runway slope requirements

good day

are there any minimum requirements about runways and minimum clear area for approach and go-around .
there is an situation where owner of private jet wants to build an airfield for his plane but problem is that the region is mountainous and I just wondering if he build small airfield with concrete runway his operations on it will be legal.
Let's say that approach path will be 5 degrees and his plane will met this requirement and go-around will be with gradient 6 and plane also met this requirement.
Maybe there are some maximum limits about slope over which airfield can't be registered ?

thank you

It appears that your geographical location would use ICAO standards.

Obstacle clearance and other factor would depend on what operational level of flight is to be used. Doubt if one should try an IFR approval for the procedures.
It is likely this will be a visual approach, so that will dictate the obstacle clearance areas, and minimum requirements.

In many mountainous regions, a spiral down approach is required to meet aircraft performance levels. As it is mountainous, (and private) one should probably look at a missed approach procedure as part of the design...

As this appears to be a private airstrip, there may also be exemptions that can be applied for.

Nor really necessary to use a concrete runway for a small jet...unless there are adverse soil conditions..

Good luck

thanks for that info ,

now I have more details can you help me with calculations

Planned rwy elevation 1000 ft , rwy 17
there is mountain on approach distance from rwy threshold 2NM top 1913 fr
if I am correct minimum slope for approach is 5 degrees ?

chr,

with all due respect, there is quite a bit of details regarding the designs and the viability of this approach/missed approach procedure.

EDIT: perhaps if you look at some of the FAA design guides, such as 8260.58, most a fairly easy to follow, and get an idea of all of the design parameters, glidepath angles, and obstacle clearance surfaces. They have the turn parameters, roll out points and other guidelines for the approach waypoints, and missed approach altitudes.

The ICAO 8816/9992 aren't as much fun, but would be more applicable to your geographical area.

FAA 8260.58

runway slope requirements

Hi chr. Give us the exact and precise lat/long of the runway midpoint and I'll take a look.
