- Clear of clouds

Question 13

SVFR Wx minimums Class B,C,D,E airspace:

Answer 13

• Army helicopter SVFR minimum is 1/2 mile visibility and clear of clouds, unless a higher minimum is required at the airfield.
• Cairns SVFR is 300-1/2 D, 500-1 N

Question 14

Class A Airspace:

Answer 14

• At or above 18,000 feet MSL

- Airspace above 60,000 will convert back to class E

Question 15

Class B Airspace:

Answer 15

• SFC to 10,000 MSL or as depicted. (upside down wedding cake)
• 30 NM Mode C veil.
• ATC clearance, two-way commo, mode C Xponder required.
  
  • If acft is not equipped with Mode C Xponder, the request to operate at an airport requiring transponder must be made at least one hour before entry.

Question 16

Class C Airspace:

Answer 16

• SFC to 4,000 AGL as depicted.
• Two magenta colored circles: 5nm inner circle SFC - 4000 AGL / 10nm outer circle 1200 AGL - 4000 AGL.
• 20nm procedural outer area. 2 way commo required, mode C xponder required in or above class C.
• Must have a 1,000 foot ceiling to operate VFR under a ceiling. If less than that, must request SVFR.

Question 17

Class D Airspace:

Answer 17

• SFC to 2,500 AGL above airport when tower is operational.
• Depicted as one blue dash circle (approx 4-5nm radius) as depicted on map.
• May have Class D or E extensions for instrument approaches.
  
  • If extension is less than 2nm = Class D, if greater than 2nm, Class E
• 2 way commo required prior to entry Class E keyhole if field is IFR.
• Must have 1,000 foot ceiling to operate VFR under ceiling.
• When tower is closed the class D airspace will convert to Class E-SFC or Class G-SFC, consult IFRS to see which.
  
  • Cairns/Dothan both convert to Class E-SFC

Question 18

Class E airspace:

Answer 18

• All controlled Airspace not classified as A,B,C,D.

Question 19

Class G Airspace:

Answer 19

• Is all airspace not classified as A,B,C,D,E. Class G starts at the ground and goes up to the next controlling airspace.
• Class G is considered “uncontrolled airspace.”
• NOTE: Mode C required within Class B veil or when flying above 10,000 MSL.
