- All sides aircraft performed worse when flown as captured aircraft. That includes Soviet types... look at the La-5FN test by the Luftwaffe for example and compare it to the official Tzagi tests. The Soviet Ace's opinion is probably true... he wouldn't get the same performance as the factory did when he flew a captured aircraft.
- It was very common for different aircraft of the same type and model to have as much as 5% difference in the horsepower produced by the engine... this was a fact of mass production in an era where quality control was not what it is now. Tests of two aircraft of exactly the same type and model show two different results.
- Depending on how many hours an aircraft has on it, or how severely it has been used, performance of an aircraft in the field can easily be as much as 10% below factory specs.
As I have said before, I model aircraft based on all the evidence available.... I rate the reference material based in the following hierarchy:
Rating 1: Factory or Airforce tests by the originating country (country which designed and manufactured the aircraft)
Rating 2: Airforce tests by countries Allied to the originating country
Rating 3: Tests by Hostile country's Airforces of captured aircraft
It is a fact that sometimes factories were over optimistic and set 'expected' boost or rpm levels, were able to achieve these levels at the factory, only to find in the field under continuous use their aircraft couldn't sustain those levels and be mechanically reliable.... sometimes re-designs are required before the higher boost or rpm was 'cleared'. This was the case for Soviet, German, British and Japanese types. The US was better this way because they had the money and resources to create large design teams and additionally to test more extensively. In a few aircraft types the level of boost/rpm hoped for was never achieved. These instances of aircraft being rated operational, then being 'de-rated' to a lower level of performance were not unusual and obviously cause confusion in the records. In all cases, I base my decisions on what evidence there is available. Sometimes a judgement call is required.
Any flight sim which claims their game 'perfectly' replicates the real aircraft is blowing smoke rings up the butts of their customers. There are no perfect Flight Models and there never will be... a flight sim is a flight sim, not an aircraft. A flight SIMULATION is exactly that, a simulation of the real thing, within the confines of the very limited resources of a personal computer, an electronic joystick/pedals and a computer screen/VR googles.
Within the limitations of the game's physics engine, and the data available, TF will strive to simulate these extremely complex aircraft with their very complex flight behaviour. (far more complicated than a modern Jet when you consider the effects of propellors and reciprocating engines) The most important thing in my opinion, is that particular aircraft types are balanced against the other competing types in terms of their relative performance advantages... trying to duplicate exactly the climb/speed/etc. of a particular aircraft at all altitudes is in most cases almost impossible and a fools game. If the aircraft can come within 5%, then there is reason to be satisfied.
In the end, if a player can use the tactics and maneuvers which the historical pilots used, and see similar results when matched up against the competing aircraft types, then there is reason to be positive about the simulation.
