Hi,

 

in the FCOMv1 page 17 it says for 737's without stiffened elevator tabs:

 

"After any ground deicing/anti-icing of the horizontal stabilizer using Type II or Type IV fluids, airspeed must be limited to 270 KIAS until the crew has been informed that applicable maintenance procedures have been accomplished that would allow exceedance of 270 KIAS. Once the applicable maintenance procedures have been accomplished, exceeding 270 KIAS is permissible only until the next application of Type II or Type IV deicing/anti-icing fluids."

 

Does anyone know, why they limited the airspeed after use of thickened deicing/anti-icing fluids?

Hmm it has something to do with the fluid getting into areas where it shouldn't be. I forget exactly what the problem is with it. The maint action is removal of the fluid from places it shouldn't be.

 

Best regards,

Robin.

This is purely academic in the context of the NGX and FSX though...
