1 Safety
The Impossible US-1 is a high performance electric aircraft intended
for operation by trained pilots. The aircraft presents several safety
risks beyond those of a lightweight consumer drone.
With the standard payload option, the aircraft weighs approxi-
mately 20 pounds. A falling vehicle can cause significant damage.
When spinning, the large aircraft propellers are difficult to see and
pose a significant hazard to nearby personnel. In addition, the fully-
charged aircraft contains 1.2 kilowatt-hours of energy - an amount
of energy equivalent to a kilogram of TNT.
US-1 can be safely stored, charged, transported, and flown when
proper procedures are followed by a qualified operator. While this
handbook is a compendium of relevant information, it is ultimately
the operator’s responsibility to ensure they have the necessary train-
ing to safely operate the vehicle. Operators must familiarize with
not only this manual but also any applicable Impossible Aerospace
service bulletins before flying.
When operating the US-1 in U.S. Airspace, always operate within
the restrictions specified within Part 107 or an applicable COA.
When operating outside of U.S. airspace, please confer with the rel-
evant aviation authorities prior to conducting flight operations.

The FLIR Duo Pro R and Gimbal optionally delivered with US-1 are
pre-balanced and ready to support flight operations. The Flir Duo
Pro R comes with two microSD cards. Prior to each flight, ensure
that the cards are emptied and inserted to enable data collection.
To review data from a flight recording, simply remove the microSD
cards and import the data to your computer or preferred storage
platform.
For more information about the FLIR Duo Pro R, please reference
the device’s manual, available on the FLIR website.
