• referred to as uncontrolled airspace
• ATC does not provide separation service for IFR flights
• no mandatory communication requirements
• has less strict weather min than controlled airspace
• my be used by pilots with any level of certificate
• starts at the surface and extends upto the base of class E
• is not directly dipicted on sectional charts

Question 2

Class E

Answer 2

• Depicted on charts with the fuzzy side of either a magenta or a blue vignette.
• Dashed magenta lines - beginning at the surface
• Fuzzy side of magenta vignette - beginning at 700 feet AGL
• Fuzzy side of blue vignette - beginning at 12 feet AGL
• Controlled airspace that is not Class A, B, C or D
• Separation service for IFR flights is provided by ATC
• Legal for VFR flights to fly in without talking to anyone
• Least restrictive of controlled airspace
• Established in the 48 states and alaska at and above 14,500 feet MSL unless a lower alt is shown on the chart
• Upper limit of Class E is 17,999 feet MSL and above 60,000 feet again.

Question 3

Class D

Answer 3

• Is depicted with a blue dashed line on charts
• Requires two way communication equipment
• Establish two-way communication prior to entry
• Laterally a circle with a radius of 5 statute miles
• Vertically from the surface to 2,500 feet above airport ele
• To decode, add two zeros after the [-38]. the minus sign in front of the altitude means “up to but not including”
• Arrivals and departures to/from a secondary airport in the Class D must contact the tower at the class D airport.

Question 4

Class C

Answer 4

• Depicted with solid magenta lines on charts
• Laterally 5 nautical miles, vertically upto 4000 ft above the airport elevation.
• A shelf area extends laterally from 5 miles to 10 miles radius
• A shelf area extends vertically from no lower than 1200 feet above airport elevation to 4000 feet.
• Requires two way comm equipment
• ## Having ATC identify you with your call sign

Question 5

Class B

Answer 5

• Depicted with solid blue lines on charts
• Must have two-way communications equipment
• An operable radar beacon transponder with altitude reporting equipment (mode C)
• Extends upto 30 nautical miles from the airport
• From the surface to 10,000 feet MSL vertically

Question 6

Class A

Answer 6

• Not depicted on charts
• Is the most restrictive
• Includes laterally the lower 48 states and Alaska
• Vertically 18,000 feet MSL to 60,000 feet MSL
• requires instrument rated and instrument current pilots
• IFR flight plan, Mode C transponder
