Click the question to see the answer
1)Which waypoints within this procedure would be classified as fly-over waypoints?
RW25 and ADVUS. Check CAP GEN Legend.
2)What type of GPS is required to fly the LPV approach, and what minimum ceiling and visibility would be required to achieve the required visual reference for landing?
A WAAS-equipped IFR certified GPS is needed and a corresponding ceiling of 300 feet and 1 SM visibility should get you in.
3)If equipped with an IFR certified GPS (non-WAAS), which approach would offer us the lowest minima, and what minimum ceiling and visibility would be required to achieve the required visual reference for landing?
You should fly the LNAV approach and a corresponding ceiling of 500 feet and 1¼ SM visibility should get you in.
4)If flying the LNAV approach and established on the final approach course at 3,400 feet, at what point should we initiate descent to fly the CDFA approach? This point would correspond to how many NM back from BEROB?
4.4 NM back from BEROB equates to 8.5 NM back from RW25.
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 ADVUS, and you should enter the published hold.
6)How much obstacle clearance is provided at circling MDA?
300 feet.
