1. (aviation) Describing the tendency of a plane to roll in the same direction as yaw.
   • 1995, Jan Roskam, Airplane Flight Dynamics and Automatic Flight Controls, page 117:

2. Favourable; in line with one's interests or desires.

   Antonym: adverse

   • 1994, Earl F. Hoerner, Head and Neck Injuries in Sports, page 322:

   • 1999, Missouri Law Review, volume 64, page 770:

     When a process of proverse selection has run its course, a disproportionate number of high-risk insureds will remain in the former classification, which will prompt an increase in the premiums charged in order to cover the higher losses.

   • 2014, Timothy S Hall, “The quantified self movement: Legal challenges and benefits of personal biometric data tracking”, in Akron Intellectual Property Journal, volume 7, number 1:

     Proverse selection is the opposite of the more familiar "adverse selection" problem in which individuals who know or suspect that they will need insurance are more likely to apply for it. […] Proverse selection […] operates as an incentive to reveal positive information about one's risk profile, even if not required (or, sometimes, even if prohibited).

   • 2016, Tenkasi R. Subramanian, Adam R. Khol, Hanumanthrao Kannan, Eliot H. Winer, Christina L. Bloebaum, Bryan Mesmer, “Understanding the Impact of Uncertainty on the Fidelity of the Value Model”, in 54th AIAA Aerospace Sciences Meeting:

     Horace twists the Homeric strands used by Vergil by a further twist when he in turn plays the Vergilian game and points to a proverse and converse relationship between Agrippa and Meriones in the same way as Vergil had created proverse and converse relationships between Diomedes and Aeneas/Augustus.

   • 2008 April, Roelof Vos, Ron Barrett, Daniel Zehr, “Magnification of work output in PBP class actuators using buckling/converse buckling techniques”, in 49th AIAA/ASME/ASCE/AHS/ASC Structures, Structural Dynamics, and Materials Conference:

     This paper explores the new field of active control of proverse (conventional) and converse buckling in piezoelectrically actuated beams using Post-Buckled Precompressed (PBP) elements.

   • 2019, Igor V Chekulay, Olga N Prokhorova, Vladislav A Kuchmisty, “The Mechanisms of Proversion and Reversion in Producing the Compounds of the English Language”, in Vestnik Volgogradskogo gosudarstvennogo universiteta. Seriya 2, Yazykoznanie [Science Journal of Volgograd State University. Linguistics], volume 18, number 1, page 170:

     The subject-matter of this paper is the structural mechanism of the proverse and reverse word-compounding as a word-building process in modern English while having the model of word-combination as a starting basis for such transformations.

   • 1971, Guzārish, page 39:

   • 1970, T. P. Crimes, J. C. Harper, Trace Fossils, page 457:

     The divide between proverse and obverse markings is obvious, particularly in resting burrows which form the most common type in this group.

   • 2007, Adolf Seilacher, Trace Fossil Analysis, page 192:

     Proverse scratches are due to a headdown attitude of the body, whereby only the diggings of the anterior legs are preserved in the undertrace (Pl. 13).

   • 2008, Mary-Ruth Kotelnicki, Remnants of Cruising Trilobites, page 31:

     The proverse direction of leg marks in the anterior and long, deep endopodal scratches make Form A strikingly similar to the Upper Cambrian or possibly lowermost Ordovician (Seilacher 2007) Australian Rusophycus latus Webby, a rusophyciform version of the Upper Cambrian Omani Cruziana omanica (Seilacher).
