iEFIS Pro

IEFIS PRO was PERFECT during a 3 hour flight in my Lance. Airspeed was perfectly aligned with my Garmin 430. Attitude info matched my panel mount horizon, bank by bank. Climbing attitude matched perfectly as well. The disclaimer rightfully says it is NOT intended to be relied on as a PRIMARY flight instrument, and as its reliability DEPENDS SOLELY the internal gyros of your iPad or iPhone, I wouldn’t say it was a bulletproof backup AHRS. Plus, I did NOT TRY to make it tumble, by performing a very steep turn. But, if you lost your vacuum in IMC, and needed to get your wings level in a hurry to start a gentle decent from the soup, imho, you would be pretty happy to hav this little app onboard. It performed as advertised. I’ve been told that iPhone internal gyros do tumble in extreme attitudes, so let the buyer beware. Personally, I really like this little app, for what it MAY do to save your bacon, when you are out of other options. Just my opinion.

Useful cockpit app. Great presentation with altitude, speed heading and attitude all functional. Most useful tool is constant update of nearest airport giving distance, direction and runway info at a glance. Some suggestions: 1) program app so screen doesn’t time out and shut off 2) portrait only - allow landscape 3) work with open source products such as Stratux AHARS and other ADSB in products
