b) Where operations are conducted in accordance with 5.4.1.7 b) and c) and 5.4.1.8, average sign luminance shall be at least: Red 10 cd/m2 Yellow 50 cd/m2 White 100 cd/m2 Note.— In runway visual range conditions less than a value of 400 m, there will be some degradation in the performance of signs. 5. The luminance ratio between red and white elements of a mandatory sign shall be between 1:5 and 1:10. 6. The average luminance of the sign is calculated by establishing grid points as shown in Figure A4-1 and using the luminance values measured at all grid points located within the rectangle representing the sign. 7. The average value is the arithmetic average of the luminance values measured at all considered grid points. Note.— Guidance on measuring the average luminance of a sign is contained in the Aerodrome Design Manual, Part 4. 8. The ratio between luminance values of adjacent grid points shall not exceed 1.5:1. For areas on the sign face where the grid spacing is 7.5 cm, the ratio between luminance values of adjacent grid points shall not exceed 1.25:1. The ratio between the maximum and minimum luminance value over the whole sign face shall not exceed 5:1. 9. The forms of characters, i.e. letters, numbers, arrows and symbols, shall conform to those shown in Figure A4-2. The width of characters and the space between individual characters shall be determined as indicated in Table A4-1. 10. The face height of signs shall be as follows: Legend height Face height (min) 200 mm 400 mm 300 mm 600 mm 400 mm 800 mm Runway code number Minimum character height Mandatory instruction sign Information sign Runway exit and runway vacated signs Other signs 1 or 2 300 mm 300 mm 200 mm 3 or 4 400 mm 400 mm 300 mm 2007/70/II. szám Annex 14 — Aerodromes Volume I 25/11/04 APP 4-2 11. The face width of signs shall be determined using Figure A4-3 except that, where a mandatory instruction sign is provided on one side of a taxiway only, the face width shall not be less than:
