Cities across Europe are plan­ning ver­ti­port infra­struc­ture. Air­craft devel­op­ers are pro­gress­ing through cer­ti­fi­ca­tion. Investors are com­mit­ting cap­i­tal. But beneath this momen­tum, a crit­i­cal ques­tion remains unan­swered: who is legal­ly respon­si­ble when some­thing goes wrong at a ver­ti­port?

EASA pub­lished the world’s first Pro­to­type Tech­ni­cal Design Spec­i­fi­ca­tions for ver­ti­ports in March 2022 and is devel­op­ing a com­pre­hen­sive reg­u­la­to­ry frame­work under Rule­mak­ing Task (RMT) 0230. The tech­ni­cal foun­da­tions are steadi­ly being laid.

The Lia­bil­i­ty Ques­tion Nobody Is Answer­ing

A ver­ti­port is not sim­ply a land­ing pad. It is a com­plex oper­a­tional node where air­craft, ground infra­struc­ture, ener­gy sys­tems, pas­sen­ger ser­vices, dig­i­tal traf­fic man­age­ment, and emer­gency response con­verge. When an inci­dent occurs (a land­ing fail­ure, a bat­tery fire, a ground col­li­sion, or a pas­sen­ger injury), respon­si­bil­i­ty may involve any com­bi­na­tion of the air­craft oper­a­tor, the ver­ti­port oper­a­tor, the eVTOL man­u­fac­tur­er, the U‑space ser­vice provider, the ener­gy sup­pli­er, or the ground han­dling com­pa­ny.

Yet despite the exis­tence of har­monised EU avi­a­tion reg­u­la­tions, there is cur­rent­ly no com­pre­hen­sive Euro­pean frame­work specif­i­cal­ly allo­cat­ing respon­si­bil­i­ty and lia­bil­i­ty among the var­i­ous actors with­in the ver­ti­port ecosys­tem.

Instead, nation­al tort law con­tin­ues to fill that gap dif­fer­ent­ly across Mem­ber States. As a result, the same inci­dent at a ver­ti­port in Milan could lead to a dif­fer­ent allo­ca­tion of respon­si­bil­i­ty, a dif­fer­ent liable par­ty, and ulti­mate­ly a dif­fer­ent lev­el of com­pen­sa­tion than an oth­er­wise iden­ti­cal inci­dent in Ham­burg or Paris.   

For cities con­sid­er­ing whether to approve ver­ti­port con­struc­tion, that uncer­tain­ty is not an abstract legal issue. It is a plan­ning risk that direct­ly affects invest­ment deci­sions, pub­lic pro­cure­ment, and long-term oper­a­tional gov­er­nance.

Insur­ance With­out a Map

Insur­ers face a par­al­lel chal­lenge. Ver­ti­port oper­a­tions com­bine avi­a­tion risk, infra­struc­ture risk, ener­gy risk, cyber risk, and pub­lic lia­bil­i­ty with­in a sin­gle oper­a­tional envi­ron­ment, a risk pro­file that tra­di­tion­al avi­a­tion insur­ance prod­ucts were nev­er designed to address.

With­out greater clar­i­ty regard­ing how respon­si­bil­i­ty and lia­bil­i­ty are allo­cat­ed among the dif­fer­ent actors oper­at­ing with­in a ver­ti­port, insur­ers face dif­fi­cul­ties in pric­ing prod­ucts that accu­rate­ly reflect the under­ly­ing allo­ca­tion of risk. The result, as increas­ing­ly seen in oth­er emerg­ing avi­a­tion sec­tors, is that legal uncer­tain­ty itself becomes part of the pre­mi­um, rais­ing costs for oper­a­tors and poten­tial­ly slow­ing com­mer­cial deploy­ment.

The recent­ly adopt­ed Prod­uct Lia­bil­i­ty Direc­tive (EU) 2024/2853, which express­ly cov­ers soft­ware and AI-enabled sys­tems, fur­ther broad­ens the range of poten­tial lia­bil­i­ty expo­sure for ver­ti­port oper­a­tors rely­ing on auto­mat­ed ground man­age­ment and dig­i­tal traf­fic coor­di­na­tion.

The Gov­er­nance Gap

EASA’s tech­ni­cal spec­i­fi­ca­tions address ver­ti­port design: phys­i­cal char­ac­ter­is­tics, obsta­cle-free vol­umes, visu­al aids, light­ing, and emer­gency access. These are essen­tial.

But they do not address who bears insti­tu­tion­al respon­si­bil­i­ty for the safe oper­a­tion of a ver­ti­port as an inte­grat­ed oper­a­tional ecosys­tem. Who is account­able when charg­ing infra­struc­ture fails and an air­craft can­not divert safe­ly? Who is respon­si­ble when a vertiport’s dig­i­tal traf­fic man­age­ment sys­tem con­flicts with the U‑space ser­vice provider man­ag­ing the sur­round­ing air­space? Who ensures the integri­ty of oper­a­tional data flow­ing between inter­con­nect­ed sys­tems oper­at­ed by dif­fer­ent com­mer­cial actors?

These are gov­er­nance ques­tions, not engi­neer­ing ques­tions. And they remain large­ly unan­swered.

What Needs to Hap­pen

Three steps could sig­nif­i­cant­ly improve legal pre­dictabil­i­ty for ver­ti­port devel­op­ment.

First, EASA could con­sid­er com­ple­ment­ing its work under Rule­mak­ing Task (RMT) 0230 with guid­ance estab­lish­ing min­i­mum prin­ci­ples for allo­cat­ing respon­si­bil­i­ties between ver­ti­port oper­a­tors, air­craft oper­a­tors, and dig­i­tal ser­vice providers.

Sec­ond, munic­i­pal­i­ties approv­ing ver­ti­port con­struc­tion need prac­ti­cal guid­ance on the gov­er­nance and account­abil­i­ty frame­works that should under­pin these facil­i­ties ‑before, not after- they are built.

Third, the insur­ance sec­tor needs ver­ti­port-spe­cif­ic risk cat­e­gories that bet­ter reflect the unique com­bi­na­tion of avi­a­tion, infra­struc­ture, dig­i­tal tech­nol­o­gy, and ener­gy risks these facil­i­ties present.

Cities and oper­a­tors that estab­lish clear gov­er­nance frame­works ear­ly will attract invest­ment faster, secure bet­ter insur­ance terms, and posi­tion them­selves as pre­ferred launch loca­tions for eVTOL oper­a­tors. Legal infra­struc­ture is not a cost of doing busi­ness. It is a com­pet­i­tive advan­tage. 

Ver­ti­ports are where urban air mobil­i­ty meets the ground, lit­er­al­ly and legal­ly. Get­ting the phys­i­cal infra­struc­ture right is essen­tial. Get­ting the legal infra­struc­ture right will deter­mine whether it scales.
