§ 121.659

Initial approach altitude: Do-

mestic and supplemental oper-
ations. 

(a) Except as provided in paragraph 

(b) of this section, when making an ini-
tial approach to a radio navigation fa-
cility under IFR, no person may de-
scend an aircraft below the pertinent 
minimum altitude for initial approach 
(as specified in the instrument ap-
proach procedure for that facility) 
until his arrival over that facility has 
been definitely established. 

(b) When making an initial approach 

on a flight being conducted under 
§ 121.657(d), no pilot may commence an 
instrument approach until his arrival 
over the radio facility has definitely 
been established. In making an instru-
ment approach under these cir-
cumstances no person may descend an 
aircraft lower than 1,000 feet above the 
top of the lower cloud or the minimum 
altitude determined by the Adminis-
trator for that part of the IFR ap-
proach, whichever is lower. 

§ 121.661

Initial approach altitude: 

Flag operations. 

When making an initial approach to 

a radio navigation facility under IFR, 
no person may descend below the perti-
nent minimum altitude for initial ap-
proach (as specified in the instrument 
approach procedure for that facility) 
until his arrival over that facility has 
been definitely established. 

§ 121.663

Responsibility for dispatch 

release: Domestic and flag oper-
ations. 

Each certificate holder conducting 

domestic or flag operations shall pre-
pare a dispatch release for each flight 
between specified points, based on in-
formation furnished by an authorized 
aircraft dispatcher. The pilot in com-
mand and an authorized aircraft dis-
patcher shall sign the release only if 
they both believe that the flight can be 
made with safety. The aircraft dis-
patcher may delegate authority to sign 

a release for a particular flight, but he 
may not delegate his authority to dis-
patch. 

[Doc. No. 28154, 61 FR 2615, Jan. 26, 1996] 

§ 121.665

Load manifest. 

Each certificate holder is responsible 

for the preparation and accuracy of a 
load manifest form before each takeoff. 
The form must be prepared and signed 
for each flight by employees of the cer-
tificate holder who have the duty of su-
pervising the loading of aircraft and 
preparing the load manifest forms or 
by other qualified persons authorized 
by the certificate holder. 

§ 121.667

Flight plan: VFR and IFR: 

Supplemental operations. 

(a) No person may take off an air-

craft unless the pilot in command has 
filed a flight plan, containing the ap-
propriate information required by part 
91, with the nearest FAA communica-
tion station or appropriate military 
station or, when operating outside the 
United States, with other appropriate 
authority. However, if communications 
facilities are not readily available, the 
pilot in command shall file the flight 
plan as soon as practicable after the 
aircraft is airborne. A flight plan must 
continue in effect for all parts of the 
flight. 

(b) When flights are operated into 

military airports, the arrival or com-
pletion notice required by §§ 91.153 and 
91.169 may be filed with the appropriate 
airport control tower or aeronautical 
communication facility used for that 
airport.
