ALS | Approach Light System |
HAT | Decision Height expressed as height above Touch-down Zone (TDZ) |
DH RA | Decision Height expressed as a Radio Altimeter reading |
OCL | Obstacle Clearance Limit |
HIRL | High Intensity Runway Lights |
ILSC | Minima applicable to an auto-coupled ILS approach (landing performed manually) |
ILSC x | As above, but ILS glide path unsuitable for use below Decision Height because it gives insufficient wheel clearance (less than 28 ft) over the threshold |

RVR | Runway Visual Range. Visibility along the runway measured by a human observer, or transmitter with associated computer, and taking into account visual aids, background brightness etc. |
RVV | Runway Visibility Value. A less precise measurement than RVR, applying in the USA only. In certain circumstances expresses visibility in sixteenths of a mile instead of feet. |
