oops I read your question wrong.....sure you loose wind reading on touchdown. but you dont loose your g/s inication on the top left corner of your nd until after a few min after shutdown. nd 1 displays g/s as recorded by irs1 nd 2 by irs2 and to check on irs3....I was refering to g/s all along.....sorry once again.....as for your qest...'wind"....I am clueless at the moment....will get back if i find something........
