2.

Intended for operations down to an RVR of

the order of 50 m (no decision height being

applicable) using visual aids for taxiing;

3.

Intended for operations without reliance on

visual reference for landing or taxiing.

Note 1: See Annex 10 Volume I, Part I, Chapter 3,

for related ILS specifications.

Note 

2: Visual aids need not necessarily be

matched to the scale of nonvisual aids provided.
The criterion for the selection of visual aids is the
conditions in which operations are intended to be
conducted.

INTEGRITY− The ability of a system to provide

timely warnings to users when the system should not

be used for navigation.

INTERMEDIATE APPROACH SEGMENT−

(See SEGMENTS OF AN INSTRUMENT

APPROACH PROCEDURE.)

INTERMEDIATE APPROACH SEGMENT

[ICAO]− That segment of an instrument approach

procedure between either the intermediate approach

fix and the final approach fix or point, or between the

end of a reversal, race track or dead reckoning track

procedure and the final approach fix or point, as

appropriate.

INTERMEDIATE FIX− The fix that identifies the

beginning of the intermediate approach segment of an

instrument approach procedure. The fix is not

normally identified on the instrument approach chart

as an intermediate fix (IF).

(See SEGMENTS OF AN INSTRUMENT

APPROACH PROCEDURE.)

INTERMEDIATE LANDING− On the rare occasion

that this option is requested, it should be approved.

The departure center, however, must advise the

ATCSCC so that the appropriate delay is carried over

and assigned at the intermediate airport. An

intermediate landing airport within the arrival center

will not be accepted without coordination with and

the approval of the ATCSCC.

INTERNATIONAL AIRPORT− Relating to interna-

tional flight, it means:

a.

An airport of entry which has been designated

by the Secretary of Treasury or Commissioner of

Customs as an international airport for customs

service.

b.

A landing rights airport at which specific

permission to land must be obtained from customs

authorities in advance of contemplated use.

c.

Airports designated under the Convention on

International Civil Aviation as an airport for use by

international commercial air transport and/or interna-

tional general aviation.

(See ICAO term INTERNATIONAL AIRPORT.)

INTERNATIONAL AIRPORT [ICAO]− Any airport

designated by the Contracting State in whose

territory it is situated as an airport of entry and

departure for international air traffic, where the

formalities incident to customs, immigration, public

health, animal and plant quarantine and similar

procedures are carried out.
INTERNATIONAL CIVIL AVIATION ORGA-

NIZATION [ICAO]− A specialized agency of the

principles and techniques of international air

navigation and to foster planning and development of

international civil air transport.

INTERNATIONAL FLIGHT INFORMATION

MANUAL− A publication designed primarily as a

pilot’s preflight planning guide for flights into

foreign airspace and for flights returning to the U.S.

from foreign locations.
INTERROGATOR− The ground-based surveillance

radar beacon transmitter-receiver, which normally

scans in synchronism with a primary radar,

transmitting discrete radio signals which repetitious-

ly request all transponders on the mode being used to

reply. The replies received are mixed with the

primary radar returns and displayed on the same plan

position indicator (radar scope). Also, applied to the

airborne element of the TACAN/DME system.
