Abstract: Methods, systems, and assemblies for operating an aircraft having a turboprop engine are described. The method comprises obtaining a measured torque of the turboprop engine from a mechanical torque piston measurement system and displaying the measured torque in a cockpit of the aircraft. During operation of the turboprop engine, a torque measurement saturation condition of the torque piston measurement system is monitored to detect when the torque piston measurement system is outside of an operating range. A synthesized torque of the turboprop engine is determined based on one or more actual engine operating parameters of the turboprop engine. In response to detecting that the torque piston measurement system is outside of the operating range, the synthesized torque is displayed in the cockpit of the aircraft.

Abstract: Herein provided are methods and systems for detecting blockage of an inlet of gas turbine engine. An oil temperature measurement of the engine and an ambient temperature measurement is obtained. The oil temperature measurement is compared to a threshold based on the ambient temperature measurement. Blockage of the inlet of the engine is detected when the oil temperature measurement exceeds the threshold.

Abstract: A striker assembly including a stern, a striker head, and an insert for the striker head. The insert has an exposed surface of an abrasive or other suitable material for conditioning a striker surface of a bird call device and/or a recess containing a material for cleaning, shaping and/or re-contouring the tip of the stern.

Abstract: A medical lead adaptor assembly for making an electrical connection between a cardiac lead and an external medical device, with the cardiac lead including a lead connector pin for electrically coupling the cardiac lead to the lead adaptor assembly. The lead adaptor assembly includes a connector end assembly that electrically couples the lead adaptor assembly to the external device, a housing portion that has a lead receptacle portion including a lead receptacle that receives the lead connector pin of the cardiac lead to electrically couple the cardiac lead to the lead adaptor assembly, and a retaining flange that extends from the housing portion and has a retaining slot that receives and retains the cardiac lead to substantially prevent corruption of the electrical coupling of the cardiac lead to the lead adaptor assembly.
