What is the approximate accuracy of laser velocimeter?(a) 1 knot and b

1.	What is the approximate accuracy of laser velocimeter?(a) 1 knot and below(b) 2.5 knots(c) 10 knots(d) 0.14 knotsThe question was posed to me in final exam.The question is from Helicopter, Optical and Hyper Sonic Air Data in division Air Data Systems, Altitude and Heading Reference of Avionics
Answer» Right CHOICE is (a) 1 knot and below The best explanation: Test results SHOW an accuracy of 1 knot or better at altitudes where the particle density is adequate. AEROSOL densities and particle densities vary with altitude, TIME and volcanic eruptions.
