February 11, 200422 yr Hi- Could somebody explain how to calculate approach speeds with the wind factored into it?Thanks ;)
February 11, 200422 yr Standard would be VREF30+5Knots.If VREF30 = 132, then you would fly the approach at 137kts.IIRC for gusting winds it is VREF30+1/2 the Gust component up to a maximum of 20 knots. In some cases you may need to fly a Flaps 25 approach.
February 11, 200422 yr no markthe procedure for gusting winds is as follows:VREF30+ 1/2 steady wind component + (gusting component - steady component)if this goes over VREF30+20, then use VREF30+20Greetings*EDIT*:example:KMWN 112051Z 30053G64KT 1/16SM BLSN FZFG VV000 M22/M22 RMK VRY LGT ICGwinds 300/53 Gusting 64kt.(man this is an awefull metar :s)okay, this metar is just tooo awefull, will take another one, oh ok PGUA 112106Z 09021G32KT 6SM -SHRA SCT005 SCT015 BKN030 BKN060 OVC150 25/24 A2983 RMK WND DATA ESTMD WR//winds 090/21 gusting 31ktsay your Vref30 = 135you'll land at 135+ (1/2 * 21) + (31-21) ?Nope, 135+10,5+10 > 135+20 so you'll be landing at 155IAS(if f.e. the gusts were up to 26, you'd land at 151IASgreetz(ps, this info is sourced from a serious resource)
