B1900 speeds
Just for my daily fix of anal behaviour:
The B1900 AFM dictates that the aircraft can maintain 247 KIAS to FL132, decreasing linearly to 192 KIAS at FL250.
Sufficed to say in the interests of simplicity, when Dubai asks me what speed I can maintain in descent I say 220KIAS to FL130 thence 245. It averages out.
I know we're small fry at Dubai but every little bit helps!
