![]() "Doug" wrote in message oups.com... GPS groundspeed is indeed useful for aviating. You are straight and level in IMC flying along into a 20 knot headwind at full power. Your indicated airspeed is 70knots (80 knots true at your altitude and pressure etc). You notice the groundspeed is 80 knots. All is well. You get ice, and note your indicated airspeed has dropped to 50 knots. But you note your groundspeed is 75 knots. Are you on the verge of a stall that 50 knots indicated would tell you? Or are you still flying as IIRC, the point ws in FLYING THE PLANE DURING AN EMERGENCY. Navigating is secondary (way secondary) during the incident in question. -- Matt --------------------- Matthew W. Barrow Site-Fill Homes, LLC. Montrose, CO |
