Chapter 6.5 - Exam Review Flashcards
List the three basic stages of Collision Avoidance?
- Detection.
- Decision.
- Evasive Action.
If two Aircraft are on a converging Collision Course, the target Aircraft will appear to (remain stationary in/track across) your Aircraft’s windscreen?
Remain Stationary In.
Outside a visual cone with an apex angle of 10°, the maximum range at which a target can be sighted will be reduced to about (one half/one tenth) of the maximum central vision range?
One Tenth.
True or False. For two Aircraft to collide, they must be at the same Altitude or they must have a constant elevation angle to each other?
True.
Is it possible for the converging paths to meet when the relative bearing between two Aircraft is not constant? (Yes/No) Why?
- Yes.
- If the Speed, Heading, or Rate of Climb/Descent are changing.
In Collision Avoidance, the total time of 12.5 seconds must be considered as the (minimum/maximum) average delay from sighting to evasive action?
Minimum.
If the vision from one eye is obstructed by a windscreen post for instance, opposing traffic may not be seen in the (peripheral vision/blind spot) of the other eye?
Blind Spot.
Where do most mid-air collisions occur?
Below 3,000 feet AGL within 10 NM of non-towered Aerodromes.
In normal flight, an area of at least (20°/60°) to the left and right of your flight path and at least (20°/60°) above and below your flight path should be scanned?
- 60°.
- 20°.
If another Aircraft does not move horizontally or vertically on your windscreen but is increasing in size, what should you do?
Take evasive action immediately.
When visually scanning, the time taken for a saccade/rest cycle is (1 second/0.33 second)?
0.33 second.
When visual scanning, why would you normally pause and refocus for a second or two at the end of each scan?
To allow your peripheral vision to pick up any movement.
List the three main factors (other than meteorological) that are involved in mid-air collisions?
- High Traffic Density Areas.
- Lack of Concentration.
- Restriction Vision.
True or False. When scanning for other Aircraft, one limitation of the eye is its inability to discriminate very small objects?
True.
When scanning for other Aircraft, what is the best way to reduce the effects of glare?
Sunglasses.
True or False. Radio-alerted see and avoid is more effective than basic see and avoid because they have to give way to your Aircraft?
True.
True or False. It is not necessary to check for Aircraft overtaking from behind because they have to give way to your Aircraft?
False.
Haze, Drizzle and Glare (do/do not) affect the ability of our eyes to see other Aircraft?
Do.
