1. SI pressure units include certain units based on SI such as mmWa.

If <3airspeed> is selected, the type of airspeed unit must be selected. The display is:

Select <1calibrated> for airspeed calculated from

the differential pressure (Qc) assuming a fixed

altitude and air temperature (see Section 7.2 for

information on RPM4-AD unit conversions). This is

the most commonly used air speed unit.

<2true> for airspeed calculated from differential

pressure (Qc) taking into consideration altitude (Ps)

and a user entered temperature value.

If <2true> is selected, the default air temperature to be used in calculating airspeed must be

entered. The display is:

Entry field for default temperature to be used in true

airspeed calculation. The default value is 15 ºC.

Enter the default temperature value. This value can be edited when a true airspeed unit is

selected in the [UNIT] menu. Changing this value changes the default temperature value for

any true airspeed units that have already been setup.

In RPM4-AD displays, calibrated airspeed units are represented in lower case (e.g. kts)

and true airspeed units are represented in upper case (e.g. KTS).

If <4user> is selected, the user unit must be defined. The display is:

Entry field.

Enter the number of user units per Pascal (Pa) in the entry field. Pressing [ENT] defines the

user unit and returns to the <Set up unit #n> screen.

The user defined unit label can be customized to any alphanumeric, four character label

using the remote command "UDU" (see Section 4.4.4).

See Section 7.2 for information on the unit of measure conversions used by RPM4-AD.
