In The Plane

...	The ACS calls for these to be 600'-1000' AGL
...	...	BUT, on Long Island - 1000' AGL is best!
...	This maneuver should be practiced at various airspeed and flap configurations, as examiners can ask for just about anything!
...	...	In light winds, "slow-flight" configurations are often used on checkrides.

...	We have never seen an examiner ask for this maneuver on a check ride.
...	Your traffic pattern work at the end of the checkride demonstrates it.
...	But be sure to practice it a few times prior to touch and goes, and get it in your logbook!

...	Airman Certification Standards (ACS)
...	...	Calls for At least 1 of the 3 Ground Reference Maneuvers to be demonstrated on your checkride.
...	...	Altitude 600' - 1000' AGL
...	...	Altitude ±100'
