, 3. What minimum visibility is required for a CAT I ILS approach?
A. 1 statute mile
B. 1/2 statute mile or 1800 RVR
C. 2400 RVR
D. 300 feet RVR
Correct Answer: B
CAT I approaches require at least 1/2 SM visibility or 1800 RVR.
4. What does Mach buffet indicate at high altitude?
A. Structural failure
B. Approaching critical Mach number
C. Stall due to low airspeed
