Coverage
The Pilot’s Operating Handbook (POH), found in the airplane at the time of delivery from Pipistrel,
contains information applicable to the ALPHA Electro airplane and to the airframe designated by the
serial number and registration number shown on the title page. All information is based on data avail-
able at the time of publication.
This POH consists of nine sections that cover all operational aspects of a standard equipped airplane.
Section 9 contains the supplements which provide amended operating procedures, performance
data and other necessary information for those airplanes that conduct special operations and/or are
equipped with both standard and optional equipment. Additional supplements are individual docu-
ments which are issued/revised separately. The log of effective pages should be used to determine the
status of each supplement.
Revision tracking, filing and identifying
Pages to be removed or replaced in the Pilot’s Operating Handbook are determined by the log of
effective pages located in this section. This log contains the page number and revision number for
each page within the POH. As revisions to the POH occur, the revision number on the effected pages
is updated. When two pages display the same page number, the page with the latest revision shall be
used in the POH. The revision number on the log of effective pages shall also coincide with the revi-
sion number of the page in question. As an alternative to removing and/or replacing individual pages,
the owner can also print out a whole new manual in its current form, which is always available from
www.pipistrel-aircraft.com.
Revised material is marked with a vertical bar that will extend the full length of deleted, new, or re-
vised text added to new or previously existing pages. This marker will be located adjacent to the ap-
plicable text in the margin on the outer side of the page. The same system applies when the header,
figure, or any other element inside this POH is revised. A list of revisions is located at the beginning of
the log of effective pages. Pipistrel is not responsible for technical changes/updates to OEM manuals
supplied with the aircraft (eg. radio, transponder, GPS, etc.).
Warnings, cautions and notes
Safety definitions used in the manual:
WARNING! Disregarding the following instructions leads to severe deterioration of flight
safety and hazardous situations, including such resulting in injury and loss of life.
CAUTION! Disregarding the following instructions leads to serious deterioration of flight
safety.
NOTE An operating procedure, technique, etc., which is considered essential to emphasize.
