1.What is the highest spot height within the plan view of the approach plate?
4990 ASL

2. You are 40 nm north of TEXEC level at 16,000 feet in IMC and cleared for this approach in standard temperature conditions. What altitude can you legally descend to and which frequency would you expect to be on?
100 NM SAFE of 10,000 and Vancouver Centre on 132.9 

3. If you cross TEXEC at 7,500 ASL and are deemed to be too high to fly the TEXEC - UDBIB transition, what would be your best option?
Shuttle descend to 3,700 feet as published prior to continuing on the transition

4. For reasons of simplicity, if you decide to descend to 2,100 feet, at what point should you initiate final approach descent to MDA?
 As per the table, at 6.2 NM back from RW11, this would coexist with .2 NM back from OVDAD (FAWP). 

5. What is the landing distance available on RWY 11 and is it equipped with a VASIS or PAPI?
4,500 feet, and no VASIS or PAPI. 

6. What is the clearance limit of this approach and what should be your course of action if you arrive there before you receive further clearance?
Initially hold as published at 3,000 at OMINI (direct entry) and with enroute clearance ensure you are at least at 4,300 before proceeding on course. If not at least at 4,300, enter shuttle pattern until climbing through it.
