Aircraft Performance Group (APG) has released an application for use on the iPad, which integrates their Runway Analysis (RWA) and Weight and Balance (WB) system with a flight planning module. The combination of these functions allows the user to easily and quickly calculate the available payload for a planned flight – this service is known as MPE™ (Max Payload Estimator). iPreFlight™, has been developed to run on the iPad using the latest iPad technology. iPreFlight™ is a first-of-a-kind product that requires minimum user input to quickly calculate the available payload for a given city pairing, considering takeoff/landing performance limitations, manufacturers WB requirements and flight planning constraints. The flight planning element utilizes manufacturer’s operational data, in conjunction with current forecast weather conditions to calculate the fuel required for the flight. The fuel calculation includes fuel burn (optimized for minimum fuel or time), reserve, alternate and holding fuel. In addition to including the RWA, WB and flight plan, iPreFlight™ allows the user to prepare a Flight Book, containing all textual and graphical weather products for the planned flight. The book may be prepared days in advance of the flight, stored on the iPad and can be automatically updated as products are revised. Approaching departure time the user can easily prepare a Flight Release, consolidating the RWA, WB, flight plan and weather products. The Flight Release may then be emailed, stored on the iPad and/or shared with another iPad, such as the other fight deck crewmembers’, by simply selecting the appropriate distribution method(s). iPreFlight consolidates several preflight functions into one program, not only ensuring accurate takeoff and landing performance limits and correct aircraft loading, but allows pilots to quickly calculate the available payload and fuel requirements for a flight. In addition, iPreflight™ allows pilots to make last minute adjustments with just a few keystrokes. The Flight Release may then be saved on the iPad for review in-flight and shared with the other crewmember, Application Requirements: To use this application you must be an existing APG customer having a Runway Analysis (Point Calculation) and Weight and Balance services account.

- App tries to predict when you took off and landed and auto populates it for you. It is always wrong.
- Never get notifications even though I have them on
- What were the changes to my schedule?
- Post Flight data fails to push
- When selecting Duty time On and Off. should be a simple, one time selection. Shouldn’t have to Include All, and re-enter a yes, I’m really coming in duty!
- Jedesmal bei einem update wird man ausgeloggt, muss man wieder das Passwort eingeben. Weiters bei jeder Öffnung der App kommt ein beliebiger Tag im Jahr2022. Offline Eingaben nicht speicherbar.
- Try to do the post flight and just enter times - sometimes it populates all sometimes it just goes blank- waste of time for simple data entry - Never should have changed from FOS !
- Id love if there was a slider to show me when duty ends (and updates when block times inputted), when im unavailable to be called and when next duty will start.
- When I’m inputting data in the post flight section, or just using the app and flight updates occur (new flights being assigned or updated) a notification banner slides in from the top and deselects anything you were working on meaning you need to start again. When this happens in bursts like at my company (multiple flights being released for the next day for instance) it makes the app unusable.
- Also I get multiple notifications on my phone and watch when flights are released. If I have 7 legs tomorrow I get 7 back to back notifications on my phone and watch. It should just be a single notification that flight are released for tomorrow and I can review them in the app.
- Opening any document under recap crashes the app. Currently running on IOS16.0 (20A362)
- Painfully slow. Every 5th time I open the app it takes me back to January 2015. When inputting post flight data it will often crash half way through and delete everything imputed, needing to start again. Great ideas in this app, poor execution.
- Incredibly slow after last update (18 Sep22) Until yesterday everything was fine, but the last update slowed down the app at the point it is almost unusable. Tried to delete the app and reinstall, tried to log out and log in again, nothing works, takes ages to update and freezes every time something is selected.
- The app was broken before, now worse with the update.
- Absolutely too slow with this latest update, who ever said I care about birthdays. If that’s what is important as opposed to scheduling and record keeping and slowing it down. Please remove it.
- Terrible app
- The App constantly looses data entered
- Try finding how to enter times
- Worst most complicated app ever
- Appli plante tout le temps, très nombreux bugs, interface mal foutue, génératrice d’erreur, ne fonctionne pas off line, très longue au chargement. Je HAIS cette application et bon nombre de mes collègues s’accordent avec moi pour dire que c’est de la M**** J ai mis une étoile car on peut pas mettre moins
