6.9.9 Set Alt & IAS Offset
Modern digital sensors that are used for the IAS and altitude measurements may drift a little bit over time,
especially after exposed to a prolonged period of severe cold. The window shown on Figure 30 allows
appropriate adjustment.
•
Altitude: Change the offset until the altitude below the offset frame matches the reference altitude
(Alt) or static pressure (SP). The reference values are obtained using a reference altimeter set to
1013 hPa.
•
Airspeed: Change the offset until the differential pressure shows zero.

6.9.10 Set MAP & Fuel Flow Offset
This window allows offset of the manifold pressure sensor and fuel flow correction factor.
•
Manifold: Adjust the offset until the MAP value is the same as the SP (static pressure). Both
values are shown below the adjustment rectangle. (With engine stopped, the manifold sensor reads
the static pressure.)
•
Fuel flow factor: This factor is used to correct the software fuel flow correction model. Setting
value more than 1 increases indicated fuel consumption and vice versa. If fuel flow sensor is
installed this factor has no effect.
