RTOW chart with no Tailwind correction

Mon Mar 30, 2020 1:35 am

Hi folks,

I have question to ask. What would be the Tailwind correction for A320 for take-off speeds if the RTOW chart doesn't have a Tailwind correction???

I have 2 RTOW charts for 2 different airports. 1 RTOW chart has the Tailwind correction (i.e Tailwind -5, -10) while the other RTOW chart doesn't as it only has the Headwind correction on the bottom of the chart. Is there a sort of Rule of Thumb for that??

I’m guessing here, but I don’t believe downwind take-off is authorized. It wouldn’t be under my regulator, no data, no go.

wxman11,

GalaxyFlyer’s response above is correct for the Airbus A-320.

There is no rule of thumb.

If your takeoff data specifically does not provide numbers for a tailwind takeoff (-5, -10, etc), then takeoff with any amount of tailwind would be prohibited. Whether or not takeoff with a tailwind is allowed is influenced by many factors—aircraft gross weight and multiple environmental variables, such as airport elevation, outside air temperature, runway length, runway condition, terrain, obstacles surrounding the airport, etc.

Without seeing the charts it’s hard to say, there is such a thing as a quick check chart on the Airbus, it looks a bit like an RTOW chart however are not as accurate meaning you will end up leaving payload behind.
