Flight Fundamentals (3-04.203) Flashcards
Three requirements for dynamic rollover (1-200)
Pivot point
Rolling motion
Exceeding critical angle
First step of dynamic rollover is (1-201)
Pivoting around a ground contact point (wheel)
As the rate of the rolling motion increases, the critical angle is (1-202)
Reduced
Rollover can occur on takeoff if (1-206)
A wheel or skid is stuck
The ability to interpret terrain during night flight is determined by (4-22)
Flight method
Aided or unaided flight (NVG)
Ambient light
Aircrew ability to employ proper technique
The ability to detect objects at night depends on (4-23)
Object size, shape, contrast
Effective use of night scanning techniques
Contrast of an object depends on (4-26)
Ambient light
Texture of the object
Background Illumination of the object
What factors affect your ability to interpret terrain? (4-28)
Ambient light Viewing distance Flight altitude Moon angle Weather Terrain Season Type of NVG
How does ambient light affect terrain interpretation? (4-30)
Degree of contrast between objects
How does viewing distance affect terrain interpretation? (4-31)
Perceived size of the object and ease of recognition
How does flight altitude affect terrain interpretation? (4- 32-34)
High altitude - greater field of vision, reduced object size, reduced contrast
Low altitude - increased object size, increased contrast, reduced field of vision, ability to silhouette objects on skyline
How does moon angle affect terrain interpretation? (4- 35-36)
High angle - greater illumination, reduced shadows
Low angle - lower illumination, increased shadows, ability to silhouette objects on skyline
How does weather affect terrain interpretation? (4-38)
Inclement weather (snow, rain, fog) reduces visual distance, reduces ambient light, and reduces visual acuity
How does terrain type affect terrain interpretation? (4- 39-44)
Determines quantity of reflected light from the surface.
How does season affect terrain interpretation? (4- 45-51)
Summer - reduced recognition of objects by contrast, increased cover due to foliage
Winter - improved contrast and recognition of terrain features (reduced foliage), often more cloudy (reduced ambient light), heavy snow may offer concealment of terrain/man-made objects
Some of the best navigational cues are (4-58)
Man-made features
The types of man-made features that can be used for navigation include (4-58)
Roads, intersections, bridges, railroads, buildings, and cemeteries
The AN/AVS6 has how large a field of view? (4-68)
40 deg
The AN/AVS6 amplifies ambient light by what factor? (4-68)
2000-3000x
The AN/AVS6 low battery warning is located where? (4-68)
On the visor mount
Due to the location of the low battery warning light, it is most easily seen by whom? (4-68)
Another crew member
The amount of counterweight that can be used with the NVG is (4-69)
12-22 ounces
NVGs do not __ an image, they __ (4-71)
magnify, enhance illumination
How do NVGs distort an image? (4- 75-76)
Depth perception
Distance estimation
Color discrimination
What is the proper method for scanning with NVGs? (4-78)
Rotate eyes and head slowly and continuously
What factors increase risk of spatial disorientation when wearing NVGs? (4-81)
Rapid bank angles or attitude changes
What color lighting is meant to be used with the AN/AVS6? (4-86)
Blue/green
What color lighting is not meant to be used with the AN/AVS6? (4-86)
Red (not authorized)
What are the most common ground landing aids, and when should you expect to see them? (4-150)
inverted Y - US forcesT - NATO forces
The inverted Y is best used for landing when (4-151)
Terrain flight landings
The T is best used for landings when (4-152)
Approaches from >500’ AGL
The desired touchdown point with the inverted Y is (4-151)
Inside the Y aligned with the stem
How do emergency procedures differ between day and night? (4-158)
No difference, except may take longer to respond at night
When conducting low-level flight NVG training, flight is conducted at what altitude? (5-10)
Between 80-200’ above highest object with relatively constant airspeed and altitude
When conducting NOE flight NVG training, flight is conducted at what altitude? (5-11)
At least 25’ above highest object with varying airspeed
When conducting contour flight NVG training, flight is conducted at what altitude? (5-12)
Between 25-80 feet above highest object with varying airspeed and altitude
Shoring is used for (2-39)
Increasing weight distribution of a load that exceeds floor limitation
The strongest directional force to act on cargo in the event of a crash is most likely (2-49)
Forward
The amount of restraint required to keep cargo from moving in any direction is called __ and expressed in __ (2-49)
Restraint criteria, G’s
Define prepared cargo (2-50)
Cargo carried in containers equipped with tie-down devices, or equipment with attached tie-down points
Define miscellaneous cargo (2-50)
Cargo not in containers, or cargo without tie-down provisions
To calculate tie-down requirements, you must know (2-54)
Weight of cargo
Restraint criteria
Strength of tie-downs used
% Effectiveness
The formula to calculate number of tie-downs required is (2-55)
Weakest Link * % Effectiveness
The Army regulation regarding flight fundamentals is
