AIR File - Steerable Aircraft

I

Ivan

SOH-CM-2025
Hello All,

I have been trying to rework the AIR file on my P-40E to make the aircraft steerable on the ground. Unlike most tail wheel aircraft, the P-40 (and P-51 as well) has a tail wheel which is linked to the rudder and will allow the aircraft to be steered on the ground. Most tail wheel aircraft can only use prop wash on the rudder to effect steering. The tail wheels are mostly fully castoring. Locking tail wheels are not simulated in CFS1.

What I found was that setting the variable for "Steerable" in Record 1004 had no observable effect even though the variable obviously changed values as confirmed by a hex editor, FDE, and AirEd.

What I was able to confirm yesterday and this morning is that the description of this value is incorrect. It is normally set as BOOLEAN4 in both AirEd and FDE but should instead be INTEGER4.

BOOLEAN4 values are True and False
True = FF FF FF FF (hex)
False = 00 00 00 00 (hex)

INTEGER4 values SHOULD be 1 and 0
Steerable = 00 00 00 01 (hex)
Non-Steerable = 00 00 00 00 (hex)
Boolean True = FF FF FF FF (hex) - Has same effect as non-steerable.

Hope this helps someone out there. This is probably the first useful thing I have "Discovered" in AIR Files.
- Ivan.
