'''Line of Sight''' (LoS) is a stat that will indirectly affect several mechanics, being:
* [[#Effective Line of Sight|Effective Line of Sight]] for map [[routing]],
* [[#Detection|Detection]] success rate,
* [[#Contact|Contact]] trigger rate, for airstrike damage,
* [[#LBAS LoS|Reconnaissance Defense Bonus]] for LBAS Defense Fighter-Power,
* [[#Artillery Spotting|Artillery Spotting]] trigger rate.
For details on the LoS {{LOS}} stat growth please see ''[[Stats#Stat Growth|Stats]]''.
=Effective Line of Sight=
"'''Effective Line of Sight'''" (ELoS, also called "Fleet LoS") is the Line of Sight (LoS) that affect certain maps' [[routing]]. Certain branching requirements in sorties are affected by the LoS of the entire fleet, this total LoS following unintuitive behaviors.
*As a general rule: '''equipment LoS is more impactful than ship LoS''' when determining ELoS.
==Formula 33==
The Formula 33, sometimes referred to as F33, is the most accurate "Fleet LoS" calculation formula known. It is described as follows<ref>http://ja.kancolle.wikia.com/wiki/%E3%83%9E%E3%83%83%E3%83%97%E7%B4%A2%E6%95%B5</ref>:
{{Formula
|Title=LoS Formula 33
|Math= \text{LoS}_\text{Fleet} = \sum_{\text{All Ships} } \sqrt{LoS_\text{Ship} } + C_{n} \times \sum_{\text{All Equipment} } C_{e} \times ( \text{LoS}_{e} + C_{\star} \times \sqrt{\bigstar} ) - \lceil Q \times Lv_\text{HQ} \rceil + 2M
|Var=<math>\text{LoS}_\text{Ship}</math> the ship's base LoS {{LOS}}.
**Total LoS {{LOS}} of [[Visible Fit Bonuses]] should be added to this part, unlike equipment improvement bonuses.
*<math>C_{n}</math> the Node factor, it represents the weighting of the formula that is '''known to vary''' across different maps and nodes (''see [[#Estimated LoS|below]]''),
*<math>C_{e}</math> the equipment multiplier (''see [[#Equipment Types|below]]''),
*<math>LoS_{e}</math> the equipment's base LoS {{LOS}}, excluding visible fit bonus,
*<math>C_{\star}</math> is the [[improvement]] modifier of the equipment (''see [[#Equipment Types|below]]''),
*<math>\bigstar</math> the equipment's [[improvement]] {{Star}} level,
*<math>Q</math> the HQ level modifier, varying depending on the map:
** '''0.35''' on [[5-2]] and [[6-3]].
** '''0.4''' otherwise.
*<math>Lv_\text{HQ}</math> the [[HQ]] level.
*<math>M</math> the number of empty ship slots in the fleet:
**'''0''' for 6 ships fleet,
**'''+1''' increase per missing ship,
***This value can increase mid-sortie if a ship is ''sunk'' or ''[[Evacuation|evacuated]]''.
**'''-1''' for a full [[Striking Force Fleet]] (7 ships).
|Notes=Equipment LoS weight more than ship LoS.

==Equipment LoS Weighting Modifier==
The node factor <math>C_{n}</math> affects the weighting of equipment LoS.
* It depends on the map (''see the [[#Estimated LoS|below]]'').
The equipment and improvement multiplier <math>C_{e}</math> and <math>C_{\star}</math> will affect the "real" LoS given per equipment.
* It depends on the equipment type (''see the [[#Equipment Types|below]]'').
Because of those factors:
*Some equipment are more efficient to provide LoS,
*Ship LoS is less relevant, notably in maps with higher node factors.

===Events===
In [[events]], LoS cheks are also performed following the same rules, but will additionally vary with difficulties, higher difficulties recruiting higher LoS.
===FAQ===
'''Q: Why do I keep getting offrouted?'''
'''Q: Why do I keep getting offrouted?'''
'''A:''' Planes that are wiped out no longer contribute to LoS. If you were depending on bombers to hit the LoS threshold, you can fall under the threshold when encountering heavy enemy anti-air.

=Detection=
{{details|Detection}}
At the start of any [[Day Battle]], "detection" will be attempted by the fleet. Detection is required to take part in the [[Aerial Combat]] phase.
Only the Ship's LoS and the LoS from the participating planes is taken into account for the trigger rate:
* {{Carrier Recon}}{{Large Recon}} [[Carrier Recon]]s,
* {{SPR}}/{{Night Recon}} [[Seaplane Recon]]s,
* {{SPB}}/{{Night SPB}} [[Seaplane Bomber]]s,
* {{LFB}} {{Equipment/Link|Type 2 Large Flying Boat|PBY-5A Catalina|text=Large Flying Boats|link_category=Large Flying Boat}}.
=Contact=
{{details|Contact}}
At the start of any [[Airstrike]] phase, "contact" may be triggered, increasing the airstrike power if triggered.
Only the LoS from the participating planes is taken into account for the trigger rate (step 1):
* {{Carrier Recon}}{{Large Recon}} [[Carrier Recon]]s,
* {{SPR}}/{{Night Recon}} [[Seaplane Recon]]s,
* {{LFB}} {{Equipment/Link|Type 2 Large Flying Boat|PBY-5A Catalina|text=Large Flying Boats|link_category=Large Flying Boats}},
Only the LoS from the participating planes is taken into account for the plane selection (step 2):
* {{Carrier Recon}}{{Large Recon}} [[Carrier Recon]]s,
* {{SPR}}/{{Night Recon}} [[Seaplane Recon]]s,
* {{LFB}} {{Equipment/Link|Type 2 Large Flying Boat|PBY-5A Catalina|text=Large Flying Boats|link_category=Large Flying Boats}},
* {{Torpedo Bomber}}/{{Night Torpedo Bomber}} [[Torpedo Bomber]]s.
=LBAS LoS=
{{details|LBAS#Defense Fighter-Power|l1=LBAS Defense Fighter-Power}}
Unlike ship mechanics, [[LBAS]] do not need/utilize the LoS stat and so this stat is mostly useless.
The only use for LoS is for "[[LBAS#Defense Fighter-Power|Defense Fighter-Power]]" in air defense mode, where it determines the "Reconnaissance Defense Bonus" (<math>\text{Mod}_\text{recon}</math>) for {{SPR}} [[Seaplane Recon]]s, {{LFB}} [[Large Flying Boat]]s, {{Carrier Recon}} [[Carrier Recon]]s, and {{LB Recon}} [[Land-based Recon]]s:

The LoS on all other aircraft or in other LBAS modes is not counted.
=Artillery Spotting=
{{details|Artillery Spotting}}
Artillery Spotting attacks require the use of recons/bombers.
Only the Ship's LoS and the LoS from the participating planes is taken into account for the trigger rate:
* {{SPR}}/{{Night Recon}} [[Seaplane Recon]]s,
* {{SPB}}/{{Night SPB}} [[Seaplane Bomber]]s,
* {{Torpedo Bomber}}/{{Night Torpedo Bomber}} [[Torpedo Bomber]]s,
* {{Dive Bomber}} [[Dive Bomber]]s.
