This approach isnt really designed for a straight in landing without circling.
But by the book:
Starting from TYEEE:
-Maintain 8200 until EPLIT, pluss corrections for temperature deviations from ISA(4% per 10deg Celsius below ISA) and possibly altitude corrections for wind, this applies to all altitudes
-After EPLIT you can descend to 7200.
-Passing RESDN, the Final approach fix or FAF, descend to 6500.
-Passing SPREA,descend to 5700
-Passing IPVOV, descend to the MDA 4500ft.
You shall maintain 4500ft until the missed approach point, in this case the RNAV waypoint RWY15.
Now... In real life we never step down from altitude to altitude like this, we do a constant descent.
Why? To keep from having to reconfigure the aircraft or adjusting power, it just makes everything easier.
Which means you need to do some calculations. An optimal, normal descent is 3degrees. You calculate this
by using 300feet per nautical mile as a thumb rule. So for example, in 2NM you should descend 600ft.
To find rate of descend you can use your groundspeed times 5. So 100KTS would be 500ft/min.
Remember the altitude restrictions are minimum altitudes, not maximum. So you don't really have to be at exactly 7200 at RESDN, you could be at 8000 - Just not any lower than 7200.
Also keep in mind that if the wind favors RWY15, and you are 1mile from the threshold at 4500 feet, there is no way you are going to make it in without doing a spin or something.
The elevation is 1624feet, so if you wanna do a constant descent to runway 15, your new missed approach point (Called a VDP, visual descent point), will be when reaching 4500ft(2876ft AGL), divided by 300= at approx 9,5NM. Now this doesnt make sense here, because thats too far away from the field.
Meaning this would need to be a circling approach.
By looking at the profile at the bottom, we can see that by doing stepdowns AFTER the FAF(RESDN), you are descending more than 300ft per NM. Meaning that by using a 300ft/min calculation, we would automatically be above the minimum altitudes at the fixes.
But for this approach, being special, lets do a constant descent from 7200 at the FAF to 4500, ending up at 4500ft overhead the threshold(RWY15 waypoint). That's 2700feet to get rid of. 2700feet divided by 7(2+2+3nm) = 385feet per NM.
Groundspeed(lets say 100kts) divided by 60= 1.66, times gradient(385feet per NM) = A vertical speed of 641
Congratulations, you can now do a stabilized approach from 7200 to 4500,at 100kts GS, at 641VSI without any configuring.
BWT: Circling is only allowed west of the airfield, in this case this will be a left hand circuit (left turn to base, left turn to final).
Let me know if you have any other questions.
