On Thursday, May 22, 2008 a customer asked:
Q: I fly the MD-11. Will the HMEC 25-KAP ANR work on aircraft power without the need for batteries?
A:
Not unless the panel has been specifically wired for this headset. Without special / custom avionics work, you would want to look at one of the battery powered models - either the HMEC-25-KA or HMEC-25-KAS (Stereo Version).
