CRJ 200 FMC PERF limiting

[jagipson]

When using the PERF page on the FMC to limit the throttle using temperature, which is correct? Enter the ISO temperature, or OAT (Outside Air Temp displayed on the PFD/MFD)?

If entering the OAT, do I periodically update thr temp as I climb, or is the correct temp just supposed to remain the OAT at the departure airport ( in other words, are the calculated throttle limits taking typical altitudes into account? )
