The inspection flights in Portugal laid us from south to north and from the Atlantic Sea shore to the border to Spain
Demanding flight preparation
Gas pipeline inspection was made for the first time with a Helicopter – accordingly the flight preparation was demanding. Securing the requisite permits traversing control zones: e.g. International Airport Lisbon, restricted Military Zones as well as NATO Training Zones and special requisite permits to enter Prohibited Aereas.
