Open Tower Drill, go to the lesson list, and tap any locked lesson. On the upgrade screen, tap "Restore Purchases" at the bottom. Make sure you're signed into the same Apple ID you used for the original purchase.
You can use the guided lesson content and speech practice without an internet connection. You need a connection to purchase Tower Drill Pro and to download the optional on-device AI model.
Tower Drill supports iPhone and iPad running iOS 17 or later. The optional on-device AI model works best on newer iPhone and iPad models with enough free storage.
For best results, use Tower Drill in a quiet environment and speak clearly at a normal pace, just like you would on an actual radio. Make sure you've granted microphone permission in Settings > Tower Drill > Microphone.
Practice airports come from the FAA's public NASR database: real runways, tower and ground frequencies, and approach facilities for 576 US towered airports, refreshed with app updates. The data is for training only: always verify frequencies against current charts before actual flight operations.
Tower Drill includes US public-use airports with an operating control tower. Non-towered fields are practiced through the CTAF lessons instead. If your towered airport is missing, email us and we'll look into it for the next data update.
Commute Mode is completely hands-free: ATC issues an instruction, the microphone opens automatically, you answer out loud, and the controller responds. No buttons. Audio keeps running with the screen locked, so it works great with AirPods or CarPlay audio on the drive to the airport. Keep your eyes on the road; treat it like listening to a podcast that talks back.
After each readback, Tower Drill can replay the transmission you just made, alongside the ideal readback. The recording stays on your device and is overwritten by the next transmission; nothing is uploaded.
Yes. All exercises use phraseology from FAA JO 7110.65 (Air Traffic Control) and the Aeronautical Information Manual (AIM). Tower Drill is designed specifically for US PPL students training under FAA regulations.
Training mode shows you the expected response so you can read along. Coached mode gives key items to include when you're stuck. Solo mode is a realistic simulation with no assistance, just like the real radio.
Tower Drill currently focuses exclusively on US FAA phraseology and procedures. While many concepts overlap with ICAO standards, some terminology and procedures differ. We recommend it for US-based flight training.
