Straight and Level flight Flashcards
when is a magnetic compass subjected to certain errors
-when there is turbulence
-during turns
-during acceleration and deceleration
-near the magnetic poles
when is the magnetic compass reliable?
when flying straight at constant speed
how often does the DG need to be readjusted
every 15min
when are compass errors more apparent
on headings of E and W
what does acceleration do to the magnetic compass?
indicates a turns to the north
what does deceleration do to the magnetic compass
indicates a turn to the south
would an updraft be considered an acceleration?
yes
would a downdraft be considered a deceleration?
yes
when is magnetic compass error most apparent when turning
through headings close to N and S
what happens to the magnetic compass when you turn in a N heading
indicates a turn in the opposite direction and lags
what happens to the magnetic compass when you turn in a S heading
indicates a turn in the proper directions and leads
what happens to the magnetic compass when you turn from E or W headings
-to the S = the more to the south, the more it leads
-to the N = the more to the north, the more it lags
