Is it possible for an OK4 Green?

Just curious as I have seen OK 4 on every greenie board I have seen.

OK is definitely possible.
OK is not implemented, but that's also quite a reserved grade as far as I understand it.

Just a heads up.
I am in the process of overhauling the entire final grade calculations.
The comments seem quite alright now, so I can now better proceed with the final grade.
Hopefully they'll get more accurate.
I'll update this forum name and update it as we go

Final Grades

Thanks again!

@zenith bloom A trap like this I would think would have been an example of an OK 4. instead of an (OK) 4. Or I'm misenterpreting the grading?

I think it'd be best to discuss specifics once the new algoritm is in 🙂

But I'll put a few assumptions about the grading I've picked up during reading all the docs down here.
Mostly so later on we can reference my assumptions again, if I at all made any wrong ones

  1. OK (4points) is the highest attainable grade outside of emergencies or special occasions.
  2. OK is given when there is no mistake made other than some minor corrected ones.
  3. (OK) (3 points) is a very decent grade and the one I see very often in documentation and examples of old performance charts.
    Meaning that (OK) is achieved very often by actual professionals landing. Which means OK is even not as easy for them as (OK).

In any case. I'll be reviewing a lot of the traps and documentation
This might very likely turn out to be OK, indeed

@zenith bloom Thanks for the feedback! I thought the -OK- (perfect) is a five point award, OK a minor deviations and good correction for 4 and (OK) one or more safe deviations for 3. Also an OK 3 would be graded a 4 but an OK 4 would be graded a 3.5 unless deck or weather conditions were at play. Hopefully someone else could chime in. Unfortunately the LSO natops manual does not go into grading detail which is covered in manuals that I dont have access to.

This is from a document written for DCS by an ex-18 pilot.

But yes, if anyone can confirm/deny it would help

#

When looking at greenieboard examples there isn't any OK in the legend, which might indicate it is not used often enough after all

#

(also good to note that the grading system is pretty subjective)

@zenith bloom I absolutely agree regarding the OK underlined Pass everything I have read states this is considered a perfect pass in deteriorating conditions.

What I am referring to is that from what I have read you can get an OK pass trapping a 4 wire which currently doesn't seem possible with current grading modeled. Thats why I provided that graph. The only writeup is a (LUL)X which is a minor deviation corrected well before in close which meets the criteria for an OK pass.

As it stands now it seems the only trappable wire to produce an OK pass would be the 3 wire. Using this example which displays the trend analysis from the APARTS Trend Analysis in NATOPS, even an OK 2 Green pass is plausible. As well as an (OK) 1 wire.

I know this is rather subjective, but I do believe a compromise to get closer to whats more natural would be that OK 4 wires should be achievable provided there were no control errors and only minimal deviations with good corrections. Apologies for any confusion.

For anyone who's reading this.

This is the current (and updated) assumptions and understanding of a final grade as I understood it from anecdotes and documentation.
This forum post is to discuss and understand it all together.
Please keep it clean, but don't hesitate to challenge thoughts and ask anything.

This message is pinned for reference and will be updated as my understanding changes.
This is what eventually will be put into the algorithm (very soon).

Final grades:

OK
  Minimal to no comments. 
  1. Normal comment at X corrected IM
  2. Normal comment at X corrected to minor at IM and no comment at IC
  3. Can be OK with 2,3 or 4 wire if no H or LO comments were detected. (1 wire would mean either settling or being to low at the ramp already).
  4. No major comments allowed. (those are pretty big deviations at the current rate)
  5. A very minor offset (straight line from groove start)
  
 (OK)
  1. a single minor AW comments (IC, IM, X)
  2. any minor|normal comments that are corrected at the next stage. (IM, IC) (X would still be OK)
  3. A 1 wire
  X. Any major comments IC would lead to a NG
  
 --- 
  1. Any Major comments that do not lead to a CUT (major comments are hard to get)
  2. LL|LR IW (automatic downgrade NG)
  3. LO IC (automatic downgrade to NG)
  6. __NESA__. A groovetime that's way too short, would normally lead to a WO anyway
  7. __OS__ An extreme overshot of the groove would normally lead to a WO.     
 
 C 
  1. Very H|LO AR
  2. Very L|R AR
  3. Very LL|LR IW
  4. Groove start outside the groove cone. (Should lead to a waveoff, but in case someone commits)
