Airspace Flashcards
What is the difference between agl AND msl?
AGL is above ground level; MSL is mean sea level which is distance above relative sea level
What is the distances of Class A airspace? What is this space also called? – How far out past the coastline does this area go?
From 18,000 - 60,000 MSL; also called “flight level” – extends out 12 NM from coastline
What is Class B airspace? What is the typical ceiling for it? How is it depicted on sectional charts?
For big airports - depicted as a solid blue line on sectional charts – typical ceiling is 10,000 MSL
What is Class C airspace? Describe the typical two rings, their distances – do we use AGL or MSL to describe them?
Usually for smaller than Class B airports – two rings: Surface area and Shelf area – Center ring (surface area) is from surface to 4,000 feet AGL and has a diameter of 5 NM — Outer ring (shelf area) is from 1,200 AGL to 4,000 AGL and has a radius of 10NM
How is Class C airspace depicted on a sectional chart?
with a solid magenta line
What is Class D airspace? How many rings does it have? Describe the distances used for this airspace.
For smaller airports than B or C; usually with one control tower – one ring around it that extends up to 2,500 feet AGL above the airport
For Class A, B, C, D airspace, do you need to have prior authorization?
Yes - you need to establish communication with the tower before entering the airspace
How is Class D airspace depicted on a sectional chart? What is the ceiling of Class D airspace depicted as on a sectional chart?
a blue dashed line – a blue dashed box indicated class D ceiling in hundreds of feet – ex:40 in a dashed blue box is 4,000 feet
There are two types of Class E airspace: surrounding airports and then everywhere else – describe the distances for both
Surrounding airspace: starts at 700 feet AGL or the surface — In other areas not marked with Class B,C,D, Class E airspace starts at 1,200 feet AGL and goes up to but not including 18,000 MSL
How is Class E airspace depicted on a sectional chart? Note the two types
Dashed or shaded magenta line – Dashed magenta line indicates that the floor of Class E is the surface – Shaded magenta line indicatees that the floor of Class E is 700 feet AGL
How far does Class E airspace extend out around an airport?
10 NM
Do you need prior authorization to go in Class E airspace?
Yes, only if near an airport
What is Class G airspace? What does it also include?
Free zone that is unmonitored by the FAA – it does also include Class E airspace though from 1,200 AGL to (but not including) 18,000 MSL – no prior authorization is needed to fly here
What is Special Use Airspace?
where activities must be contained (i.e. warning, restricted areas, military operations, CFA (controlled firing areas) etc.
What are Prohibited Areas? How are they depicted on a sectional chart?
where flying is not allowed – I.e. White House – they are marked by a “P” on a sectional chart
