Difference between MDA and OCA?
MDA is minimum descent altitude, you can descend to MDA in IMC, but not below.
If you gain visual reference at the MDA, you can descend visually from the MDA to not below the OCA (daytime procedures) and circle. You cannot go below OCA until established on final for the landing runway. The OCA is performance category dependent in PANS-OPS (Cat C = 400') or 400' in australian old criteria charts.
Some more interview/renewal questions from the ITCZ vault.
Questions:
1. What are the Category B speeds?
2. What determines Cat A, B, C, or D?
3. What are the conditions for descent below the minima (circling day, circling night and straight in)?
4. What is the minimum taxi distance behind turboprops and jets (a) taxiing and (b) requiring breakaway thrust?
5. What is the minimum distance from objects when activating the Wx radar on ground with antennae rotating, stationary, and what objects must be outside this distance?
6. What are suitable and adequate aerodromes?
7. What limits apply to the IFR altimeter checks?
8. What are the conditions for visual approach, night and day?
9. What are your actions if landing gear is not locked down after normal selection? (ATC/procedures, not the manufacturer drill to get em down)
10. What are the conditions on conducting straight in approaches to CTAF?
11. Which Australian aerodomes use LAHSO procedures? Can you participate as active or passive?
12. When does a Notam become a 'one-liner'?
13. What does Nil Current with respect to a Notam mean?
14. What fuel reserves apply to normal, one inop and depressurised ops/PNR?
15. What are the speed limitations in the holding pattern?
16. When are your required to plan for an alternate aerodrome?
17. When can you use Special Alternate Minima?
18. You are planning to depart ASP RW12 to the north in IMC. How do you ensure terrain clearance until established above LSALT on track?
19. You are an IFR flight planning AS for TNK, you are having trouble getting an AVFAX briefing. What are the minimum briefing materials you require prior to departure?
20. When is a FROM period valid in an aerodrome forecast? Is different if the FROM is in a TTF?
21. How many flight attendants do you require in the cabin whilst refuelling?
22. What is the wake turbulence separation standard for a Medium category aircraft departing behind: a B747, a Metro, a Chinook?
