Hi everyone,
a doubt raised while reviewing GS Mini function and headwind effect on IAS: as far as I know an increase in headwind would cause the speed trend (IAS) to go up, but only if no vertical acceleration's allowed with increasing lift (no altitude change). This way, the energy coming from HW, is converted into a horizontal acceleration (IAS increase). At that point I was asking myself if there was any other effect (beyond "inertia" and compressibility) acting on the pitot tube reading with increasing headwind, my belief is ... the greater the headwind, the faster the quantity of ram air impacting the tube, the higher the IAS reading, am I right ?!
Every answer's widely appreciated,
