A regional airline pilot flies passengers to and from small and mid-sized airports. They also ferry passengers to major airports, where connecting flights on larger planes await. Typically, a regional pilot carries between 19 and 70 passengers, depending on the size and type of planes the airline uses.fter gaining experience by accumulating flight hours, first officers may become captains, who earn an annual average of $55,000. If a captain is taken on by a major airline, it is usually to the position of first officer or flight engineer. Once promoted back to captain, the average annual salary is about $135,000.
1 The action potential opens gates in the muscle's calcium store (sarcoplasmic reticulum). 2  Calcium ions flow into the cytoplasm, which is where the actin and myosin filaments are. 3  Calcium ions bind to troponin-tropomyosin molecules located in the grooves of the actin filaments.
Describe the events that must occur in the muscle cell before calcium is released from this organelle. 3. Jaw muscle contraction (masseter spasm) is one of the key physical findings seen in Davidâs case of malignant hyperthermia. Explain how calcium functions to cause contraction of a skeletal muscle cell. 4. Dr. Hodges notes that Davidâs exhaled carbon dioxide levels are elevated.
