Folks,
I'm not good at math.
Have installed the new HUD and well,.....things aren't adding up for me.
I'll let the pictures do the talking for me.
The first one is a page scan from Rod Machado's Private Pilot Handbook.
His instructions for computing TAS don't seem to jive with what I am seeing on screen.
I do note that he says "approximate".
Help !
My mind is spinning !
ps - I used "auto level or wing leveler (whatever its called)" and let the airplane fly for quite a distance over the ocean (MSL) so it settled down as far as speed goes.
