TITLE 14 CIVIL AVIATIO N
Chapter I Civil Aeronautics Board Subchapter A Civil Air Regulation
Supp. 2, Arndt. 1
P art 60Air T raffic R ules MINIMUM ENROUTE INSTRUMENT ALTITUDES

Under section 205 a of the Civil Aeronautics Act of 1938, as amended, the Administrator of Civil Aeronautics is "authorized to make and amend such rules, regulations, and procedure as are necessary to carry out the provisions of, and to perform and exercise his powers and duties under, the act. Under section 601 of the Civil Aeronautics Act of 1938, as amended, the Civil Aeronautics Board is empowered to delegate to the Admin istrator of Civil Aeronautics the author ity to prescribe rules, regulations, and standards which promote safety of flight in air commerce. Under 60.17 d of the Civil Air Regulations, the Civil Aero nautics Board has provided that, except when necessary for taking off or land ing, no person shall operate an aircraft in accordance with IFR below the mini mum IFR altitudes established by the Administrator for that portion of the route over which the operation is conducted.
Acting pursuant to the foregoing au thority, minimum enroute instrument altitudes were published as rules. Those rules are amended herewith.
This amendment is made effective January 30, 1950. Compliance with the notice, procedures, and effective date provisions of section 4 of the Administrative Pro cedure Act would be impracticable and contrary to the public interest, and therefore is not required.
Sections 60.17-3 through 60.17-1004
are amended to read:
60.17-3 Minimum en route instru ment altitudes along particular routes CAA rules which apply to 60.17 d
a En route procedure1 Climb.
Climb to a higher IFR altitude minimum shall begin immediately after passing the point beyond which the higher minimum applies except that when the rules in this part indicate that ground obstructions intervene, the point beyond which the higher minimum applies shall be crossed at the .minimum crossing altitude speci
fied in this part unless an air traffic clearance authorizes the use of a higher altitude. Points where ground obstruc tions intervene will be denoted by an as terisk followed by the minimum crossing altitudes specified for the associated fix.
