Ok, enough of this washing machine malarky and time for an update.
I think it's safe to say that bringing Tango into the team was a wise decision, the man is a machine!!!
In just a couple of weeks he has achieved what would have taken me several months to code.
All code has been written from scratch based on the Hawk systems and behaves exactly like a BAE Hawk T.1A.
Here is a simplified list of what is currently functional within the cockpit:
ELECTRICAL SYSTEM
- Batt 1 and Batt 2
- Battery discharge logic
- Battery charge logic (Hawk T1.A spec)
- Commoned battery bus
- Battery contactors
- Essential Bus
- Generator bus
- Ground power connection logic (Hawk T1.A spec)
- Ground power shortcut key
- Ground power contactor
- All AC inverters, transformers and contactors are modelled
- Standby instruments and standby radio power switches
- All systems will be tied to the correct busses, requiring certain minimum voltages to operate
AHRS - ATTITUDE DIRECTION INDICATOR (PRIMARY ADI)
- Attitude indicator
- Gyro spool-up and down, and accurate useful run-time after power failure
- Acceleration effects due to maneuvering
- Acceleration effects due to increase/decrease in speed
- Natural erect rate
- Fast align sensitive to gyro RPM
- Auto fast-align based on power state
- Fail flag
AHRS - HORIZONTAL SITUATION INDICATOR (HSI)
- Gyro-spool up and down, and accurate run-time after power failure
- DG mode Earth rate error based on aircraft latitude
- DG mode transport rate error sensitive to aircraft latitude, heading and ground speed
- DG mode transport rate correction (fixed at 350 kts GS and sensitive to aircraft heading)
- DG mode Latitude selector knob fully operational (used to calibrate earth rate and transport rate corrections - AHRS does not know aircraft position)
- DG error accumulation due to maneuvering
- DG mode tumble
- DG heading manual set function
- SYNC mode includes magnometer simulation (located in the top of the vertical fin)
- Magnometer errors due to maneuvering (positional)
- SYNC mode auto correct rate at 1.5 degrees/min during level unaccelerated flight using inputs from magnometer
- Manual and auto FAST SYNC mode
- SYNC IND fully functional in SYNC mode (parks in vertical position in OFF or DG modes)
- Fail flag
STANDBY ATTITUDE INDICATOR
- Gyro spool-up and down, and accurate useful run-time after power failure
- Gyro errors specific to this instrument
- Acceleration errors
- Maneuvering errors
- Instrument-specific transient errors during maneuvering
- Multiple failure modes (topple compensation mechanism and topple due to maneuver limits being exceeded)
- Manual cage mode/erect
- Natural erect rate
- Fail flag
STANDBY DGI
- Gyro spool-up and down, and accurate useful run-time after power failure
- DG mode
- Maneuvering limits
- Accumultive error due to maneuvering
- Earth rate error
- Transport rate error sensitive to aircraft heading
- Manual heading set
- Manual cage function
- Topples when maneuvering limits exceeded
- Fail flag
TURN AND SLIP CO-ORDINATOR
- Gyro spool-up and down, and accurate useful run-time after power failure
- Topples (permanent in-flight as no reset function)
- Inaccurate at low RPM/topples on ground if spin-up time not observed before taxi
- Fail flag (flag disappears when at operating RPM)
DUAL AIRSPEED INDICATOR
- Compressibility effects
- Outside Air Temperature affects Mach (simulation weather system limited)
- Affected by alpha and beta
PRIMARY ALTIMETER:
- Requires DC supply
- Kholsman calibration window (hPa)
- Displays density altitude (sensitive to OAT as well as pressure)
- Fail flag
BACKUP ALTIMETER
- Pure pressure instrument
- Kholsman calibration window (hPa)
- Displays density altitude (sensitive to OAT as well as pressure)
VERTICAL SPEED INDICATOR
- Based upon atmospheric model
- Instrument lag
MAGNETIC COMPASS
- E2C compass including all behaviors during turns ("swing" sensitive to heading and direction of turn, sensitive to acceleration, pendulum effects)
- Integrated lighting
AIR DATA SYSTEM
- Complete air data simulation
CAUTION AND WARNING SYSTEM
- CAWS (Caution and Warning System) core fault system is implemented and fully functional.
- Attention-getter lights fully implemented with complete logic.
COCKPIT LIGHTING SYSTEM
- Panel night lighting in development
- Tied to correct electrical systems
- Fully independent brightness control system
- Emergency lighting system tied to DC ESS bus
- Emergency lighting dimmer due to reduced number of bulbs used for function
I'm hoping to record some video this week to post up, so keep an eye out for that.
Thanks,
Chris.
