APU use landing on Contaminated Rwys
The reason for this has been lost in history somewhere but our company's A320 SOP winter supplement suggests "consider use of APU and CONT IGN when landing on contaminated runways. (This is before touchdown)
CONT IGN is obvious but why APU and for what purpose?
- I thought that perhaps it presents a lower risk of ingesting runway de-icing fluid into the A/C with BLEEDS on APU but then why not just state BLEEDS on APU?
Any thoughts on what I'm missing here?
