I would like to answer the question regarding climb speed.
The AFM of the Dash 8 differentiates between 3 types of climb.
Type one: Highspeed with 195 kts. This one will be used if a flight is behind schedule. It results in a higher speed at low flight altitudes. Starting at FL 120 the pilots would have to reduce speed gradually to 163 at FL 180, above the same speed schedule as for Type 2 applies. With this climb you can make up 4-5 minutes on a flight.
Type two: 165 kts will be kept until FL 180. Here speed is gradually reduced in steps until reaching FL 250, where you would only have 135 kts. This reduction above FL 180 is necessary as the perfomance of the aircraft drops significantly and the aircraft would not climb any more with 165 kts at higher weights. Remeber that according to the Climb power table the torqe has to be reduced above FL 120 at normal OAS. This causes a poor climb rate at higher altitude.
Type 2 climb is the normal climb schedule for the Dash 8 and most oeprators use it.
Type three: The low speed climb is flown with a speed of 135 kts up to FL 250. This gives you a great climb speed an angle, however, results in a high pitch which normally makes a in flight service of the cabin attendants a challange. Hence, it is only used for terrain/weather clearance.
Climb is normally flown with 1050 or 900rpm. 1050 gives you a better climb rate, but also more noise.
The manuals give you tables for Type 1-3 Climb and with either 900 or 1050 rpm. However, this does not mean that you have to stick to those tables. You can always fly it like a cessna, its just that you don´t have any performance tables when deviating from the stated procedures. Especially in turbulence we use to climb in pitch mode (5°) to avoid pitch oscillations with IAS mode, and the speed is up to the weather.
I hope that helps. Greetings to all fans of our product.
