De-ice/anti-ice

Question 1

We can do both de-icing and anti-icing in a one- or two-step process.
When should we use one or the other process, on what does that depend?

Answer 1

It depends on:
- weather conditions
- available equipment
- available fluids
- desired hold-over time (HoT)
But always use a two- step process as it cleans away fluid from previous flights
