Como esse personagem é capaz de pilotar uma espaçonave em “The Force Awakens?”

No livro de cânone, Antes do Despertar , é discutido que Rey teve acesso a um simulador de vôo, no qual ela passou parte do seu tempo. Também é mencionado que ela era muito habilidosa em voar em naves espaciais no simulador.

TL; DR: por causa de uma confluência de várias razões

1. Ela voou muitos ofício / lixo antes (seus termos), desde o nascimento
2. Foi mais difícil voar Falcon do que o filme fez parecer à primeira vista. Ela cometeu muitos erros
3. Seu "voo fantasioso" foi um acidente OU voando por um Destróier Estelar intimamente familiar
4. Ela estudou Falcon (e outros navios) no ferro-velho antes
5. Ela tem a força

Visual Dictionary confirma # 1:

1. Ela é um piloto qualificado

   She has also become a skilled pilot (page 30)

A novelização de Alan Dean Foster aborda isso de várias maneiras:

1. Ela voou muitos "ofício" antes.

   Turning, Finn headed for the indicated area. “You ever fly this thing? Or anything like it?”
   As BB-8 looked on, she shouted back to him, “I’ve piloted all kinds of craft, but nobody’s flown this old crate in years!”

   e mais tarde, depois de agitar o segundo TIE:

   “That was some piloting!”
   “Thanks.” She shrugged. “I’ve been flying every kind of junk you can imagine almost since I could walk.”

2. Era mais difícil voar que parecia, antes que ela pegasse o jeito

   Fully powered up now, it soared into the bright blue sky of Jakku—but not efficiently. Shedding tarps as it rose, it spun and careened wildly, nearly crashing back to the ground. Wrestling with the unfamiliar controls, Rey managed to level off just in time to crash into and through the town’s entry archway: Niima Outpost’s sole example of architectural pride.

   e mais tarde

   Driving the ship surfaceward, she pulled up at the last possible moment and sent them screaming across the ground, clipping the crests of at least two dunes.

   e mais tarde

   Just a little farther, she told herself as she clung grimly to the controls. Just keep them off a little longer. She was heading for her favorite scavenging spot: the ships’ graveyard. Let them try to follow her in there! She banked hard, low enough to cut a crease in the sand.

   e

   Trailed by the surviving fighter, the ship slalomed through the colossal debris field. Sparks flew as she grazed towering metal walls and fallen station sections, but the hull of the borrowed craft held together. As he was banged around in the gunner’s seat, Finn tried to keep track of their remaining pursuer while peering out at a trash-paved surface that frequently came entirely too near to where he happened to be sitting.

   Além disso, alguns dos " fantasia pilotando " você vê no início do filme (barrel roll quando o BB-8 foi virado de cabeça para baixo e precisou de cabos) foi um acidente

   Realizing it was impossible to reach the necessary instrumentation {{ she wanted shield controls on copilot's side }} while seated in full pilot’s position, Rey momentarily let go of the controls. She’d have to do this manually, she knew. Put any ship on autopilot and the vectoring would immediately be sensed by a pursuer, who could then lock on and blow you out of the sky. In contrast, there was just enough wild wobble in their flight path as she leaned to her right to confuse any electronic predictors. Her stretching, however, caused the ship to cant sharply as she tried to activate the shield instrumentation on the copilot’s side while maintaining some semblance of flight control.
   “Beebee-Ate, hold on!”
   Her warning came too late for the droid. Beeping madly, he rolled ceilingward as the ship spun.

3. A parte realmente perigosa do vôo (dentro do casco do Destróier Estelar), ela estava voando dentro de uma estrutura que ela conhecia em seu coração, intimamente, de explorações passadas (ela escolheu de propósito)

   Even a former crewmember would not have been as familiar with the corridors she chose. But she had not merely familiarized herself with them from a diagram: She knew them intimately, having inspected them individually and on foot or with climbing gear.

4. Mais tarde, quando eles conhecem Han, ela explica a ele que conhece bem este navio desde que o estudou enquanto estava no ferro-velho de Plutt

   “Hey! Some moof-milker installed a compressor on the ignition line!”
   “Unkar Plutt did.” Rey saw Finn shoot her a look and she glanced away, abashed. “I’d spent some time poking around all the ships parked at the outpost. Mostly at night. It was a way to learn some things. I was careful, and nobody much cared anyway, since I never took anything or tried anything.” She brightened. “Made it a lot easier when we filched this one. Though it wasn’t my first choice.”

5. Para completar, ela está posicionada como sendo strong na força.

   Os dois últimos Strong In the Force Jedi wanabees eram ambos - em grande parte devido às habilidades da Força, desenvolvidas instintivamente antes do treinamento Jedi - eram grandes pilotos: Luke Skywlalker e Anakin Skywalker. O primeiro dos quais explodiu uma Estrela da Morte quando pela primeira vez em um caça espacial; o segundo explodiu uma nave mãe da Federação de Comércio, quando pela primeira vez em um caça espacial E com 11 anos de idade.

Ela é

Anakin's grand-daughter. She has his innate skills with respect to machines. She is a good at taking things apart and piloting them, just like her grandfather.
