Restricted Area Is an airspace of defined dimensions above the land areas or territorial waters of s State, within which the flight of aircraft is restricted in accordance with specific conditions. In the context of the FUA Concept, some Restricted Areas are subject to management and allocation at Level 2 are established at Level 1 as "AMC-manageable areas" and identified as such in AIP. Restriction of Range A situation in which the variability of data in a sample is less than the variability in the population from which the sample has been drawn. (SIOP, 1987). Retroactive / Proactive Interference If you learn two series of information (e.g. two series of words) one after the other, the second series might inhibit the memorisation of the first one (retroactive interference). Also, the first series might have an inhibitory influence on the memorisation of the second series (proactive interference). Review of the General Concept of Separation Panel This panel completed guidance material for the Required Navigation Performance (RNP) scheduled for publication as an ICAO manual. The meeting further established a set of RNP types for en-route operations. The panel developed provisions for an RNAV longitudinal distance-based separation minimum as well as guidance material on protected airspace. Further work is planned on RNP operations, RNAV separation in Automatic Dependent Surveillance ADS environment as well as airspace planning methodology. Ring around The continuous reception of aircraft replies to interrogations by the side lobes of the ground antenna. This normally occurs only at short ranges, usually due to the non-existence of a side lobe suppression mechanism or the improper functioning of this mechanism at either the interrogator or the transponder side. Ring-Laser Gyro A gyroscope based and a laser beam instead of a rotating mass, providing the same data as a gyroscope. Risk The probability of negative consequences of relying on the machine to support successful completion of the tasks. Risk Analysis A complex study technique used to evaluate risks and to analyse how far forecasts might go wrong - and at what cost. Risk Control Responses to changes in risk over the course of a project by executing a risk management plan. Risk Identification Determination of the likely sources of risk and the magnitude of that risk. Risk Management A management plan to be implemented under risk control. This is modified by the outputs of the risk control procedures. Risk Simulation A method of analysing and assessing (usually by computer) particular aspects of a project. RMS (OR) The RMS value of the state errors for a certain Mode Of Flight as function of the time spent in that Mode Of Flight, averaged over a certain number of Trajectories (OR means Outliers removed).

The RMS value of the state errors at the moment of Track Recovery or Start, averaged over a certain number of Trajectories.
