How To Fly A Continuous Descent On Final Approach Cdfa Boldmethod We'll cover how to fly a non precision approach. unlike a precision approach like an ils, there is no vertical guidance on a non precision approach. even without this though, we can still figure. Present npas are designed with and without stepdown fixes in the final approach segment. stepdowns flown without a constant descent will require multiple thrust, pitch, and altitude adjustments inside the final approach fix (faf). these adjustments increase pilot workload and potential errors during a critical phase of flight.
Conducting A Stabilized Non Precision Approach Using Cdfa Continuous Fortunately, the faa and jeppesen are making things a bit easier and safer for all of us, by publishing a continuous descent on final approach (cdfa) for most non precision approaches. The final approach segment may have zero or more step downs to a minimum descent altitude (mda). the pts technique for flying a non precision approach is to descend to the mda, level off, remain at mda until you are in position to land, or until you reach the missed approach point. this is colloquially known as the dive and drive approach. Cdfa is a technique for flying the final segment of a non precision approach as a constant descent (without level off) from the faf altitude to approximately 50 ft height above the landing runway threshold. It does not provide vertical guidance like a precision ils approach. just like a vor or localizer approach then, a gps approach with lnav minimums is a non precision approach. also, like any non precision approach, it has a minimum descent altitude, an mda. this one is 1,140 feet for all category aircraft.

A continuous descent final approach is what you do for every straight in ils and what you attempt to do for every visual straight in: you hit the glide path and start down on an angle that ends up in the touchdown zone of the runway. you can also do this when in instrument conditions flying a non precision approach, which we should probably call an "approach without vertical guidance.". 2.definitions | minimums mda (minimum descent altitude) lowest altitude the approach descents to (specific criteria needs to be met before descending further) may level off at the mda until the missed approach point used in non precision approaches da dh (decision altitude height) altitude where decision is made to land or execute missed appr.
