ter cannot be conducted consistent 
with the required levels of safety and 
efficiency— 

(1) The Administrator issues an im-

mediately effective air traffic rule or 
regulation in response to that emer-
gency condition; and 

(2) The Administrator or the Asso-

ciate Administrator for Air Traffic 
may utilize the NOTAM system to pro-
vide notification of the issuance of the

tions that govern flight operations, the 
use of navigation facilities, and des-
ignation of that airspace in which the 
rules and regulations apply. 

(c) When a NOTAM has been issued 

under this section, no person may oper-
ate an aircraft, or other device gov-
erned by the regulation concerned, 
within the designated airspace except 
in accordance with the authorizations, 
terms, and conditions prescribed in the 
regulation covered by the NOTAM.

ures contrary to the restrictions estab-
lished by the Administrator and pub-
lished in a Notice to Airmen (NOTAM). 

§ 91.143

Flight limitation in the prox-

imity of space flight operations. 

When a Notice to Airmen (NOTAM) is

Temporary restriction on 

flight operations during abnormally

(a) 

Special flight restrictions. When any

of mercury, no person may operate an 
aircraft or initiate a flight contrary to 
the requirements established by the 
Administrator and published in a No-
tice to Airmen issued under this sec-
tion. 

(b) 

Waivers.  The Administrator is au-

thorized to waive any restriction

livered to isolated communities, where 
the operation can be conducted with an 
acceptable level of safety.
