Fuel Drains; Fuel Quantity Indication - Beechcraft Baron G58 Pilot Operating Handbook

Section 7
Systems Description

FUEL DRAINS

The optional 172 gallon fuel system has six underwing drain
locations. There are two additional drain locations with the wet
wing tip tank system.
These fuel drains are snap-type valves which are actuated by
pushing up and twisting on the valve and then releasing when
the desired amount of fuel has been drained. The drain may be
locked open.
The fuel drains should be sampled after refueling and prior to
each flight in accordance with the Preflight Inspection in Sec-
tion 4, NORMAL PROCEDURES. When possible, the inspec-
tion of the fuel should be made after sufficient time has been
allotted for any contaminants to settle into the sumps. If
inspections are made immediately after the airplane has been
moved or refueled, contaminants may be flushed from the
sump, or newly added contaminants may not have had time to
settle into the sumps. Sampling should be conducted with the
airplane parked on level ground. Check fuel for the proper
grade, type and absence of water, dirt, rust or other contami-
nants.
Do not fly the airplane with contaminated or
unapproved fuel.

FUEL QUANTITY INDICATION

Fuel quantity is measured by float-operated fuel level sensors
located in each wing tank system. These sensors transmit
electrical signals to the engine and airframe interface units
(GEAs) to generate a left and right usable fuel quantity display
in the engine and systems display portion of the MFD.
