Airspace: Entry Requirements
Objectives
Understand the entry requirements for each class of airspace.
Motivations
Timings
45 minutes
Format
- Whiteboard / EFB
Elements
- Class A airspace
- Instrument rating
- IFR flight plan
- IFR clearance
- Separation services provided
- Class B airspace
- IFR flight plan and clearance
- Explicit ATC clearance
- "N549SR cleared in the Class B, maintain 3000"
- Separation services provided
- ADS-B Out + Mode C transponder required within the Mode C veil
- Sectional: KSEA mode C veil
- Class C airspace
- Have their own approach/departure control
- Two-way radio communication required for entry
- Reference your aircraft by your callsign
- "N549SR, Portland Tower." - sufficient
- "Aircraft calling, standby" - not sufficient for entry
- Separation provided between VFR and IFR traffic (not VFR/VFR)
- ADS-B Out + Mode C transponder required within and above the airspace
- Class D airspace
- Two-way radio required for entry:
- Same callsign requirements as Clasc C
- Separation and sequencing provided for VFR traffic
- No ADS-B Out + Mode C transponder required
- Some ATCTs are part-time
- When the tower is closed the airspace reverts to Class E or Class G (chart supplement will say "Other times Class G")
- Two-way radio required for entry:
- Class E airspace
- No entry requirements for VFR
- No separation services for VFR traffic
- Can receive ATC services (IFR, VFR flight following)
- Need ADS-B and Mode C transponder above 10,000' MSL
- Knowledge check
- Flying into Portland Class C airspace, what do we need?
- Flying into Seattle Class B airspace, what do we need?
- Flying at 16,000' VFR and we need to climb due to weather, what should we be aware of?
