| |4.3 | EGT Divergence Calculation | | |
| | | | | |
| |4.3.1 | EGTdiv = EGTdiff - deltaEGTref | | |
| | | deltaEGTref is calculated if the A/C has| | |
| | | entered PH 5.1 and PH6 from each flight | | |
| | | leg. | | |
| | | deltaEGTref PH 5.1 | | |
| | | DMU | | |
| | | deltaEGTref PH 6 | | |
| | | DMU | | |
| | | | | |
| | | The deltaEGTref is represented in mathe-| | |
| | | matical from as below: | | |
| |4.3.2 | CEGT#1 = EGT#1 + (N1#2 - N1#1) * C09.1 | | |
| |4.3.3 | EGTdiff = CEGT#1 - EGT#2 | | |
| |4.3.4 | this calculation is done 'M' consecutive| | |
| | | times once per second i.e. during 10 sec| | |
| | | | | |

| |4.3.5 | deltaEGTref = deltaEGTref-1 + 1/K+1 * | | |
| | | (deltaEGTm - deltaEGTref-1)| | |
| | | The calculation deltaEGTref is stored | | |
| | | and used for the EGTdiv calculation | | |
| | | (item 4.3.1). | | |
| | | deltaEGTref-1 is the deltaEGTref value | | |
| | | from previous flight. | | |
| | | After the deltaEGTref calculation the | | |
| | | following EGTdiff calculation is per-| | |
| | | formed. | | |
| | | CEGT#1 = EGT#1 + (N1#2 - N1#1) * C09.1 | | |
| | | EGTdiff= CEGT#1 - EGT#2 | | |
| | | EGTdiff is calculated from the actual | | |
| | | valve of EGTdiff and the stored delta | | |
| | | EGTref value. | | |
