Values
At 11% N1 you are at the acceleration phase. You check your duct pressure, about 30 psi on Standart Sea Level. Then You start the engine and the N2 accelerates to 18% and you see the Oil pressure rising as well as N1.... by 25% N2 you raise the start lever and FF is rising and within 10 seconds EGT responds. You starter cuts out at 55% N2 and then you should see approxiamtly 20% N1, 400 C EGT and 60% N2. That is called a stabelized condition. If you are at a higher elevation, 5000 feet, then your N2 shows 25% about. I hope this helps for the CFM 56.
