WARNING:
To get a precise indication of the air speed, some scales are
"stretched". Please note the
different resolutions
of the scales. The
increment between two marks can indicate speed differences from 2.5 km/h to
10 km/h!
Example:
ALPHA
ALPHA
ALPHA
ALPHA
MFD
version B (340 km/h) uses the following "stretching scheme":
•
From 60 km/h to 110 km/h every mark indicates a speed resolution of 2,5 km/h
(important for precise indication of speed for landing or to prevent stalling)
•
From 110 km/h to 210 km/h every mark indicates a speed resolution of 5 km/h
•
From 210 km/h to 340 km/h every mark indicates a speed resolution of 10 km/h
Additional details in section 11 "Technical data"
In SET-Mode 17 two different pointer styles can be chosen according to personal
preferences: Sectional pointer or single pointer. More in section 4.4.1 and 4.4.2
Because it is very important to comprehend the different speed ranges at a single
glance, self adhesive coloured marker rings in white, green, yellow and red are
included with every
ALPHA
MFD
. These rings can be mounted to the speed indicator
corresponding to the speeds of the individual aircraft (Vno, Vne, Vso, Vs1, etc.)
4.1.3 Stall-Alarm
Stall-Alarm:
In SET-Mode 6 the visual and audio warning for stall speed in landing
configuration (Vso) can be programmed. After switching to SET-Mode by pressing the
>
FUNC/SET
< key (SF = special functions) for a few seconds, select SET-Mode 6 =
STALL ALARM by pressing the >ARROW<-keys. After pressing the >
ENTER/MEMO
<
key the <SET< icon will start flashing. Now the speed of the stall alarm can be
adjusted. By pressing >
ENTER/MEMO
< again, the new value is stored. Pressing the
>
FUNC/SET
< key leaves the SET-Mode. To change the value for stall alarm can be
blocked by the aircraft manufacturer.
