iPreFlight Genesis™, the next generation of iPreFlight, integrates flight planning, takeoff/landing performance limitations, and manufacturers’ weight and balance requirements with only minimal user input required. The flight planning element uses manufacturers’ 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), and fuel for reserves, alternates, and holding. Along with runway analysis (RWA), weight and balance (WB), and flight planning, Genesis allows the user to prepare a trip book containing all textual and graphic weather products for the planned flight. The trip may be created days in advance of the flight, stored on the iPad, and can be automatically updated as products are revised. Or if needed, Genesis can create flight plans without an internet connection by using historical weather information, and then can be updated when internet is available. Approaching departure time, the user can easily prepare a flight release, consolidating RWA, WB, flight planning, and weather products. The flight release can be emailed, stored on an iPad, and/or shared with other flight deck crew members.

Features
Read full description

Cesnav combines three calculators (Previously known as CLCalc, CPCalc, and EOM) into one app, offering a unified experience from sharing calculations across the calculators to a combined results screen. • The Loading calculator uses an aircraft-specific weight and balance file and allows you to quickly determine your takeoff and landing weight and CG after entering your passengers, cargo and fuel load. • The Takeoff and Landing calculator is an excellent tool for determining engine-out performance in areas where obstacles or terrain clearance is a factor. It is easier, faster, often provides better field performance and higher takeoff weights than the AFM data. • The Planning calculator uses a worldwide airport and navaid database to plan a route calculating trip time, fuel and distance. Many models also feature Cessna’s exclusive GreenTrak technology which will optimize your flight based on DOC and fuel costs, resulting in the minimum total cost. • You can export, print and email PDFs of passenger manifests, loading sheets, performance, and planning results to take on-board. Cesnav is available for all current production Citations and the following models: CitationJet, Latitude, Longitude, CJ1, CJ1+, CJ2, CJ2+, CJ3, Bravo, Encore, Encore+, Excel, XLS, Sovereign, and X. The Loading calculator can also be used with any 550, 560, S550, 208B, or 208 aircraft (208 with TKS currently not supported). New aircraft deliveries include a subscription for the warranty period of the aircraft at no additional charge. App requires a subscription
