CHAPTER ONE

30. HAVE NUMBERS - Used by aircrew to inform ATC that they have received runway,

wind, and altimeter information only.

31. HOW DO YOU HEAR or HOW DO YOU READ - A question relating to the quality of

the transmission or to determine how well the transmission is being received.

Example

CENTER:

"BUCK 717, how do you read this transmitter?"

SNFO/SWSO:

"BUCK 717, loud and clear", or "BUCK 717

weak and unreadable", or "BUCK 717, broken."

32. IDENT - A request for a pilot to activate the aircraft transponder identification feature.

This will help the controller to confirm an aircraft identity. (No verbal response necessary.)

"KATT 811, ident."

CONTROLLER:

33. IFR - Instrument Flight Rules - Rules governing the procedures conducting instrument

flight.

34. IMC - In Instrument Meteorological Conditions, meaning no discernible horizon and/or in

clouds.

Example

"KATT 811, say visibility."

"KATT 811, IMC."

SNFO/SWSO:

IMMEDIATE/IMMEDIATELY - Used by ATC when such action is required to avoid an

imminent situation.

Example

"KATT 833, immediate right turn, heading 180."

CONTROLLER:

SNFO/SWSO:

"KATT 833, right 180."

36. INOPERATIVE - Used to describe a piece of equipment which has ceased to function

properly (e.g., an inoperative TACAN). (Not listed in the pilot/controller glossary, but
