Hey P1949
Just remember these simple gates and the rest will fall into place. Keep it simple. Happy flying, glad your flying in such difficult times. 😎
Draw the following rings from the Runway threshold in the fix page Eg RW25
/120nm
/25nm
/10nm
120nm ring- start descent (works generally for all alts above FL300. If your using the TOD VNAV green circle, see where the ring is in relation to it...gives you a great idea of LNAV track mikes in relation to straight in. Also good for en-route alternates if you have an emergency- you know when to descend just by looking at the ND)
25nm - 10000feet/ reduce to 220kts unless ATC controlled
10nm - 3000 feet 180kts flaps 5.
(if coming downwind abeam the runway aim for 6000ft /220kts abeam) still use the 25nm and 10nm gates.
Use the MCP modes V/S and LVL CHG to achieve these gates. that’s it ....the rest will make sense based around this.
the nice part is if you have weather you see where it is in relation to your approach instantly because it paints over the distance rings and the 220kts allows you to take initial Flaps and gear with ease 👍
