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.

Features
Read full description

Assure operation within aircraft limits by calculating Weight & Balance anytime, anywhere! For airlines who need to calculate airplane CG efficiently, the eWB is a paperless solution that reduces costs and workload, reducing average turnaround time. eWB is fully stand-alone, calculating Weight & Balance offline, generating a Loadsheet that can be sent to the ground or a printer. Benefits: - Assured operations within CG and Weight limitations; - Reduced Turn Around Time by reducing time to perform WB calculations; - Less paper! Reduces or replaces paper-based material, reducing costs; - Clean interface: straight-forward for pilots; - Analysis run offline: no Internet connection needed; - Support for all Embraer Commercial aircraft models; - Easy to update. Data enclosed in the application is provided for demonstration purposes only and shall not be used for operational purposes. Please contact Embraer for further information (opereng@embraer.com.br).
