- Description
- The omnidirectional departure is a standard means of departing an aerodrome under instrument flight rule conditions. It is designed to assure that the aircraft has appropriate obstacle clearance at all times from the departure end of the runway to the first point along the predetermined flight plan. The basic procedure for this departure is that the aircraft is to fly the runway heading after takeoff until reaching an altitude of 120 metres (394 feet), and only after reaching this altitude can the aircraft initiate a turn towards the predetermined fligth plan.
