This is the download page for the ACM-5.0-ico version of the ACM Air Combat Maneuvering program. The ACM-5.0 flight simulator was originally written by Riley Rainey (www.websimulations.com). The ACM-5.0-ico version has some additions and some improvements listed in the Main Differences section of this page, whose main aim is to enhance the program for instrumental flight.
Landing with the Cessna 172-RG at the Addison airport, Texas, following the ILS descent path. In this case the autopilot is enabled; it will perform also the flare maneuver for a gentle touchdown.
Dog fight F-16 vs. MiG-29. The HUD displays the target locked on the radar and the currently selected weapon.
Suggestive scenery of the Dallas airport by night. The pilot can practice with the instrumental flight using VOR/DME stations and NDB stations.
Bombing practice with the CCIP calculator. Once the Mark 82 bomb is selected, the HUD displays the CCIP symbols.
The program is distributed under the GNU GENERAL PUBLIC LICENSE version 2.
Here is a summary of the main features:
The classic instruments panel (from the ACM manual; click to enlarge).
For those that already know ACM-5.0, here is a list of the main difference between the original program and ACM-5.0-ico:
A graphical interface to launch the program that allows to choose
between its many options is now provided (
A precise scale factor gets calculated.
Weather: wind, daylight or night flight.
The quantity of fuel can now be specified along the payload
Every aircraft has a maximum vertical load factor; beyond this
structural limit the aircraft gets destroyed.
Proper magnetic heading indication.
You can choose between classic instruments panel and HUD.
Enhanced HUD with turn-and-slip indicator, bank indicator,
timer and radar altimeter.
Enhanced HSI with two independent receivers NAV1/NAV2 and five RNAV
NDB stations receiver and ADF indicator.
Auto-Pilot System: hold climb rate, hold altitude, follow
VOR radial, follow ILS descend path, ailerons/rudder auto-coordination,
Runway numbers now marks runway ends.
Both tricycle and bicycle landing gear supported.
Landing gear dynamics fully implemented on 3 wheel, including aerodynamic
forces moving on the ground.
More aircraft models: AMX, MD-81, Boeing 747, P-51A.
The range of the radio stations now is limited both by emitted power
and by altitude and Earth curvature.
You can leave the ACM window in background and switch to other
Italy scene, with the main airports and NAVAIDs.
Navigation charts in PDF format covering the Dallas scene and the
Italy scene, including runways, NAV and ILS stations.
Resolve properly second order differential equation. Now the flaps state is displayed. Crash for "Color Segment pool overflow" -- fixed. Fixed crash when at rest on the runway.

acm-5.0-ico-20100109 Umberto Salsi <email@example.com> + HUD: pitch scale ladder now rendered in perspective projection, so that it matches exactly the pitch as indicated by the FPM (fix). + Stall warning: panel light + HUD display + audible alarm. + Player whose aircraft is damaged fall down and crashes. + More accurate CCIP HUD symbology (use circle rather than cross). + Mark 82 bomb blast may damage aircrafts. + CCIP: corrected position of the CCIP accounting for the pilot's head position. + Added keypad button 0 to look down. acm-5.0-ico-20090215 Umberto Salsi <firstname.lastname@example.org> + Added Mark 82 drop bombs with CCIP calculator. + Added down view (keypad 0). + Inventory: Su-30 now armed with 4 MK82, 2 AIM9M and M61A1 for bombing practice with CCIP. acm-5.0-ico-20090208 Umberto Salsi <email@example.com> + FIX: the runway numbers are now rendered in the proper order. + FIX: properly evaluates max lateral mouse range. + FIX: corrected elevator non-linear response curve. + Introduced wind gust model. + Anemometer: now displays speed limits arcs. + Attitude indicator: increased gyro rigidity. + Removed keyboard command 'u'. + Auto-Pilot System: + Now implemented using the proportional-integrative algo. + AC: smooth release. + AW: smooth release. + AL: performs flare maneuver at lower altitude. + Weapons: + Enabled radar guided "AMRAAM" missile AIM-120 (previously was disabled). + Drone algorithm now uses AIM-120 first, then AIM-9M. + Inventory file: + Removed unused parameters CLNegStall, CLPosStall, SeTrimTakeoff, CmFactor. + Added parameters MTOW, Vs0, Vs1, Vfe, Vno, Vne. + Weapons have new canonical names M61A1, AIM-9M, AIM-120, MK82. + C-172 has lower pitch. + F-16 and MiG-29 now mount 2 AIM-120. + MD-80 now has the thrust reverser. + Updated manual.
This is only a partial list that reports changes in the last 3 published versions of the program. The complete list is available in the file CHANGES of the distributed package.
