Answer
- B The vertical speed indicator shows zero
- C The altimeter freezes at the altitude at which the blockage occurred
Explanation
Without access to the outside pressure, the pressure of the blockage altitude remains in the system. The altimeter stops moving, and the vertical speed indicator shows zero. The airspeed indicator under-reads in the climb because the trapped static pressure is higher than the actual one.
