Separate a departing helicopter from an arriving helicopter by ensuring that the departure does not takeoff until the arrival has _________.

Question

BlackTom AI · Accepted Answer

The correct answer is landed because separation between a departing and arriving helicopter is achieved once the arriving helicopter has completed its touchdown, removing the immediate conflict between the climb-out path of the departing aircraft and the approach/hover area of the arriving aircraft.

Relevant knowledge points and concepts:
- Aircraft separation prevents conflicts in time and space between flight paths.
- For helicopters, conflict arises during approach, hover, and touchdown phases; once an arrival has landed, it is no longer in the arrival flightpath.
- Visual contact alone does not guarantee safe separation; the aircraft could still be maneuvering into position.
- Requiring the arriving helicopter to taxi off the landing area is more restrictive than necessary and can cause undue delays.

Step-by-step reasoning:
1. If a departure begins before the arrival has touched down, both aircraft could occupy or cross the same airspace (approach and climb paths), increasing collision risk.
2. When the arriving helicopter has landed, it is on the ground and no longer in the approach/hover space; the departure can then safely commence without conflicting flight paths.
3. Establishing visual contact (option B) only ensures pilots/ATC can see each other; it does not ensure vertical or lateral separation because one could still be on final approach.
4. Requiring the arrival to taxi off the landing area (option A) is conservative and not the standard minimum need for separation; landing alone is sufficient for safe separation and reduces unnecessary delays.

Why the correct answer is correct:
- “Landed” directly removes the airborne conflict by ensuring the arriving helicopter is no longer in the approach/climb envelope, which is the established operational minimum for separating departures from arrivals.

Why the other options are incorrect:
- "Established visual contact with the departing aircraft" is insufficient for separation because the arriving aircraft may still be maneuvering in the shared airspace.
- "Taxied off the landing area" is unnecessary as a minimum requirement; it is more restrictive than required.

Conclusion: The departure must not take off until the arrival has landed — confirming the provided answer: landed.
