1.1.2. Things to check before leaving for field
❏ An updated version of Mission Planner Software is installed on the field laptop.
❏ Has the field map been cached in the Mission Planner program? Details on map caching procedure are discussed below in section 2.4 (Note: This step is required only once per phenotyping field.)
❏ Does RC Transmitter have enough voltage? FrSky transmitter should have ≥ 9.4V charge.
❏ Are UAV batteries charged? 3-cell batteries should charge up to 12.6V.
❏ Is the laptop charged? Do you need/have a laptop charger?
❏ Ensure that you are familiar with the laws and regulations related to flying UAVs in your country/area. General laws in the United States require 400 feet maximum height and within line-of-sight flying.
❏ Make sure you have watched all the UAV manufacturer recommended tutorials before your first flight.
❏ When first flying your IRIS+, make sure to fly it away from populated areas and only in an open spaces.
❏ Before the first flight, make sure to perform a compass calibration otherwise this could lead to a bad behavior in GPS enabled modes. You can perform the compass calibration through APM or Mission Planner programs following this youtube video[1].
