Click the question to see the answer

1. You are level at 5000 feet 5 NM east of PETSU and cleared for this approach in ISA conditions. You can now descend to _____ to be in a better vertical position for the approach.
Sector altitude of 2800 ASL

2. Sector altitudes provide for ____ feet of obstacle clearance.
1000 

3. After crossing PETSU, continue descent to ____.
Technically 2600, but operationally better to target 2700 as the Constant Descent Approach (CDA) indicates final approach descent from 2700.

4. To fly the CDA from 2700, you should initiate descent at ____ NM back from NADUR.
 0.3 back from NADUR equates to 5.3 NM back from RW03. Note the approach profile.. 

5. With a groundspeed of 120 knots, you should target a sink rate of ____ FPM to fly the descent profile.
635 FPM. Interpolate between 110 and 130 numbers. 

6. What minimum ceiling and visibility would be needed to achieve the required visual reference to land from this approach and is this runway RVR equipped?
Ceiling of 500 feet and prevailing visibility of 1 SM. Yes, this runway is RVR equipped, note 1 RVR 50 in landing minima. 

7. What should be your course of action in the event of a missed approach?
Hold as published at PIVOD at 3100 via a direct entry.
