At what DME must you contact departure control during the climbout?

Contacting departure control during climbout at the specified distance from the departure airport is critical for maintaining proper communication and compliance with air traffic control procedures. The correct distance, in this case, is 6 DME.

This requirement ensures that as the aircraft climbs out, it remains within the controlled airspace and can receive timely instructions from departure control, which enhances safety and operational efficiency. By contacting at this distance, pilots ensure that they are within a manageable distance for the controller to provide necessary routing and altitude assignments as needed for the flight's continued ascent from the departure airport.

The other distances do not align with standard operating procedures for the T-6A, as contacting at those points may result in too early or too late communication, potentially leading to misunderstandings or gaps in information dissemination between the aircraft and air traffic control.
