At what speed is a takeoff aborted?

The Significance of Speed in respect of the decision to reject a take off. Most aircraft manufacturers specify an airspeed - usually 80 knots or 100 knots - which defines the transition between the low speed and the high speed part of a takeoff roll and represents a change in the expected use of a stop call.

What is the 50/70 rule? It's a general rule for GA aircraft that states if you haven't reached 70% of your takeoff speed by the time you've reached 50% of the length of the runway, you should abort your takeoff.

Length. A runway of at least 1,800 m (5,900 ft) in length is usually adequate for aircraft weights below approximately 100,000 kg (220,000 lb). Larger aircraft including widebodies will usually require at least 2,400 m (7,900 ft) at sea level.

At sea level, 3,200 m (10,500 ft) can be considered an adequate length to land virtually any aircraft.

If it's severe turbulence then yes, and if there are very strong crosswinds during takeoff or landing then the pilot can feel nervous about it.

It can also be very frightening. If you've never flown on an airplane before, it can be a bit scary.

Not true. I flew with a pilot that had ejected three times. Weirdly, I was with him (in another A-7) on two of those occasions. All three ejections occurred at slow speeds.

Longest Runway in the UK London Heathrow 09L/27R at 12,799ft x 164ft (3,902m x 50m) is currently the longest active runway in the UK.

Runway numbers are determined by rounding the compass bearing of one runway end to the nearest 10 degrees and truncating the last digit, meaning runways are numbered from 1 to 36—as per the diagram below. The opposite end of the runway always differs by 180 degrees, so it's numbered 18 higher or lower.

As Atlas Obscura explains, the numbers that runways have aren't arbitrary. A runway always has a number between 1 and 36, and that number isn't just the runway's nickname, but also indicates how many degrees away that runway is from magnetic north, rounded to the tens.
