Fligh Calculator front side

The flight computer IWA-11092 was developed especially for aspiring pilots and is unbeatable in its simplicity and reliability. All calculations for flight preparation and flight control can be done with the scales on the front side. A new scale arrangement allows all correction steps from IAS to CAS, EDS and DAS to TAS to be carried out with a single adjustment to the disk and the cursor. This even connects to the correction of the error caused by the compressibility of air.

Further on the aviation calculator enables reading and calculations for all requirements before and during flight, as for example route and flight time, speeds, climb, descent, course connections and no return point as well as many others. Clear settings are provided to convert all common units.

Flight Navigator back side

The back face is for navigation with the wind triangle methods: Direction and speed vectors of wind and aircraft give a vivid picture of all your manoeuvres and the corresponding position of your aircraft. The wind and ground speeds as well as coupling a number of legs are easily calculated.
Speed ranges on the two chart boards: 20 - 200 and 150 - 750 km/h, mph or knots.

In aviation, absolutely reliable and safe navigation aids are vital. Thus, mechanical calculators and navigation devices have claimed their place next to electronics, because they offer constant availability, without any risk of failure due to depleted energy sources or technical defects.

In pilot training

Right from the beginning of your training, you will work directly with the flight computer IWA-11092 and love it for its simplicity, precision, and ease of use.
