I suggest that you get yourself a proper Cirrus instructor, you must understand the system if it will ever help you.
If you are serious about flying a Cirrus SPEND $50 and join COPA
www.cirruspilots.org and then read and search the members forums.
For your instructor to give you such bad advise "don't pull over land" is unbelievable. HE does not understand what its for, and you can only get as good as he is able to teach.
What else does he not know? Has he taught you about alternator or flap failures? or brake failures? or "gotchas" in the Avionics, or how to ensure your fuel is balanced and correct, or how to even lean the thing properly?
I would be suprised if this guy knew how to lock the doors. The CAPS system could save your life one day, and HE is not prepared to learn about it and teach you some seanarios and decision trees?
If you haven't thought this thru and practiced it in your mind: when, where and how you might use this, then in an emergency you will freeze and forget a life saving option.
Do the RAF let their pilots fly a Harrier without training them on the ejection seat?
Phew!
