Standard Empty Mass 1764 lbs,

Optional Equipment 35 lbs

Pilot + Front seat passenger 300 lbs

Cargo Mass 350 lbs

Ramp Fuel = Block Fuel 60 Gal.

Trip Fuel 35 Gal.

Fuel density 6 lbs/Gal.

Start up and Taxy Fuel 10 lbs

T/O mass = 1764 + 35 + 300 +350 + (60 x 6) – 10 = 2799 lb

Fuel at take-off = Ramp - Taxy

Question is not good – optional equipment is a bit of a doubt – seems to me that its ‘optional’ – you may have it – we would need to appeal!
