Depending upon the crew, level of expertise and flight department SOPs, different requirements may be considered in terms of ceilings. In some cases, the crew may specify a minimum ceiling height, perhaps 3,000 ft, while in other cases they may require higher minimum ceiling heights.
Ceiling at your intended destination may be defined as the lowest broken or overcast cloud layer. If the sky is totally obscured, height of vertical visibility is used as the ceiling. Your forecaster will provide insights regarding expected changes to ceilings, as well as other weather events such as fog is expected to move in/out of your destinati...
Different types of cloud cover conditions include SKC (sky clear), FEW (trace), SCT (scattered), BKN (broken) and OVC (overcast). Cloud cover is reported in terms of 1/8th of sky cover with 1-2/8th being FEW, 3-4/8ths being SCT, 5-7/8th being BKN and 8/8 denoted at OVC. Automated Weather Observing Systems (AWOS) at larger airports routinely measure...
Part 135 charter (non-scheduled commercial) operators must, by regulatory requirement, use official government weather forecasts and not forecasts provided by any weather provider. This may affect the charter operator’s ability to operate to certain locations, or require a flight diversion, even though actual weather may differ from an official for...
To make accurate determinations of ceiling height, your weather provider will first use weather forecasts and then other tools including satellite imagery, Pilot (weather) Reports (PIREPs) and local observations. Airport Meteorological Aerodrome Reports (METARs) provide current conditions while Terminal aerodrome forecasts (TAFs) indicate forecast ...
When considering minimum ceiling requirements for destination airports, one must also consider available airport alternates. When operating to parts of China, Russia or Canada you may have few nearby alternate options, and this may mean specifying a higher minimum ceiling requirement for your destination airport. Additionally, equal time points (ET...
When operating to remote locations there may be limited TAFs, METARs, PIREPs and local weather data available. Your weather provider may need to estimate ceiling height based on weather models, satellite imagery, local terrain conditions and weather data from surrounding locations. Airport location, elevation, mountainous terrain, moisture levels a...
In some regions, and at certain times of year, ceiling heights may be habitually below minimums. Some locations in India, for example, may be under IFR conditions most of the year due to smoke and haze issues. The same is true in parts of China during the rice field burning season.
As weather conditions change rapidly, forecasts are most accurate when obtained no more than two to three days prior to operation. In determining predicted ceiling height it’s always best to rely on forecasts obtained within 24 hours of flight. The region you’re operating to is also a factor, as low ceiling conditions may be more likely during part...
Depending on the type of flight, company SOPs, captain experience, and surrounding alternates, operators have differing requirements for ceilings for each destination. Always contact a certified meteorologist for the most accurate prediction of weather and ceilings for your trip. There are many factors that are used in predicting ceilings so it’s i...
Meteorologists convey the chance of cloud cover or rain in percentages, but what those numbers mean in the real world isn’t always clear, so you’ll often hear terms like scattered and isolated...
Jul 5, 2016 · The NWS definition states that between 3/8 and 5/8 of the sky is covered by clouds when it's classified as partly cloudy or partly sunny. Sometimes, a...
"Scattered" clouds (3/8 to 4/8 cloud coverage) correspond to a partly cloudy or partly sunny sky, with "broken" clouds (5/8 to 7/8 cloud coverage) describing a partly cloudy or partly sunny (5/8 coverage) to mostly cloudy (6/8 to 7/8 coverage) sky.
Feb 5, 2019 · “Scattered or isolated thunderstorms” describe the expected extent of thunderstorm activity. Unlike organized storm fronts, isolated and scattered storms affect a far smaller area so not everyone will experience them.
Sep 2, 2023 · The key difference between isolated and scattered thunderstorms is the coverage area. Isolated thunderstorms occur over a limited area, usually around 10 miles in diameter, while scattered thunderstorms cover much larger areas with multiple storms occurring across the region.
