Purpose of DA FORM 3501-1

The DA FORM 3501-1 is designed to provide comprehensive data related to Precision Approach Radar (PAR) operations. PAR systems are critical in guiding aircraft during final approach, particularly when pilots cannot maintain visual contact with the ground due to poor weather conditions like fog, rain, or low clouds.

How DA FORM 3501-1 Enhances Aviation Safety

Role in Ground Controlled Approaches

Ground Controlled Approach (GCA) is a radar-based system used to guide aircraft safely to the runway when pilots cannot see the ground. The DA FORM 3501-1 contains essential data that radar operators use to monitor and communicate with pilots during these critical phases of flight.

Importance in Low-Visibility Conditions

In scenarios where pilots face low-visibility conditions, the DA FORM 3501-1 becomes particularly important. The form provides radar operators with the necessary information to assist pilots in aligning with the runway and achieving a safe landing altitude and speed.

Detailed Components of DA FORM 3501-1

Data Fields Included in the Form

While the form’s specific content is designed for use by trained personnel, some of the key data fields include:

  • Aircraft position: Coordinates and altitude information.
  • Radar data: Details about the aircraft’s speed, trajectory, and any adjustments needed.
  • Communication logs: Records of interactions between the aircraft and radar operators.
  • Weather conditions: Information on visibility, wind speed, and other meteorological data affecting the approach.

Using DA FORM 3501-1 in Military Operations

The form is used extensively in military aviation training and operations. It helps ensure that pilots and radar operators are fully prepared to conduct safe landings under a wide range of conditions, enhancing the overall effectiveness and safety of military aviation missions.


DA FORM 3501-1 – Precision Approach Radar (GCA) Data is a critical tool in the U.S. Army’s aviation operations. By providing detailed data for use in Ground Controlled Approach systems, this form significantly contributes to the safety and precision of aircraft landings, especially in adverse weather conditions. Understanding and utilizing DA FORM 3501-1 effectively is essential for personnel involved in military aviation and related fields.
