Bolder Flight Systems

OnFlight Hub

OnFlight is a family of products to provide high quality data logging to the General Aviation pilot. OnFlight is ideal for student pilots, CFIs, experimental aircraft builders conducting their Phase I flight test program, and pilots who would enjoy to see their previous flights and their performance. OnFlight Hub is the central component and includes:

  • 50 Hz sample rate, logging to a micro SD card
  • High accuracy GPS-aided INS
  • Data available in MATLAB or CSV format
  • Integrations with CloudAhoy and FlightData web apps
  • Real time streaming to ForeFlight for use as a GPS source and a backup AHRS
  • 13+ hour battery life, 2.5 hours to charge with a USB-C port
  • Wireless integration with a wing-tie down mounted portable air data probe
  • GoPro and tripod adapters provide flexible and fast mounting options

OnFlight Air

Bolder Flight Systems is developing a portable air data probe, OnFlight Air, which will be able to quickly attach to wing tie-down bolts and wing struts. OnFlight Air will measure static and dynamic pressures, Outside Air Temperature (OAT), indicated airspeed, true airspeed, pressure altitude, density altitude, and angle-of-attack. Data is transmitted to OnFlight Hub for logging.

Pre-Orders

Bolder Flight Systems has currently manufactured 100 OnFlight Hubs. These are currently being tested on the ground and in flight. We are accepting pre-orders; your credit card will be charged when your order is placed. If you're one of the first 100 customers to place an order, we anticipate shipping OnFlight Hub by October 31, 2023. We are currently putting together another manufacturing run and we anticipate that these will ship by December 15, 2023. Orders will be fulfilled in the order in which they are placed and we will accept returns up to 1 year from the date that your OnFlight Hub is shipped. Following this second manufacturing run, we will maintain regular availability of OnFlight Hub in our store.


Pre-Order: $299


OnFlight Air software was prototyped and tested using components from our other data acquisition and flight control systems. Prototypes of OnFlight Air are currently in manufacturing and will be in flight testing in fall of 2023. We anticipate general availability in early 2024. We are not accepting pre-orders of OnFlight Air at this time.
