Take off distance will increase.

Take off available will increase.

Take off distance remains about the same because the increase in temperature cancels out the effect of the

increase in pressure altitude.

Take off distance will increase by a small amount because the increase in pressure altitude reduces the

effects of the increase in temperature.

Reference stall speed in a specific configuration.

1-g stall speed at which the aeroplane can develop a lift force (normal to the flight path) equal to its weight. 

Reference stall speed in the landing configuration.

Stall speed or the minimum steady flight speed obtained in a specified configuration.

The speed at which onset of natural stall warning occurs with the aeroplane NOT exceeding 1-g conditions.

The stall speed or the minimum steady flight speed at which the aeroplane is controllable in 1-g conditions.

The 1-g stall speed at which the aeroplane can develop lift equal to its weight.

The speed at which onset of artificial stall warning occurs with the aeroplane NOT exceeding 1-g conditions.
