- Chapter 11: Aircraft Performance › Atmospheric Pressure
approximately 14.7 pounds per square inch (psi). The density of air has significant effects on the aircraft’s performance. As air becomes less dense, it reduces: • Power, because the engine takes in less air • Thrust, because the propeller is less ... airfoils The pressure of the atmosphere may vary with time but more importantly, it varies with altitude and temperature. Due to the changing atmospheric pressure, a standard reference was developed. The standard atmosphere at sea level has a surface temperature…

Persons authorized to approve aircraft, airframes, aircraft engines, propellers, appliances, or component parts for return to service after maintenance, preventive maintenance, rebuilding, or alteration. (a) Except as provided in this section and § 43.17, no person, other than the Administrator ... approve an aircraft, airframe, aircraft engine, propeller, appliance, or component part for return to service after it has undergone maintenance, preventive maintenance, rebuilding, or alteration. (b) The holder of a mechanic certificate or an inspection authorization may approve an aircraft…
- Chapter 1: Aircraft Engines › General Requirements › Powerplant Selection
discussed from an analytical point of view. For that reason, a general discussion of powerplant selection follows. For aircraft whose cruising speed does not exceed 250 mph, the reciprocating engine is the usual choice of powerplant. When economy is required ... speed range, the conventional reciprocating engine is chosen because of its excellent efficiency and relatively low cost. When high altitude performance is required, the turbo-supercharged reciprocating engine may be chosen because it is capable of maintaining rated power…
