The Boeing Maintenance Manual has this sentence about V/S indications...
"The scale defined for the 2000 to 6000 feet per minute range
is extended to the upper or lower display range limit when the vertical speed exceeds the analog display range limit and the pointer parks in view at the upper or lower limit."
I'm having trouble understanding it.
According to the manual, the adjacent digital fpm display (which appears if V/S's are above 400fpm) has a limit of 9999fpm.
The 2000~6000fpm range is linear, according to the manual. If the scale and needle were to extend to 9999fpm, they would (graphically) interfere with the digital display.
Has anyone seen this in the sim... or lived to see this display in real life?
Thanks.
Rgds.
