EXAM// Terrain Flight Flashcards
When considering the use of a building depicted on the map as an aerial checkpoint, in the past a church has been a good choice due to it’s unique construction and ease of identification. Identification has become more difficult for some newly built churches as their construction has become less distinguishable. When considering the use of a church as an aerial checkpoint one that is co-located with a ___________ is a better choice as it will likely be a more traditional looking church making positive identification more likely.
graveyard
Regarding the Aviation Mission Planning System (AMPS), which of the following is NOT a feature of the system?
En-route Map Updates
Fundamentals of Flight (TC 3-04.4) recommends that when flying at altitudes below 200’ AGL you should use _____ when measuring distance?
KM’s
What is the best type of map to use for analyzing terrain and vegetation?
Topographic
Nap of the Earth
characterized by varying airspeed and as close to the earth’s surface as possible. (For NVG training, altitude is further defined as wheels or skids 0-25 ft. above terrain or vegetation).
Contour
characterized by relatively constant airspeed and varying altitude. (For NVG training, altitude is further defined as wheels or skids 25-80 ft. above highest obstacle).
Low Level
characterized by relatively constant airspeed and altitude. (For NVG training, altitude is further defined as wheels or skids between 80-200 ft. above highest obstacle).
Regarding the Limitations to Terrain Flight, which of the following is not included?
Insufficient mission planning time.
When applying the Time/Distance barrier it is necessary to know that for every 30 knots of airspeed the aircraft will travel _______ per minute of flight.
One Kilometer
Which is the preferred map to use when conducting en-route planning on most long range terrain flight missions?
1:250,000 JOG
When evaluating a pond or lake for potential use as an aerial checkpoint the most important characteristic from the standpoint of visual significance is?
The area size of the feature.
When evaluating a pond or lake for potential use as an aerial checkpoint the most important characteristic from the standpoint of visual significance is?
The area size of the feature.
“In a non-tactical environment, what is the safest way to negotiate a wire crossing?”
At or near the pole or superstructure
Why might railroad tracks or other linear features be difficult to SEE?
Vertical development of vegetation
Which of the following would be considered In-Flight contingency that may be encountered?
System malfunction
What are the four types of barriers used for terrain flight navigation?
Linear, Funnel, Point, Time/Distance
What is the primary determining factor in selection of the mode of terrain flight?
Enemy
A good general rule of thumb to use is: “All roads have ____ ”.
wires
Fundamentals of Flight (TC 3-04.4 Chapter 5) recommends you post all hazards not less than __ __ on either side of the course line for safety during intentional or unintentional deviation. (Answer MUST include distance measurement ie. NM, KM, SM)
10 NM
“When flying ““Nap of the Earth””, which navigation technique would NOT be appropriate based on the Factor of Geographic Orientation ““Timing and Sequence””?”
Dead Reckoning
What are the Masking/Unmasking techniques?
All of the answers given are correct for this question.
(In-Flight, Vertical, Lateral)
A stream that contains water less than 6 months of the year and has a width less than 25 meters is depicted by:
Single Broken Blue line.
How many Masking/Unmasking techniques are there?
3
