Understanding Decision Altitude [Aeronautics and Space]: A Key Concept in Aviation Safety
Definition & Meaning
Decision altitude (DA) is a critical point in aviation, specifically during instrument approach procedures. It refers to a designated altitude at which a pilot must make a decision: either to continue the approach to land or to initiate a missed approach if the required visual references are not visible. This altitude is measured in feet above mean sea level and is essential for ensuring safe landings in low visibility conditions.

Legal Use & context
In legal contexts, decision altitude is primarily relevant to aviation law and regulations enforced by the Federal Aviation Administration (FAA). It is crucial for pilots, air traffic controllers, and aviation professionals to understand DA as it relates to safety protocols during flight operations. Users can manage related legal documents, such as flight operation guidelines and safety compliance forms, through resources like US Legal Forms.
Key legal elements
Real-world examples
Here are a couple of examples of abatement:
For instance, during an instrument landing approach, a pilot reaches the decision altitude of 200 feet. If the pilot does not see the runway or other required visual references, they must execute a missed approach to ensure safety. This is a crucial decision-making point in the landing process.

Key Differences
Decision Height (DH)
The altitude at which a decision must be made during a precision approach.
DH is used in precision approaches, while DA is used in non-precision approaches.
Missed Approach Point (MAP)
The point in an approach procedure where a missed approach must be initiated if visual references are not acquired.
MAP is a specific location, while DA is an altitude.
Common misunderstandings
What to do if this term applies to you
If you are a pilot or involved in aviation operations, ensure you are familiar with decision altitude protocols and the specific requirements for your aircraft and flight path. Consider utilizing US Legal Forms for templates related to aviation safety and compliance. If you have questions or face complex situations regarding aviation law, it may be beneficial to consult a legal professional with expertise in aviation regulations.
