There have been a couple of incidences in the last few weeks where, for a variety of reasons, we have found ourselves operating without the airspace being opened. As tug pilots, we can help by making a call to the office before the first aerotow of the day. It will serve as a radio check and the information received, for example; Luton 26 with CT8 available, will ensure the airspace has been opened.
I suggest you write on top of the tug card the airspace given. If the airspace changes during the day this should also be written on the card along with the time of change.
