Could you please explain to an old F/E who is not supposed to know anything about this nav thing but from the chart how do you know when to start the proceedure turn. Without a basic time setting how can adjust for a varying tailwind so as to arrive at an accurate turn.
All ADFs I remember
1] You time from overhead the fix outbound adjusting for wind to
determine the point to start the proceedure turn [basic time given
on chart]
2] Time the leg of the proceedure turn either 45degs or 30 degs again
adjusting for wind start to start turn
3] If you have guessed it all OK then you will be at the correct
height, the correct geographical position and aligned with the fix
when turn complete
4] You again time inbound from fix for missed approach point
Now that is how I remember it with no INS or DME, but the memory might be failing me
