Similarly, the text refers
to ‘smaller drones’ - does this refer to any ‘sub 25kg’ drone, or to a
lower sub division such as the ‘very small drones’ as described in
CAT A1 ?

Mrs Hill explained that for the year ahead the key priorities that the
CAA would need to exert influence upon would be: the Commission’s Aviation
Package, the changes to the EASA Basic Regulation, progressing the SES+2
proposal, reviewing the Denied Boarding and Compensation Regulation, the
Commission’s work plan on RPAS, and introducing performance based
regulation to any EASA work on security and cyber security.

Usage of Unmanned Aircraft
There are many benefits of utilising UAVs within the hospital estate for inspections and
survey work, and likewise with cargo drone RPAS systems intra-hospital.

Readers should take care though in
extrapolating the work that is presented here to the behaviour of small drones and UAVs where these
secondary effects may indeed start to become important.
