Can You Read This Heathrow ILS 27L Approach Plate?
Heathrow's ILS RWY 27L is the most-flown approach in European flight simulation. UK plates use a different format to FAA plates — this quiz tests whether you can read both. Expect questions on the localiser and glideslope frequencies, decision altitude, missed approach routing, and the transition altitude that catches out pilots unfamiliar with UK airspace.
