Flight Sim Checklists keeps the cockpit flow in your hand while you fly on the sim. Pick your aircraft, work the checklist challenge-and-response style, and tap each line as it's called — no scrolling a PDF on a second monitor, no losing your place halfway down the approach. Built for desktop simmers who fly with a phone or tablet propped up next to the yoke. AIRCRAFT INCLUDED • Airbus A320 / A330 — 11 sections, Cockpit Preparation through Securing the Aircraft • Airbus A300 — 9 sections, Before Start through Securing Aircraft • Boeing 737 NG — 10 sections, Preflight through Secure 158 items in total, written in the ACTION → RESPONSE layout used on the flight deck, so what you read matches what you'd hear. RUN A CHECKLIST • Tap any line to check it off — it dims so your eye lands on what's left • Mark a whole section complete in one tap, or unmark it to run it again • Move between sections with buttons labelled with the actual next and previous section names • Haptic feedback on every check, with a distinct confirmation when a section completes SEE WHERE YOU ARE • A progress ring on each aircraft card shows how far through the flight you are • The section menu colour-codes every section: not started, in progress, or complete • Reopen an aircraft and it drops you straight back at the first section you haven't finished • Aircraft with a flight in progress sort to the top of the home screen • Reset a single section or the whole aircraft whenever you want a clean start • Progress clears itself after a day of inactivity, so the next flight never starts half-checked BUILT FOR iPHONE AND iPAD • iPad runs a two-column layout — section list on the left, live checklist on the right • iPhone keeps the checklist full-screen with the section list one tap away • Portrait and landscape, so it works flat on the desk or clipped to a stand • Dark mode, Dynamic Type, and full VoiceOver labelling on every item NO STRINGS • Works completely offline — every checklist ships inside the app • No account, no sign-in, no subscription • No ads, no analytics, no tracking, nothing collected about you For flight simulation and training-familiarisation use only. Not for use in real-world aviation. Not affiliated with, endorsed by, or sponsored by Airbus, Boeing, Microsoft, or any aircraft manufacturer or simulator publisher. Always fly the real aircraft by its official, current documentation.

About

Tower 27

Features
Read full description

One aircraft on approach. Another waiting to depart. You coordinate what happens next. Take the tower at New York JFK in Tower 27. Watch arriving and departing aircraft, select a flight and issue its next instruction. From the runway to the apron, each movement is part of the airport's wider flow. FROM ARRIVAL TO DEPARTURE Manage arriving traffic and guide aircraft through their next steps on the ground. Coordinate pushback, taxi, line-up and takeoff. Follow traffic as it moves around the airport and keep track of more than one aircraft at a time. PUT EACH INSTRUCTION IN CONTEXT Select an aircraft, check its state and follow the on-screen radio exchanges. Decide when it is ready for its next step. Tower 27 connects the view from the tower with the individual movements on the apron and runway. CHANGE YOUR POINT OF VIEW Watch the airport from the tower or follow an aircraft up close. Switch views to inspect activity on the ground and see how aircraft, taxi routes and apron operations fit together. BUILD YOUR LOCAL CAREER Learn the flow through training shifts and continue your local career. Airport equipment upgrades add another dimension to your progress, giving each new shift a place in your own tower career. DESIGNED FOR IPHONE Play in landscape with an English-language interface. Radio exchanges appear as text; the current version does not include spoken radio audio. For people who enjoy watching airports and want to coordinate the action themselves. Tower 27 is an entertainment simulation, not an aviation training or operational tool.
