Figure 20: Air temperature vs. air speed
This diagram is based on estimated data and may change.
•
0.5 m/s airflow means convention cooled only.
•
The core temperature of the CPU can be read out via the onboard
temperature sensor. The value must be kept below 95 °C for all operating
conditions. This value is already included in the airspeed diagram above.
