Flight Model for Western Front Patch 2  - by Greybeard -  23 september 2008.

FEATURES
This FM is suited as is ONLY for WFP2-Release9 and higher, that require mandatory GabiLaser's "ReLoad" program with "Front Guns" option enabled to be executed. 
This FM works only in "authentic" mode (in RB3D Realism Settings).

INSTALLATION
Unzip into your CM11\Patches folder. Install by Campaign Manager.

New in v.3
Fixed monoplanes tendency to stall and spin.

NEW IN VERSION 2
Reduced power outputs of rotary engines by 10% to keep count of windage losses (actual value was applied where available). Corrected top speed of Halberstadt D.II, Nieuport 17, Nieuport 24, Nieuport 27 and Fokker Dr I. Revised Nieuport 10, 12, Voisin III and Farman 40. AI behaviour more suited to aircraft type. Refined wing warping effectiveness for Fokker E.III and Morane Bullet. Revised powers according to actual examples on test bench (wherever available); converted CV and PS to HP. More realistic combat radii for all aircrafts.

History of previous versions:

UPDATE 1/9/2007
Corrected stall, negative stall and zero lift AoA of wingj010.dat according to NACA 124, ref.247 (Goe.298). Raised Dr.I wing incidence to 2.4° and reduced tailplane one to equivalent of 4.7° according to related "Baubeschreibung" dated november 1917. Replaced Dr.I powerplant with 130 HP Le Rhone, coupled with an Axial prop. Revised max RPM. Corrected Nie.11 wings incidence and dihedral.Corrected all aircrafts aileron effectiveness according to formulas of NACA TN 144. Revised all "OuterWingArea" according to related ailerons span and number (2, 4 or 6). Corrected nominal cruising speeds for non flyable aircrafts. Improved Fokker E.III max speed. Introduced new Breaking Load Factors (g-loads) for all aiplanes. Revised early Albatros D series' engine power and RPM according to what reported on Lagorgette's "Avions Allemandes". Revisited all non flyables about their specifications and performances.


FINAL VERSION
Minor refinements. Revised Caudron G.IV. Fixed previously overdone Roland D.VIb. Corrected all "take-off" speeds.

Upgrade 23/12/06
Corrected roll rates, engine torques and attitudes. Fixed Pfalz D.III tendency to stall and spin.

Update 26/11/05
All aircrafts have been thoroughly revised to get them as close as possible to their historical characteristics. Detailed info are reported at bottom of this notes. Revised all tailplanes. Introduced high compression engines. Fixed Vickers Gunbus and DH2.

New in version 7
Raised bombers and two-seaters to same standard (see below) of scouts, correcting many wingspans and wing areas.
Already done in previous v.6.5: improved longitudinal stability of all aircrafts. Introduced Munk's factor. Corrected some airfoils. Fixed Brisfit scout.

NOTE
A directory 160101 has been made, containing FM files previously stored into 150801. FM files into 150801 has been revised to have a second slot (1B) occupied by BE2 as well as Farman F40 into slot 1E.

DISCLAIMER
I tried to reach a good compromise and, in my faith, those scouts seems believable and  balanced in dogfights. I don't want let you believe that this FM is absolutely "historical": there are for sure inaccuracies and errors I wasn't able to avoid. I just hope you enjoy it, tasting a credible "WWI atmosphere" of aerial warfare.

TECHNICAL DETAILS
For each and every flyable scout (and some two-seater) are reported main specifications and performance as you get with this patch; they are engine type and its propeller, max speed (T.A.S.) and altitude:
