1.Is RWY 35 equipped with an approach lighting system? If so, what action must be taken to turn them on at 0300 hours local?
Yes, note ARCAL (K) in top right corner of approach plate.

2.Arrival control's radar is U/S at the time of the approach and CYA228 is active. What (if any) effect does this have on the approach?
The approach is not authorized as per the note on the left-hand border. 

3.Landing minima for ILS approaches is normally 200 and ½. For what reason are they 250 and 1 on this approach?
This approach is not equipped with a high intensity approach lighting system.

4.You are level at 7,000 feet inbound on the 240-degree transition to TARTI from YYC for the full procedure ILS approach. The procedure turn must be accomplished within ___ NM of TARTI.

5.What is the clearance limit of this approach, and what should be your course of action if you arrive there prior to receiving further clearance?
The clearance limit is the PIGEON NDB, and you should enter the published hold and request further clearance. 

6.Your aircraft is equipped with a new generation avionics system but it is not ADF equipped. How does this affect you with respect to flying this approach?
The approach is not authorized as you do not have the navigation aid that the missed approach is based on. Since this approach is based on traditional navaids, the aircraft must be equipped with the navaid that it is based upon (ADF)..
