(2) Operating requirements. Portable
oxygen concentrators that satisfy the
acceptance criteria identified in paragraph (f)(1) of this section may be carried on or operated by a passenger on
board an aircraft provided the aircraft
operator ensures that all of the conditions in this paragraph (f)(2) are satisfied:
(i) Exit seats. No person operating a
portable oxygen concentrator is permitted to occupy an exit seat.
(ii) Stowage of device. During movement on the surface, takeoff and landing, the device must be stowed under
the seat in front of the user, or in another approved stowage location so
that it does not block the aisle way or
the entryway to the row. If the device

is to be operated by the user, it must
be operated only at a seat location that
does not restrict any passenger-s access
to, or use of, any required emergency
or regular exit, or the aisle(s) in the
passenger compartment.

Section 135.93 Minimum altitudes for use of
autopilot.
(a) Definitions. For purpose of this
section - 
(1) Altitudes for takeoff/initial climb
and go-around/missed approach are defined as above the airport elevation.
(2) Altitudes for enroute operations
are defined as above terrain elevation.
(3) Altitudes for approach are defined
as above the touchdown zone elevation
(TDZE), unless the altitude is specifically in reference to DA (H) or MDA, in
which case the altitude is defined by
reference to the DA(H) or MDA itself.
(b) Takeoff and initial climb. No person
may use an autopilot for takeoff or initial climb below the higher of 500 feet
or an altitude that is no lower than
twice the altitude loss specified in the
Airplane Flight Manual (AFM), except
as follows - 
(1) At a minimum engagement altitude specified in the AFM; or
(2) At an altitude specified by the Administrator, whichever is greater.
(c) Enroute. No person may use an
autopilot enroute, including climb and
descent, below the following - 
(1) 500 feet;
(2) At an altitude that is no lower
than twice the altitude loss specified in
the AFM for an autopilot malfunction
in cruise conditions; or
(3) At an altitude specified by the Administrator, whichever is greater.
(d) Approach. No person may use an
autopilot at an altitude lower than 50
feet below the DA(H) or MDA for the
instrument procedure being flown, except as follows - 
(1) For autopilots with an AFM specified altitude loss for approach operations - 
(i) An altitude no lower than twice
the specified altitude loss if higher
than 50 feet below the MDA or DA(H);
