Airspace Flashcards
-Regulatory airspace includes:
- Class A
- Class B
- Class C
- Class D
- Class E
- Prohibited
- Restricted
-Non-regulatory airspace includes:
- All other types of airspace such as:
- Class G
- MOA’s
- Warning Areas
- Alert Areas
- CFA’s
What are the four types of airspace?
- Controlled (includes A,B,C,D,E)
- Uncontrolled (class G only)
- Special use (see spec use airspace)
- Other airspace (see other use airspace)
What are the two general categories of airspace?
Regulatory and non-regulatory
Mode C transponder is required when operating: (FAA requirement - Army considers it minimum equipment)
- Within all class A airspace
- Within 30 NM of Class B Airports
- Within or above all Class C Airports
- At or above 10,000 ft MSL
- Operations within, across, or into ADIZ
Transponder operations (special codes)
- 1200 - VFR flight
- 4000 - Military restricted/warning area
- 7777 - Military interceptor operations
- 7500 - hijack
- 7600 - Lost Commo
- 7700 - Emergency
Army VFR Wx minimums:
-Class B
- 3 SM visibility
- clear of clouds
Army VFR Wx minimums:
-Class C
- 3 SM visibility
- 500 ft below, 1000 ft above, 2000 ft horiz
Army VFR Wx Minimums:
-Class D
- 3 SM visibility
- 500 ft below, 1000 above, 2000 horiz
Army VFR Wx minimums:
-Class E
- Class E above 10,000 MSL- 5 SM vis/ 1000 ft below, 1000 ft above, 1sm horiz
- Class E below 10,000 MSL - 3 SM vis/ 500 below, 1000 above, 2000 horiz
Army VFR Wx Minimums:
-Class G above 1200 AGL
- Above 10,000 MSL - 5 SM vis/ 1000 below, 1000 above, 1 SM horiz
- Below 10,000 MSL - 1/2 sm vis (day)/1 sm (night) and clear of clouds
Army VFR Wx Minimums:
-Class G below 1200 AGL
- 1/2 sm vis (day) 1 sm vis (night)
- Clear of clouds
SVFR Wx minimums Class B,C,D,E airspace:
- 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
Class A Airspace:
- At or above 18,000 feet MSL
- Airspace above 60,000 will convert back to class E
Class B Airspace:
- 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.
Class C Airspace:
- 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.
Class D Airspace:
- 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
Class E airspace:
- All controlled Airspace not classified as A,B,C,D.
- Types of Class E airspace:
- Domestic areas where fed airway system is inadequate, Unless designated 14,500 MSL, SFC AREA FOR AN AIRPORT, Federal airways, Class B,C,D extensions, Offshore areas, Airport transitions.
Class G Airspace:
- 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.
