Step 5. Data Available before Landing

Other Info

1. About 45 minutes before reaching the runway, ATC asks you to reduce your speed, because bad weather is delaying landings of many aircraft ahead of you.  ATC also gives you vectors (i.e, gave you directions) to go around some bad weather.
2. About 35 minutes before arriving, ATC tells you to expect to receive your clearance to land in about half an hour.  You realize that flying a holding pattern for this amount of time will mean that there would be less of a safety margin of extra fuel onboard in case you need to divert to an alternate airport (Ottawa).
3. About 30 minutes before reaching the runway, ATC reports reduced visibility in thunderstorms and heavy rain, and rapidly changing weather conditions.  Other aircraft refuse to land on runway 23 because it is close to the bad weather, and because the instrument landing system (ILS) glideslope was knocked out by lightning.  Runway 24R is out of service because lightning knocked out the ILS.  ATC tells you to expect to use runway 24L at Toronto.
4. During the next 15 minutes, as you monitor your radio, you hear that some of the aircraft ahead of you decide not to land at Toronto because of the bad weather.  These aircraft request vectors to alternate airports.  However, other aircraft ahead of you are landing successfully at Toronto, although they are reporting a wet runway with poor braking action.
5. Eight minutes before reaching the runway, lightning strikes the Environment Canada weather station at the airport, causing it to go offline.  Hence, the Air Traffic Controllers in the control tower are unable to give you updated wind info just before you reach the runway.
6. Two minutes before you reach the runway, there are dozens of lightning strikes to the approach end of the runway - - the end you are aiming for.  Visiblity is very poor due to low clouds and heavy rain. 
7. You have spent so much time holding for your approach clearance, and flying around bad weather, that you are not sure if you have sufficient fuel remaining in your aircraft to fly from Toronto (if you cannot land there) to your alternate airport at Ottawa.
