Southwest 1704 The Southwest sector of ZDV airspace covers a large portion of the western United States, including parts of Colorado, Utah, Arizona, New Mexico, and Nevada. The Southwest 1704 radial extends from the Denver VOR/DME navigation aid in a southwesterly direction, and serves as a reference point for air traffic control in this sector. Air traffic controllers use the Southwest 1704 radial, along with other radials and navigation aids, to provide guidance and instructions to pilots as they navigate through the ZDV airspace. For example, a controller might instruct a pilot to "fly heading 170, intercept the Southwest 1704 radial, and maintain 10,000 feet." This instruction would direct the pilot to fly in a southwesterly direction towards the Southwest 1704 radial, and then to adjust their course to align with the radial and maintain a specific altitude. The Southwest 1704 radial is just one of many radials and navigation aids used by air traffic controllers to manage the complex and dynamic air traffic in the ZDV airspace. These aids are critical for ensuring the safety and efficiency of air traffic operations, and are constantly monitored and updated to ensure their accuracy and reliability. In addition to its use in air traffic control, the Southwest 1704 radial also plays a role in flight planning and navigation. Pilots and dispatchers use the radial, along with other navigation aids and flight planning tools, to plan and execute safe and efficient flight routes. By aligning their flight paths with the Southwest 1704 radial and other navigation aids, pilots can ensure that they are following the most direct and efficient route to their destination, while also staying within the boundaries of the ZDV airspace. Overall, the Southwest 1704 radial is an important geographic reference point in the ZDV airspace, used by air traffic controllers and pilots to ensure the safe and efficient navigation of aircraft. Its accurate and reliable operation is critical for the safety and efficiency of air traffic operations in this sector, and it is constantly monitored and updated to ensure its continued effectiveness. Southwest 1704 is a designation used by the Federal Aviation Administration (FAA) in the United States to identify a specific geographic location in air traffic control. More specifically, it refers to the 1704 radial (a line extending from a specific point, in this case the Denver VOR/DME navigation aid) of the Southwest sector of the Denver Air Route Traffic Control Center (ZDV) airspace.
