Is This An-24 Startup Unusual?

Sat Mar 10, 2012 4:13 pm

I saw this video of an Antonov An-24 airliner having someone literally spraying the propellers and engine intake during engine startup at Chita Kadala Airport (IATA: HTA) in probably very hot weather:

Is this normal practice to start a plane like this?

We discussed this not long ago:

Quoting KPWMSpotter (Reply 8):
I've read before that the Antonov turboprops were notoriously hard to start on hot days, and a common solution was to spray cold water at the inlet to cool the engine. I'm not sure how true this is, but it almost makes sense - you can get an extra boost of power from the ingested water, almost like water injection on the early turbojets.

This photo shows a similar situation, with a brief description.
