Hi @SimBrief, I just noticed that there is a slight error with the VREF additive calculation using the landing performance tool on the website. When you select the VREF additive option to 1/2 Headwind + Gust, it doesnt set a minimum value of +5kts, per the Boeing AFM (see attached screenshots).

When i select a VREF additive of 1/2 Headwind + Gust, it is giving me a value of 2… when at a minimum it should never be less than 5 and never more than 15 (see screenshots attached) .
-
Likewise, when I select a VREF additive of 1/3 Headwind or gust, it is giving me a value of 1… when it should never be less than 5 and never more than 15 (see screenshots attached).

Is there any chance this can get corrected?
Thank you very much!
