Term
COMPRESSOR STALL
What needs to be done if you have a compressor stall? |
|
Definition
| 1. Retard thrust levers to idle to clear the stall monitor EGT and N2 percent rpm decrease. 2. Advance the thrust lever slowly to determine if stall will reoccur. If stall does not reoccur and parameters indicate normal, continue engine operation. 3. If stall reoccurs the engine should be shutdown. Record where stall occurred (i.e. N1,N2, OAT) |

How can a hung start be detected and what are the emergency procedures? |
|
Definition
| Can be recognized by an abnormally slow acceleration and N1, N2 decreasing or stabilizing below normal idle. Check EGT if EGT is low attempt to increase starter air pressure if this is not possible or has no effect set start lever to cutoff and motor for 60 seconds to clear any residue fuel |
