Total questions: 10
Worksheet time: 5mins
Assertion (A): Wind rose diagrams are used to determine the most economical runway length. Reason (R): Wind rose provides long-term wind frequency and intensity data.
Both A and R are true, and R is the correct explanation
Both A and R are true, but R is not the correct explanation
A is false, R is true
A is true, R is false
A runway satisfies the 95% wind coverage requirement but still experiences frequent operational disruptions. The most probable engineering reason is:
Calm periods were excluded from analysis
Crosswind component exceeds limits during peak gusts
Wind rose data was collected for less than 10 years
Runway length was not corrected for elevation
Consider the following statements regarding Basic Runway Length (BRL): 1. BRL assumes zero effective gradient 2. BRL is computed at airport reference temperature 3. BRL assumes aircraft at full gross weight Which are correct?
1 and 3 only
1 and 2 only
2 and 3 only
1, 2 and 3
Regarding calm periods (<6 km/h wind): 1. They contribute to wind coverage 2. They influence runway orientation 3. They represent acceptable operational conditions Correct statements:
1 and 3 only
2 and 3 only
1 only
1, 2 and 3
Which runway layout is capacity-driven rather than wind-driven?
Single runway
Open-V runway
Intersecting runway
Parallel runway
A device indicating real-time wind direction and approximate speed is:
LDI
Airport beacon
Windsock
ALS
Yellow colour is used for apron markings primarily because:
It is internationally standardized
It resists fuel spillage discoloration
It indicates danger zones
It improves night visibility more than white
Regarding Approach Lighting System (ALS): 1. Assists runway alignment 2. Identifies airport location 3. Essential for low-visibility operations Correct:
1 and 3 only
2 and 3 only
1 only
1, 2 and 3
Which colour combination identifies a land aerodrome beacon?
White + Yellow
Green + Yellow
White + Green
Red + White
If an aircraft lands on apron instead of taxiway during ground operations, the most reliable visual cue indicating the mistake is:
White centreline markings
Yellow surface markings
Green centreline lights
Blue edge lights
