"That means every second on the circuit counts, and I have to be consistent as well and quick - and of course stay out of the way of any incidents that occur."
Armstrong says he doesn't feel any additional pressure this weekend and is focusing on honing his skills and insight into single-seater racing.
"Naturally, my own expectation is higher, and my dad will be watching this weekend - no pressure - but I'm trying to approach this weekend as I did the 'Ring."
Armstrong has been racing karts in the KZ category all year in Europe, and returned to karting after his single-seater debut. He found the transition back from single-seaters hard.
"I find it tougher adjusting back to KZ from Formula Renault as the karting is very intense on the grippy tracks. It shouldn't take long to adjust back to the Renault, I'm more focussed on learning the circuit quickly as we have only two practice sessions before qualifying. Fortunately I have the support of a very professional team," he said.
British driver Lando Norris (who won New Zealand's premier open-wheel championship, the Toyota Racing Series in 2016) currently leads the championship and the grid will comprise many of the same racers Armstrong met at Nurburgring.
After this race weekend, UK-based Armstrong will begin a comprehensive winter testing program before returning to New Zealand in December.
