b) a radial expansion is possible with a slight relaxation of the vertical error budget to 4.9 m (16 ft). This relaxation is still very conservative and equates to 66 per cent of the equivalent ILS error budget [7 m (24.1 ft)]. ATT G-41 23/11/06 2007/70/II. szám Annex 10 — Aeronautical Communications Volume I 13.7.6.2 An example of the use of Figure G-33 is presented by point A. Using the foregoing expansions, a computed centre line approach to a secondary runway is possible for a –1 400 m runway spacing and +200 m threshold stagger. 14. Application of Table G-15 service level ob ectives for MLS/RNAV operations 14.1 MLS/RNAV procedures discussed below can be conducted with ground equipment meeting integrity and continuity of service objectives identified in Table G-15. Many of these operations may be accomplished with MLS ground equipment meeting Level 2 objectives only. Further a majority of the procedures may not require positive guidance during the discontinued approach/missed approach procedure. Where procedural means cannot provide the required obstacle clearance along an unguided discontinued approach/missed approach, some form of secondary guidance will be required. The accuracy requirements of the secondary guidance system will be determined by the nature of the obstacle-rich environment. 14.1.1 In those rare cases where an MLS/RNAV procedure is in an obstacle-rich environment, the calculated obstacle exposure time (OET) may require a higher level of equipment type than that required for landing. 14.1.2 etermination of critical segments 14.1.2.1 The following terms are used to determine the length of the critical segments of an MLS/RNAV procedure. Obstacle-rich environment. An environment where it is not possible to construct an unguided discontinued approach/missed approach using procedural means. Secondary guidance will be required to achieve a climb to minimum sector altitude. Critical segment. A segment where an unguided discontinued approach/missed approach would expose the aircraft to an obstacle. Obstacle exposure time (OET). The time interval required to fly the critical segment of an MLS/RNAV procedure. This time is used to establish the required level of service of the non-aircraft guidance equipment. 14.1.2.2 In order to determine OET the following procedure can be followed (see Figure G-34):
