There will be orders written down. Whether or not individual squadrons are adhering to them is largely dependent upon leadership within and above the squadron. A good example of how a squadron specific 'we don't have to follow the rules' culture evolves to a dangerous level is the RNZAF ANZAC day Iroquois crash of 2010.
If anyone reading this is leading a squadron, you need to know the orders, understand your responsibilities to your men, women, and the nation, ( in peacetime and at war), then have the courage to enforce the orders that have been written. It is surprising to me how few 'military leaders' have this fortitude and simply run the show like the last guy did ( ie perpetuate what ever culture they inherited).
