Hello Dynon its back again. Had a flight through the week in moderate sunshine and my EMS screen started cycling ie on/off several times in flight until i turned onto a new heading out of direct sunlight. To recap as suggested by you i have disconnected all switches and fuses and wired this...

Hello u guys I am in Australia from the 18th December until the 2nd Jan and was wondering if their was anyone available for a flight, me picking up the fuel costs of course. Life is too difficult for uk residents to get a permit to fly in Oz I will be based in the south of Brisbane and remember...

Hello Dynon, Many thanks for your response, and yes you are correct this only happens when there is direct sunlight on the screen, the other unit ie efis perform perfectly, i have tried on the ground bringing up the heat artificially inside the cabin enviroment to induce the problem with no joy...

had this problem going on a year now still no answers although it only happens when the screen is in direct sunlight which is not very often here but a pest in summer

fuzzflyer for whats its worth i had the same problem, changed sensors, renewed spade terminals at sensor heads etc with no joy only on further investigation further up the wiring loom there was a bad/dry soldered joint in the loom , resolderd and sensors are now solid, pig of a thing to find though

DYNON,given the troubles i am having with my EMS cycling off and on whilst in flight which continually drops out the autopilot, would it be possible to wire my AP74 to the D100 unit thats works.

Re: Cycling on / off  EFIS Screen Hello Dynon, Having sent the EMS back to the factory near on a year ago for a replacement and a year on i am still having the problem of the unit cycling on a warm sunny day. Is there anyone out there that can help me identify the problem, i have bypassed...

Hello Dynon I am pretty sure the torque is not set at 100 will check the setting of the torque next time up at the aircraft and set to 100 and report back thanks

Hello Dynon Meant to say the unit is a D100

Hello Dynon I have been following this thread as over the past month or so i have the occasional uncommanded turn severly to the left. On saturday of this week on a 3 hour flight the aircraft made 4 violent turns to the left whilst on altitude hold and track mode at various times thro the...

Hi Brantel Same remote compass in use, fitted for a while now which is spot on the mark with other readings although after software upgrade now that u say, the ticker tape seems "slack" thats the only thing i have noticed ie rolls left then right cant think what would cause that because...

Hello Again Dynon, Hope you can help, as in previous posts which were resolved after upgrading everything to the latest software version, i am now finding that when the AP74 is in nav mode it flies like an airliner spot on, when its in track mode it flies like an airliner spot on however, when...

Ham, many many thanks for the info it just stunned me when i thought everything had to go, can i ask was it much hassle to install the SV

ok Dynon many thanks for the info, if my first choice was to have a SV to replace the EFIS D100 what do people run along side it for an EMS as I currently have the D100 pilot side and the EMSD120 on the co-pilot side

Dynon or anyone maybe you can help, I was thinking on upgrading to the SV 7" to replace EFIS D100. My existing system is EFIS D100 and EMS 120, AP74, Remote compass, and heated Pitot. My question is can i just swap the D100 for the SV using the existing holder and using the exiting wiring/plugs??

OOOOOOOOOOOPS Sorry Problem fixed I think, had a quick flight to-day and all worked like a dream. The problem i think was the D100 was upgraded to the latest software without the AP being switched on so over the weekend we uploaded the new software with the AP switched on this time. Many...

you are correct in your assumption "Pressed and held for at least 2 seconds or more" whilst in level flight in 3 tries one after the other. If I understand your second point as i said earlier effectively when the AP74 button was pressed and held from a working state the AP dissengaged so I...

This occurence happened on Monday whilst i was in flight and the AP was engaged in track mode and altitude hold and was working fine for the duration of the 30mins or so flight, however when i pressed the button for a 180 turn this is when the AP disconnected, i pressed the button again on the...

Hello Dynon When pressing the AP 74 large button for 2 seconds for a rate 1 turn 180 the AP is turning off and perhaps it takes about three attempts before the AP stays on and the turn is then commenced any reason why this should happen.

Thanks Dynon did not think it would have made any difference to functionality but could have been a banana skin if one did not check as this is a retrofit, imagine carrying out the installation beleiving the manual DOH :'(
