(HUD) are common across most modes.
Required speed

Current IAS
Assigned altitude
Accelerometer
Current altitude
Aircraft datum
Director circle
Flight mode
Pitch scale
Bank scale
Artificial horizon
Distance to next waypoint
Figure 21: Su-25T Basic HUD Symbols
The aircraft datum in the center of the HUD rotates to indicate aircraft bank and roll.
A heading tape appears at the top of the HUD. Tick marks are labeled in tens of degrees
(e.g. the number "35" indicates a heading of 350 degrees).
To the left of the heading tape is the indicated airspeed (IAS). The assigned airspeed for
the next waypoint (depending on the operational sub-mode) is shown directly above the
IAS.
An accelerometer is displayed under the IAS in the form of a bar scale and triangular
marker. A marker to the right of center indicates acceleration; to the left of center -
deceleration.
To the right of the heading tape is the current flight altitude in meters. At altitudes less
than 1500 m above ground level (AGL), radar altitude is indicated with 1 m accuracy.
Above 1500 m AGL, pressure altitude above sea level (ASL) is indicated with 10 m
accuracy. The assigned altitude for the next waypoint (depending on the operational submode)
is shown directly above the current flight altitude.
