Update for the 737

[Guest martyc]

Hello pmdg,I saw you've juste released the beech1900 and your on the way to give us the stretched version of the 737ng but :Please do not forget to add to your great first big work some minors update like the irs simulation wich should be so great and so important for a 737ng !Others little things to add should be :the aural warning when descending to a mcp assigned altitude (we have the climbing one)and a disengagement of the autobrakes when manually braking.But anyway a great thank you for your work !Christophe.
