So a daytime CAVU flight without at attitude indicator
is fine, because there's no way the primary attitude reference--the view out the window--could fail and require the AI.
The relationship between perceived empowerment and research attitude differed for both of the research attitude indicators
and provided only partial support for this study's third hypothesis that students who report a greater sense of empowerment will have a more positive regard for research.
There is very strong evidence, therefore, that the inclusion of worker attitude indicator
variables substantially improves the explanatory power of the model.
With the loss of the directional and attitude indicators
, pitch and bank must be inferred from the four remaining flight instruments.
However, that first block might also send its notion of what the airplane needs to do to track as selected, to "command bars" located on the attitude indicator
. This is the flight director and it can--in most installations--be on or off independently of the autopilot.
When I rolled wings-level, my instrument scan told me that my attitude indicator
was wrong because we were still turning.
The Cirrus we flew had the three-screen Evolution MAX backed up by an electric attitude indicator
, but Aspen told us the AI isn't needed if the MFD1000 in the suite has an external battery pack.
So, after the initial recovery, as soon as he moves his eyes off the attitude indicator
to cross-check power, confirm an independent attitude system or whatever, his hands distractedly move the airplane back to the wrong "up" again.
He few for two minutes with only the attitude indicator
working, before the airspeed and altimeter returned to normal.
Ever since we showed up for undergraduate pilot training, pilots have been taught to use the control instruments--the attitude indicator
and power instruments--to control the aircraft, and the performance instruments--altimeter, airspeed indicator, vertical velocity indicator, heading, and angle of attack scale--to monitor aircraft performance.
