A method of providing power information in a rotorcraft, the rotorcraft having a powerplant, the method comprising: calculating, by a calculation unit, a real-time power required, comprising: recording a data associated with a variable, the variable including at least one of: a real-time weight of the rotorcraft, a real-time outside air temperature, a real-time pressure altitude; under default conditions, processing the data using hover performance information based upon out-of-ground effect performance data; and allowing a user to instruct the calculation unit to process the data using hover performance information based upon in-ground effect performance data; calculating a real-time power available, comprising: conducting a power assurance check resulting in a power assurance data; determining an amount the powerplant is above or below min-spec criteria; recording information associated with a measurement of a variable that affects power available; and processing the information using powerplant performance information; orienting a power required indicator on a power safety instrument, the position of the power required indicator being dependent upon the calculating of power required; and orienting a power available indicator on a power safety instrument, the position of the power available indicator being dependent upon the calculating of power available. calculating, by a calculation unit, a real-time power required, comprising: recording a data associated with a variable, the variable including at least one of: a real-time weight of the rotorcraft, a real-time outside air temperature, a real-time pressure altitude; under default conditions, processing the data using hover performance information based upon out-of-ground effect performance data; and allowing a user to instruct the calculation unit to process the data using hover performance information based upon in-ground effect performance data; recording a data associated with a variable, the variable including at least one of: a real-time weight of the rotorcraft, a real-time outside air temperature, a real-time pressure altitude; under default conditions, processing the data using hover performance information based upon out-of-ground effect performance data; and allowing a user to instruct the calculation unit to process the data using hover performance information based upon in-ground effect performance data; a real-time weight of the rotorcraft, a real-time outside air temperature, a real-time pressure altitude; under default conditions, processing the data using hover performance information based upon out-of-ground effect performance data; and allowing a user to instruct the calculation unit to process the data using hover performance information based upon in-ground effect performance data; calculating a real-time power available, comprising: conducting a power assurance check resulting in a power assurance data; determining an amount the powerplant is above or below min-spec criteria; recording information associated with a measurement of a variable that affects power available; and processing the information using powerplant performance information; conducting a power assurance check resulting in a power assurance data; determining an amount the powerplant is above or below min-spec criteria; recording information associated with a measurement of a variable that affects power available; and processing the information using powerplant performance information; orienting a power required indicator on a power safety instrument, the position of the power required indicator being dependent upon the calculating of power required; and orienting a power available indicator on a power safety instrument, the position of the power available indicator being dependent upon the calculating of power available.
