Section 2. Transitional Airspace
Transitional areas, Class E, are designated to serve
terminal and en route aircraft to include helicopter
operations such as:
a. Transitioning to/from terminal and en route.
b. Transiting between airways and routes.
c. En route climbs or descents.
e. Radar vectors.
f. Providing for course changes.
g. When the route under consideration is almost all
within existing Class E airspace and small additions would
complete the coverage.
The only areas that are normally excluded in the Class E
description should be limited to Mexico, Canada, SUA and
international airspace. Exclude SUA only when active. Do not
exclude Federal Airways or other airspace areas.
h. En route training operations.
18-2-2. 700/1,200-FOOT CLASS E AIRSPACE
E-5 700/1200-foot airspace areas are used for transitioning
aircraft to/from the terminal or en route environment.
18-2-3. 700-FOOT CLASS E AIRSPACE
Class E-5 airspace area with a base of 700 feet above the
surface must be designated to accommodate arriving IFR
operations below 1,500 feet above the surface and departing
IFR operations until they reach 1,200 feet above the
18-2-4. 1,200-FOOT CLASS E AIRSPACE
sufficient controlled airspace does not exist, designate a
1,200 foot Class E-5 airspace area to accommodate arriving
IFR operations at 1,500 feet and higher above the surface
and departing IFR operations from the point they reach 1,200
feet above the surface until reaching overlying or adjacent
18-2-5. CLASS E AIRSPACE FLOORS ABOVE 1,200 FEET
E-5 airspace areas may be established with MSL floors above
1,200 feet AGL. Normally floors will be at least 300 feet
below the minimum IFR altitude.
18-2-6. COORDINATION OF MISSED APPROACH ALTITUDES
Coordination must be initiated with the appropriate FPT or
military representatives to adjust missed approach altitudes
upward to at least 1,500 feet above the terrain at locations
where existing procedures specify lower altitudes and such
action can be accomplished without penalty to overall IFR
operations or without exceeding TERPS criteria.
