New Aviation Gasoline Grade 100VLL
Grade 100VLL
aviation gasoline (avgas) is developed to provide a lower lead alternative to
100LL in response to impending environmental regulations. Grade 100VLL is
identical to 100LL in all aspects, except that the maximum lead content is
reduced by about 19%.
Grade 100VLL has the same minimum octane rating
and will provide the same level of anti-knock performance as 100LL and 100
avgas grades.
The FAA
collaborated with industry on the ASTM International task force that evaluated
data supporting the incorporation of grade 100VLL into specification D910. The
FAA determined that grade 100 VLL meets all of the performance requirements of
grades 80, 91, 100, and 100LL and will perform identically in existing aircraft
and engines
FAA
1. Grade 100VLL
avgas is acceptable for use on those aircraft and engines that are approved to
operate with grades 80, 91, 100, or 100LL avgas.
2. ASTM D910
specifies blue coloration for both grade 100VLL avgas and grade 100LL avgas,
and, therefore, these fuels are visually indistinguishable from each other.
3. Operating
limitations in Aircraft Flight Manuals, Pilot Operating Instructions, or TCDSs
that specify grades 80, 91, 100, or 100LL avgas fuel are acceptable for use
with grade 100VLL avgas.
4. Current aircraft
placards that specify grades 80, 91, 100, or 100LL avgas are acceptable for use
with grade 100VLL avgas.
5. Operating,
maintenance, or other service documents, for aircraft and engines that are
approved to operate
with grades 80, 91, 100, or 100LL avgas, are acceptable for use when operating
with grade 100VLL avgas.
