Meteorological Conversions. The UK map shows Basic Mean Hourly windspeeds with the contour lines defining areas A,B,C and D. Windspeeds are shown at sea level and for every 100m increase in altitude, the Basic Mean Hourly windspeed increases by 10%, then giving the Site Mean Windspeed. During the wet season, there isn't much roll.GOLF TIP: During the cooler wet season, play the forward tees to shorten the course. The figures provided here are a very rough estimate. You need to specify the altitude at which you would like to perform the calculation as well as any one of the four airspeeds. Your fitness level is then converted to an equivalent 10K time, for easy comparison with other race results at different distances. The big advantage of using IAS in the cockpit is that the aircraft will always stall at the same indicated airspeed (for a given aircraft configuration) regardless of the altitude or ambient temperature. Of course the ambient temperature will decrease as altitude is increased, leading to the reduction in the speed of sound as with increasing altitude. Wind/Temp Plots. The Winds/Temps page provides 2D graphics of winds and temperatures at a multitude of altitudes from the current time until multiple days in the future. Vg= gradient wind speed assumed constant above the boundary layer. stability parameter. The programme will then calculate wind speeds for other heights. Category C flight phases are defined in reference [1] to be terminal flight phases, which include takeoff, approach, and landing. In reality there exists velocity gradients all over the aircraft, especially in regions where there is substantial curvature (forward part of the fuselage, windshield, wing surface). the plume centerline when the emission source is. The speed of sound in the atmosphere is a constant that depends on the altitude, but an aircraft can move through the air at any desired speed.
