FIGURE 1
PILOT OPERATING PROCEDURES - PREFLIGHT FUEL SYSTEM QUANTITY CHECK
The following procedures are to be used on certain Cessna 210, P210, and T210 Series airplanes
whenever more than 75 gallons of fuel are needed for range and reserve.
l. Verify that the airplane is level laterally and is approximately 4.5 degrees nose up
(normal nose strut on a level surface).
NOTE: The airplane turn and bank instrument may be used to check lateral leveling.
2. Visually inspect each fuel tank for fuel level with the upper wing surface when full
fuel capacity is intended to be in each tank.
3. Check each fuel cap and seal for security and wing surface for a lack of fuel stains aft
of each fuel cap.
NOTE: It is highly recommended that the wing tips and flap trailing edges are checked during
flight for evidence of fuel siphoning.
