Name: La Serre d'Aulon Altiport

Subject: RJTT runway threshold discrepancies (AIP vs OurAirports)

RJTT AIP data vs OurAirports values do not match numerically

From the RJTT AIP:

RWY 16L threshold

Lat: 35 deg 33' 57.23" N

Lon: 139 deg 47' 11.59" E

From OurAirports:

16L Base Threshold

Lat: 35 deg 33' 57.24" N (very close)

Lon: 139 deg 47' 13.21" E (~1.62 arcsec off, approx 40 m)

This longitude difference is too large to be explained by rounding.

Reciprocal runway (34R) also shows inconsistency

RJTT AIP gives:

RWY 34R threshold

Lat: 35 deg 32' 22.90" N

Lon: 139 deg 48' 18.49" E

OurAirports shows:

Reciprocal Threshold (DER)

Lat: 35 deg 32' 33" N (~10.1 arcsec, approx 310 m difference)

Lon: 139 deg 48' 10.78" E (~7.7 arcsec, approx 190 m difference)

These are not small deviations and suggest a systematic issue.

Overall assessment

RWY 16L:

Latitude matches closely

Longitude shows a significant offset (~40 m)

RWY 34R:

Both latitude and longitude show large positional differences (~200-300 m)

RY information is incorrect. Elevation is 150m and RYs are 25/07 grass 830m x 28m

Sorry elevations is 155ft

The game is letting me in same room again and again. Pleaae fix the bug.

Please fix the problem

If this airport ever existed, it is no longer used.

There are no signs of an airport now or using historical imagery. Also, what is the source of the US-4169 code?

Hello,

Big Flat is a private airport on private property. We do not accept any landings without pre authorization. Any questions you can email me. Random landings provide a liability we cannot accept. Thank you.

Wrong airport elevation, it must be change, from 513 ft to 516 ft, in accordance with AIP Perú
