What is a Prohibited area?
- Established for security
- Cannot fly through these areas
How is a Prohibited area depicted on an IFR chart?
- Surrounded by Blue hash marks
- Label will start with a ‘P’
What is a restricted area?
- CANNOT enter while active without approval from the controlling agency
- Usually for military activity
How is a Restricted area depicted on an IFR chart?
- Surrounded by Blue hash marks
- Label will start with an ‘R’
How is an Alert Area depicted on an IFR chart?

- Label will start with an ‘A’
**(Not depicted on VFR charts)
What is an Alert area?
- An area with a large amount unusual activity that may be hazardous to unware aircraft
- Usually pilot training
- No restrictions for entering
How is a Warning Area depicted on an IFR chart?
- An area surrounded by Blue Hash marks

- Will be labeled with a ‘W’
What is a Warning Area?
- An area usually off the coast where activity hazardous to non-participating aircraft may exist.
- Usually military activity over the ocean
- No restrictions on entering (but ill advised when active)
How are Military Operations Area (MOA) depicted on an IFR Chart?
- Brown Hash marks
- Will be labeled with “MOA”
What is a MOA?
- Military Operations Area established to separate military training from IFR traffic
- IFR traffic may be cleared through when active
- No specific clearance is required to enter but it is advisable for VFR traffic to avoid when active
What is a TFR?
- Temporary Flight Restriction
- Established for Public figures, sports games, or for other security reasons
- It is usually possible to fly in a TFR provided you have previous ATC approval
**Rules regarding each TFR may be different
What is the ADIZ?
- Air Defense Identification Zone
- Its used for the early identification of aircraft operating near the US
What is required to operate through the ADIZ?
- Mode C XPDR
- Two-Way Radio
- An IFR flight plan or a Defense VFR flight plan with the specific time you are expected to enter the ADIZ
**You must also leave within 5 mins of your estimated departure time
On an Enroute chart, how would you know if an airport has an IAP available?
The circular airport identifier will be BLUE or GREEN.
*The difference between blue and green airport symbols is not relevant to civil aviation
What does a BROWN circular airport identifier mean on an enroute chart?
It does NOT have an IAP available
How can you find airports on an enroute chart?
They will be Blue, Green or Brown circles
What does it mean if a double circle with tick marks symbol is shown on an enroute chart?
It is a dual purpose Military and Civil airport
What does it mean if you see a double circle airport symbol on an enroute chart?
This indicates a Military airport
Is class A airspace depicted on a low altitude enroute chart?
No, because low altitude enroute charts are for use BELOW 18,000ft MSL
