Definition
Self briefing is the practice of using printed or online data to become familiar with current and forecast weather conditions relevant to a flight. When done correctly, this process helps pilots make informed decisions during the flight. It aids in selecting altitudes, choosing alternate airports, calculating fuel needs, and ensuring compliance with regulations.
Historical Perspective
Before the internet became widely available, most international and regional airports had dedicated weather service offices. These were often located with Airport Operations or within Flight Service Stations (FSS), staffed by professional observers and meteorologists. Pilots from military, corporate, and general aviation backgrounds would regularly visit these offices for weather briefings. Airlines also provided their pilots with weather updates from dispatchers before flights. However, as technology advanced and budgets tightened, many of these services were consolidated into regional offices. Today, pilots can obtain weather information through phone calls or online sources, leading to an increase in self-briefing practices. While self briefing can ensure safety, it requires proper execution to avoid misunderstandings of potential weather impacts.
Challenges
Weather influences every phase of flight, making it crucial for pilots to have a clear understanding of existing and forecast conditions. Many accidents, especially in General Aviation (GA) VFR flights, have been attributed to a lack of weather awareness. Several challenges can hinder effective self-briefing:
-
Time: Historically, preflight planning took 90 minutes to two hours, involving multiple crew members. Now, with two-pilot crews, preparation time has shrunk to around 30 to 60 minutes. This often results in only one pilot reviewing the weather while the other handles different preflight tasks.
-
Scope: Some weather services provide summaries, highlighting significant weather risks, while others inundate pilots with excessive information, making it tough to find relevant data. Many pilots only check weather for departure and destination airports, neglecting en route conditions and hazards.
-
Interpretation: Many pilots lack formal training in interpreting weather data, particularly in general aviation.
-
Complacency: Pilots flying familiar routes may become complacent, believing that weather rarely changes.
-
Corporate Pressures: Business aviation pressures can lead to rushed preparations, skipping thorough self-briefings to expedite departures.
Solutions
To combat complacency and enhance briefing quality, pilots should prioritize a comprehensive understanding of en route and terminal weather for informed decision-making. Here are some strategies to tackle the identified challenges:
-
Time: Preflight time is limited, so it’s essential to organize and prioritize tasks. Conducting an initial weather review 12 to 24 hours before a flight can help identify potential conditions and streamline preparations.
-
Scope: Choose a weather service that customizes reports for your flight and aircraft type, providing concise summaries along with necessary details.
-
Interpretation: Familiarize yourself with relevant meteorological information, including charts and forecasts like TAFs and METARs. Training courses, both online and in-person, are available to enhance interpretation skills.
-
Complacency: Recognize that weather impacts all flight phases, prompting a thorough self-briefing for every flight, regardless of its length.
-
Corporate Pressures: If duty day limits allow, plan to complete preflight tasks well before departure. If passengers arrive early, manage their boarding without compromising the briefing process.
Briefing Methodology
Most training agencies recommend a “top down” approach to weather self-briefing, starting with a broad overview and narrowing down to specific conditions. Here’s a suggested sequence:
-
Review large-scale charts like Surface Analysis and AIRMET/SIGMET maps for a high-level view of weather systems.
-
Examine prognostic charts such as Convective, Icing, and Turbulence Forecasts while maintaining the large-scale perspective.
-
Look at en route winds and temperatures using Winds Aloft forecasts, favoring graphical formats for altitude selection.
-
Finally, check applicable TAFs for departure, destination, and alternate airports.
-
After assessing forecasts, review current conditions with satellite and radar imagery, then analyze PIREPs.
-
Conclude by comparing actual conditions with forecasts to evaluate their accuracy and detect any rapid changes.
Summary
A solid understanding of weather is vital for flight safety. While self-briefing allows crews to familiarize themselves with weather data, it requires the ability to interpret various products effectively. A systematic and thorough weather review can significantly enhance flight safety.
