Also for those that have sims coming up, i found that using the 737-800 cockpit on flight sim x was the most accurate representation of the Q400. Just fly the approaches on flight sim with the autopilot and do it over and over again, that way u will have good situational awareness and will memorise altitudes. You can click on the 2 primary instrument displays to make them bigger, then drag the corner of each to the sze u prefer.
