Flashcards in Airspace Deck (19):

-Regulatory airspace includes:

-Class A
-Class B
-Class C
-Class D
-Class E


-Non-regulatory airspace includes:

-All other types of airspace such as:
-Class G
-Warning Areas
-Alert Areas


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.
