Hope you don't mind I did.

Question 9 and higher have been added later
1) I want to jump with a vigil over here. Is that possible
http://www.cfcenter.co.il/dsinfo.htm
No problem, all the vigils delivered at the moment can be programmed till a pressure of 1090mbar, this means till-500m. All the Vigils model B en C can be reprogrammed from 1035mbar to 1090mbar free of charge
Ok from issue D you can, where can I find this issue on the box (sticker, embedded). AAD only does the reprogramming free of charge all extra cost will not be covert (shipping repack if required)
2) Leaving from skydive Spa (±1500ft altitude) I want to make a jump-in at texel (at the sea) (About 2 hours flying). Is this possible, how do I adjust the vigil ?
Of course you can. Make a re-adjustment of– 1500ft).
Ok, I did not expect a different answer. I can look up in the manual how to re-adjust
3) Which aerospace-specifications have been used to qualify this equipment for the aerospace-autority like EMC and environmental
The toughest specifications. The Vigil is tested at a recognised lab (Denayer, Mechelen) till 100V/m with perfect results.
The 'toughest specifications' does not clarify anything for me. I'm sure the vigil is NOT tested according to the toughest aerospacespecs. The toughest case is (direct) lightning strike. I would have expected an answer like : MIL-..... or DIN-.....
I consider this question still open.
4) Do the electronic components comply with aerospace quality?
The electronic components used are professional quality and have a life expectation of 20 years.
Please answer YES/NO, If no why didn't you use this quality.
5) No equipment lasts forever(Ask the more exoperienced videojumpers)
What is the life expectation of the vigil usage about 100-150jumps a year. Take into account the severe environment (temperature differences, shocks and moisture).
Vigil does not last forever. We give an “Expected Life Time” of 20 years Majik making upto 500 jumps a year can use the vigil 20 years without problems
At Parachute the france 2 vigils are still functional after a 500m drop.
This is Vigil.
An expected lifetime is an expectation.What does vigil if this turns out to be for example 10 years for whatever reasen?
6) A little more technical: A dual square situation can be geklassificeerd as dangerous ( No discussion about that) Is it possible due to a software error(Single software failure) to switch from pro to student or tandem mode?
This is absolutely inpossible. One in a specific mode this may only be altered with the pushbutton during startup..
I'm sorry, have you ever heard of 'bit-flip'
7) How can a company without experience in the aerospace industry give a statement 'no maintenance required'. All components age, even solderconnections age.
At each start-up the vigil checks all functions, in case something is wrong with the batterie, cutter or electronic parameters, the vigil will not start and the vigil has to be returned
And in case the pressure sensor ages? On the ground this is not notified, but as the pressure drops (during climb) the altitude sensing gets less accurate.
It seems clear your company bets on 'on condition' maintenance instead of 'preventive' maintenance. This is very dangerous in a safety critical application
8 ) How did you solve the issues reason for the grounding in germany?
Look at our answers at “Dropzone.com”
At dropzone.com I can find some answers, but I can not find anything about the poti for example
New questions:
9) During development have you performed a FailureMode-EndEffect analyse If not I would suggest to perform this.? Please do not answer something like 'we did a lot of tests"
Following questions come from a swedisch investigation .Mentioned on www.dropzone.com:
10) What is the accuricy of the unit? ±80m is not always achievable. By the way 225m-80m=145m Little low seems to me.
11) Is this true ?
We recently did some tests on the scenario when you adjust for
a *higher* landing altitude and the Vigil cannot handle that
correctly either. The Vigil appears to have a problem knowing
where the "zero-level" is when you do these types of adjustments.
For example, if you adjust the unit to a landing altitude that
is, say, 300 meters above your take-off altitude. Fly up well
above this altitude but cancel the jump (clouds!) and go back
down with the plane. The Vigil then fires when you pass the
300 meter level (intended landing site) if you exceed only 20
m/s in descent rate.
12 ) Is this true ?
The problem with sensitivity to electrostatic discharges may
have been solved but there are still other issues with the
electronics construction that we think are sub-standard.
For example, the fact that the manual says that the unit can get
stuck in some state where you have to open the unit and tempo-
rarily remove the battery in order to make it work again.
This is kind of like rebooting your computer by unplugging the
power supply and indicates an electronics design that is flawed.
13) Please comment
AAD says that they are constantly improving the design and fixing
any problems. However, with no mandatory service interval there
is no procedure for updating all units in the field. With the
exception of the total recall this spring due to a severe problem
with sensitivity to electrostatic discharges, a unit that is out
there does not get updated.
14) With a vigil equipped rig can I jump in austria or sweden?
