Question 1

What category is the PC-21 to be operated at? Why is it not CAT B?

Answer 1

CAT C even through the PC-21 fits within CAT B based on Vat, its actual handling speeds are in excess of those listed for a CAT B aircraft.

Question 2

With respect to NAVAID requirements for alternate calculations, what independent navigational equipment does the PC-21 have?

Answer 2

1) VOR and ILS - two independent receivers
2) TACAN-DME - one independent transmitter-receiver
3) GLSSU - two receivers which can be considered independent provided that:
- Both seats are occupied or
- For solo ops:
- The RNAV approach for the destination or
alternate is to be loaded in the active flight plan
for the forecast arrival runway with no
discontinuities prior to TO
- IF an alternate is required for a destination that
has no ground based NAVAIDS, a suitable
alternate must be calculated on an approach
other than RNAV

Question 3

How should RADALT be set to during an instrument approach?

Answer 3

1) HAT or next settable height for a 3D approach
2) 250 ft for a 2D SI approach with a FAF
