Flight Instruments

Bought this to try. Could be very good but the numbers do not work well. Speed lags and changes seriously. Slowing from 60 to 30 and it still shows 60 a minute later. Altitude is also changing all the time and does not come near the Garmin GPS figures. Figures for ASI and Altitude are too small to read unless right in front of you and could be made bigger. If it worked better this would have been a 5 start application. I coudl not find a contact for the manuafacturer hence the detailed response.

Super junky, not even close to a reliable back up in my plane. I'm not sure what the use of this app is.

As a minimum, the speed and altitude display numbers need to be larger. Probably the heading could be larger, too. Recommend having an option under settings to select. Otherwise, a cool apt.

I wish I had checked other's reviews before buying. It does not work for flight. Too much vibration for the gyro I guess. I had my iphone Velcroed to the panel. Works while driving a car, but who need pitch/bank angle for driving? The free versions will do that.

This is a terrible and downright dangerous app. It can't tell a bank from a slip or skid. It also confuses acceleration and deceleration with pitch changes. I'm quite sure that if you tried to depend on this as a back up attitude instrument you'd be dead within a couple of minutes.

I'm an ATP CFI CFII MEI AGI and active professional pilot. I bought this for fun but it stinks even as an artificial horizon simulator. Does not hold a reference for wing level and must be caged constantly which defeats the purpose. I want my $5 back.

Will not hold level for more than 1 minute.

I knew when the iPhone 4 with gyros was announced it was only a matter of time before someone created an attitude indicator utilizing this functionality. There have been a few apps before like this but they do not use the gyros and only use GPS data. This app is amazing. I tested it out while flying; put it through all kinds of coordinated and uncoordinated turns, climbs, dives, slips and skids and the indicator behaved exactly like the real one in the cockpit. This app could save your life if mounted properly in the plane ahead of time. Note: don't buy this if you don't have an iPhone 4, you wont be impressed.

Great idea. A little frustrating that I had to be below 180kts and about 7,000' to get valid indications. Once up it was within 150' and 2 kts of the actual aircraft speed and altitude. In cruise it was precessing badly, almost unusable. That was at FL410 and an indicated .83 Mach. A landscape mode would be very desirable.
