A runway report consists of eight digits in five groups (R R R R E R C R e R e R B R B R ) with the following interpretation: R R R R Runway designator. The numerical identifier of the runway in question. 88 means all runways, 99 indicates repetition of previous report. If there are two parallel runways, the right one is indicated by adding 50 to its number. For example, runway 04L (or 04) is denoted by 04, whereas 54 means runway 04R.
