Oct 7–9 · Weekly Flight Plan
Terrain-following corridor missions with reviewed TOP alternatives and field checks.
TOP review
KM29+136 PIV is the validated TOP. Other TOPs are recommended scout areas; confirm access, a level pad and actual launch elevation.
KM37+450 is one launch/home point with a western observer near KM36+930. KM36+400 on the Cahuacán tunnel remains a candidate for comparison.
Flight setup
Use 75 m real-time terrain following with the appropriate raw DTM. Survey coordinates use ITRF2008 / EPSG:6369.
Record the actual TOP chainage, TOP ASL and panorama at 50 m AGL with aircraft ASL. Separate mission/TOP records with ****.
Field note standard · TOP, ASL and panorama readings
Record actual KMxx+xxx TOP, TOP ASL, and the panorama at 50 m AGL above TOP with aircraft ASL. Use **** between mission/TOP records. Field order may change; no sequence numbers are assigned.

KM37+450 remains the reviewed primary launch with a western observer near KM36+930. The tunnel-top model shows masking through KM37+240 and has no surface rays from KM37+410 onward, so full-corridor coverage is not established. Confirm the tunnel pad and actual launch elevation before selecting it. Alternative 2 needs an observer adjustment near KM37+790–KM37+860.

For KM39+500–KM42+000, resolve visibility at KM41+890 and the descent at KM41+950–KM42+000 with an observer beyond the crest or local capture. For KM42+400–KM45+500, check KM42+400–KM42+460 locally. Both corridors now use real-time terrain following in FlightHub.
