When should you use PARA vs PARA SERIES
PARA for EXTERNAL POWER to avoid high current
PARA-SERIES for internal Battery
What is the effect of engine inlet anti-ice on takeoff torque limits?
Where altitude/temp does not permit 100% torque decrease torque setting by 2%
What is the effect of cabin heater on takeoff torque limit?
Where altitude/temp does not permit 100% torque decrease torque setting by 3%
What is the effect of OAT and altitude on torque settings?
Higher OAT and/or higher altitude means you will hit the temp limit first at which point torque setting reduces below 100%, the hotter or the higher - the lower torque setting
