Bae 146 / Avro RJ banshee flap extension noise
Hi all,
Have flown on several 146s / Avro RJs of different ages and all seem to have this weird banshee sound as the flaps extend to the first stage. Is this caused by the disruption of the airflow over the wing or is it the actual noise of the mechanism working away that you might not be able to hear on low-wing aircraft?
Cheers.
