Question

Obstacles within _________ SM of the DER which require a climb gradient greater than 200 ft per nm are published under "TAKEOFF OBSTACLES NOTES."

a) 5
b) 10
c) 15
d) 20

Answer 1

Obstacles within 5 SM of the DER which require a climb gradient greater than 200 ft per nm are published under "TAKEOFF OBSTACLES NOTES." (option A).

Step-by-step explanation:

In aviation, an obstacle within a certain distance of the DER (departure end of the runway) may require a climb gradient greater than 200 ft per nm (nautical mile). These obstacles are published under 'TAKEOFF OBSTACLES NOTES'.

It means that if there is an obstacle within 5 nautical miles of the departure end of the runway that requires a climb gradient greater than 200 ft per nm, it will be published under the 'TAKEOFF OBSTACLES NOTES'.

Any obstacle within 5 statute miles (SM) of the Departure End of Runway (DER) that requires an aircraft to climb at a gradient steeper than 200 feet per nautical mile will be listed under the "TAKEOFF OBSTACLES NOTES" in the airport's departure procedures, ensuring that pilots are aware of potential obstructions during takeoff.

Thus, the correct answer to this question is a) 5.
