurs when the fovea becomes inactive in low light conditions and involves an area from 5 to 10 degrees wide in the center of the visual field. An object viewed directly at night might not be seen due to the night blind spot; if the object is detected, it will fade away when stared at longer than 2 seconds. The size of the night blind spot increases as the distance between the eyes and object increases. Therefore, the night blind spot can hide larger objects as the distance between the observer and object increases.
91
TD 106
Discuss the visual illusions
Relative-motion—the falsely perceived self-motion in relation to the motion of another object. This illusion can be encountered during flight in situations such as formation flight, hover taxi, or hovering over water or tall grass.
Confusion with ground lights—occurs when an aviator mistakes ground lights for stars. When no stars are visible because of overcast conditions, unlighted areas of terrain can blend with the dark overcast to create the illusion that the unlighted terrain is part of the sky.
False horizon illusion—occurs when the aviator confuses cloud formations with the horizon or the ground
Height-depth perception illusion—is due to a lack of sufficient visual cues and causes an aircrew member to lose depth perception. Flying over an area devoid of visual references— such as desert, snow, or water—will deprive the aircrew member of his perception of height.
Crater illusion—occurs when aircrew members land at night under NVG conditions, and the IR searchlight is directed too far under the nose of the aircraft. This will cause the illusion of landing with up-slope terrain in all directions. This illusionary depression lulls the pilot into continuing to lower the collective. This can result in the aircraft prematurely impacting the ground, causing damage to both aircraft and crew.
Structural illusions—are caused by the effects of heat waves, rain, snow, sleet, or other visual obscurants.
Size-distance illusion—is the false perception of distance from an object or the ground, created when a crew member misinterprets an unfamiliar object’s size to be the same as an object that he is accustomed to viewing. Examples—different runway sizes, light intensity.
Fascination (fixation) in flying—can be separated into two categories: task saturation and target fixation.
Reversible perspective illusion—at night, an aircraft may appear to be moving away when it is actually approaching. (Red on right, returning)
Altered planes of reference—the pilot has an inaccurate sense of altitude, attitude, or flight-path position in relation to an object so great in size that the object becomes the new plane of reference rather than the correct plane of reference, the horizon.
Autokinesis—primarily occurs at night when ambient visual cues are minimal and a small dim light is seen against a dark background. After 6 to 12 seconds of visually fixating on the light, on perceives movement at up to 20 degrees in any particular direction or in several directions in succession, although there is no actual displacement of the object.
Flicker vertigo—is not technically an illusion; however viewing a flickering light can be both distracting and annoying. Flicker vertigo may be caused by helicopter rotor blades or airplane propellers interrupting direct sunlight at a rate of 4 to 20 cycles per second. Flashing anticollision strobe lights, especially while the aircraft is in the clouds, can also produce this effect.
92
TD 106
Visibility restrictions (caused by fog, rain, dust, haze, or smoke) reduce the effects of hemispherical illumination. What conditions indicate a reduction to visibility?
- Loss of celestial lights
- Loss of ground lights
- Reduced ambient light levels
- Reduced visual acuity
- Scintillation (the sparkling effect in NVDs)
93
TD 106
The factors increasing stress when performing terrain flight operations while wearing NVDs include ____________, _____________, _______________, and ____________.
- Increased workloads (physical dexterity and mental processes).
- Limited FOV when using NVDs.
- Reduced visual acuity, viewing distances, and depth perception.
- More complex aircrew coordination.
94
TD 106
What are the N/NVG considerations for a VMC approach?
Altitude, apparent ground speed, and rate of closure are difficult to estimate at night. The rate of descent during the final 100 feet should be slightly less than during the day to avoid abrupt attitude changes at low altitudes. After establishing the descent during unaided flights, airspeed may be reduced to approximately 50 knots until apparent ground speed and rate of closure appear to be increasing. Progressively decrease the rate of descent and forward speed until termination of maneuver.
95
TD 106
What are the N/NVG considerations for slope operations?
When conducting slope operations, determine the need for artificial illumination before starting the maneuver. Select reference points to determine slope angles. (References probably will be limited and difficult to ascertain.) If, at any time, successful completion of the landing is doubtful, abort the maneuver. When performing operations during unaided night flight, ensure that the searchlight or landing light (white light) is in the desired position. Using the white light will impair night vision for several minutes. Therefore, exercise added
caution if resuming flight before reaching fully dark adaptation.
96
TD 106

To be considered NVG current, a crewmember must take part every 60 consecutive days in at least a 1-hour flight in the aircraft, while wearing NVG. A RCM must be at a crew station with access to the flight controls.
98
TD 107
During N/NVG operations, when will the anti-collision lights be on? (SOP Pg. 6- 13-2) When will the position lights be on? When will the NVG position Lights be on?
The anti-collision lights shall be on at all times while the engines are operating IAW AR 95-1. All aircraft shall have the anti-collision lights on while the blades are turning, unless otherwise stated by this SOP. (SOP Pg. 6-7-2) The anti-collision light is optional during NVG terrain flight operations below 25’ AHO on established NOE routes or in an RT. (SOP Pg. 6-13-1) The position lights if possible will be on bright anytime the main rotor blade is untied after official sunset unless otherwise stated in this SOP. (SOP Pg. 6-7-2) (SOP Pg. 6-13-2) Position lights may be dimmed during ground operations only at RTs and Stage fields to aid other traffic. (SOP Pg. 6-13-2) The NVG position lights will be ON during all night/NVG Operations. (SOP Pg 6-13-2).

When will the landing/searchlight be used during D/N/NVG operations?
The landing light shall be ON as deemed appropriate by the IP/PC for, all ground operations at base fields, stage fields, and airports, and for corridors to include corridor transitions. The use of the landing light is to provide maximum visibility to ATC and other aircraft. The IP will determine the need for the landing/searchlight prior to performing hovering unaided auto-rotations. (SOP Pg. 6-13-2, 3) RT Operations—unaided aircrews will use the unfiltered landing/search light during approaches to an unlit inverted Y. (SOP Pg. 6-13-4)

What is Hyperopia?
Hyperopia is also caused by an error in refraction—the lens of the eye does not focus an image directly on the retina. In a hyperopic state, when an aircrew member views a near image, the actual focal point of the eye is behind the retinal plane (wall), causing blurred vision. Objects that are nearby are not seen clearly; only more distant objects are in focus. This problem is referred to a farsightedness.

What is astigmatism?
An unequal curvature of the cornea or lens of the eye causes this condition. A ray of light is spread over a diffuse area in one meridian. In normal vision, a ray of light is sharply focused on the retina. Astigmatism is the inability to focus different meridians simultaneously. If, for example, astigmatic individuals focus on power poles (vertical), the wires (horizontal) will be out of focus for most of them.

What is presbyopia?
This condition is part of the normal aging process, which causes the lens to harden. Beginning in their early teens, the human eye gradually loses the ability to accommodate for and focus on nearby objects. When people are about 40 years old, their eyes are unable
to focus at normal reading distances without reading glasses. Reduced illumination interferes with focus depth and accommodation ability. Hardening of the lens may also result in clouding of the lens (cataract formation).

When will a flashlight be used on the flight line?
During hours of darkness, all personnel will hand carry a lighted flashlight when walking on all ramps to ensure they are visible to equipment operators. (SOP Pg. 6-13-1 a. (5)) During night operations a clear lens flashlight is required for use by the fireguard. (SOP Pg. 6-17-2 b. (2)
