Hi, I was setting up a flight EDDM to LIRF from RW26R via TURB6N SID, cruise altitude FL290. TOW and all parameters were within operational l limits. PERF page and TAKE OFF page correctly filled. However, VNAV did set the speeds at ALL waypoints to 250 on the LEGS page and did not calculate the intermediate altitudes properly, in fact it did not even consider the cruise altitude as entered in the PERF page and calculated odd FL around FL240. I managed to reach cruise altitude by using SPD and FLCH. When I reached cruise altitude, EICAS switched to CRZ and the correct cruise parameters (speed and altitude) showed up on the LEGS page. VNAV descent and landing were flawless. Any thoughts on the VNAV CLB calculation? Thanks
