If this happens advance Boost slightly as required to ensure CHT is kept above 100C __**LANDING**__ * On Final set Props Full Fine (Plungers IN or to rear) * Consider cowl Flaps 1/4 Open (in case of Go Around) * Approach IAS 85MPH min //**WARNING**// High Rates of Descent at <85MPH IAS can result in running out of elevator authority in the flare. __**GROUND OPERATION**__ * Cowl Flaps Full open | __**LIMITATIONS**__ ^ Temps ^ ^ Min CHT | 100C | ^ Max CHT | 235C | ^ Min Oil Temp | 40C | ^ Max Oil Temp | 85C | * +9Lbs 5 min or temp Limits (OIL/CHT) * Max IAS 285MPH * Flaps 145MPH * Trim Changes * Landing gear Down Nose Up * Flaps down Nose Down **__FUEL SYSTEM__** The Blenheim has 4 fuel tanks. 2 Tanks in each wing referred to as Inner and Outer tanks. Fuel quantity gauges are located above the pilots left shoulder. Two gauges are present to indicate the fuel remaining in both Port and Starboard tanks. Each wing has two tanks Inner and Outer. To read a specific tank Fuel Quantity first select the desired tank using the the rotary switches. **__BOMB AIMERS STATION__** The Bomb aimers station has a number of player controls. Two Yellow Manual Bomb release buttons are located on the Chart table. A total of 4 switches are located on the forward instrument panel. These Mode switches allow the bomb aimer to select Bomb delivery modes. The Bombsight is a simple vector sight. the Bomb aimer sets the current TAS and Release height (Altitude - Target elevation). Setting these values will vary the position of the Sighting index along the Horizontal shaft. the weapon release point is indicated when the target is visible in the small cut outs adjacent to the pointers. Drift Adjustment can also be made. this will slew the entire horizontal arm Left or Right. When the correct Drift is established the target should track directly parallel to the Horizontal shaft. **__BOMB BAY DOORS__** These are Automatic. the Doors are held close by Bungee operation. The weight of the falling bomb will open the doors which will then snap shut after bomb release. __**Air Intake Heat Control**__ Required ON for all operations in cloud or if rough running occurs for no obvious reason.
