Above Ground Level or height. This is the actual height between the aircraft and the ground.
Abbreviation for AutoPilot.
Disregarding the following instructions leads to serious deterioration of flight safety.
Cylinder Head Temperature
Cylinder Head Temperature is measured by a temperature sensor in the cylinder head. It is an extremely important data, since it can prevent thermal damage to the cylinder (overcooling or overheating).
Density Altitude is the altitude relative to the standard atmosphere conditions at which the air density would be equal to the indicated air density at the place of observation. In other words, density altitude is air density given as a height above mean sea level
Exhaust Gas Temperature is the temperature of the exhaust leaving the engine. It is a direct indication of the combustion in the cylinders. The temperature probe for the EGT is located in the exhaust system very near the exhaust valve.
Engine Monitoring System
A portion of the Skyview with the engine data (temperatures, pressures and fuel) displayed.
Factor of gravity. It is used to express the apparent increase of mass due to inertia. While the actual mass of an object remains the same, during manouvering this object is apparently heavier. The G factor quantifies how much heavier.
A mass of a pilot is 80 kg. When manouvering at 3G, the pilot mass is still 80 kg, but the apparent mass that the seat has to carry is 3 (G) X 80 kg = 240 kg.
Galaxy Rescue System is a whole-aircraft-parachute that is deployed in an emergency by pulling an activation handle in the cockpit.
Ground Speed is the velocity with which the aircraft passes over the terrain. It is normally measured by GPS
The airspeed shown on the instrument(s). It is an almost direct representation of dynamic pressure exerted on the aircraft.
MAnifold Pressure is pressure in the intake manifold before the intake valve. It is a measure of how much the throttle is opened.
It is almost always measured in inches or mercury (in.Hg)
Combined with the RPM it provides the power setting information for a piston engine.
Maximum Take-Off Mass
The maximum takeoff mass also known as maximum takeoff weight (MTOW) of an aircraft is the maximum mass at which the pilot of the aircraft is allowed to attempt to take off, due to structural or other limits.
This mass is absolute and does not vary with atmospheric conditions, flap settings or anything else.
Outside Air Temperature
Temperature of the outside air measured by a probe on the aircraft.
Primary Flight Display
A portion of the Skyview with the basic flying instruments (airspeed, altitude, pitch, roll, sideslip, heading etc.) displayed.
Revolutions Per Minute is the measure of rotation speed.
If an object is turning with 2500 RPM it means it makes 2500 full rotations in one minute.
True Air Speed of an aircraft is the speed of the aircraft relative to the airmass in which it is flying.
The Venturi effect is a reduction of pressure in a fluid (gas or liquid) that results when this fluid flows through a reduced cross section.
The most typical examples of the Venturi effect in aviation are the carburators and older types of airspeed measuring devices (called Venturi tubes...).
Disregarding the following instructions leads to severe deterioration of flight safety and hazardous situations, including such resulting in injury and loss of life.
