ATCoach  Tactical Edition PAR Simulator (APARS) DATA MANAGEMENT: ATCOACH FILES PART FOUR

1. ATCoach Tactical Edition PAR Simulator • (APARS) • DATA MANAGEMENT: • ATCOACH FILES • PART FOUR • Aircraft Model File • CLS2004.A.0-004.4

2. Aircraft Model File • Aircraft Model File - (UM Section 4.2.3 & App A) • The Aircraft Model file contains the aircraft definitions that are used for simulation exercises. • Each aircraft type has performance characteristics that must be present for ATCoach to function. • The user can edit the file by adding aircraft or modifying existing aircraft performance characteristics. • The aircraft model file is limited to 200 aircraft. • In a simulation exercise, if an aircraft type is entered that is not in the file; it is ignored and indicated in the scenario error file.

4. Aircraft Model File • MOD Aircraft type (Model). • This field contains from two to four characters that identify the aircraft manufacturer and model name of the aircraft type. • CLS Class. • For the purposes of Wake Turbulence separation minima, ATC classifies aircraft as Heavy, Large, and Small as defined in FAAO 7110.65, These classes are defined as H, L and S respectively in the aircraft.model file. • ENG Engine type. • Engine types are defined as Turbojet (J), Propeller (P), and H (Helicopter). This information is useful when procedures are defined differently to accommodate each type. (DP for example).

5. Aircraft Model File • CAT Size Category. • This field is used in Visual Approach logic. Numbered 1 through 4 ranging from least to greatest size, i.e., 1 is single engine propeller driven, 2 is light twin engine, 3 is larger corporate type aircraft and 4 is air carrier type with no differentiation for large or heavy. The category selected determines the point the aircraft will turn onto final approach with no traffic to follow. These numerical descriptions are subject to the developer’s preference. • CLIM RATE Climb rate. • This field defines nominal climb rate in feet per minute from mean sea level (msl) through terminal altitudes. The rates may be modified during runtime with accelerated rates specified (equivalent to “expedite” and “immediate” clearance). Accelerated rates are the nominal rate plus a percentage dependent upon Engine type and limited by pressure altitude.

6. Aircraft Model File • DESC RATE Descent rate. • This field defines the nominal descent rate in feet per minute. The rates may be modified at runtime with accelerated rates specified by percentages as noted in the Climb rate but not restricted by altitude. • TURN RATE Turn rate. • This field determines the turn rate of the aircraft in degrees per second at lower altitudes. By convention, 3 degrees is standard rate. At flight level 290 or higher aircraft will decrease turn rate to one half the standard rate. • ACC RATE Acceleration rate. • This field is the acceleration rate of the aircraft in nautical miles per second. For example, at four-second radar scans, an acceleration rate of 1.5 will appear as a 6-knot increase in speed at each radar update.

7. Aircraft Model File • DECL RATE Deceleration rate. • This field is the deceleration rate of the aircraft in nautical miles per second. • APP SPD Approach speed. • This field defines the approach and final landing indicated airspeed (IAS) in knots. At the approach fix the aircraft will reduce speed at its defined deceleration rate to the approach speed, which is maintained until landing. • MAN SPD Maneuver Speed. • The maneuver speed is user defined and used when an aircraft is told to perform landing check.

8. Aircraft Model File • CRUS SPD Cruise Speed. • Cruise speed is user defined and used when the aircraft is outside of the radar traffic pattern. • STL SPD Stall speed. • This is the IAS at or below which the aircraft will stall. The system will not respond to speed inputs at or below this parameter except with expert system error messages. • MAX ALT Maximum altitude. • This field defines the service ceiling of the aircraft in feet. The Maximum climb rate for the aircraft will degrade linearly from mean sea level until this altitude is reached.

9. Aircraft Model File • MAX VEL Maximum velocity. • This field defines the maximum true airspeed (TAS) that the aircraft can achieve. As the aircraft climbs to altitude the TAS exceeds the IAS by 2 per cent, per thousand feet of altitude. At maximum velocity the TAS can no longer increase. If climb continues, IAS will decrease as altitude increases. • MAX CLIM Maximum climb rate. • This field defines the maximum climb rate in feet per minute. The aircraft may climb at this rate at mean sea level, but the rate decreases linearly as the pressure altitude decreases with climb. Pilot instructions to expedite beyond this rate will be ignored.

10. Aircraft Model File • FUEL CAP (Min) Fuel Capacity in Minutes. • Fuel capacity is entered in minutes and used primarily for aircraft that are in distress or an emergency situation. ATCoach defaults to 120 minutes. • PRSN CAP Personnel Capacity. • Personnel capacity is the number of people/passengers on an aircraft. ATCoach defaults to 10. • BNK ANG Bank Angle. • The bank angle determines the turn rate of aircraft. The angle is based on the aircraft’s true airspeed and the bank angle defined in the aircraft model file. ATCoach defaults to a bank angle of 40 degrees.
