They do not have a normal pay portal, they require electronic wire transfer which is a 35$ fee to me from my bank or a mailed in check which they have failed to process several times where I had to mail in replacement checks that resulted in overpayment. Now they are claiming I did not pay 2 invoices from a year ago…. Impossible to deal with. I canceled my subscription ### 2/5 — No zoom in opt *2025-02-23* Still no zoom in option. NOTAMs, METAR and TAF is too difficult to read due to very small fonts. Very hard to use for users who wear reading glasses. This option has been requested for years, but was still ignored. ### 5/5 — Seeing some good improvements to this app *2024-12-10* I like the recent turbulence insight additions- SkyPath few months back and IATA EDR last week. Occurrences are getting more frequent, so these are great to have ### 3/5 — Reliability *2022-06-20, version 2021.2.1* In recent months, the software has been improved significantly. Yes, I think it remains for use primarily for a fleet of aircraft, small or large….But it runs much better then it did before and the functionality of things are better as well. I can reliably highlight places on the flight log and then I can actually delete the same markings. A big improvement. Overall, it’s gotten better. Keep up the good work. Update: After many months, its still working well. No complaints. ### 2/5 — App intermittently logs users out-deletes favorite charts *2021-09-09* This application continues to log me out at irregular intervals. That in and of itself isn’t that big of a deal, however when I log back in all my favorite charts are gone. I save them in a particular order for my self briefing. What’s more is that I must add the charts back in, in reverse order of viewing. There’s no function that allows shifting the order of charts saved. ### 1/5 — What is this *2021-08-19, version 2021.1* Couldn’t figure out how to create a login. I just wanted to look at weather… ### 2/5 — Radar Data *2020-08-01, version 2020.1.2* I am using version 2019.2.2 and it loads the last 5 hours of radar depicting data before running radar. This takes a very long time especially using the aircraft WiFi system, usually over 10 minutes. And if you change the area of depiction, it restarts the loading process. As a pilot, I do not need the previous 5 hours of data and I don’t usually have the time in flight to wait on it to load to make decisions. So using the radar in this version is worthless. ### 1/5 — Useless *2020-04-16, version 2019.2.2* Nowhere does it say that you must have an account to use this app. And there is no way to set up an account either. From what I can gather it is for commercial fleet operators only. WHY NOT SAY THAT IN THE DESCRIPTION! ### 1/5 — Deceptive *2020-01-23, version 2019.2.2* Unless you are a corporate customer, this app doesn’t work. It downloads, but unless you have the sign in information and password, no weather information is available. Don’t bother downloading this app unless you work for an airline. ### 3/5 — Latest Update Causes Issues *2019-12-02, version 2019.2.1* The most recent update took away the passenger brief module on airport weather and now causes long (timing out) downloads resulting in incomplete weather package downloads. ## Frequently asked questions about WSI Pilotbrief Optima ### What does WSI Pilotbrief Optima do?
