Abstract: This invention described an air quality measuring device and vehicle performance predictor whereby normalized air quality conditions and vehicle performance factors are calculated based upon atmospheric and vehicle operational data inputs. The controller of air quality measuring device and vehicle performance predictor is connected to temperature, pressure, humidity, oxygen and light sensors. The sensor measure the ambient atmosphere and inputs the collected data into the controller. The controller calculates normalized air quality conditions such the oxygen content and moisture concentrations in the atmosphere. All stored and calculated normalized air quality conditions and vehicle performance factors are displayed on a visible screen on the controller, stored in memory of the controller and may be sent to a remote transceiver, printer or computer.

Abstract: This invention describes a density altitude measuring device whereby the density altitude is calculated based on atmospheric inputs. The computer of the density altitude measuring device is connected to temperature, pressure and humidity sensors. The sensors send input to the computer describing the ambient atmosphere. The computer then takes sufficient samples from the sensors and calculates the density altitude. Finally, the data is displayed on a screen, storage device, or printer.
