Airport: KVRB (Class D) · Tower: 126.3 · Callsign: Skyhawk Three Four Six Echo · Pattern work, runway 12R

You are in the pattern. The tower keys up. Your readback has to be right.

Teach first. Then key up.

Every lesson opens with a sixty-second briefing — what the controller will say, and why. A quick check proves it stuck. Then you key the mic and say it yourself, graded word by word.

Lesson 4 · Tower

Brief

“Cleared for the option” means the choice is yours — touch-and-go, low approach, stop-and-go, or full stop.

Quick check

Tower clears you for the option. May you full-stop?

Yes — pilot’s choice

“Cleared for the option, runway two-seven, One Two Three Alpha Bravo.”

Backed by the FAA books.

No forum folklore. Every grade cites its source — AIM Chapter 4 phraseology, AC 90-66 pattern calls, and JO 7110.65, the manual the controllers themselves fly by.

Stay motivated.

Streaks, XP, and earned badges turn practice into a daily habit. Finish a chapter, pass its checkride, and the rating is yours — all the way to a thousand logged calls.

Take it flying.

Phone, tablet, or desktop — nothing to install. Prop it beside your flight sim, run a frequency on the drive to the airport, and key up like you have made the call a hundred times.
