National air regulations apply
In the UK, for example, the airship being a UAV is exempt from
CAA regulations but is restricted to a maximum operational height
of 400ft (120m) above ground level (AGL). Additionally, local
airspace restrictions may apply in certain areas (close to airports
and airfields, etc.).
Obviously we will comply with these regulations and this may
affect your operating requirements. Generally speaking, however,
pro-active planning and liaison keeps everyone happy.
