 Private flying is most associated with the traditional form of factory @-@ produced two and four @-@ seater , single piston @-@ engine training and touring aircraft . Examples of these are the Cessna 152 , Cessna 172 , and Piper PA28 Cherokee , all with their origins in the 1950s , and the more modern designs of Cirrus . The average cost per hour to fly such aircraft has been estimated to be £ 133 , compared to an estimated £ 77 per hour for gliders , and a reported £ 35 per hour for microlights . Recent trends have seen an increase in the use of microlights , and also in recreational helicopter flying following the introduction of smaller and cheaper machines such as the Robinson R22 and R44 . Another growth area in private flying in recent years has been in the use of amateur built aircraft , such as the Van 's Aircraft RV @-@ 4 and the Europa .
