Welcome digital WINTEMs!


In a nutshell…

With release 2.6, we are giving you access to digital WINTEMs.

That sounds nice indeed, but what is it bringing to the application:
– you will be able to display WINTEMs on the map (either for current time and altitude or for a time and altitude of your choosing)
– on the map, you can display a new widget that shows the forecasted wind
– you can as well access the current wind and temperature gradient. It will give you the head/tail wind component and the outside air temperature each 1,000ft up fo FL120. This can help you to choose the best altitude for your leg.

We have as well added a new “Situation” page in the cockpit.

This new page does what it says: it gives you information about your situation and it shall be really useful and improve your security.

It will give you a description of your location relatively to nearby aeronautical points (airfields, radio navs, etc.). This can be useful to answer ATC accurately (“6200ft, 3 nautical mile north-northeast of LFMT, 1 minute 30 seconds away”).

The wind and temperature gradient will be displayed on this page as well.

Finally, we have added a very important tab on this page that will give you real time information about your fuel situation.

Namely, how long must you fly to the touch down at your final destination, what is the minimum fuel to land, and what is the minimum regulatory fuel.

We consider that this last page is really important for the pilot’s safety.

Please read till the end, there are some terminology changes that you need to be aware of.

IMPORTANT NOTE: though we have not communicated about each update, all the aeronautical maps have now been updated to the latest 2017 issues.

If you are using an aviation map from Flight Assistant (either free or as an addon) you can update it by going to “My Account > My addons” and clicking the “Update” buttons.

Downloading digital WINTEMs

Digital WINTEMs are included in all Advanced subscription and above.

You can download the digital WINTEMs from the home page of the application (or the application status page on phones) by using the download button on the “Digital WINTEMs” line.

When downloading digital WINTEMs, you download 48 hours worth of weather forecast (as usual with weather forecast, the further in the future, the least accurate).

After 48 hours, the database will be deleted. We recommend that you download the WINTEMs before each flight or flight preparation.

Displaying digital WINTEMs on the map

On the map (cockpit or flight preparation) you can display the WINTEMs the “usual” way: each marker on the map shows the direction and speed of the wind and the température.


You can choose to display the WINTEMs on the map or not and what WINTEMs should be displayed. It can be either the current WINTEMs (for current time and current altitude) or the WINTEMs for a time and an altitude of your choosing.

To select the WINTEMs you want to display, use the “Overlays” button on the moving map. The “Weather” tab will let you select the WINTEMs.


On top of the WINTEMs markers, you can as well display a “current wind indicator” on the moving map (“on” by default, but can be disabled in the map settings).

This indicator shows the current (time & altitude) forecasted wing at your location.
If you are flying track up the indicator will be rotated as well.


The new “Situation” page

This new page carries three tabs that will give you information in different domain but that all target the same thing: increasing your situational awareness.

The wind and temperature gradient

When flying, it is always useful to know how you can optimise your head / tail wind.

With the wind gradient, you can assess the impact of the wind at your current heading from 1,000ft up to FL120. The temperature can as well be useful, so we have added it to.

In this example, we do have 13 knots of wind coming from our right side (roughly 4 o’clock).

At our current heading, we do have headwind up to 3,000ft and we can maximise tailwind when climbing to 7,000ft.

Note: You can access the wind gradient directly from the moving map by tapping on the wind indicator on the moving map.

The fuel and overview tab

With digital WINTEMs now on board, we can refine constantly the fly times with the highest degree of accuracy.

The fuel overview and overview tab tells you about the flight ahead.

Basically, how far (distance) are you from your final destination, how long before touch down (including approach time), how much fuel to get there at the minimum and how much fuel to meet regulatory requirements.

With this information at hand, you can reassess your fuel situation at any time during the flight and you can make an informed decision if you need to land for refuelling or target an alternative destination.


The “Situation” tab

The purpose of this tab is to give a representation of your location relatively to aeronautical points around you.

Hopefully you know perfectly where you are with the map, but we thought this page would be useful to answer ATC for example as you can almost read it out when asked for your situation.


Other changes

Changing fixed times in a  flight plan

Our flight planning module caters for fixed times for taxi, approach and security.

Those times used to be preset, but you can now change them in the flight preparation page (navigation log view).

Just tap the field that you want to change (taxi time, approach time, security margin time or regulatory reserves time) in the navigation footer (the green area) and enter the new value.


Displaying remaining fly time and landing time

You can now display the remaining fly time and the landing time on the moving map.

To save screen room the ETE (Estimated Time En route) field can now display both the ETE to the current TO waypoint or the remaining fly time (including approach time at destination).

Just tap on the field to cycle thru values.

Similarly, the ETO field (see below) will show either the ETO (Estimated Time of Overflight)  or the landing time (as well including approach time at destination).


Terminology change

When displaying the estimated time (hour) at the next fix we have decided to change ETA (Estimated Time of Arrival) for ETO (Estimated Time of Overflight).

With ETA, we felt that there was a doubt for the destination: it was not the time you will actually arrive (land) at destination as it was missing the approach time.

With ETO, this is clear that it is the time you will arrive overhead the fix. If this is your final destination, “Landing time” (that you can display in the same field) will include approach time and this gives you an all inclusive estimate of your touch down time.


Changing the height of the flight profile

Some users did raise that the flight profile was not tall enough, especially on small screens.

We have a included a setting in the moving map that allows you to choose the height of the flight profile.


Displaying the height above ground

We have added a gauge to display the height above ground in the flight profile.

Beware though, this is obviously not a radio altimeter reading!
The height of the terrain below is averaged on a little square (little relative to your speed) and it is the height over this average that you are reading.
