AirN@v for AMEL AMM/TSM is not via wifi.
AirN@v is installed from CDs for relevant aircraft which would work along with internet explorer and Windows 7, not sure about Windows8.
MS Surface RT is not Windows 8 professional version but a cut down Windows version which AirN@v may not work.
I am asking if any AMEL has tried installing AirN@v on MS Surface RT to see if it works fine as in the case of laptop which we AMEL are carrying all the time. Laptop is just too bulking and battery life is limited.
