How many edge markers are placed on either side of the MOS threshold and departure ends?

Edge markers mark the boundary areas at the MOS threshold and departure ends, giving a clear visual cue for alignment and clearance from either direction. Placing ten markers on each side provides consistent, highly visible guidance along the entire length of the ends, ensuring operators can quickly verify position and maintain proper clearance. This quantity balances visibility with practicality: too few would leave gaps in visibility and increase the chance of misalignment, while more would add unnecessary clutter without improving guidance. Therefore, ten markers on each side is the standard approach.
