The BEST performance will occur when the outside air temperature is high and the pressure altitude is low.

The WORST performance will occur with a combination of low outside air temperature and low pressure

altitude

The WORST performance will occur with a combination of high outside air temperature and high pressure

altitude.

The BEST performance will occur when the outside air temperature is low and the pressure altitude is high.

Max Range, because this speed corresponds to the maximum lift to drag ratio at the minimum.

Max Endurance, because fuel flow is proportional to thrust at the minimum.

Max Endurance, because fuel flow is proportional to power required.

Max Range, because fuel flow is proportional to lift to drag ratio.

Extending flaps during the descent results in a smaller Best Glide Angle.

A lower altitude allows for a higher speed while maintaining the same Best Glide Angle.

A higher mass allows for a higher speed while maintaining the same Best Glide Angle

A tailwind component increases the Best Glide Angle for a given speed.
