How do Pilots Check the Weather Before Flying?
How Do Pilots Check the Weather Before Flying?
An old aviation aphorism states that there are old pilots and bold pilots, but no old, bold pilots. Going flying without first checking the weather would be sort of like gambling in a casino but with no way to win and many ways to lose. So it is universally recognized by all pilots that one of the keys to a long and prosperous aviation career involves thoroughly checking the weather before committing aviation.
The methods which pilots have used over the years to investigate the weather along their route and at their destination have been continually updated over the years through advances in technology. The Weather Bureau, a predecessor to the National Weather Service, first established an aerological department in 1914 to meet the growing needs of aviation.
Since that time, government provided weather services have been the backbone of aviation weather but that is changing. With the coming of the internet, aviation weather became more democratized and the advent of wireless connectivity means it has never been easier to have access to high quality weather information and graphics wherever a signal is available.
There are many products currently available for pilots to use as a source for weather information but one I've been using has been a standout. Honeywell's Forge Weather Information Service (WIS) is a fully functioned product for presenting a range of weather observations and forecasts to include high quality graphics for pilots. The app is available for both Windows and iOS, but I've been using it on an iPad. It is available from the Apple app store and installed easily.
The first thing I noticed about this app is that it's fast. I mean really fast. I have used many other weather apps and it seems that waiting for a radar picture to load can take forever. That is not the case with WIS. Hit the weather uplink button and your weather data is displayed within less than a second. I realize that this time will vary depending on the speed of your underlying data connection, but the uplink was fast in comparison to other products I've used with the same connection.
The data that you get is everything you need to safely plan and fly your trip. Multiple overlays are available on the map display to show as much or as little data as you care to see. Again, toggling overlays on or off is nearly instantaneous with no discernible lag to render graphics. Did I mention that the software is fast?
The available map overlays include terrain, airports, navaids, waypoints, political boundaries. Most of these are user selectable to provide information when needed or to de-clutter the display when not needed. Another feature of the app that I have really come to appreciate is an automatic map de-clutter feature that displays information based on zoom level.
You would think that such a feature would be standard on most software to be used while performing an intensive task such as flying but that is sadly not the case. Fumbling through menus to de-clutter a map when you might be trying to avoid a storm is not an optimal use of cognitive resources. The engineers at Honeywell have figured this out, and data such as waypoints, navaids, and airports will automatically change presentation based upon the zoom level. Again, this was quite fast with no lag time for rendering. I found this feature quite useful and it made the software a pleasure to use.
You're In Control
When flying in challenging weather, knowing what has happened in the past can be just as important as knowing what the current conditions and forecasts are. Honeywell has included an intuitive time slider on the map display which allows pilots to easily see conditions up to three hours old. Historical data can be displayed as an animation or statically.
And just as the observations time slider allows a look at past conditions, the app also includes a future time slider to display forecasts up to 24 hours ahead of the current time.
The program presents radar, satellite, and lightning date along with available PIREPS in an easily readable and selectable map format. Clicking on any observation or forecast feature will display a window showing the details of that particular area. All of these features worked together to make the product easy to use while flying.
In addition to knowing the "when" of the current and forecast weather, a Flight Level selector lets you control the "where". Moving this selector will present the turbulence (CAT), winds and icing forecasts for your chosen flight level. Satellite observation is also selectable using this slider. This again reinforces the philosophy of only seeing that information which is of use while not cluttering up the display with extraneous data.
Another powerful tool which I found to be very useful is the Vertical Situation Display (VSD). Showing a vertical slice or profile view of weather along the loaded flight plan, it is easy to determine where icing, turbulence and CB tops lie along your route. These things can be determined without the display, but seeing a graphical display is immensely helpful when planning a route. Again, the Honeywell engineers seem to have really put some thought into how this product will be used.
Flight Plans Made Easy
And speaking of flight plans, WIS makes loading and editing flight plans a snap. Flight plans can be loaded from Honeywell's Forge Services, pasted from the clipboard or entered directly. Once loaded, plans are easily edited. It is important to note that the program accepts routing in standard ICAO terms, so don't forget to add "DCT" when proceeding directly between fixes. Plans are then rendered as an overlay on the map display.
The program even has an “own ship” centering feature which can access the GPS signal from the device on which it is installed. Tracking your own progress has never been easier.
A related airports list adds easily accessible weather information from selected airports to a side panel. The best part of this feature is that when refreshed, only data for selected airports will be uplinked, thereby saving data costs.
If you are interested in seeing the weather at any one particular airport, just clicking on the airport symbol on the map brings up a window in which the current METAR, ATIS, and TAF can be instantly displayed. This was probably my favorite feature saving me multiple steps in obtaining this information from several separate sources. It's all conveniently aggregated into one place.
We are living in a golden age of weather information which is available for pilots to plan and fly. But as with any data stream, the presentation and analysis of that information can be just as important as the data itself. A smart and intuitive interface is essential for proper flight planning and conduct, and Honeywell's Forge Weather Information Service provides that in spades. Equally useful for both pros and recreational pilots, it’s an easy recommendation for me to make.
