Question 2

HRS Bar

Answer 2

Horizon Reference System (HRS) (when installed) shall be
utilized for single-spot ship operations. A visible horizon may be obtained through the use of NVDs and must be
the same devices that would be used by the aircrew in flight

Question 3

Line up Lights

Answer 3

Steady /Medium for NVD OPS

Question 4

Drop Light(s)

Answer 4

Red
OFF for NVD Ops

Question 5

Deck Edge Lights

Question 6

Deck Status Lights

Answer 6

Dim or OFF for NVDs

Question 7

Navigation Lights

Answer 7

Dim or OFF for NVDS

Question 8

Stern Light

Answer 8

Off for NVD Ops

Question 9

Acceptable Lighting Degradations (Aided vs. Unaided)

Answer 9

Permissible Lighting Equipment Degradations — Unaided Operations
Night unaided VMC operations may be conducted in the event of a failure of not more than one of the lighting
subsystems required for ship’s facility certification provided the following criteria are met:
1. A visible horizon exists and is discernible by the aircraft commander in the shipboard landing/takeoff
environment.
2. The ship’s Commanding Officer and embarked Air Detachment Officer in Charge (aircraft commander for
non-embarked evolutions) concur that the failed lighting system is not critical to the scheduled mission.
Permissible Lighting Equipment Degradations — Aided (NVD) Operations
Aided operations may be conducted in the event of a failure of more than one of the lighting subsystems required
for ship’s facility certification provided all of the following criteria are met:
1. A visible horizon exists and is discernible through NVDs by the aircraft commander in the shipboard
landing/takeoff environment.
2. The ship’s commanding officer and embarked Air Detachment Officer in Charge (aircraft commander for
non-embarked evolutions) concur that the failed lighting systems are not critical to the scheduled mission.
3. The following lighting subsystems remain operational and available:
a. Overhead/Forward Structure Floodlights.
b. Deck Surface/Hangar Wash Floodlights.
c. Associated Lighting Control Panels.

Question 11

Flight Deck Markings

Answer 11

When properly used, flight deck markings ensure adequate obstruction clearance and proper positioning for
the specific aviation evolution being conducted. The information herein is intended as a quick reference for
common deck markings. Specific dimensions can be found in the current Air-Capable Ships Aviation Facilities
Bulletin No. 1 and Shipboard Aviation Facilities Resume (NAEC-ENG-7576). Deck markings are illustrated in
Figures 2-1 and 2-2.
2.6.1 Landing Lineup Line and Circle
(Refer to Figure 2-1.) Obstruction clearance is ensured when the aircraft for which the facility is certified lands
with the main mounts (tail wheel aircraft), nosewheel, or forward skid cross tube within the landing circle and the
fuselage centerline aligned with the landing lineup line.
2.6.2 Vertical Replenishment “T” Line
(Refer to Figure 2-2.) Obstacle clearance is ensured when the aircraft for which the facility is certified hovers with
its rotor hub(s) on or aft of the line. This statement also applies to V-22 for a single “T.” Where two “T” lines are
encountered with the “T’s” pointed toward each other, clearance is ensured when the rotor hub(s) or V-22 centerline
are between the two lines. The “T” line is for use with H-1, H-57, H-60, and H-65 series helicopters.
2.6.3 Vertical Replenishment Ball and “T” Line
(Refer to Figure 2-2.) This line will only appear in combination with a “T” line when the “T” line does not provide
enough clearance for larger rotor aircraft. Unless otherwise noted, the ball and “T” line provide clearance for the
H-53 and V-22 series aircraft when the aircraft hover with main and/or tail rotor hubs over or aft of the line.
2.6.4 Vertical Replenishment Dash Line
(Refer to Figures 2-2 and 2-3.) Obstacle clearance is ensured only when the aircraft for which the facility is certified
hovers with the centerline of the aircraft aligned directly over the line. An obstacle-free approach is ensured only
when the approach is made along the dashed line.
2.6.5 Helicopter In-Flight Refueling Marking
(Refer to Figure 2-2.) The HIFR hose pickup point is located on the port side and is designated with a letter “H.”
Obstacle clearance is ensured when the helicopter for which the facility is certified hovers oriented fore and aft with
the hoisting point over the “H” for hose pickup.
