Demo Tour

Start execution of flight

We want to show you the great possibilities of StrePla4 and pocket*StrePla with this demo tour. You can go through the tour step by step, or you can go directly to a specific area. The demo tour is split up into following areas:

Begin with the presentation of the various possibilities that pocket*StrePla gives you to successfully accomplish your cross-country flights.

 

Pocket PC's are small and powerful personal computers which run the Windows CE Operating System. Best known representative of this genre is the iPAQ from Compaq/HP but there are a lot of other units available on the market as well.

The touch sensitive displays of these units offer screen resolutions of 240*320 pixels on a typical screen size of 3.7". The size of the screen and the methods of data entry are somehow limiting the scope of use for these devices but make them still perfectly suitable for moving map SW. Especially in today's small Glider cockpits. The displays of the last generation PocketPC's are very good and their use of transflective TFT displays makes them readable in a large variety of lighting situations without the need for backlighting. This results in less power consuming than the displays of old technology. All current dataloggers and most other GPS units provide an external NMEA signal which is fed into the PocketPC for position information.

 

 

PocketPC's are produced in large quantities and therefore quite affordable. If such HW and SW would have to be developed and produced just for the Soaring community we would look at 5-digit $ prices per unit.

This infrastructure and the demand of many our customers wanting to use StrePla on their PocketPC in-flight was motivation for us to develop pocket*StrePla.

The Goal

Our #1 goal is and always has been to provide the soaring pilot with an easy to use tool in his/her cockpit which doesn't distract from flying the aircraft and observing the airspace. It should provide supporting navigational information like reachable airfields and avoiding airspace. In addition it should provide for the first time in-flight information on optimizing a flight for the OLC (Online Contest) and national decentralized competitions like they are run for example in Germany with the DMSt. So far there hasn't been any SW which assists the pilot in flying a "free" FAI Triangle. At the same time there has not been an Odometer which shows the kilometres flown for the OLC during flight. Free flights of 498 km or 997 km which were planned to have been 500 or 1000 km should not be a problem any more using pocket*StrePla. And last but not least pocket*StrePla should communicate easily and extend the functionality of StrePla desktop edition.

Navigation

pocket*StrePla is using the same maps which are used by StrePla as well. This has the advantage that StrePla users have to buy the maps just once and can use them with both SW packages.

It is better for planning a flight to use the vector maps(DCW) for the ability of having a good overview and selectable depth of details. There is an advantage of using raster maps(ICAO, Jeppesen) for moving map SW. In StrePla you can use either of them. The user can select a rectangular area in StrePla and directly export this map section into pocket*StrePla. It is as easy as that. It is with the same ease how tasks and turnpoints can be transferred between StrePla4 and pocket*StrePla.

The StrePla team has achieved very efficient memory use in pocket*StrePla which allows to store large areas of maps in PocketPC's without the need for a memory extension.

There are seven zoom levels for the maps in pocket*StrePla and the map sections can be moved with the touch of your finger. In case you moved your glider symbol (your current position marker) out of sight it only needs a "click" with your finger in the middle of the keyboard to re-centre the position marker in the centre of the display. The pilot therefore can concentrate at all times on the important tasks of flying the aircraft and watching the airspace. In order to see the most possible amount of "map area ahead" the position marker can be fixed at any part of the map. Or activate the auto modus which fixes the map position and re-centres automatically once the position marker reaches the border of the map area.

 

Arrival height of the reachable airfields

Without having to change the display page the pilot can see the arrival height for the surrounding airfields. pocket*StrePla is using an easy to recognize "traffic-light" modus for this function. If you can see the airfield name and (adjustable) arrival height in green - then you will arrive at the airfield at or above the chosen safety altitude. If you see it in yellow - then you will arrive at the airfield between 0 and the safety height. And red of course tells you that you better find a thermal or an alternate landing field. These calculations are based on the current position, the current wind direction and strength and your chosen glider parameters.

The StrePla team has chosen new methods to solve these tasks. In this situation, it is most important which airfields can be reached rather than how fast they can be reached. Therefore pocket*StrePla is calculating and adjusting to the optimum Mac Cready setting and takes into account if you are flying into or with the wind. The altitude is taken from the GPS if your GPS is not serviceing the altitude. As this altitude is not very accurate it is adjusted to the airfield elevation before take off to achieve best accuracy possible.

FAI Triangle information

So far there was no information available in the cockpit if you are still within the limits of a free FAI Triangle. The pilot was depended on guesswork or difficult calculations, which were not easy to do while in the air. pocket*StrePla for the first time is showing you the FAI triangle areas during the flight. This can be very important in some mountainous areas were very flat FAI Triangles are flown sometimes.

After a flight of minimum 20 km into one direction you will see the possible FAI triangle areas which fits this leg as a grey sickle shaped area. In the FAI infobox you can see how large the FAI triangle would be assuming you "close" the flight and land back home. In case the pilot decides to extend his flight on the last leg, then pocket*StrePla shows him a second FAI area which helps him optimize the flight into a FAI triangle with start on the leg. And even with these complex calculations there is no need for the pilot to "operate" pocket*StrePla. Keep your hands on the controls and your eyes on the airspace.

 

OLC Optimization

The OLC infobox shows the current result of optimization for the Online Contest (www.onlinecontest.org) of the flight. Therefore the pilot at any times has the information on OLC-Optimization of up to 6 legs and knows the score for his flight.

 

 

 

 

Barogram

New as well is that the barogram of the flight can be shown during the flight. This allows to set the exact times for the start of the flight to ensure correct optimization results.

 

 

 

 

 

 

 

Availability and Updates

pocket*StrePla Version 1.04 is now available. There are still many additional functions which we will introduce in future versions. For this first version we have concentrated to offer the pilot a powerful tool to fly in the OLC and national decentralized competitions like the DMSt. For pilots flying central competitions there are some functions like calculating AAT (Assigned Area Task) which are not yet implemented into pocket*StrePla.

All customers which buy pocket*StrePla will receive a free upgrade period of one year after sales. Updates will be available as downloads from our Website.
