The stripes shall be 4 inches (0.10 m) wide, and shall be painted at an angle of approximately 45 degrees rising from port to starboard. In addition, alignment stripes shall also be painted on hangar doors that, when fully retracted as designed, leave visible yellow/red stripes at the top of the doorway, yet still provide sufficient clearance for aircraft movement into/out of the hangar. With the hangar door fully retracted, the alignment stripes shall be painted in the upper corners of the doorway, on the door (exterior and interior), and on the adjacent track/bulkhead. The alignment stripes shall be readily visible from the deck, and should be approximately 6 inches (0.15m) long and 2 inches (0.05m) wide.”

This will create an apparent 12-inch wide white extension of the approach line, up the white forward structure/hangar face for proper pilot alignment.”

3.4 Lubrication. The Contractor shall lubricate Helo Hanger Door Assembly (i.e. Port and Starboard) components in accordance with Table 2.1 of the TP 7181.
