I use this app for each flight! Keeps crashing! ### 1/5 — Version 2.1 unstable *2013-05-22* This is a very handy app. Unfortunately the update 2.1 keeps crashing on my iPad. ### 1/5 — Needs work *2013-03-29, version 2.0.1* The alternate interior configuration does not work for special use or Air Ambulance. ### 1/5 — Doesn't work *2013-01-12* The past version I had worked great and was very helpful. Whatever update they did killed it. I can't get the new version to run the take off performance numbers. Deleting and reinstalling does not fix the problem. ### 1/5 — Please fix the crashing!! *2012-11-03* Please fix the crashing ### 1/5 — Almost there! *2012-10-30* This is an excellent first attempt at this app. It does need a few improvements though: - Passenger weights only go up to 300 pounds. It is unusual to have a passenger that weighs more than this, but it does happen. - The baggage weight only goes up to 265 pounds instead of the300 pounds that is allowed. - No accommodation is made for the extendable baggage net either which we have in one of our airplanes. - We need the ability to have multiple airplanes. We currently have two airplanes with different interior configurations, and are about to add another. Update: not only have none of original complaints been fixed, the app now crashes on iOS 6 any time I try to enter a baggage weight. Come on Pilatus!!! ### 1/5 — Crashing app *2012-10-26* Please update the app it's annoying that it keeps crashing ### 1/5 — Crashes *2012-10-26* Can only enter T.O. data, any other data entry crashes the app. Not very useful. ## Most critical reviews (10 lowest-rated) ### 1/5 — What strange user interface *2023-01-29* It is impossible to change data points. I put some dummy figures to get a feel of the app. Now I can’t change them to real values. Very poorly defined program. Delete and reinstall as the option. ### 1/5 — DO *2014-07-16* This app is essentially useless. Inadequate instructions on how to get past the first page. Designed by an engineer who knows little about the demands of flying and importance of timely inputs. Half assed attempt to be useful and I know this is cruel, but please find someone to fix this and make it easy to use. ### 1/5 — Not a flight manual! *2014-07-13* I was hoping to have a digital and maybe somewhat interactive POH to have on my phone/iPad to study, however, this is essentially not much more than any e6b app you can download just already configured for the PC-12. I'm not saying it's a terrible app, it's just borderline useless IMHO, and doesn't have any of the information in it I was hoping for. ### 1/5 — Still useless. *2013-09-26, version 2.1.1* Freezes when trying to input aircraft data. Currently using ipad 4 with IOS7. I couldn't get it to work on IOS6 either. ### 1/5 — Was an awesome app *2013-09-01* The current version is incredibly unstable. Otherwise It was amazing. I like the customizable w&b but I would like in the next version of the app to be compatible with other apps like foreflight, etc. it's annoying to be always put in all the flight information. ### 1/5 — Crashes *2013-08-22* When customizing interior the app freezes up. Forcing a close disables the app from further use. (Automatically closes itself before I'm able to accept the warning page.) Only way to get the app working again is to delete and then re-install the app. (I am using the iPad mini with iOS 6.1.3) this app is very useful when it works (5 stars) ### 1/5 — Very Disappointing *2013-07-04* Continuously freezes up. After restarting the app then it just crashes. Wish the app was as solid as their planes... ### 1/5 — Crashing please fix!!!! *2013-06-04, version 2.1* Please fix this app!!!!! ### 1/5 — Keeps crashing *2013-06-03* The new update continually keeps crashing. Very big pain due to the fact it gets used everyday on multiple legs. The new update has rendered the app useless...............uninstalled the app and reinstalled it, now it doesnt work at all. ### 1/5 — Please make sure it works before sending out an update! *2013-05-30, version 2.1* I have just updated only to find that all my saved aircraft and configurations have been deleted. When I try to amend a configuration the app crashes and then won't reopen. I then have to delete and re download! Please sort this out Pilatus! ## Most praised reviews (9 highest-rated) ### 5/5 — Excellent *2011-10-15* Outstanding program. Helps a lot. Thanks. ### 5/5 — Amazing App!!! Brilliant. *2011-10-15* Thank you for developing excellent tool. This is very useful and helps conduct a safe and thorough review before flight. Tks. Mike.. ### 4/5 — Great quick reference *2016-01-16* This is a great preflight planning tool as well as a quick reference in the cockpit. I would like to see it include data for landings in pusher-ice mode though. Overall solid app for anyone who flys the PC-12 regularly. ### 4/5 — Remove old version first *2012-12-02* Since no one from Pilatus has answered. I tried to delete the current app then install the new one. That worked fine so do not do the "update" option. Just remove and reinstall. ### 4/5 — Won't open *2012-11-17* The app won't even open. Crashes before starting up! ### 3/5 — No pull Down abilities *2018-04-14* Thanks for getting this app 60% there but the time and errors can get reduced once you guys get it to pull live data and airport information to auto populate most of the input information. Would also like to see the 45 fuselage with the 67P up front as an option ### 3/5 — Flt department *2012-10-19* A lot of problems with the iOS 6 Constantly crash ### 3/5 — Bugs since iOS6 *2012-10-02, version 1.03* Used to work well and very useful. Since latest iOS update when you try and enter climb parameters it crashes. Entering take off, cruise, etc all work fine still. ### 2/5 — Not Your Swiss Watch *2011-10-28, version 1.01* At first blush, the app is presented in an attractive and functional user interface. Buttons and options are well placed, easily accessed, with computations readily presented for analysis. If this were the only criteria upon which to rate it, I might have given it 4 stars for the first-out-of-the-gate issue. However, the exhaustive and repetitive disclosures, disclaiming responsibility and reliability, aroused my curiosity about its usefulness. In analyzing the Maximum Cruise Power settings I discovered that the app calculations diverged, lower as the temperature rises for torque, fuel flow and TAS, than presented in the POH. And no calculations are provided by the app for many of the "in-limits" flight regimes that exist in the POH. Obviously, it would be very helpful to have another option to the POH performance charts or the Simcom power setting matrix. And granted, I only evaluated the one area. But given the seemingly routine ability to plug in the known look-up-table database contained in the POH, I am rather discouraged about the app's overall usefulness. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
