Airspace and Sectional Charts
Dimensions, Restrictions, and weather restrictions
ADSB - flight tracking
Work with your instructor to have your own personal minimums
Class A
High altitude PPL cannot enter class A FAA wants to reset altimiter every 100mi, flight follow will give you one every 25mi Must be IFR
Class B
Upside down tirred cake, but not always a circle. Seattle is a trapezoid only 25 in all of the country Only the busiest of busiest airports
250kts inside 200kts limits outside
mode c veil requires ADSB Mode c transponder (within 30nm, up to 10,000ft MSL) Mode C: altitude reporting
ATC clearance required to enter
Most have landing fees
Mode C
Tiers are variable based on airport 1 - 0-1100 2.
Most B airports don't allow student pilots You need a spec
Clearance is only for
Class C
Busy airports, big airports, but now busy enough to be a B
Always circular
Two layers
Still need ADSB, still need transponder Need 2 way radio
If you
Tower only cares about
Trachon is spreading the work across the different controllers Approach controllers Tower controllers Ground controllers
Weather: 152
Class D
7S3 is 170 MSL
2500 AGL 4NM
Two way radio Contact ATC before entering Maintain contact with ATC Max speed of 200kts inside the airspace
Weather minimums 3152
Class E
Everything else - but a layer Sometimes the floor cuts through echo
Starts at 1200 agl
To be VFR, you must be 3152: 3 miles of visibility 1000 above clouds 500 below clounds 2000 horizontal from clouds
If you're above 10,000ft MSL, 5111 5 1 1 1 mile horizontal
above 10000, you need adsb and mode c transponder
Class G
Below E
1 SM visibility clear of clouds (as close as you can get)
at night it's 3152
It's more restrictive because usually the traffic moves a lot faster
Portland metro area has class 3 starting at 700 AGL
Restrictions No communication requirement No instrument requirements
Special use airspace
Prohibited Areas

- Foreflight will show these at glowing red
controlled Firing Areas:
Alert area
- Includes like practice areas
Additional Airspace
- Military Training Routes
- Routes for low-level high speed trainings
- With 4 digits - means lower, 3 digits means higher
- Temporary flight restrictions (TFR)
- Can pop up for reasons, are usually timed

- where the president goes
- stadium
- forest fire
- Airshows
-
Terminal Radar Service Area (TRSA)
- National Security Areas
Special VFR
Allows you to fly close to clouds in worse weather than normal VFR
You have to ask for it
You can get SVFR for B-E airspace, but some airspace doesn't allow it at all. i.e. PDX
Sectional Markings
Magenta is uncontrolled Blue is controlled
--
When you try to turn a comm radio below 118 it circles around. Anything below 118 is a navigation frequency
A flight service station is for information. You can
Blue line with dots is a wildlife refuge They want you flying 2000AGL over there to avoid disturbing the wildlife
