Heavy Traffic Around Military Fields
48.1 Pilots are advised to exercise vigilance when in close proximity to most military airports. These airports may have jet aircraft traffic patterns extending up to 2,500 feet above the surface. In addition, they may have an unusually heavy concentration of jet aircraft operating within a 25.nautical mile radius and from the surface to all altitudes. The precautionary note also applies to the larger civil airports.

ENR 1.4 ATS Airspace Classification
1. General
1.1 There are two categories of airspace or airspace areas:
1.1.1 Regulatory (Class A, B, C, D, and E airspace areas, restricted and prohibited areas).
1.1.2 Nonregulatory (military operations areas (MOAs), warning areas, alert areas, and controlled firing areas).
NOTE.
Additional information on special use airspace (prohibited areas, restricted areas, warning areas, MOAs, alert areas, and controlled firing areas) may be found in Sec-tion ENR 5.1, Prohibited, Restricted and Other Areas, paragraph 1 and Section ENR 5.2, Military Exercise and Training Areas, paragraphs 1. through 3.
1.2 Within these two categories, there are four types:
1.2.1 Controlled.
1.2.2 Uncontrolled.
1.2.3 Special use.
1.2.4 Other airspace.
1.3 The categories and types of airspace are dictated by:
1.3.1 The complexity or density of aircraft move-ments.
1.3.2 The nature of the operations conducted within the airspace.
1.3.3 The level of safety required.
1.3.4 The national and public interest.
1.4 It is important that pilots be familiar with the operational requirements for each of the various types or classes of airspace. Subsequent sections will cover each class in sufficient detail to facilitate understand-ing.
1.5 General Dimensions of Airspace Segments
1.5.1 Refer to Title 14 of the U.S. Code of Federal Regulations (14 CFR) for specific dimensions, exceptions, geographical areas covered, exclusions, specific transponder or equipment requirements, and flight operations.
REFERENCE.
See GEN 1.7, Annex 2, for U.S. Differences From ICAO Standards, Recommended Practices and Procedures.
1.6 Hierarchy of Overlapping Airspace Designa-tions
1.6.1 When overlapping airspace designations apply to the same airspace, the operating rules associated with the more restrictive airspace designation apply.
1.6.2 For the purpose of clarification:
1.6.2.1 Class A airspace is more restrictive than Class B, Class C, Class D, Class E, or Class G airspace.
1.6.2.2 Class B airspace is more restrictive than Class C, Class D, Class E, or Class G airspace.
1.6.2.3 Class C airspace is more restrictive than Class D, Class E, or Class G airspace.
1.6.2.4 Class D airspace is more restrictive than Class E or Class G airspace.
1.6.2.5 Class E is more restrictive than Class G airspace.
1.7 Basic VFR Weather Minimums
1.7.1 No person may operate an aircraft under basic VFR when the flight visibility is less, or at a distance from clouds that is less, than that prescribed for the corresponding altitude and class of airspace. (See TBL ENR 1.4.1.)
NOTE.
Student pilots must comply with 14 CFR Section 61.89(A)
(6) and (7).
1.7.2 Except as provided in 14 CFR Section 91.157, Special VFR Minimums, no person may operate an aircraft beneath the ceiling under VFR within the lateral boundaries of controlled airspace designated to the surface for an airport when the ceiling is less than 1,000 feet. (See 14 CFR Section 91.155(c).)
