"Ah, that'll be the great 'ZU' then!!"
Yep, ex KLM. Series 2000 aircraft (can tell by two overwing exits).
The Ham Std props have better performance at low level flight, which is why the P3 Orion has them fitted. The Aeroproducts prop is thought to be better in the cruise at altitude, which suits the role of the Electra at Atlantic Airlines.
Also, back on topic, well done to the crew
You can be my wingman anyday!
