With smooth air at 4,000ft our Vl3 was cruising at 300kph tas, as we entered Brno airspace from entry point November we joined the downwind for runway 27 and slowed the VL3 down to below 150 kph we extended the gear then came the flaps. One minute we are flying 300kph and the next we are at a steady 120kph. As we were on final, tower instructed us to exit at taxi way Delta, so we touched down past taxi way Echo with space to spare.
