Ok so I am I right with this:
If I happened to be in an aircraft right next to the metal on the inside of the aircraft that the outside air was rushing past, I would only ever notice the temperature of the metal going down to the TAT and not the OAT - i.e. because the air is moving so fast the temperature it will bring the metal down to would be the TAT and not the OAT, unless the air was stationery?
