Federal Aviation Administration, DOT 

§ 99.43 

the contiguous U.S. ADIZ unless that 
aircraft is equipped with a coded radar 
beacon transponder and automatic 
pressure altitude reporting equipment 
having altitude reporting capability 
that automatically replies to interro-
gations by transmitting pressure alti-
tude information in 100-foot incre-
ments. 

(d) Paragraphs (b) and (c) of this sec-

tion do not apply to the operation of an 
aircraft which was not originally cer-
tificated with an engine-driven elec-
trical system and which has not subse-
quently been certified with such a sys-
tem installed, a balloon, or a glider.

designated at 69 FR 16756, Mar. 30, 2004] 

§ 99.15

Position reports. 

(a) The pilot of an aircraft operating 

in or penetrating an ADIZ under IFR— 

(1) In controlled airspace, must make 

the position reports required in § 91.183; 
and 

(2) In uncontrolled airspace, must 

make the position reports required in 
this section. 

(b) No pilot may operate an aircraft 

penetrating an ADIZ under DVFR un-
less— 

(1) The pilot reports to an appro-

priate aeronautical facility before pen-
etration: the time, position, and alti-
tude at which the aircraft passed the 
last reporting point before penetration 
and the estimated time of arrival over 
the next appropriate reporting point 
along the flight route; 

(2) If there is no appropriate report-

ing point along the flight route, the 
pilot reports at least 15 minutes before 
penetration: The estimated time, posi-
tion, and altitude at which the pilot 
will penetrate; or 

(3) If the departure airport is within 

an ADIZ or so close to the ADIZ bound-
ary that it prevents the pilot from 
complying with paragraphs (b)(1) or (2) 
of this section, the pilot must report 
immediately after departure: the time 
of departure, the altitude, and the esti-
mated time of arrival over the first re-
porting point along the flight route. 

(c) In addition to any other reports 

as ATC may require, no pilot in com-
mand of a foreign civil aircraft may 
enter the United States through an 
ADIZ unless that pilot makes the re-

ports required in this section or reports 
the position of the aircraft when it is 
not less that one hour and not more 
that 2 hours average direct cruising 
distance from the United States. 

[69 FR 16756, Mar. 30, 2004] 

§ 99.17

Deviation from flight plans and 

ATC clearances and instructions. 

(a) No pilot may deviate from the 

provisions of an ATC clearance or ATC 
instruction except in accordance with 
§ 91.123 of this chapter. 

(b) No pilot may deviate from the 

filed IFR flight plan when operating an 
aircraft in uncontrolled airspace unless 
that pilot notifies an appropriate aero-
nautical facility before deviating. 

(c) No pilot may deviate from the 

filed DVFR flight plan unless that pilot 
notifies an appropriate aeronautical fa-
cility before deviating.

§ 99.41

General. 

The airspace above the areas de-

scribed in this subpart is established as 
an ADIZ. The lines between points de-
scribed in this subpart are great circles 
except that the lines joining adjacent

are rhumb lines.
