| - | ===BALANCING=== | + | ====BALANCING==== |
| This is always the bogey man with flight sims. No attempt at balancing per se has been made. The intention was to achieve documented performance with each type. If this could not be achieved (due lack of Sim coding capability and or knowledge of that code) then the relative performance between comparative types was the goal. We wont ever get it perfect. Ceilings are a case in point. | This is always the bogey man with flight sims. No attempt at balancing per se has been made. The intention was to achieve documented performance with each type.

| Huge amounts of work have been done here to eliminate or minimise the CLOD altitude bug. Varied methods have been used to achieve this (and the methodology will be kept to those that need to know) . In the end we set a baseline minimum altitude capability of 30,000ft/9133m for most single engine fighter types and this has been achieved. Some types (for you to find out) can fly a bit higher than this. | Huge amounts of work have been done here to eliminate or minimise the CLOD altitude bug.

| - | ===STRUCTURAL G=== | + | ====STRUCTURAL G==== |
| We have implemented Structural G based on Ultimate load to all flyables. This does not take into account weight reduction due fuel and or a stores expenditure. At this stage blanket Ultimate load values of +10/-4 have been applied to all single engine fighter types. Heavy Fighters BF110 +8/-3. Exceed the ultimate load and you will lose a wing. Few if any types have sufficient elevator authority to exceed the negative G limit. No deformation due to minor over G occurs. At this stage it is beyond the game engine capability. Heavy/Medium level bombers (HEIII,BR20, +4/-2), Medium DB (JU88)Blenheim IV , +6/-3, JU87B +10/-4 Values not added to AI types until we are sure of their reaction. You may decide that a specific Key binding is required for the bombers to set up their elevator pitch sensitivity to minimise the risk of Overstress. These were big aeroplanes with significantly higher stick forces than the fighter types. | We have implemented Structural G based on Ultimate load to all flyables.

| - | ===TRIM CHANGE WITH FLAP=== | + | ====TRIM CHANGE WITH FLAP==== |
| This has been corrected so that a nose down trim change will occur with flap deployment. It is most noticeable in the Spitfire with its simple two position flap system. It is barely noticeable in BF110. IRL the BF110 had a fairly strong natural tendency to pitch up with flap selection, this was countered by a mechanical interconnection with stab that moved automatically to compensate the trim change. This mechanism is not modelled in CLOD. We have represented this by a very slight up trim change with flap selection. | This has been corrected so that a nose down trim change will occur with flap deployment.

| - | ===TRIM CHANGE WITH LANDING GEAR=== | + | ====TRIM CHANGE WITH LANDING GEAR==== |
| Most aircraft types with longitudinally operating landing gear (Blenheim,HEIII,BF110,BR20,JU88 etc) experienced some trim changes with Landing gear extension. There are two reasons for this C of G change and a raising and or lowering of the drag line. These 2 factors generally operate against each other, however the C of G change tends to dominate. In those types with longitudinally operating landing we have incorporated a Nose UP trim change with gear extension, and vice versa. | Most aircraft types with longitudinally operating landing gear (Blenheim,HEIII,BF110,BR20,JU88 etc) experienced some trim changes with Landing gear extension.

| - | ===ALTIMETERS=== | + | ====ALTIMETERS==== |
| All Flyable aircraft altimeters are now set to an initial or default Sub scale (QNH) setting of 1013mb or 760mm. Given the new standard map sea level pressure you shouldn't have to adjust the altimeter setting. Full ability to vary the setting is unchanged. So if you like to fly on QFE you can do so. Altimetry routines have been extensively re written. This has affected all aircraft ceilings and Vmax at altitudes from those achieved in the stock game. Cockpit Altimeter and No cockpit altimeter should now be in close agreement. RAF Altimeter minimum subscale setting is now 940mb. In addition a conversion factor related bug between Metres and feet in Wonder Woman view has been corrected. | All Flyable aircraft altimeters are now set to an initial or default Sub scale (QNH) setting of 1013mb or 760mm.

| 100 octane versions of the Spit I DH 2 pitch and Hurricane DH 2 pitch have been introduced. The 87 Octane 2 pitch aircraft versions are still available. Having 100 Oct versions available to all RAF types accurately reflects the situation in BOB. In addition C3 100 Octane BF109E4N is in this release. | 100 octane versions of the Spit I DH 2 pitch and Hurricane DH 2 pitch have been introduced.

| - | ===OVERHEAT ROUTINES=== | + | ====OVERHEAT ROUTINES==== |
| Basically the Cooling capability is defined by being able to run for 5 minutes at the 5 min rating at Full throttle Height (FTH) with Rads Fully open at Climb IAS. This represents the worst possible scenario of max engine heat output with minimum cooling due to lower mass flow (Density and climb IAS). Increased altitude does provide some beneficial cooling but the effects of lower mass flow dominates. In the end the rationale is if the system can achieve the 5Min Rating in this scenario it will handle most other (less limiting) scenarios such as high speed Vmax runs (Though at FTH this is only just at any other altitude no issues) or sustained operation at lower levels with lower RAD settings. You should be able to push things a little harder in the lower altitudes than previously. | Basically the Cooling capability is defined by being able to run for 5 minutes at the 5 min rating at Full throttle Height (FTH) with Rads Fully open at Climb IAS.

| Prop pitch on the HEIIIH/P and JU88 were previously Hybrid Constant Speed systems that were very loose. Historical data indicates that the HEIIIH and P had straight out Variable Pitch (VP) props. These have now become the standard prop for these two aircraft. Directionally the mechanisation is the same as the BF109 and BF110. The JU88 is a special case. Documents indicate that the JU88A1 had a special limiter mode that limited RPM to 2350 and was designed for Take Off and Dive deliveries but it was not a conventional Constant Speed system. In other Flight regimes a Manual mode was selected and then the prop system was a standard VP system. At this stage it is not possible to model the Limiter Mode accurately. In RC4/RC5/RC6 after extensive rework the JU88 is now also a straight out VP system. There were some issues at altitude with the JU88 and getting the pitch coarse enough to hold 2100RPM at 5000m. This had been addressed in RC6 and should no longer be an issue. Directionally the new JU88 VP, HEIIIH/P VP system is the same as the BF109. The only odd man out in the German side of the house is the JU87. Its CSP system is directionally the same as the RAF types. Because of these variations it may be better to have dedicated Key binding Files for the JU87. You can copy Key bindings and save to a specific name and chop and change these even in mid-flight. A simple way is to have a Master key binding file. Then use this as the basis to make alterations required by individual types. Save the new file with the types name. | Prop pitch on the HEIIIH/P and JU88 were previously Hybrid Constant Speed systems that were very loose.
