Different headwind T/O speeds.
Hi all.
Am I right in saying that, if you require a T/O speed of say 60kts, and you have a headwind of 10kts, then the groundspeed needed will be 50kts?
If true then what would the g/s need to be if you have a 60kt headwind? (See where I'm coming from?)
I only ask as it's bugged me for ages, plus I am not a pilot!
TIA!
