The 180-Degree Power-off Approach

By Pia Bergqvist / Published: Jun 05, 2012

One maneuver that has been added to the practical test standards since I earned my commercial and instructor certificates at the beginning of the millennium is the power-off 180-degree accuracy approach and landing. While this maneuver is not a part of the private or sport pilot curricula, it is a maneuver that is worthwhile for you to practice regularly with an instructor by your side.

The power-off 180-degree accuracy approach and landing is exactly what the name implies. You select a point on the runway, most likely the 1,000-foot markers, cut the power on the downwind leg abeam the target point (at or below 1,000 feet agl per the PTS) and leave the power off for the duration of the approach with the intent to land as close to the preselected point as possible.

Naturally, you will have to make adjustments for wind conditions in order to make your spot, so you may need to slip the airplane and use flaps as necessary in order to make it. But don’t be so focused on hitting your target that you forget to keep the airplane in a safe attitude. And make sure you become intimately familiar with this type of approach with an experienced instructor by your side before ever attempting it on a solo flight.

Since different airplane types have different glide ratios it’s worth practicing these types of landings in each type of airplane you fly regularly. When I practice accuracy power-off landings in the Cessna 170, for example, I need to make my base turn almost immediately after I cut the power on the downwind. Otherwise I will need to add power in order to make it to the threshold. However, if I make the turn at the same point in a Cessna 172, I would most likely end up way past my selected target even with a slip.

Accuracy power-off landing practice is a terrific challenge and it also prepares you for the highly unlikely, but not impossible case of an engine failure. Knowing how the airplane will behave without power and how the approach needs to be planned greatly increases the chances of a successful unplanned power-off approach.

OK, so I've been at it over 40 years, but that is the way I learned back then, and I still do exactly that on most all approaches, and taught others to do the same. You know you can make the field when this becomes second nature. I despise the 5 mile final and dragging it in.

Had to do it in training two seaters and my first AUW sign-off in the 172 in the oldie days so not sure what has changed. I hate the word review but it might be time to review some of the training requirements/regulations with a bit more emergency situation training. In the latter stages of my PPL my instructor would make me do EFATO, 180 engine off, forced landings anytime. Saved my butt when the primer vibrated out - went through the procedures like clockwork - sorted, landed, fault register, aircraft out of service, to the bar, aircraft back in service ,second solo same aircraft, different day.

Got my training and ticket eleven years ago and this maneuver was a requirement then. So, really not sure what has changed for the private ticket today. As above has mentioned, this remains a good discipline to follow for most landings. I've never felt comfortable dragging the airplane in on final.

A long time ago, this was required on the private, commercial and instructor's flight test. When did it go away? One more case of the government dumbing down the standards. Also, another arguement for replacing the useless medical certification with a couple of hours of annual real flight instruction on emergency procedures. The bi-annual seems to be more concerned about one's memory of the constantly expanding airspace rules. One point of focus after the 180 and land within 200 feet of the designated point (after, not before!) would be to teach some planning skills regarding fuel management. We should all be alarmed at how many fuel outages are reported and one wonders how many go unreported. Lot runway incurrisions, it should not happen.
