Line-Up, Take-Off & Frequency Change

What this scenario covers

1. Exchange 1

   ATC: “Golf Alpha Bravo, line up and wait, runway two seven.”

   Read back the line-up clearance. The runway is a mandatory readback item.

   Model reply: “Line up and wait, runway two seven, Golf Alpha Bravo”

   💡 "Line up and wait" means enter the runway and hold — it is NOT a take-off clearance. Never say "take-off" here; read back the runway with your callsign.

2. Exchange 2

   ATC: “Golf Alpha Bravo, surface wind two five zero, eight knots, runway two seven, cleared for take-off.”

   Read back the take-off clearance. This is a mandatory, safety-critical readback.

   Model reply: “Cleared for take-off, runway two seven, Golf Alpha Bravo”

   💡 A take-off clearance MUST be read back in full, including the runway, so any confusion over which runway is caught before you roll. This is the single most safety-critical readback in aviation.

3. Exchange 3

   ATC: “Golf Alpha Bravo, airborne time three four, contact Gloucester Approach one two eight decimal five five.”

   Read back the frequency change. Frequency is a mandatory readback item.

   Model reply: “Contact Gloucester Approach one two eight decimal five five, Golf Alpha Bravo”

   💡 Read back a frequency change in full so the controller knows you have the correct frequency before you leave theirs. Then make your initial call on the new frequency.

4. Exchange 4

   You have changed frequency. Make your initial call to Gloucester Approach, passing your callsign and that you are climbing (passing altitude 1200 feet).

   Model reply: “Gloucester Approach, Golf Charlie Delta Alpha Bravo, passing altitude one thousand two hundred feet”

   💡 On a new frequency, make a fresh initial call: who you are calling, who you are, and your current level. "With you" is non-standard — state your passing level instead.
