===Pilot error===
[[Pilot error]] is the most common cause of control reversal. In [[unusual attitude]]s it is not uncommon for the pilot to become [[Spatial disorientation#Senses during flight|disoriented]] and make incorrect control movements to regain level flight. This is particularly common when using [[Helmet-mounted display|helmet-mounted display systems]], which introduce graphics that remain steady in the pilot's view, notably when using a particular form of [[attitude indicator|attitude display]] known as an ''inside-out''.<ref name="jenkins-hmd">{{cite journalthesis |last1=Jenkins |first1=Joseph C. |title=The Effect of Configural Displays on Pilot Situation Awareness in Helmet-Mounted Displays |date=2007 |url=https://corescholar.libraries.wright.edu/cgi/viewcontent.cgi?article=1297&context=etd_all |publisher=Wright State University |bibcode=2007PhDT........44J |access-date= December 19, 2021 |format=pdf |degree=PhD |others=Jennie Gallimore (Advisor)}}</ref><ref name="aviatn-psych-outside-in">{{cite journal |last1=Previc |first1=Fred H. |last2=Ercoline |first2=William R. |title=The 'Outside-In' Attitude Display Concept Revisited |journal=The International Journal of Aviation Psychology |date=October 1999 |volume=9 |issue=4 |pages=377–401 |doi=10.1207/s15327108ijap0904_5 |url=https://www.researchgate.net/publication/232896204 |access-date=December 19, 2021}}</ref>
 
===Incorrectly connected controls===
Incorrectly connected controls are another common cause of this problem. It is a recurring problem after maintenance on aircraft, notably home built designs that are being flown for the first time after some minor work. It is not entirely uncommon on commercial aircraft, and has been the cause of several accidents including the crash of the [[Short Crusader]] before the 1927 [[Schneider Trophy]] and the 1947 death of [[Avro]] designer [[Roy Chadwick]].<ref name="avsafety-G-AGSU-crash">{{cite web |last1=Ranter |first1=Harro |title=ASN Aircraft accident Avro 689 Tudor 2 G-AGSU Woodford Airport (WFD) |url=https://aviation-safety.net/database/record.php?id=19470823-0 |website=aviation-safety.net |publisher=Aviation Safety Network |access-date=19 December 2021 |quote=''PROBABLE CAUSE: Incorrect assembly of the aileron control circuit.''}}</ref>
