Section 2. Transitional Airspace
18-2-1. PURPOSE
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.
d. Holding.
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.
NOTE-
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
Class 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
A Class E-5 airspace area with a base of 700 feet
above the surface shall 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
surface.
18-2-4. 1,200-FOOT CLASS E AIRSPACE
Where 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
controlled airspace.
18-2-5. CLASS E AIRSPACE FLOORS
ABOVE 1,200 FEET
Class 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 shall be initiated with the appropriate
FPO 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.
