I haven’t seen any Jeppesen Tech Star Flight Computer manuals online, so here’s a feature summary.
- uses 4xAAA batteries, thus prone to corrosion
- comes with plastic film to protect keyboard (leave it on)
- math calculations are instant, but menu takes 2 seconds
- arrow keys not used
- no constant memory
- no Mach calculations
Menus are simple … what you see is what you get. That’s all.
right function button – input value from current display
CMP right function button – calculate output
RCL RCL- view all 6 memory locations
STO 1-6 – save current display value to a memory location
RCL 1-6 – restore memory location to current display value
Use the following formula to calculate TAS from Mach number:
TAS = approximate square root to one decimal place(Celsius + 273.15) * 38.94 * Mach number
