FoxMike Posted December 10, 2015 Report Posted December 10, 2015 If you are having a difficult time finding an appropriate gift for your aluminum mistress you might consider this Sandia 340. Each function meets an appropriate TSO and the instrument is recently certified to be installed in factory airplanes. The install took about 2.5 hours. Initially it added to the pilot workload but it is not something you need to more than scan occasionally. Your Mooney will love you for it. All the details are on Sandia-aero.com. Quote
Houman Posted December 10, 2015 Report Posted December 10, 2015 Stupid question as I'm not an A P, but would you get the pitot and static input from the pitot and static lines coming into the primary instruments on the pannel ??? Just wondering. Quote

Where did you get it? Aircraft spruce says it will available by Jan 20th. I can't wait to get it . Thansk. Quote

FoxMike Posted December 10, 2015 Author Report Posted December 10, 2015 MooneyBob is right you have to cut the static and pitot lines and tee them. Requires a leak check. I found the unit at Depot Avionics in Alamosa, Co. I think Sarasota Avionics has stock or at least they did several days ago. 1 Quote
carusoam Posted December 10, 2015 Report Posted December 10, 2015 FM, I'm looking forward to the real life side by side comparison... As measured by your eyes. If the old analog gauges merit looking at, after the brain and eyes get used to taking in all that data from one place. for some people it probably takes a flight or two. Some maybe even less... Are you more a numbers guy or picture guy? Good luck leading edge guy, -a- Quote
FoxMike Posted December 10, 2015 Author Report Posted December 10, 2015 Have flown about 3 hours with the SAI340. I am not a fan of speed tapes so I look mostly at the steam gauges. The artificial horizon of the 340 is a bright snappy presentation which I like to monitor. I tried a landing using the airspeed tape for reference. The dial gives me more meaningful data. 2 Quote
MooneyBob Posted December 11, 2015 Report Posted December 11, 2015 I am definitely the handle guy. The handle position gives you instant visual reference. You don't have to translate those numbers. I have tried to practice emergency procedures with AI on my iPhone from Garmin Pilot and the fast changing VSI numbers drove me crazy. I had tendency to overcorrect and overcontrol everything. This Sandia will be my backup instrument and since it includes all vital parameters plus battery backup it should be a great addition to the safety improvement in case of emergency. And my turn coordinator just died. Quote
bradp Posted December 11, 2015 Report Posted December 11, 2015 Bob could you show a video of this thing in action? Looks great. Brad Quote

OR75 Posted December 15, 2015 Report Posted December 15, 2015 I will be curious to see a video of it operating in particular during the take off roll. Reason I ask is that I had heard the RCAllen 2600 series had a lag during acceleration. Also interested to see if it is sensitive to vibrations ... since you have a J ... how does is react as you go through that dreaded RPM yellow arc Quote
kevinw Posted December 16, 2015 Report Posted December 16, 2015 Looks great. I have one on order and just waiting to get into the shop for install. I'm pulling the vacuum system and standby at that time as well. Very interested to see how much useful load I'll gain. I'm hoping for 8-10 lbs but that may be wishful thinking. Keep us posted on how you like it and if any issues arise. -Kevin Quote
carusoam Posted December 18, 2015 Report Posted December 18, 2015 OR, AIs are sensitive to acceleration down the runway. They perceive it as if they were pointing up slightly. your back perceives the same thing as you get pressed by 310 horses into the back of your seat. Kinda feels like pointing towards the sky does. heavy braking would have the opposite effect. would an electronic AI filter this effect out? Using WAAS data it could calculate the acceleration and remove it from the display. using the word 'lag' would mean something different? This topic gets covered under the limitations of instrumentation when studying for the IR. I have yet to notice the AI doing anything odd because I am so busy looking down the runway and at the ASI in such a short period of time. the heaviest part of the acceleration only last 5-10 seconds(?) hardly enough time to reach steady state for most instruments. I am looking forward to the electronic revolution of my IP. It is going to take a long time.... Best regards, -a- Quote
