User reviews

Super nützlich

Klasse App. Spätestens seit einem die Flugleiter nicht mal mehr das Q NH sagen dürfen, würde ich sie nicht mehr missen. Zu bekomme ich immer das nächstgelegene QNH angezeigt.

Wetterradar unterwegs super nützlich mit kurzen Intervallen. Besonders in Verbindung mit Starlink Internet (aber natürlich auch mit mobilen Daten) unverzichtbar. Ein GameChanger.

Tests in flight

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.

Response from developer

Thanks a lot for this fair review!

Excellent Value

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

Response from developer

Thanks a lot! Some improvements coming soon! We just added the German „ADL“ satellite wx receiver that also has an AHRS and i would love to add more devices. For this i need pilots who own these devices, so we can test the integration. Please write via my website www.airwork.biz Will try to solve the mentioned problems asap!
