8. CRUISE.As we level off at FL280, pick up the check list and look at this table. A little it down we find the figures for FL 280. Weight around 44t, IAS 284 and EPR 1.80. The EPR is only approximate, it will vary with temp and center of gravity. An aircraft on this level will fly along the 1013 pressure-level and that will go a little bit up and down. This will also make the aircraft climb and descent some. Remember, there is no autothrottle to be used in the Classic. ATIS. Before reaching the TOD (Top OF Descent), check the ATIS for ESGG. ESGG information BRAVO. Runway in use 03 wind 350/10 RVR300/200/200 visibility 100m clouds broken at 100ft, QNH 1014 Low Visibility Procedures in force. We need 300m for CATII, the second value is for guidance. The low vis procedures means that we can expect CATII to be in use. Also check ESGJ and EKYT atis, just to be sure they are still opened. TOD. Time to start our descend. Check list contains a descent table. 92 miles in still air. In this kind of weather it is always nice to be a little low in descent, so do not stay up there to long. DESCENT CHECK LIST
APPROACH EPR/SPEEDS. Normal GO AROUND EPR will be set on the bug in the EPR-instrument. This will differ somewhat with temperature and airport elevation, but 2.02 in the normal value. Check the speed book to get the different approach speeds. We have used 2 000kg fuel, landing weight will be 43 ton. Speed to be set on the bug - 130. |
