Cessna 208B - Maximum Operating Altitude Limits

CESSNA SECTION 2
MODEL 2088 (675 SHP) LIMITATIONS
FUEL LIMITATIONS (Continued)
1. For all flight operations in ambient temperatures below 5C, the
fuel used must contain an anti-icing fuel additive in compliance
with MIL-1-27686 (EGME), or MIL-1-85470 (DIEGME). For
operations where the entire flight and ground profile will be
conducted in ambient temperatures above 5C, the use of an
anti-
icing fuel additive in compliance with MIL-1-27686 (EGME), or
MIL-1-85470 (DIEGME) is optional. If fuel with EGME or DIEGME
is not used, the operator is required to use one of the biocidal
additives listed in Section 8 of this manual. Any operation with
fuel that does not contain EGME or DIEGME, will require the
operator to verify appropriate concentration levels
of EGME or
DIEGME in the aircraft's fuel system whenever these
components are reintroduced.
CAUTION
JP-4 AND JP-5 FUELS PER MIL-T-5624 AND JP-8 FUEL
PER MIL-T-83133A CONTAIN THE CORRECT
PREMIXED QUANTITY OF AN APPROVED TYPE OF
ANTI-ICING FUEL ADDITIVE AND NO ADDITIONAL

providing other specified engine limitations are not
exceeded.
3. When using aviation gasoline, the maximum fuel and ambient
temperature for takeoff is
+2goC (85°F) and the maximum
operating altitude is 9000 feet. The boost pump must be ON for
all flight operations.
Refer to Section 8 for additional approved additives and
