Make sure you're at the recommended altitude (600-1,000 feet AGL) per ACS guidelines. Begin a turn around the point, keeping asteepest bank angleon the downwind, where your groundspeed is highest. your groundspeed begins to slow down),shallow your bank angleto compensate for the decreasing groundspeed.

IN-FLIGHT ALERTS 500 AGL Alerts – Alerts when descending through 500 ft. AGL after having been above 1,000 ft. The alert will only sound once every 60 seconds and is automatically disabled if groundspeed is less than 40 knots. AGL (or when AGL is unknown), the descent rate exceeds 4,000 ft. per minute AGL.

As an example, the Garmin GTN series offers a vertical calculation (VCALC) function that includes the ability to set a desired rate of descent to calculate the appropriate point to begin your descent based on your aircrafts current groundspeed. In our example: 167kts / 2 = 83.5 Convert to mileage from destination if desired: To convert 13.2

At what AGL altitude will the aircraft be in a stable/configured condition? (No FAA parameters are no lower than 500’ AGL for stabilized criteria What specific runway lighting do we expect to see? The rule of thumb is VSI = ½ groundspeed times 10. What procedures will be followed in the event of a ground proximity warning?

The airplane will be flown at 1,000’ AGL parallel to and at an equal distance from the field boundaries – about ½ – ¾ miles from the boundary as you would fly a traffic pattern. The entry into the maneuver should be accomplished downwind as you would enter the traffic pattern where groundspeed will be the greatest.

Youll want to perform any ground reference maneuver between 600 and 1000 feet Above Ground Level (AGL). Expect an increase in groundspeed, and use smooth inputs on the controls to return to your original heading. Establishing Your Altitude and Airspeed Consistency is key. Choose an altitude and airspeed, and stick with it.

FAA weather charts can help for higher altitudes but when just a few thousand feet agl, they may be less useful. Using my 80-knot tailwind and a stationary wave, my groundspeed and therefore penetration speed through the wave would be 160 knots faster than an upwind approach and theoretically more turbulent. We didn’t test it.
