ICC  IAPS Card Cage 
ICD  (1) Installation Control Drawing 
(2) Interface Control Drawing 
(3) Interactive Design Center 
ICNIA  Integrated Communications,Navigation and 
Identification Avionics 
ICU  Instrument Comparator Unit 
IDC  Indicator Display/Control 
Ident  The action of the transponder transmitting an extra 
pulse along with its identification code (at the 
request of a controller). 
IDG  Integrated Drive Generator 
IDS  (1) Ice Detection System 
(2) Integrated Display System 
IEC  IAPS Environmental Control Module 
IED  Insertion Extraction Device 
IEEE  Institute of Electrical and Electronic Engineers 
IF (if)  Intermediate Frequency. A frequency to which a sig-
nal is shifted as an in-between step in the reception 
or transmission of a signal. 
IFALPA  International Federation of Airline Pilots Association 
IFATCA  International Federation of Air Traffic Controllers. 
Associations 
IFPS  Integrated Initial Flight Plan Processing System 

IFR  Instrument Flight Rules
IGES  Standardized Graphics Exchange File
IGV  Inlet Guide Vane
ILM  Independent Landing Monitor
ILS  Instrument Landing System. The system provides lat-
eral,along-course and vertical guidance to aircraft attempting a landing.
IMA  Integrated Modular Avionics
IMC Instrument Meteorological Conditions IMPATT Impact Avalanche and Transmit Time. This type of Diode diode,when mounted in an appropriate cavity, pro
duces microwave oscillations and amplification. IMTEG ICAO ILS/MLS Transition Group Europe IND Indicator INU Inertial Navigation Unit IAS Indicated Airspeed is the speed indicated by a differ-
ential pressure airspeed indicator which measures the
actual pressure differential in the pitot-static head. It
is the actual instrument indication for a given flight
condition.
Indicated  The altitude above mean sea level (uncorrected for
Altitude  temperature).
INMARSAT  International Maritime Satellite Organization
I/O  Input/Output. Refers to bi-directional data ports.
INPH  Interphone
INS  Inertial Navigation System. A self-contained,dead-reckoning system that senses the acceleration along the three axes of the aircraft and calculates the dis-tance traveled from a reference point. Accuracy of the system decreases with respect to time.
INST  Instrument
Intruder  An altitude reporting aircraft that is being considered as a potential threat and that is being processed by the threat detection logic (TCAS).
IOC  Initial Operational Capability
