How far in advance can a pilot request a DTO?

A pilot can request a Direct Transmission Order (DTO) up to 24 hours in advance. This timeframe allows for adequate planning and ensures that necessary adjustments can be made. Requesting a DTO within this window helps streamline operations while aligning with regulatory requirements for flight planning and compliance. It provides a balance between flexibility for the pilot and the operational needs of the aviation system, contributing to safety and efficiency in air travel. The ability to request up to 24 hours in advance also helps in ensuring that any changes in flight plans can be managed effectively without compromising the schedule.
