Met Office GA site: The official source in the UK for Synoptic charts, F214, F215, METAR’s, TAF’s and Rainfall Radar. You can also subscribe to email weather warnings for two local airfields. The GA Met Service is funded by the CAA out of fees levied on commercial aircraft. You will need a free account to use this site, which you can request here. |

Autorouter’s GRAMET tool: displays a profile of the weather (wind, cloud, temperature etc) along a chosen flight route. Primarily developed for IFR pilots but also useful for longer VFR flights. |
| BBC Weather: gives an outlook for 14 days ahead. |
Other planning
| Many of us use SkyDemon or a similar app for NOTAM’s. NATS is the official source of UK NOTAM’s which can be reached here. You can also register on the same page for a free account if you don’t have one. | |
| NATS class D airspace pre-notification portal. By giving NATS 1 hour notice, this portal improves your chance of getting a class D transit by helping ATC to plan for your expected transit time. | |
| Skydemon home page and page to login to your online Skydemon account |
W&B
This website has W&B calculators for many different aircraft. Always ensure you are using the data provided for your specific aircraft from its W&B data sheet.
Take off and landing performance
CAA recommended take-off and landing performance factors can be found here
GASCo App I haven’t found a website which computes these data, but GASCo offer an app for smart phones which does this. Also available for the iPhone
PLOG’s and planners
All these best-practice PLOG’s, together with a short user guide, can be found on the Downloads area
International flights
Many of us file flight plans directly from SkyDemon or a similar app. This link gives access to the NATS AFPEX online system.
GAR form
A GAR form is required for all flights inbound from EU countries. It is also required for flights both to and from the Republic of Ireland, Northern Ireland, Channel Islands and Isle of Man and all non-EU countries. The form can be input online here. You need to buy credits as there is a fee £2 to £3 per submission, depending on how many credits are purchased. The fee is refined if the flight is cancelled.
European AIP’s
Here is Eurocontrol’s index of AIP’s. For some of these AIP’s you may need an account (free); others are accessible without an account.
Fuel drawback
Fuel drawback form. Fuel drawback is the term for the HMRC scheme which allows a pilot to re-claim tax paid on fuel which is exported from the UK on a foreign trip (even if some of that fuel subsequently is re-imported). You also need a Government Gateway account which you may have already if you file tax returns online. Otherwise, apply online here.
Android app’s
There are many Android phone app’s for pilots. Many are free, some cost a few dollars. Some are very reliable and useful; others regrettably have limited value and may not always be trustworthy. Without offering any express warranty, the app’s below are ones which I use regularly.

Rainy Days One of several apps which display rainfall radar on a GoogleMap background. |

Weather & Radar UK, developed by the German company Wetteronline gmbh.- is another good app. It shows cloud as well as precipitation and distinguishes (somehow) between rain and snow. |

Aviation Pocket-knife / Aviation Weather with Decoder My favourite for METARs and TAF’s. Presented in in native format or plain English, plus many other useful functions (cross-wind calculator, Snowtam decoder, GoogleMaps view of airfields, NOTAM’s for airfields). |

UK Rules & Regulations
Neither the UK Air Navigation Order nor SERA (Standard European Rules of the Air) are light reading. The CAA’s Skyway Code is a useful reference document.
