Acceleration Limitations
Avoid accelerations greater than those required for level banked turns, max 2g positive. Accelerations less than 0.5g positive (pushover) may result in loss of engine oil pressure and shall be avoided. Operation within these limitations promotes passenger comfort, assures cargo integrity, and enhances aircraft service life. Aircraft design maneuver loads at design gross weight are:
1. 3.17g positive, 1.27 negative clean config
2. 2g positive, 0g negative with flaps down.
82
Fuel Management
1. Takeoff is prohibited if either fuel quantity gauge indicates in the yellow arc or less than 265 pounds of fuel
2. Operation w/fuel pressure light illuminated is limited to 10 hrs between engine driven fuel pump overhaul or replacement periods
3. Operation on aviation gasoline is limited to 150 hours during any one engine overhaul period
4. Auxiliary tanks shall not be filled unless the main tanks are full
5. Maximum fuel imbalance between fuel systems is 1000#
6. Crossfeed - refer to EP section
83
ST190 Saddle Tanks
1. Total fuel system capacity for aircraft incorporating the ST190 saddle tanks is increased by 190 US gallons (95 gallons each) to 734 gallons
2. A maximum allowed fuel imbalance between left and right ST190 saddle tanks is 300 pounds (45 gallons)
3. ST190 saddle tanks shall not be filled unless the main and auxiliary tanks are full
