This article provides some guidelines on cleaning and disinfecting simulators and simulator equipment.
On older model 141s and 142s, the GISt Backup utility executable did not actually hold the number of backups to be saved to 25. The result is that backups continue to be saved until the GISt computer hard drive becomes filled with backup, resulting in a sluggish or (worst-case) inoperative GISt computer.
On the configuration menu, a customer had an “exit to DOS” button partially hidden by the “more configuration info” button. On the aircraft position page, the aircraft symbol was not positioned on the correct locations within the pattern.
Adjust this constant when tuning a model that requires more or less aileron roll effect when an engine is failed.
Customers with more than one Frasca FTD occasionally decide to swap components between simulators for troubleshooting purposes. There is some parts interchangeability between simulators. Generally, if the part numbers are similar…
The Frasca P/N V-56-35 or M-58-012 linear potentiometers are obsolete. To replace these potentiometers with current parts, the toe brake and cowl flap assemblies must be replaced. For throttle potentiometers (both single- and multi-engine quadrants), the quadrant must be returned to the factory.
he Synchro Board contains one trim potentiometer for each of its nine output channels. Each channel is calibrated by outputting 0000H to its DA converter and then adjusting its corresponding trim potentiometer to null any AC voltage on its output.
I was recently asked to look at a problem of jittering HSI compass cards on 14X simulators. The HSI card was reasonably stable when a very old Servo Board was used, but it jittered with new Servo boards (131158-1)
The Standard CAN Radio panel (Frasca P/N 111728-X, also known as the SAP 100) CPU chip may pop out of it’s socket or become loose over time.
The Servo Board (800-00018) interfaces the Converter board to various indicators and controls that are used in the simulator. The Servo Board is an Analog Board that should never be plugged into a digital slot on the motherboard.
