Why we built A4Flight

## The school and club we wanted to fly with.

We wanted modern aircraft, a place to meet and flying that fits real life. So we built it at Denton Enterprise Airport.

Learn with an instructor. Come back to flying. Or join as a certificated pilot and make the fleet part of your life. Different paths, the same love of aviation.

The airplanes bring us here. The people make it A4Flight.

### Modern aircraft

Cirrus SR20-G2s and a Jabiru J170. Aircraft you'll look forward to flying.

### Built around you

Your goals. Your calendar. No factory syllabus.

### A proper home base

A private office and lounge at Sheltair, with the aircraft right here at KDTO.

Our journey

## How we got here.

Snake-infested hangar. Old, crappy airplanes. Enough was enough. We built the school we wanted. From our first aircraft to the club we fly with today. The story is ours, and so are the photographs.

Our full story in pictures

Chapter 01

### Where it started

Round gauges. Well-worn rentals. A route plan propped against the windshield and a hangar the snakes got to first. We flew them anyway — then one morning we said enough.

Round gauges, app on the yoke

Over Texas lakes

Well-used trainers

The Cherokee days

Steam gauges, good times

Route planning, early style

Rentals and more rentals

Six-pack instruments

Hangar days

Chapter 02

### The first one with our name on it

Then we stopped renting and started owning. Stick and rudder, a Jabiru with our name on it, and the first time the airplane was actually ours.

Glass panels early on

Flying the glass

Chapter 03

### The Cirrus era

Glass panels. Autopilots. Real cross-country range. The Cirrus SR20s changed what an ordinary Tuesday could look like.

N94RS arrives

Doors open, sun out

Sunset on the ramp

Evening light

Chapter 04

### Cross-countries and glass

Once the glass was in, we started going further — down the coast, over the water, panels full of numbers and the engine watched every mile.

Chapter 05

### The people

The airplanes are the easy part to photograph. Ask members what they actually remember and it isn't the aircraft — it's the people standing next to them.

Sunshine and Cirrus

The team takes shape

Good days at the airport

The left seat never gets old

Golden hour

Chapter 06

### Today

Two Cirrus SR20s, a Jabiru J170, hangar space at Denton Enterprise, and a portal that runs the whole operation — booking, dispatch, billing, training. Some of us still plan on paper.

The whole club, online

Still planning on paper sometimes

Modern cockpit, modern tools

This is where the story gets good — the next chapters get written by members.

From our flights

## This is what we come here for.

Our aircraft. Our flying. A few moments from the ramp to the runway.

### Austin Allen

Certified Flight Instructor (CFI)

CFI, CFII | Commercial Pilot, Single-Engine Land

Meet Austin

Austin holds his CFI and CFI-I along with a Commercial Single-Engine Land certificate. Flying wasn't on his radar growing up — he spent the better part of eight years in the trades before making the jump to aviation and moving to Texas. He always watched the sky, tracking CAL FIRE aircraft in and out of their Sacramento base, and after a discovery flight in Auburn he knew he was in the wrong profession. With a wife willing to move 1,500 miles so he could chase the passion, he settled in Texas and now works to give every student an aviation experience that is fulfilling and rewarding.
