Bill N Posted May 23, 2019 Share Posted May 23, 2019 Description and Use Case: Instead of asking the user to determine whether there is a headwind or tailwind, maybe ABRP could just ask what the wind direction and speed is - and then determine whether that means headwind or tailwind depending on the route that is planned. This would also help in the case of the circular routes (eg when using round trip mode). At the moment, the headwind / tailwind setting can't really be used in tandem with round trip mode. Even better would be if ABRP could just ask the user to input the time and date for the journey, and the pull the current or forecast wind direction and speed data and apply that to the model for the specific route automatically. As a minimum, perhaps a link to recommended website (eg. windy.com) to find out wind data could be included in the settings screen just beneath the wind section. 2 Link to comment Share on other sites More sharing options...
gday Posted June 14, 2019 Share Posted June 14, 2019 I just did a round trip with a tailwind then a headwind. I figured one would effectively cancel the other so the only thing that would be technically inaccurate would be the percentages each way but overall it should not matter - am I wrong? I am creating a fill in spreadsheet for me to compare predicted ABRP stats with reality . Has anyone already created one? What information would be useful data to record? These first trips are short so maybe the data is of limited use but I have a longer trip next week so hopefully the comparison may have some use to help the Alpha model - 2020 Kia Soul EV 64kW.

If it was point A to B and then point B to point A via the same route then my understanding is the wind (and elevation profile) would *mostly* cancel each other out; however, my understanding is the benefit gained from a tailwind (and/or a down hill) is not necessarily equal to the losses incurred due to a headwind (and/or an up hill). Also, when I started this thread, I had in mind a route that went from point A and back to point A, bit via points B, C, D etc... i.e a ‘circular’ round-trip, rather than a bi-directional, linear ‘round-trip’. In the case of a circular round-trip, the winds may be completely different for different sections of the route, and even if they weren’t and the route was a perfect circle, I’m not sure the impact of the wind would be negated.

derniko Posted June 19, 2019 Share Posted June 19, 2019 Hi yes, also I wrote an suggestion to get all weather data based on the GPS location Should be enough to calculate the data based on the route you choose. And it could be updated by the time you start your route Regards Niko 1 Link to comment Share on other sites More sharing options...
Nagaman Posted October 8, 2019 Share Posted October 8, 2019 As a pilot of old, I love the planning process as an efficiency exercise. A headwind is substantially worse than the benefit of the tailwind. Are the weather factors taken into account, including wet roads and temperatures, in the planning app?.
