for the engine to warm up as per real-world checklist) 2. Ensure both ECU switches are in "AUTO" position 3. Hold the mouse in between the two black ECU push switches until "ECU FAIL" annunciations disappear on the PFD. 4. The engine should cycle through a rise in RPM followed by a drop in RPM 2 times throughout the ECU test Note: ECU will not cycle until temperature and conditions are met. Headset Simulation The COWS DA42 has implemented and referenced real sound recordings from the Bose A20 to mimic its ANC (Active Noise Cancellation) feature. To enable headset simulation, locate the GA plug jacks found on the rearward side of the middle console. The click spot is the jack itself. Ignition Key The COWS DA42 has implemented a large area ignition key rotation click spot for ease of use. At times, the key may be hard to turn in one direction or the other. To ease rotation, move the camera towards the desired side of rotation and click-hold the key. Windows & Doors The COWS DA42 has various operable doors throughout the model: • The left front red handle within the cockpit operates the front canopy • The left rear red handle within the cockpit operates the rear door • The left & right storm window notch operate their respective window The COWS DA42 has the following inoperable doors: • The FWD baggage doors • The gearbox oil access panel • The fuel cap Flood Light The COWS DA42 has implemented an easier click spot for the FWD cabin flood light. The click spot is located on the standby airspeed indicator needle. Clicking it requires the battery to be on. The alternative method of enabling flood light is on the floodlight panel itself, on the roof between the pilot seats. Control Sensitivities The COWS DA42 flight model reacts appropriately across various control sensitivity settings. However, it is recommended that the user has flight control peripherals tuned to the right sensitivity options in the simulator We recommend only adjusting one setting, REACTIVITY: • Less than or equal to 30% across all control surfaces COWS DA42 Series POH Section II - Clickspots & Accessibility 5 Section III Important Speeds and Operating Limitations This section contains information on critical airspeeds and limits of the DA42.

COWS DA42 Series POH Section III - Important Speeds & Operating Limitations 8 Section IV Flight Planning Tips This section outlines tips and tricks to make a flight plan and calculate critical distances, time, and speeds for a general aviation flight. Below are techniques derived from real-world flying. For a more detailed outline, take a look at Mitchell's flight instructor lesson plan here: https://docs.google.com/document/ d/1CDCsDJOtiAs8b9_JyCJv7D92BZfXhUOdG7PNUJpSoug/edit?usp=share_link COWS DA42 Series POH Section IV - Flight Planning Tips 9 Flight Planning Tips Planning a Flight To plan a cross-country flight, using tools such as Skyvector, Foreflight, or Garmin Pilot will help aid your flight planning process. Begin by first plotting the departure and arrival airport. Then find waypoints in between, whether VFR or IFR, use visual waypoints on the map, or use VORS and NAVAIDS. Waypoints should be within 20nm to ensure navigational signal integrity and basic pilotage. After establishing waypoints, pick an altitude of over 2000ft AGL over the highest terrain or obstacle en route, then add 500ft if VFR. This will be your cruising altitude. Top of Climb To calculate top of climb, refer to the operating manual cruise climb performance chart to calculate rate-of-climb at your given weight. Then average that climb rate with the departure altitude and the cruising altitude. Then, divide the altitude difference (cruise altitude - departure field altitude) by the climb-rate. This will give you the resulting minutes it takes to reach top of climb. To calculate the distance, you will need to multiply your ground speed by the time it takes to reach top of climb (in hours). To calculate groundspeed, take indicated airspeed, convert it to calibrated airspeed in AFM, then use local winds aloft to add or subtract from the calibrated airspeed. Finally, divide the resulting calculated minutes above by 60 to convert it to hours, and multiply that by the groundspeed to determine how far out your TOC will be in NM. Top of Descent To calculate the top of descent, multiply the altitude difference (Cruise altitude - arrival field altitude) by 3. Move the decimal 3 places to the left and this will be the NM out that you will need to start your descent. To calculate how fast you should descend, take your groundspeed and divide it by two, add a 0 to the end and the result is your standard FPM descent rate on a 3-degree standard glideslope COWS DA42 Series POH Section IV - Flight Planning Tips 10 10 Section V Useful Links & Product Information This section provides users with links to useful documentation from official Diamond training checklists, to the paint kit for the aircraft if you want to get creative.
