Missed approach

As a missed approach ( engl. missed approach, MA ) refers to an aborted for safety landing. Cancellation is done through the through off of the aircraft. In case of an approach under instrument flight rules (IFR ) the appropriate missed approach procedure is initiated immediately.

Causes of a missed approach

Possible causes of a missed approach include:

• Reached the obstacle clearance limit OCA / H without visual contact with the runway or approach lights during instrument flight (see also: missed approach point)
• Runway safety area or (one stripe) not free
• Decision of the pilot responsible for certain reasons
• Violation of the critical area, thus fluctuations in the ILS signal (LOC or GP)
• Unpredictable weather conditions (eg wind gusts) during placement
• Miss all the arresting wires on an aircraft carrier

Missed approach procedure

For flights under visual flight rules, it is up to the pilot to assess in a missed approach the situation and act accordingly. When brought for airfield has a control zone, the air traffic control where necessary give directions.

For flights under instrument flight rules a missed approach ( missed approach procedure ) is well defined and published in the relevant approach chart for each available at an airfield approach procedure. Each procedure has a defined start and end point and granted the pilot obstacle clearance.

Usually, the missed approach procedure consists of three phases: the initial phase begins once the MAPt and used to initiate a go-around. It ends when the aircraft passes into the climb (start of climb, SOC). In the following intermediate phase of the climb is continued and the crew begins with any course corrections. When an obstacle clearance of 50 m is reached safely, begins the final phase. Usually (curves ) are mandatory only in this phase rate changes. The last phase ends when another approach, a holding pattern or the onward flight to another airfield is initiated.
