Great addition Milton and Team. Thanks very much.
My flying style is to start with Ctrl-E, taxi and takeoff and then check in with Seattle Control. If you want ground control and the nearby ATC to recognize you properly, here's what I did.
First, I changed the [General] section to look like this:
[General]
atc_type=Grumman
atc_model=G73
visual_damage=0
atc_heavy=0
performance=
editable=1
category=airplane
Specifically, I added the lines highlighted in red. The type and model are standard for FSXA. Once airborne you will be recognized as a Grumman Mallard. The existing entry (atc_type=G-73) is not recognized by FSXA, so that needs to be replaced.
Second, I modified each of the [fltsim.xx] entries. I completed the "atc_id=" line with the tail number (or whatever you wish) as shown below, highlighted in red:
[fltsim.7]
title=Mallard N2974 Chalks
sim=MallardMS
model=Modfsx
panel=
sound=
texture=N2974
ui_manufacturer=Grumman
ui_type=G-73 Mallard Modern
ui_variation=N2974
ui_typerole="Twin Engine Prop"
ui_createdby="Milton Shupe and Team"
atc_airline=
atc_id=
N2974
kb_checklists=G-73_check
kb_reference=Mallard_ref
description=Model by Milton Shupe; FDE by Airwrench and me; sounds by Nigel Richards, Textures by Toni Hiltunen
This change in combination with the changes to the [General] section will enable FSXA to recognize me as Grumman N2974 to ground control.
For me these minor tweaks adds to the realism of a really need aircraft. Thanks again.
