 Posted: Sun Oct 08, 2006 5:37 am Post subject: backup instrumentation/lost in EFIS |
 |
|
I have thousands of hours of EFIS time, and hundreds of hours of HUD
(heads up display) time, so feel qualified to comment on this subject.
EFIS-B737/757/767/777, if it matters. HUD-AH-64A and B737-800, ditto.
Since 1987, ditto.
Commonalities, trends, frequent observations...It is easy to get "lost"
in the display and it's symbology, whether HUD or EFIS. Solution, among
others, learn what each symbol, tape, vector, everything means, how/why
it might change mode or appearance, etc., before you really need it in
day VFR, not to mention night VFR, or especially true IMC IFR flight.
This education process starts with the manual, calls to manufacturer or
other users, perhaps formalized unit specific training, etc. Do NOT try
to just "muscle" your way into using an EFIS, or any electronic display
for that matter, without a thorough understanding of what it's trying
to/should be/is telling you. If it takes a trip to Flight Safety, etc.,
to get some EFIS time in a simulator, so be it. Money well spent.
Remember, we do not have a BRS (parachute) like the Cirrus, if the
display or our brain blanks. When transitioning to a new EFIS/HUD, I
have found it helpful to initially focus attention on the display
center, i.e. pitch/roll attitude, and the basic flight info i.e.
airspeed/altitude. Then, as comfort level and proficiency level
increase, if they do, work outward to include other less critical
flight/other info. I have seen it demonstrated, repeatedly, that some
pilots, regardless of age/experience, young and old, just never become
comfortable, proficient, with electronic flight information displays,
and just should stick with round gauges. It even follows that some
pilots should stick with day VFR, out the window flying, in slower, more
forgiving airplane designs, than RV's. JFK Jr. a C172 in day VFR??
Others? I hope the analogy is clear. Find your own niche.
Training with EFIS and HUD displays, at least in military and airline
settings, nowadays, ALWAYS begins in the simulator, where the force of
the hydraulic motion servos is nothing compared to what the ground feels
like when you hit it hard. Hope this is food for everyone's thought.
Back to obscurity, and being just another poster/reader of this valuable
list/forum. Thanks to the moderator. And, sorry, but the comment re
airplane with an EFIS, but primarily flying by round airspeed/altitude
gauges, really got my attention. Humble apologies.

I agree with the previous comments..............at Oshkosh I was able to see and Play with several of the EFIS brands. One thing that was very helpful was the DECLUTTER feature some of the brands have on them. It is very similar to that found of several GPS units................you can remove overlays of information from the screen to just show the BASICS if you want. For example, if the EFIS is showing 10 instruments on the screen..........declutter/remove all of them except ASI/ALT/COMPASS/ATTITUDE. Now you have only 4 things to observe and process in your brain. As one gets used to seeing these you can slowly add in a few more at a time. I know when I look at some of the screens people are flying behind I ask myself,"What are all those numbers/arrows trying to tell me. Keep it simple to begin with........especially in VFR we really don't need to overwork the panel guages. Enjoy the view and FLY THE PLANE.
just my .02 worth.

Now the monocle on the AH-64 must have been REAL fun to get used to.

Link,
Welcome, and good post. I think a lot of people expect to jump into
an aircraft with an EFIS and immediately be able to go into any
conditions because of the whiz bang features that are supposed to keep
them out of trouble. As long as people remember to aviate before
anything else, they will hopefully stay out of trouble.
Oh, and there are no moderators on this list. It is 100% wide open,
community policed. Unlike someone else that has all of his forums
strictly moderated, the Matronics lists have long since proven that
these mini societies are just fine without someone imposing their ideas
of what are right or wrong.
