Flashcards

ETA (Estimated Time of Arrival)

The estimated time of arrival for an aircraft at a designated point, typically used in IFR (Instrument Flight Rules) operations. For IFR flights, this point is usually defined by reference to navigation aids, marking the start of an instrument approach procedure. If no navigation aid is associated with the aerodrome, it refers to the estimated time of arrival over the aerodrome.

ETD (Estimated Time of Departure)

The estimated time of departure for an aircraft, indicating when it is anticipated to leave its origin.

Directorate General of Civil Aviation (DGCA)

The highest governing body for Indonesian civil aviation, responsible for setting regulations and ensuring safety.

Civil Aviation Safety Regulations (CASR)

A set of regulations governing civil aviation in Indonesia, based on international standards like ICAO Annexes.
