Svt Unusual Attitudes; Dead Reckoning - Garmin Beechcraft 200 Series Cockpit Reference Manual

Abnormal Operation

SVT UNUSUAL ATTITUDES

During extreme pitch attitudes, the display shows either a brown or blue colored bar
at the top or bottom of the screen to represent earth or sky. The blue colored bar is also
displayed when terrain gradient is great enough to completely fill the display. This is
intended to prevent losing sight of the horizon during extreme pitch attitudes.

DEAD RECKONING

NOTE: Dead Reckoning Mode only functions in Enroute (ENR) or Oceanic
(OCN) phase of flight. In all other phases, an invalid GPS solution produces
a "NO GPS POSITION" annunciation on the map and the system stops using
GPS.
While in Enroute or Oceanic phase of flight, if the system detects an invalid GPS
solution or is unable to calculate a GPS position, the system automatically reverts to Dead
Reckoning (DR) Mode. In DR Mode, the system uses its last-known position combined
with continuously updated airspeed and heading data (when available) to calculate and
display the aircraft' s current estimated position.
It is important to note that estimated navigation data supplied by the system in DR Mode
may become increasingly unreliable and must not be used as a sole means of navigation.
If while in DR Mode airspeed and/or heading data is also lost or not available, the DR
function may not be capable of accurately tracking estimated position and, consequently,
the system may display a path that is different than the actual movement of the aircraft.
