gCAP Limited
Instrument Flight Specialists




About the Company

gCAP was formed in 2003 in specific response to an obvious lack of instrument approach plates designed with helicopter pilots in mind although, as a by-product, Cat A aeroplanes are also catered for. Instrument flight is often demanding at the most inconvenient of times, such as when your autopilot has dropped out and the weather's at minima, which is the very last time that you want to look down at your plate and realise that it's been written with Cat C/D aircraft in mind and needs interpretation for light aircraft.

Instead gCAP offers you a real alternative, which we believe is the clearest and most user-friendly on the market, designed specifically with Cat A aircraft in mind. We don't replicate VFR data so you'll need to carry a VFR guide such as those produced by Pooley's or Jeppesen. In addition, no non-essential information is shown, leaving an uncluttered diagram which is easy to follow even in a high-workload cockpit.

Our database covers almost all of the UK, plus selected airfields in continental Europe. You can see the full list by registering; this does not commit you to buying anything.

gCAP welcomes feedback because we are continually trying to improve the product. Please send an email to nick@gcap.eu. If you don't like the plates, please tell us. If you do, please tell your friends.

Differences from ICAO

ICAO Annex 4 states the standards required of, amongst other things, Instrument Approach Plates. The specification has been written with National Authorities in mind so that all ICAO countries produce AIPs which are essentially similar. In order to simplify the plates for gCAP it has been necessary to make some changes from the ICAO standard. This is acceptable practice, in fact neither Aerad, Jeppeson nor the AIP itself conform completely to the ICAO standards. The differences are as follows:

  • The 10d circle is not shown;
  • The scale of the chart is not shown;
  • Since all plates are Cat A, this is not shown in the airfield identifier (although there is a reminder along the left edge;
  • Topography and relief are not shown;
  • Magnetic variation is not shown;
  • Aerodromes other than the destination are not shown;
  • The aerodrome elevation is shown only when threshold elevation is not relevant;
  • Significant obstacles are not normally shown;
  • Prohibited, restricted and danger areas are not shown;
  • Bearings, tracks and radials are not normally shown on the vertical profile;
  • Timing to the MAPt is not shown unless the the position of the MAPt depends on it;
  • Recommended rate of descent information is not normally shown;
  • The height of ILS datums (ie the height of the transmitters) is not shown;
  • Aeronautical information (eg exact locations of beacons) is not shown.
