If the pilot or passengers set the TEMP/°C selector to the maximum heat
position, the bleed air system automatically switches from the P2.5 to the P3
bleed port to increase the temperature and flow rate of the incoming bleed air.
Except in the case of very cold environmental conditions, this switching is
inhibited below 25000 ft.
