Airspeed Indicators - Knots Vs MPH ????
I was just reading the thread regarding the "PA28R Glide Speeds", and without hijacking that thread I was wondering about Airspeed Indicators...
In Australia we use Knots displayed on the AI. But I see some refer to Miles Per Hour (MPH) on the their aircraft AI's. Is this just an American thing, or all around the world??
I've been involved in aviation for 22 years now, but have always dealt in Knots, tho some Flight Manuals have had some readings in MPH. Without being too nieve, what is the world standard?? Who uses what?? I wish that would just use the one speed to simplify things when reading international posts
