Accordingly, what is a Class B airport?
Class B is a class of airspace in the United States which follows International Civil Aviation Organization (ICAO) airspace designation. The airspace around the busiest US airports is classified as ICAO Class B, and the primary airport (one or more) for which this airspace is designated is called Class B airport.
Beside above, how does airport security differ between commercial service airports and general aviation airports? Commercial consists of full TSA security and general aviation consists of a decrease in security and just use the requirements.
In this regard, are there Class G airports?
Like Class E airspace, you can fly through Class G airspace at airports (the "terminal environment") and while en-route. However, Class G airspace isn't controlled. Neither VFR (Visual Flight Rules) nor IFR (Instrument Flight Rules) aircraft need an ATC clearance to operate in Class G airspace.
How many types of airports are there in the world?
There are over 40,000 airports with codes given by the International Civil Aviation Organization (ICAO), a United Nations sponsored group. If you are concerned to count the number of airports that have passenger service in Jets ( more than 50 Passengers) the number would be around 10,000 globally.
