Known Problems
As AFS is still under development, there are some known problems in this
version, they will be corrected in the next version, and provide freely as
Patches on our WEB server. If you find a new problem, don't hesitate to contact
us in order that we'll fixed it.
0) WE APOLOGY FOR THE ENGLISH, AS SOON AS THE DOCUMENTATION WILL BE CORRECTED
YOU COULD FREELY DOWNLOAD IT FROM OUR WEB SERVER.
1) In logs section , Aircraft repositioning is no accurate, its depend on
Zoom ratio
2) The french Navaids/Runways are not accurate, Its better to use PAINE FIELD
airport (its parameters are from FAA), you could also enter your own navaids
/ runways.
3) In log section the aircraft path beginning is sometime wrong (a big vertical
line)
4) The beginner mode for Propeller is not implemented
5) The mouse Hand sometimes still on the screen.

physics :
-
Slipstream implemented for single propeller engine
-
Asymmetric trust or power on multi engine
-
Load factor is pitch and bank dependent only at the present time.
-
Atmosphere is standard or weather dependent
-
rho is computed up to 65,616.00 ft
-
static pressure is computed up to 65,616.00 ft
-
Temperature is computed up to 154,199.00 ft but above 65,616.00 ft rho and
static pressure are still computed with equations for 65,616.00 ft, so errors
may occur.
-
Supersonic and hypersonic computation are not yet implemented
Navigation :
-
ILS, VOR, ADF, LOM, RMI, HSI functional
-
World is trigo spherical
-
Approach lighting system implemented
-
Map in Log section is conformal ((orthomophic)(constant heading=a straight
line on the map))
-
Compression error on ASI
-
Altitude density error on ASI
Engines
turbofan :
-
Altitude effect on trust
-
Trust effect and behavior with fan rpm
-
Trust effect and behavior with outside temperature
-
Trust effect and behavior with EPR (engine pressure ratio)
-
Trust may be negative with EPR < 1.0
-
Altitude effect on fuel flow
-
Speed and altitude effects (dynamic and total pressure) on fan windmill and
relight capability (hot start possibility)
-
Automatic computation of fuel flow depending on engine size and efficiency
(specific fuel consumption)
-
Mach limit effect on barber pole
realistic starting sequence :
-
Set power level to ground start
-
Engage starter
-
When sufficient rpm for cooling the plugs set igniter on (high)
-
When sufficient rpm for startup open high pressure valves
-
When egt is alive (first grad) set power level to ground idle
-
Set igniter on (low) to takeoff
-
Set igniter off for standard cruise and velocity
-
If starter sequence not executed this way, a hot start may happen, this may
burn the turbine on a real plane.
Atmos reciprocating :
-
Altitude effect on manifold pressure
-
Altitude effect on engine rpm if fixed propeller, or out of propeller adjust
range for a constant speed propeller
-
Constant speed propeller automatically selected if the propeller control
is selected during panel build
-
Propeller setting effect on engine rpm if constant speed propeller
-
Altitude effect on mixture control
-
Mixture control effect on power
-
Automatic computation of fuel flow depending on engine power
-
Efficiency magnetos functional (left, right, both or OFF)
-
Speed and altitude effect (dynamic and total pressure) on propeller windmill
-
Speed and altitude effect (dynamic and total pressure) on propeller rpm for
a given power set, if fixed propeller
-
VMCA decrease with altitude, it can eventually goes under indicated VS !
Turbo reciprocating :
-
Altitude effect on manifold pressure and turbo boost value
-
Effect of Turbo pressure control valve type on turbo boost value (pop off
valve)
-
Altitude effect on engine rpm if fixed propeller, or out of propeller adjust
range for constant speed propeller
-
Constant speed propeller automatically selected if the propeller control
is selected during panel build
-
Propeller setting effect on engine rpm if constant speed propeller
-
Altitude effect on mixture control above turbo critical altitude ( WARNING
possibility of flame out if abrupt power reduction at high altitude, due
to turbo stalling ,a restart may be impossible at this altitude).
-
Mixture control effect on power
-
Automatic computation of fuel flow depending on engine power efficiency
-
Magnetos functional
-
Speed and altitude effects (dynamic and total pressure) on propeller
-
VMCA decrease with altitude above turbo critical altitude,it can eventually
goes under indicated VS ! If an overboost occurs with fixed or failed turbo
regulator valve , VMCA will increase above published values.
