Rules of Energy Control

The central principle encapsulating the role of the throttle and elevator for managing the airplane’s energy can be summed up as follows: coordinated throttle and elevator inputs control the airplane’s energy state. Modifying a popular adage, the principle can be restated as “pitch plus power controls energy state.” This central principle serves to guide a … Read more

Role of the Controls to Manage Energy State

An energy-centered approach clarifies the roles of the engine and flight controls beyond the simple “pitch for airspeed and power for altitude” by modeling how throttle and elevator inputs affect the airplane’s total mechanical energy. From an energy perspective, the problem of controlling vertical flight path and airspeed becomes one of handling the airplane’s energy … Read more

Single-Pilot Resource Management and Risk Management

Single-Pilot Resource Management (SRM) According to data presented at the 2005 International Helicopter Safety Symposium, the helicopter accident rate is 30 percent higher than the general aviation (GA) accident rate. Reducing this rate is an industry wide goal and the CFI plays an important role in reaching it by stressing single-pilot resource management (SRM) and risk … Read more

Helicopter Flight Safety Practices

A major component of the FAA’s mission is to improve the nation’s aviation safety record by conveying safety principles and practices through training, outreach, and education. The goal to reduce the number of accidents in the ever increasingly populated airways means safe flight practices are an important element of flight instruction. It is the CFI’s responsibility to … Read more

Airplane Emergency Response Systems

Airplanes may have installed systems that provide alternatives in certain emergency situations. For example, ballistic parachute systems, if installed, may be deployed in an emergency allowing an airplane to descend slowly enough toward the ground such that occupants usually survive the resulting impact with minor or no injuries. Airplanes may also have an Emergency Autoland … Read more

Multiengine Airplane Training Considerations

Flight training in a multiengine airplane can be safely accomplished if both the instructor and the learner consider the following factors. The introduction, practice, and testing of emergency procedures has always been a sensitive subject. Surprising a multiengine learner with an emergency without a thorough briefing beforehand creates a hazardous condition. Simulated engine failures, for … Read more

Viewing the Airplane as an Energy System

The total mechanical energy of an airplane in flight is the sum of its potential energy from altitude and kinetic energy from airspeed. The potential energy is expressed as mgh, and the kinetic energy as ½ mV². Thus, the airplane’s total mechanical energy can be stated as: mgh + ½ mV² Where, m = massg … Read more
