Subject: Re: [LML] Re: Legacy Canopy Down & Latc.. 

To all:

I have asked the builders I have done work for to incorporate a canopy  
lever micro switch for some time.  I incorporated the switch in my own  
Legacy from day one.  I order to get past the issue of light vx. horn,  
I used the concept of "Lights Out."  This is a concept that is used on  
most modern aircraft today.  Before you take the runway you configure  
the aircraft for takeoff.  Important systems (flaps, trim, fuel, fuel  
pump, canopy) have either check list, annunciator lights, or both to  
indicate proper position.  Once the aircraft is configured all lights  
are out.  So on takeoff you should not see any light.

These accidents bring up a more important issue that is being glossed  
over.  The Legacy flies fairly well with the canopy open.  Aviation  
safety is in most cases a state of mind and an issue of planning and  
prioritizing.  When things go bad ( which will happen to every one at  
one level or an other), you have to immediately start prioritizing.   
But prior to any of this, a pilot must know his craft.  You have to  
ask yourself what will I do if this (ie. canopy pops open on takeoff)  
happens to me!  When something happens, you have to switch gears and  
go into survival mode.  In the example item prior, fly the plane,  
screw the noise, screw the stuff flying around the cockpit, stay calm,  
and make good decisions.  If you keep flying the plane and get past  
the oh no or what if, im most cases you will come out ok.  Deal with  
what you have, its normally not that big of a deal.  A good example is  
an engine failure on takeoff in a single engine airplane.  If you  
don't know exactly what energy state is required to return to the  
airport (because you never tested this, glider pilot 101) you go  
strait ahead and start thing about what will allow me to live.  Screw  
the airplane.  You are going to need energy to touch down, anything  
less is death or worse.  The morel of the story, fly the plane to the  
landing at the proper speed and under control whether planed or  
unplanned.  Their is no difference.  It's all about prioritizing.

Reducing the loss of life in these types of airplanes is up to us.   
Just my 2 cents.  Sorry for being so intense but we need to shift our  
mind set.

Bill,

I failed to mention... it's a BIG RED light.  If I miss that, I  
shouldn't be flying.

     If you are going to do something like this, I suggest that you  
incorporate the microswitch on the canopy with the throttle position  
so that a horn or buzzer goes off if the throttle is advanced beyond  
taxi position with the canopy not down and latched.  A light could be  
missed on take off until too late, but a horn would not.


     Oh, if you design something like this, let me know how you did  
it!  :>)
