1.  **PURPOSE.** This advisory circular (AC) contains the Federal
    Aviation Administration (FAA) standards for portable runway and
    taxiway lights and runway end identifier lights for temporary use to
    permit continued aircraft operations while all or part of a runway
    lighting system is inoperative.

2.  **CANCELLATION.** AC 150/5345-50A, *Specification for Portable
    Runway Lights*, dated September 19, 2005, is cancelled.

3.  **PRINCIPAL CHANGES.** The following principal changes have been
    incorporated into this AC:

```{=html}
<!-- -->
```
a.  Revises Table 1, "Photometric Requirements".

b.  Deletes requirement for "Electromagnetic Interference Tests".

c.  Extends the minimum hours for "Battery Operation After Recharge".

d.  Revises the requirements for "Alternative Lighting Devices".

e.  Clarifies "Housing" ground height requirements for airport lighting
    fixtures taller than 14 inches.

f.  Requires that manufacturers offer "Radio Control" an optional
    feature for portable lights.

```{=html}
<!-- -->
```
4.  **CRITERIA FOR USE OF PORTABLE LIGHTS.** Portable lights are for use
    only on a temporary basis and are not suitable for permanent use.
    They are intended primarily for visual flight rules (VFR)
    operations. Where portable edge lights are used to identify the
    runway threshold, they should be supplemented with portable runway
    end identifier lights to improve runway end definition. Portable
    lights must be securely anchored to withstand wind, wake vortices,
    and propeller/jet blasts.

5.  **APPLICATION.** The FAA recommends the guidelines and standards in
    this AC for L-863 Portable Runway and Taxiway Lights. This AC does
    not constitute a regulation and in general is not mandatory.
    However, use of these guidelines is mandatory for L-863 Portable
    Runway and Taxiway Lights funded under Federal grant assistance
    programs. Mandatory terms such as "must" apply only to those who
    purchase L-863 Portable Runway and Taxiway Lights using Airport
    Improvement Program (AIP) or Passenger Facility Charge Program (PFC)
    funds. These standards must be met where lighting systems are
    required for FAA-developed procedures.

6.  **METRIC UNITS.** To promote an orderly transition to metric units,
    this AC includes both English and metric dimensions. The metric
    conversions may not be exact equivalents and, until there is an
    official changeover to the metric system, the English dimensions
    will govern.

### **3.3.2 L-863E Light Unit**. 

The light unit must have a flash rate of 60 to 80 flashes per minute
(fpm) and must meet the minimum photometric requirement of a 20 cd
effective intensity in white light with a beam pattern of 10° degrees
vertical by 30° horizontal for a uni-directional fixture or 360^0^
horizontal for an omni-directional fixture.

**NOTE:** *The effective intensity of a flashing light is equal to the
intensity of a steady-burning (fixed) light of the same color that
produces the same visual range under identical conditions of
observation.*

## **3.4 Electrical**. 

All current carrying parts of the light units must be rated for the
service intended.

### **3.4.1 Non-rechargeable Batteries**. 

Non-rechargeable batteries must be of a readily available type from
multiple sources that will operate the L-863W, L-863W/Y, L-863R/G, ,
L-863Y, L-863R, l-863G, and L-863B lights for a minimum of 72 hours and
the L‑863E lights for a minimum of 24 hours, while maintaining the
photometric requirements in paragraph 3.3.

### **3.4.2 Rechargeable Batteries**. 

a.  Rechargeable batteries must be of a readily available type that will
    power the light fixtures on a full charge for a minimum of 12 hours,
    while maintaining the photometric requirements contained in
    paragraph 3.3.

b.  Fixtures designed to use rechargeable batteries must be equipped
    with voltage monitoring to prevent excessive battery depletion.

#### 3.4.2.1 Battery Operation after Recharge. 

a.  Following operation for at least 8 hours, the batteries must be
    capable of being charged sufficiently, within a maximum of 13 hours,
    to power the fixtures for a minimum of 12 hours.

b.  The batteries must be able to withstand at least 125 total
    charge/discharge cycles.

#### 3.4.2.2 Solar Charged Batteries. 

Solar charged batteries must be of a type that allows for a minimum
equivalent peak of 3 sun hours to maintain operation at full intensity
level and 1.5 sun hours in flashing mode. They must be capable of
powering the lighting units for a minimum of 8 hours of operation.

### **3.4.3 Lamp**. 

a.  The lamp used with the L-863W, L-863W/Y, L-863R/G, L-863Y, L-863R,
    l-863G, and L-863B units must have a rated life of at least 1000

> $$I_{e} = \frac{\left( \int_{t1}^{t2}\text{Idt} \right)}{\left( 0\text{.}2 + \left( t_{{}_{2}} - t_{1} \right) \right)}$$
>
> Where:
>
> I~e~ = Effective intensity (Candela)
>
> I = Instantaneous intensity (Candela)
