For an aircraft loaded with spray material or granules, an increase in density altitude results in:

An increase in density altitude refers to a situation where the air becomes less dense, typically due to higher temperatures, higher elevation, or both. This reduction in air density affects aircraft performance, particularly during the take-off phase.

When density altitude increases, the aircraft's engines produce less power because the thinner air contains fewer oxygen molecules for combustion. Additionally, the lift produced by the wings is also reduced since lift is dependent on air density. As a result, the aircraft requires a longer distance to reach the necessary speed for take-off.

This means that with an increase in density altitude, the take-off distance required for an aircraft loaded with spray material or granules will indeed increase. This understanding is crucial for aerial application operations, as pilots must consider these factors when planning their flights, especially in areas with high elevation or warm temperatures.
