SET LIMITS
1. max. knots = 500.0 4. max. feet = 50000
2. min. knots = -200.0 5. min. feet = -2000
3. max. mach = 1.000 6. max. ft/min.= 6000
There are six limit values that can be set. These limits are checked when a Target value is
entered. If the target value exceeds any of the limits, an error is generated. The Actual values
are also checked when the 6300-M3 is in the “Control” mode. If any of these limits is
exceeded by a pre-defined amount, an error will be generated and the 6300-M3 will revert to
“Measure” mode.
An explanation of each limit follows:
1. Max. knots :
This defines the maximum airspeed that can entered as a Target value or
generated as an Actual value. Typically this is set to the maximum airspeed that the
instruments on the aircraft can tolerate. The maximum value for this limit is 1100 and the
minimum is 0. A typical setting for this limit is 500.0
2. Min. knots :
This limits is usually negative and it defines the maximum “Negative
Qc” that the airspeed instruments on the aircraft can tolerate. In most cases it should be set to
about “-200.0” since almost all airspeed indicators can tolerate at least that much negative Qc.
Setting it any closer to “0.0” may cause the limit to be tripped very frequently. The maximum
value for this limit is 0 and the minimum is –900.
