So with my recent renewal of my PFAW, I decided to apply for night operations permissions as there are some opportunities arising where this would come in very useful.
Before this it is prohibited to fly a drone 30 mins after sunset or 30 mins before sunrise. These permissions now allow me to fly anytime of the night as long as I follow more strict protocols, like making sure the take off and landing area is well lit, and a daytime flight survey has been carried out.
