=== Approach Speed set too low === | |||
Firstly it should be said that the stalling speed of the Mirage was set too low, as the 'approach speed' of the YASIM configuration file was set to 140 knots. The approach speed given in the Dassault company homepage is listed as 170 knots, and this is more realistic. | Firstly it should be said that the stalling speed of the Mirage was set too low, as the 'approach speed' of the YASIM configuration file was set to 140 knots.

=== Take-off and landing === | |||
Take off is straight forward, and the aircraft lifts off well and climbs at a shallow angle. Speed builds up quickly, but turning tightly at low level is hazardous as the aircraft will hesitate in a turn and then drop a wing in the opposite direction, without enough altitude in may be difficult to recover from the incident. Otherwise flying is easy and stable, but as in the real thing, speed bleeds off with idle power and gear down so approaches have to be fast and flat. The landing is performed with the nose not high, I attempted to change the approach angle to 20 degrees instead of 6 degrees and this caused all sorts of errors on loading. | Take off is straight forward, and the aircraft lifts off well and climbs at a shallow angle.

=== Instrumentation === | |||
Instrumentation is sparse, and oddly placed on a grey background that looks like it came from nowhere, I am in the process of changing this and improving the panel. The air speed indicator is a cryptically marked affair and the altimeter is dangerous to use. | Instrumentation is sparse, and oddly placed on a grey background that looks like it came from nowhere, I am in the process of changing this and improving the panel.

Using the head up display, especially one of the options using SHIFT+I will help fly the aircraft more accurately. | ||
=== Autopilot === | |||
Setting the Autopilot to heading bug mode and setting the heading bug on the indicator worked well, but wings level mode rolled the aircraft uncontrollably. Setting vertical speed hold resulted in rapidly diverging oscillations. | |||
=== Landing === | |||
Approach speed was at 200 knots, but if speed gets too low and power is increased, the aircraft will pick up so much speed that it will land at 200 knots which will probably burst the tires and run off the runway as well. One benefit of the Mirage is that there are no flaps to fail, so landing speed is always constant, depending on weight of course. The Mirage is loaded with fuel as default, reducing this to .40 fuel fraction ( meaning fraction of full capacity, not the fuel fraction in the engineering sense) helps lighten the aircraft but reducing below this fuel fraction results in the aircraft sitting on its tail. | |||
