DEFINITION AND INTRODUCTION OF NOTAM

Definition of NOTAM

A NOTAM (Notification to Airmen) is a notice distributed by means of telecommunications containing information concerning the establishment, conditions or change in any aeronautical facility, service, procedure or hazard, the timely knowledge of which is essential to personnel concerned with flight operations.

Purpose of NOTAM Distribution

The basic purpose of NOTAM is the distribution of information that may affect safety and operations in advance of the event to which it relates, except in the case of unserviceable facilities or unavailability of services; volcanic activity; release of radioactive material and toxic chemicals that cannot be foreseen.

Thus, to realize its purpose the addressee must receive a NOTAM in sufficient time to take any required action. (The value of a NOTAM lies in its “news content” and its residual historical value is therefore minimal.)

Introduction

In order to enhance safety during an incident or project, the FAA may be requested to issue a Notification to Airmen (NOTAM) to pilots; these could be either a Temporary Flight Restriction (TFR) or a NOTAM (L) or NOTAM (D). In addition to the NOTAM process, agency personnel contact military facilities and or other agency aviation units to request deconfliction of the involved airspace.

Deconfliction is a process that involves the separation of land management agency and other types of aircraft that may pose a flight hazard. This process is frequently used by local dispatch to inform military units of activity whether emergency or planned. This deconfliction is negotiable unless a TFR is involved. Local dispatch may also use deconfliction information to notify other agency aircraft of an evolving situation that requires deconfliction for safety. See Chapter 7 for additional Airspace Deconfliction information.

A TFR applies to an area of airspace (defined both laterally and vertically) that has been temporarily or partially closed to non-participatory aircraft for a specified period of time. Flight restrictions may be requested in response to the aviation safety need for separation of aircraft for disaster or incident activities.

This chapter describes the types of conditions under which the FAA may impose temporary flight restrictions. It also explains the FAA authority to issue a TFR NOTAM and lists the types of responsible agencies/offices from which the FAA will accept requests to establish TFRs.

The Code of Federal Regulations (14 CFR) is explicit as to what operations are prohibited, restricted or allowed in a temporary flight restriction area. Pilots are responsible to comply with 14 CFR sections 91.137, 91.138, 91.141, 91.143, 91.144, 91.145 and 99.7 when conducting a flight in an area where a TFR is in effect, and should check appropriate NOTAMs during flight planning.
