Training aids I use with students. They run on a phone or tablet, install from the browser and work offline once they've loaded, so they're ready in an aircraft with no signal.
An ADF for NDB work in aircraft that don't have one. Tune a UK beacon on the three drums, listen to its Morse ident, and fly the needle from the phone's GPS and compass, with a rotatable card or an RMI.
Open Pocket ADF
Track radials from a phone. Choose a CDI in the style of the GI 106A, set with its knob, or an HSI that turns with the phone's compass or GPS track. TO/FROM flag, Morse ident, and practice stations you can drop where you are.
Open Pocket VOR
Slant range, groundspeed and time to station, worked out from GPS and the station's own elevation. If GPS height is out, set the altitude by hand. Flown against an aircraft's own DME, it read the same.
Open Pocket DME
The view over the cowling on final, for learning what too high, too low and on the glidepath look like. Long, medium and short runways, PAPI or APAPI, a side profile and a picture quiz.
Fly it yourself in the pitch-and-power mode, modelled on a Cessna 152 at maximum weight, with flap settings, wind and turbulence. Day, dusk and night.
Open Final Approach TrainerThese are for practice and teaching on the ground and in the air with an instructor. They aren't navigation equipment, so don't fly by them.
Games, a quiz scorecard, and tools for the shoot and the league.
A scorecard for playing along with a daily radio quiz of two ten-question rounds: ladder scoring, one Joker a round, and your history kept on the phone. Full history and the calendar are a one-off £2.89 unlock.
Open Top Ten TallyFly a herding drone round the pasture and get the flock into the pen. One sheep in every field is naughty and runs straight at you.
Open Bloomin' SheepA word game against a rising pile of letters. Consonants keep falling and vowels are rationed, so make words of three letters or more before the grid fills.
Open Vowel VoidFor shoots. The keeper marks each peg on a map of the drive, and the guns open a link to a card with their pegs, the drive notes and the rules of the day. Licensed to shoots from £15.99.
The Stratford upon Avon & District Airgun League in your pocket: fixtures, results, averages, the rules of shooting and club contacts.
Scan a QR code and see exactly where it leads before anything opens. It flags lookalike addresses, shortened links, bare IP addresses and other tricks.
Still being made. Some are being tried out by instructors at the school; one is still a drawing.
Practise radio calls on the ground before you fly. Nineteen scenarios around Oxford, Gloucester, Birmingham, Wellesbourne, Wolverhampton and the Shawbury MATZ, in CAP 413 phraseology, with push-to-talk voice recognition and marking that forgives a slip.
Lesson and progress records for student pilots, replacing the school's paper air exercise and progress sheets.
Turn a paper pilot's logbook into a spreadsheet page by page, keeping a picture of each page and carrying the totals forward.
A training version of the G5 flight instrument: attitude and HSI, knobs that work by touch, the power-up alignment, taxi checks, and an instructor panel for setting failures.
A GI 275 simulator built from the pilot's guide: CDI, altitude alerts, ILS glideslope, the HSI map and spoken minimums callouts.
Plan a diversion in the air. Mark the new track on a photo of your chart and get heading, groundspeed, time, ETA and fuel, with the wind triangle solved properly.
The ground-school navigation computer on a tablet, with the circular slide rule on one side and the wind side on the other.
Time sums for the cockpit: add a duration, find the time between two times, convert Zulu to local, and run a timer. Red night mode keeps your eyes adjusted.
A daily domino puzzle. Fill the gaps, push one domino and watch the whole run fall.
