Foreflight is certainly a popular service and most of the clients I served when I worked as a simulator I.P. used it (companies like XOJet, Flight Options, etc. and most corporate ops) … but our fellow Member Karl Towle talked me into trying Fly-Q because they offered a subscription to CFIs for only $20/year.
Fly-Q appealed to me as a competitor to the Boeing/Jeppesen/Foreflight “monopoly” anyway. Then a truly remarkable program was developed by Fly-Q for CFIs… a lifetime subscription for $300… and I took advantage of that. I really enjoy using it in conjunction with the ADS-B IN on my I-pad also overlaid upon the charts. (the charts and updates include all of north and Central America, Gulf and Carribean.)
(Last nite I was giving instruction to a student pilot and we shot approaches and was able to utilize the chart plan-view to follow progress on the approach-plate-proceedure.)
Anyway…as for flight planning….. Fly-Q provides the same flight planning service as Foreflight does… the only requirement being to open an acct with Leidos (FSS) and then link/authorize Fly-Q access to your account.
Of course, once you have a Leidos acct you can also get the briefing and flight plan filed via that online site: 1800wxbrief.com
(while on that topic…. there’s a “glitch” at 1800wxbrief.com / Leidos …. in that when you register your aircraft data …. you’ll get “invalid” warnings when you enter
cruising speeds and altitudes …and they don’t give you ANY help on Format. The answer I got by finally getting in touch with a specialist: Speed and altitudes must be Four-Digits… And the speed will be in “knots”. (DOH) .. indicated with a “N” in front of the digits.
so 105 kts is entered thusly: N0105
Altitude is entered thusly: A0750 (for 7500’) etc .
Hope this helps.
