Most “Third world countries” are in warmer climates. Climate is not, at all, involved in these accidents. Draw your conclusion.
“Climate is not, at all, involved in these accidents.”
How can you draw this conclusion when none of the experts have done so?
Warmer weather, more humid weather, and less humid weather can and does affect the performance of aircraft. If a sensor is not correctly calculating the impacts of local climate then the calculated density altitude and pressure altitudes can be wrong. That could lead the flight computer to determine the aircraft is in a stall when in fact it is not.
Given that these aircraft have their final assembly in a relatively cool and wet Renton, Washington then there’s a good chance they were calibrated for Renton and not recalibrated for their new service locations.
