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

Verdict

The call

The clearest difference is review sentiment: VOCUS Safety at 100% against Textron Aviation Cesnav's 43%. VOCUS Safety also leads on monetization model (free vs subscription) and update cadence (every 2 months vs every 4 months). Textron Aviation Cesnav's advantage is rating (5.0 vs 4.5) and iOS requirement (13.0 vs 16.4). On price, ads, in-app purchases and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Textron Aviation Cesnav holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: VOCUS Safety has 16 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 43% of Textron Aviation Cesnav's written reviews are positive against 100% of VOCUS Safety's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Textron Aviation Cesnav ships an update every 4 months, VOCUS Safety every 2 months. The most recent releases landed on November 1, 2026 and November 2, 2026 respectively.
