Marco1-11 Posted September 27, 2020 Posted September 27, 2020 I'm new to the Harrier, my problem is the annoying irregular igniter crackling sound always kicks in at around 9.2 RPM. It disappears once the engine has spooled up and everything is fine afterwards. I've tried APU/Gen starts but the problem remains. Has anyone experienced this? I thought the AV-8B was a straightforward cold start, so it has to be me right? Cheers
Captain Orso Posted September 28, 2020 Posted September 28, 2020 This is completely WAD. Once the engine has been spooled up through the APU and the igniters are sparking, you still must advance the throttle from STOP to IDLE for the engine to start.

Marsvinet Posted September 28, 2020 Posted September 28, 2020 You are supposed to hear the igniters at that point, since the engine needs that initial spark to ignite the combusting section of the engine to become self-sustaining. How loud they should be compared to the engine at that point, I don't know but they should be running.
RAZBAM_ELMO Posted September 29, 2020 Posted September 29, 2020 This is a feature of the Harrier and is implemented correctly. Know and use all the capabilities in your airplane. If you don't, sooner or later, some guy who does use them all will kick your ass. — Dave 'Preacher' Pace, USN.
