but they do
Hello
The Saab 2000 has Flex which does the same as on a jet. The value (in power units) to be set is taken from assumed temp tables.
The Saab 340 does not have dedicated Flex or assumed temp setting but you can take off setting a lower torque (the unit for power on the 340). To find how low, you consult assumed temp tables, providing your operator has them.
