…and on VTOLS

Pilot - - NOTES -

EASA has also re­leased what it calls ‘the first build­ing block’ to en­able the safe op­er­a­tion of hy­brid and elec­tri­cal ver­ti­cal take­off and land­ing air­craft. Its aim is ‘to pro­vide the frame­work for man­u­fac­tur­ers to de­velop in­no­va­tive per­son-car­ry­ing VTOL heav­ier-than-air air­craft in the small cat­e­gory, with lift/thrust units used to gen­er­ate pow­ered lift and con­trol’. This ‘small’ cat­e­gory cov­ers air­craft with pas­sen­ger ca­pac­i­ties of nine or less and MTOWS up to 3,175kg.

Two cer­ti­fi­ca­tion cat­e­gories are pro­posed, Ba­sic and En­hanced, linked to the in­tended type of op­er­a­tion, says EASA. ‘A di­rect re­la­tion­ship be­tween air­wor­thi­ness and types of op­er­a­tions al­ready ex­ist, for example when cer­ti­fy­ing for VFR or IFR op­er­a­tions. In­tro­duc­ing this ad­di­tional link pro­vides greater scal­a­bil­ity in set­ting safety ob­jec­tives and al­lows to as­sign the high­est safety lev­els of Cat­e­gory En­hanced to pro­tec­tion of third-par­ties when fly­ing over con­gested ar­eas and com­mer­cial air trans­port of pas­sen­gers. Op­er­a­tional rules can then be built on demon­strated air­craft safety lev­els and adapted as nec­es­sary to local par­tic­u­lar­i­ties. The cur­rent reg­u­la­tory frame­work has ini­tially been de­signed for con­ven­tional fixed-wing air­craft, ro­tor­craft, bal­loons and sailplanes. Propul­sion was mostly pro­vided by pis­ton or tur­bine en­gines us­ing fos­sil fu­els. The in­tro­duc­tion of new tech­nolo­gies and con­cepts of air trans­port re­quires to re­visit this frame­work.’
