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
