Title: Explain regulations related to communications en route.
Course: Aircraft Pilot Training I (20053-I) > Section: Exploring Regulations

Explanation should include the following:

- Radio communications are a critical link in the ATC system. The link can be a strong bond between pilot and controller or it can be broken with surprising speed and disastrous results.
- A position report is required by all flights regardless of altitude, including those operating in accordance with an ATC clearance specifying "VFR-on-top," over each designated compulsory reporting point along the route being flown.
- When flying into airspace that is under the authority of ATC, two-way radio communication is mandatory unless prior arrangements have been made.
- When a pilot receives instruction from ATC, the pilot must comply, as long as compliance does not violate regulations or create an unsafe condition. If the pilot cannot comply with instructions from ATC, the pilot must advise the controller as soon as possible.
