If you're thinking of a rapid parachute disembarkation feature, for busy executives in a hurry, don't forget they'll need their luggage and laptops thrown out with them

They usually fly down a localiser beam, which is inclined at about 3 degrees up from the threshold, so you will have to get the old Napier tables out :-)

Some airports (for example 'City' airports such as London City), and those surrounded by high terrain, like for example Innsbruck, require a steeper approach, and the aircraft permitted to use them will be certified for that angle.

For an extreme example - Google 'Twin Otter Landing' and imagine what a first time arrival would feel like from the cabin, with only a side view....

It's dependant upon the location, season and time of day.

for example in Singapore in the daytime, it could be coming in at 50 degrees, In London in the summer it could be 33 degrees.
But in Helsinki, at the same time, it could be coming in at five degrees

At 5000m I make it about 262 m,,,around 700 - 750 feet. Pretty low.

Ah the old 'buy a surface to air rocket launcher and threaten to blow up planes unless the authorities pay you £50million' plan B.

Does it not depend on the airport air traffic controller on duty?
