The term "certified" can take on many meanings. It is best to review with the
appropriate OEM manager and business development manager for the aircraft
or airline in question to get the latest status. Keep in mind, the headset is TSO
certified and has been tested on many di erent aircraft. Approval to use the
headset on any specific aircraft can vary by the type of operation the headset
will be used in, by country and even by the aircraft certification organizations.
Depending on your needs, Bose can assist in getting the appropriate approvals
you may require.
It's a good idea to have extra sets of earbuds available to pilots or stored in
aircraft. If extra tips are stored on aircraft where multiple pilots will use the
headset, it is good to plan on making medium tips available as this size
should fit the majority of the pilot population.
You asked, and we listened. The ProFlight Series 2 cable is thinner and more
flexible than the original ProFlight cable.
The headset is required by TSO to output up to 110dB. All aviation headsets
we have tested to date provide this level of output.
These earbuds don't create a strong seal and in fact, even with a
less-than-perfect fit, the earbuds provide great noise reduction.
Yes. The ProFlight Series 2 did not replace the A20 Aviation Headset. It is
designed to meet the unique needs of pilots and crew who fly pressurized and
crewed aircraft, which are typically less noisy.
The ProFlight Series 2 does not have as much total noise reduction
as the A20 Aviation Headset.
