Final answer:
Flight Training Units are not generally required to notify the Minister or aviation authorities about the planned routes of solo flight-training flights, but they must ensure that all training flights comply with safety regulations and standards.
Step-by-step explanation:
For solo flight-training flights dispatched from an Flight Training Unit (FTU), the FTU is not typically required to notify the Minister or any aviation authorities in writing or verbally of the planned route of the flight originating from the main base or any satellite base, unless specifically required by national aviation regulations or operational procedures of that country. Instead, the solo flight is performed under the supervision of the FTU, which is responsible for maintaining standards of safety and ensuring that all flights are conducted according to flight training protocols and airspace regulations. It's important for the FTU to have detailed knowledge of the student's planned route and for the student to have a thorough pre-flight briefing, but this internal oversight usually suffices unless additional procedures are stipulated by the relevant national aviation authority.
