It seems to me that this is a good time for the IAA to do a full and detailed audit of the Ryanair operation at EGSS during this 36 hr. period.
They could examine the paperwork required for Cat 3 approaches (Do they have a Cat 3 minima card that allows their pilots to modify the minima in case of A/P and ground aid failures?).
The could check the training for low visibility approaches and refresher courses.
They could do a full audit of the duty and rest periods of all crews flying over that period. Were Minimum Rest periods compromised? If so by whom and on whose request.
They could examine whether there a culture of fear within the airline that modifies peoples behaviour.
