Does that include 'if there is a significant headwind component', or should you just stick to the Law and leave flight training alone?
You are
absolutely correct Trent 972 and I realise the error of my ways.
Everybody: The IAS for lowest drag depends on ‘headwind’, as does the best glide speed.
So, if you need maximum range while flying
into a significant headwind the IAS for minimum drag will be different from nil wind conditions. I always thought that aircraft spend most of their cruise time in a 'headwind' (that's blowing at about the TAS), but Trent 972 obviously knows better. Trent 972 will now explain how to calculate the maximum range IAS, taking into consideration 'headwind'.
Over to you, Trent…
