Pick the correct statements about approach-zone surveying, wind representation, take-off/landing direction, and aircraft rating in airport engineering.

Introduction:This question tests key airport-planning concepts: obstacle limitation surfaces, wind data visualization, operational wind usage for take-off/landing, and the definition of aircraft rating in terms of wing and power loading.

Given Data / Assumptions:

• Standard obstacle limitation surfaces include horizontal, conical, and transitional surfaces.
• Wind data for runway orientation is summarized via wind-rose charts.
• Operational best practice is to take off and land into the wind.
• Aircraft rating relates to wing loading and power loading.

Concept / Approach:

Each statement reflects accepted airport engineering/operations practice. If all standalone statements are correct, the inclusive option is correct.

Step-by-Step Solution:

Verification / Alternative check:

These are standard textbook definitions and practices used for siting/orienting runways and understanding performance metrics.

Why Other Options Are Wrong:

• A, B, C, D individually are correct but incomplete; the most complete choice is E.

Common Pitfalls:

• Overlooking that multiple independent statements can all be true in such questions.
• Confusing wind-rose depiction (frequency by sectors) with mere wind-speed logs.

Final Answer:

All the above.
