TrainYourHold
Fly IFR holding patterns, radial intercepts, DME arcs and procedure turns in your browser, with a realistic HSI, VOR and NDB (QDM/QDR), wind, entries and timing. No install, no account, just open and fly.
This stays free, with no ads and no account. If it has helped you, you are very welcome to buy me a coffee.
Best experienced on a desktop screen. On your phone or tablet you get one big compass and fly it with your fingers, in portrait or landscape.
TrainYourHold is a free VOR and NDB simulator that explains each procedure and then lets you fly it. Every ICAO holding entry, every reversal, the arcs and the intercepts, on a working HSI with wind and timing. Written guides for each one, a holding entry calculator for the quick answer, and unlimited random exercises to practice on. It runs entirely in your browser.
Heading bug, course pointer, CDI and bearing pointer, flown like a cockpit instrument.
Hold at a VOR with CDI and TO/FROM, or fly the harder ADF way with proper QDM and QDR wording.
Direct, offset and parallel, with the 70°/110° entry sectors drawn on a moving map when you need them.
Join radials inbound and outbound using the 45 degree, 90/45 and homing methods from the built-in guide.
Join a DME arc from a radial, hold the distance around the station, and leave it at the lead radial to intercept the next one.
Wind up to 50 knots, ground track diamond, groundspeed, a built-in stopwatch and time acceleration up to 8x.
No download, no account, no personal data. Random solvable exercises with one click.
