Synchronising DI
Here's a "what if" question for you all :
It's time for the FREDA check, however your leg appears to have taken you through an area of turbulence (light/mild) which there appears to be no end to (you've been flying through it for a good few minutes and there's still no sign of it clearing up). Assume VFR (vis. CAVOK, flying below the dense cloud cover).
How do you go about synchronising the DI ?
