## What is a NOTAM?

A **Notice to Airmen (NOTAM)** is a notice containing information concerning the establishment, condition, or change in any aeronautical facility, service, procedure, or hazard, the timely knowledge of which is essential to personnel concerned with flight operations.

## NOTAM Series

NOTAMs are issued in series identified by a letter (e.g., A, B, C):
*   **Series A**: General international importance.
*   **Series B**: Matters of national importance.
*   **Series C**: For aerodromes only.

## SNOWTAM and ASHTAM
*   **SNOWTAM**: A special series NOTAM notifying the presence or removal of hazardous conditions due to snow, ice, slush, or standing water on the movement area.
*   **ASHTAM**: A special series NOTAM notifying characteristic change in volcanic activity, volcanic eruption, and/or volcanic ash cloud of operational significance.

## Pre-Flight Information Bulletin (PIB)
During pre-flight preparation, pilots receive a PIB which filters NOTAMs relevant to their flight:
*   **Aerodrome PIB**: NOTAMs for Departure, Destination, and Alternates.
*   **Area PIB**: NOTAMs for FIRs (Flight Information Regions) crossed.
*   **Route PIB**: NOTAMs for a specific route corridor.
*   **Narrow Route PIB**: Only NOTAMs within a narrow path along the route.
