"It's a bit like doing pushups with two arms.
"If I'm lucky, I'm able to get two push ups, but if I take one arm away, I'm lucky to get half [a push up].
"If you take away one engine [of a plane] you don't necessarily get half the power.''
Mr Lowe told Judge Phillips, when asked, the airline put no pressure on any pilot to fly if they were not comfortable.
"There's no pressure for any aircraft overnighting in Queenstown when it should be overnighting in Sydney?'', Judge Phillips asked.
"I sometimes think it's more of a perception. We certainly do not pressure anybody to leave,'' Mr Lowe replied.
"If they're not comfortable, then they should stay, whether that's Queenstown, Brisbane or Christchurch.
"We have a duty manager system in place _ a pilot rings a central number, hits a few buttons and that will be directed to a duty manager.
"We all have mobile phones, we're all available [if a pilot is unsure].
"If he [the pilot] doesn't want to go, he doesn't go.''
