Setting Up for the RNAV Approach
Ray from the MzeroA team begins the flight at 7,000 feet en route to Waco Regional Airport. After receiving instructions from air traffic control to descend to 4,000 feet, he sets up a smooth 500 ft/min descent rate. While visual approaches are being conducted into Waco, he coordinates with Waco Approach to request the RNAV (GPS) Runway 1 approach, allowing him to demonstrate the full instrument procedure.
Configuring the Aircraft for the Approach
With clearance in hand, Ray selects the RNAV Runway 1 procedure, prepares the avionics, and begins configuring the aircraft. Essential steps include setting the altimeter, turning on landing lights, checking fuel quantity, and activating the fuel pump. ATC clears the aircraft to Shale (the initial approach fix) at 4,000 feet. From there, he loads the approach into the flight plan, ensuring the Cirrus is properly set up for descent and alignment with the final approach course.
Briefing and Flying the RNAV GPS Runway 1
The approach briefing covers key details:
- Runway length: 7,000 feet.
- Final approach fix at 2,000 feet.
- Visual descent point (VDP) to ensure a safe descent below decision altitude.
- Minimum descent altitude: 761 feet with .75 mile visibility.
- Missed approach: Full power, flaps up, positive rate, and a climb to 3,000 feet.
As the procedure unfolds, Ray demonstrates how quickly IFR flying develops. He configures the aircraft, slows to approach speed, and follows the glide path while coordinating with Waco Tower. With flaps set and the autopilot tracking the glide slope, he maintains situational awareness while monitoring for traffic and obstacles.
Landing at Waco Regional Airport
Crossing over Lake Waco, the approach presents unique night-flying challenges, such as the “black hole effect” over water. Despite this, Ray maintains a stable glide path, manages airspeed, and disconnects the autopilot before a smooth landing on Runway 1. After rollout, he exits via Alpha 3 and taxis to parking.
This demonstration highlights the importance of preparation, situational awareness, and adaptability when flying instrument approaches. Even in VFR conditions, practicing the full RNAV GPS procedure helps pilots stay sharp and build confidence.
