Electronics International MVP-50P - Manual (Page 65)

Airspeed (indicated airspeed) and TAS:
Airspeed calculations are based on a NASA equation. True Airspeed will be displayed when the follow-
ing is true:
1. Pressure Alt is provided.
2. OAT is provided
Notes: If Indicated Air Speed is required in the place of TAS, select IAT function to be displayed.
Recovery Factor:
Recovery Factor is used to calculate Corrected OAT and True Airspeed (TAS). The Recovery Factor
compensates for airspeed, altitude, OAT probe design and OAT probe placement. The setting is be-
tween 0 and 1.99, with 1.0 being the average setting for most configurations. The Recovery Factor is set
to produce no change in the OAT between slow flight and fast cruise.
Horsepower (MVP-50P):
Horsepower is based on the RPM, MP, EGT, Altitude and a Calibration Factor. Reference values are
entered into the “Horsepower Calibration” screen.
Horsepower (MVP-50T):
Horsepower is based on (Np x Torque) / Calibration Factor. The Calibration Factor is entered in the
“Engine Data, .... Setup” screen.
Torque (MVP-50T):
Torque is measured via an E.I. pressure transducer. Torque can be displayed as pressure or a percent-
age. The “Engine Data .... Setup” screen is used to calibrate Torque.
Shock Cooling (MVP-50P):
The Shock Cooling rate is calculated from the CHT readings for each cylinder. The highest Shock
Cooling value is displayed.
Bar Graph (Lean Operating Mode, MVP-50P):
Once the Lean Operating Mode (LOP or ROP) is entered, an EGT must drop 3’F below its current
peak to display a Peak Marker. If the EGT for a channel that has reached peak increases 3’F above its
current peak, the Peak Marker will be turned off and a new peak will be established (this is a false peak).
In the Lean ROP mode, only the first EGT channel to reach peak will display a Peak Marker. In the
LOP mode, every EGT channel that reaches peak will display a Peak Marker.
Bar Graph (EGT Max Limit Line, MVP-50P):
If the following conditions are met, an EGT Red Max Limit Line will be drawn:
1. The “Cylinder” field in the “EGT/CHT Bar Graph Limits and Color Setup” screen must be set to
“ALL” for the EGT function.
