From sea level airports with long runways to high and hot airports with runways that are not as long as you would like, ULTRA-NAV Performance Software will compute and display performance numbers derived from your aircraft's AFM with ease, speed and accuracy. The ULTRA-NAV Performance Software will compute maximum allowable takeoff weight based on ALL limiting factors - field length, climb limitations, brake energy, etc. The ULTRA-NAV Performance Software will then compute and display takeoff distance, all "V speeds", 2nd segment climb gradient, takeoff thrust setting, and other pertinent takeoff parameters dependent on aircraft type.

For landing data, Ultra-Nav computes and displays all "V" speeds, landing distance, landing field length, approach climb gradient and landing climb gradient.

Ultra-Nav can also customize weight and balance to your aircraft's exact seating configuration. Software will compute weight, %MAC and C.G. Limits for Zero fuel, Ramp, Takeoff and Landing conditions of your aircraft.

DEVELOPMENT: To develop aircraft performance software, Ultra-Nav derived advanced mathematical techniques which are used to transform Airplane Flight Manual (AFM) graphs/data into modules of powerful equations, which predict all the linear and non-liners shapes and forms of the AFM graphs/data. As a result, Ultra-Nav Performance Software allows quick and accurate computations to be performed; just as you would with a straight edge and pencil but with split second speed and without the eyeball and interpolation errors. In addition, Ultra-Nav programs all the AFM protocols and procedures that dictate exactly how all the charts are to be used together to give a complete and accurate analysis of your aircraft's performance as a function of ALL permitted combinations of altitude, temperature, runway length winds, runway slope, obstacle, etc.

The Ultra-Nav does NOT use tab data or data entry look up tables where linear interpolations are done between data points and "rounding off" procedures are commonly applied. Ultra-Nav Software is a real regeneration of the AFM graphs/data and the true curve forms they represent.

EXPERIENCE BASE: What makes this transformation of AFM graphs/data into software possible are the unique combinations of skills and backgrounds accumulated by the Ultra-Nav software designers. Software designers, Charles Mire and Dejan Rajcic, have nearly 40 years of combined experience as licensed instrument, commercial, multi-engine and instructor pilots. Both have graduate degrees in Physics and over 40 years of accumulated experience in developing and applying advanced mathematics to solve analytical problems. Combine all this with over four decades of using programming languages to crunch advanced mathematics; Ultra-Nav software designers have the perfect mixture of ingredients to tackle and properly tame the complex problem converting AFM graphs/data into hard working software.

The Ultra-Nav Performance Software is Windows compatible and runs on all Windows computers, including (EFB Tablet Pcs).

Benefits of Use

FUEL CONSERVATION: With Current Fuel Prices, it is more Important than Ever to Compute Precise Maximum Takeoff Weights Before getting into the Cockpit. Since computations are made straight from the AFM graphs and charts, accuracy is consistently better than eyeballing the charts with a pencil or using tab data. Therefore, precise Max Allowable Weight computations made by Ultra-Nav allow for more accurate knowledge of fuel loading needed for every trip you take. The extra accuracy in computing max allowable takeoff weight will result in FUEL COST SAVINGS over a year's worth of trips. As a result of this savings, the Ultra-Nav usually pays for itself within one or two trips.

SAFETY: No matter if it is a short runway or a high elevation airport with SID gradients to meet, the Ultra-Nav accounts for and Simultaneously Computes ALL Weight Limitations defined in the AFM (i.e. Field Length, Obstacle/SIDs, WAT limits, brake energy and tire speed). Since the software computes performance numbers so quickly, within seconds, a pilot may compile a detailed picture of the aircraft's performance by executing, within a few minutes, many different takeoff scenarios by recomputing numbers with varying temperatures, winds, runway directions, etc. Also, the time saved with the Ultra-Nav allows a pilot to spend more time on other safety related issues concerning the flight.

Ultra-Nav Aviation, Inc. has produced Aircraft Performance Software since 1990. Performance Software development initially took place for a corporate flight department operating both a FA 50 and a FA 900A. Once these two products were exposed to the corporate aviation market, demand for the performance software expanded to the current bizjet fleet listed. Demand has also resulted in Ultra-Nav engaging development plans for every existing, new and upcoming business jet in the market today. Ultra-Nav has also engaged in performance software development for military aircraft.

Serving flight departments across the United States and world, Ultra-Nav has provided many corporate flight departments with a safety tool that allows an accurate, fast and easy way to compute takeoff, landing and weight and balance numbers for any takeoff and landing scenario.

Reviews of the Ultra-Nav Performance Computer have appeared in several professional publications, including the most recent, Aviation International News, March 1998 issue. An interview with the product developer appeared in the Business section of the Lubbock Avalanche-Journal on Sunday, April 19, 1998.
