[QUOTE="tim_w, post: 1348735, member: 11132"] I know it's going seem like splitting hairs but it really is not. Its air density not altitude. Yes altitude is one of the two largest contributing factors that effects AD. 3000' @100 F might have the same effect on air density as sea level @ 25F . I did not check its just an example but to the point. temp and altitude both significantly effect air density. The difference can be quite dramatic as going from hot summer to cold winter could have you needing up to 2 inch change in twit rate to achieve the same stability factor. Not a big deal if at ICAO you are running 1.5 but below 1.3 and there can be real issues if you hunt in low elevations in winter. [/QUOTE]
