COWS Updates DA40/DA42 for MSFS 2024
Quick summary· AI-generated
COWS has pushed significant updates to their DA40 and DA42 payware aircraft for MSFS 2024, overhauling flight models with retuned controls, balance, and pitch dynamics; upgrading engines with modeled PowerFlow exhausts and improved FADEC/ECU procedures; rebuilding the G1000 audio system with smoother handling and fixed cutouts; and refining systems including fuel sensors, battery charging, and pitot heating. The DA42 additionally receives an overhauled hydraulic landing gear system with pressure drops and accumulator simulation. Quality-of-life additions address nosewheel animations, keybindings, and documentation.
Excerpt from Threshold
COWS has recently issued an update to their DA40 and DA42 for Microsoft Flight Simulator 2024, bringing flight model improvements, audio and avionics enhancements, multiple bug fixes, and more.
Update V1.2.0 (DA40) and V1.3.0 (DA42) bring a full rework of the flight model on both aircraft, with retuned flight controls, balance, surface friction, and pitch dynamics. Furthermore, it also upgrades the power plants with a modeled PowerFlow exhaust, overhauled FADEC/ECU procedures, improved oil and temperature physics, and tuned fuel/mixture dynamics (DA40), whereas the DA42 gets an overhauled hydraulic landing gear system (pressure drops, accumulators, and leakage), improved propeller governor response, and updated ECU simulation.
The G1000 audio was rebuilt, with smoother audio handling, fixed cutouts during camera swaps, corrected AFCS altitude/AP disconnect tones, and added traffic callouts. The systems were refined with refined fuel sensors, battery surface charges/overcharging, pitot resistive heating, and strobe power pulses.
The update also brings quality-of-life additions and fixes, such as resolved nosewheel animations (DA40), maintenance and keybinding improvements, and documentation updates. The complete changelog follows below:
