1. Flight Checklists

  1.1. Preflight Checklist – Before Leaving for Field
      1.1.1. UAS accessory list
             ❏	Transmitter
             ❏	Radio with USB cable
             ❏	UAV batteries and battery chargers
             ❏	Propellers and extra propellers
             ❏	Tool kit (wrench set, propeller hex-key, camera mount screws and screw driver etc.)
             ❏	Gimbal
             ❏	Camera(s) with fully charged batteries 
             ❏	SD cards with CHDK installed
             ❏	Voltmeter (optional)
             ❏	Calibration reference panel and metal stand (optional)
             ❏	Ground Control Points installed (optional)
      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 x.x.. (Note: This step is required only once for each new phenotyping field.)
             ❏	Does RC Transmitter have enough voltage?  FrSky transmitter should have ≥ 9.4V charge.  
             ❏	Are UAV batteries charged? 3-cell batteries should charge 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 USA 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 people and in an open area.  
             ❏	Before the first flight make sure to perform a compass calibration otherwise this could lead to a bad behaviour in GPS enabled modes. You can perform the compass calibration through APM Planner or Mission Planner
