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

  • Flight is prohibited
  • Blue fencing
  • usually small

Restricted Areas

  • Access requires permission, probably

Warning Areas

Military Operating Areas (MOA)

  • Foreflight will show these at glowing red

controlled Firing Areas:

Alert area

  • Includes like practice areas

Additional Airspace

  1. Military Training Routes
    • Routes for low-level high speed trainings
    • With 4 digits - means lower, 3 digits means higher
  2. Temporary flight restrictions (TFR)
    • Can pop up for reasons, are usually timed
    • Includes:
      • where the president goes
      • stadium
      • forest fire
      • Airshows
  3. Terminal Radar Service Area (TRSA)

  4. 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
