ALAS ignores 25k altitude limit

[Ivandrov]

See track.

GBU-24 set up for ALAS continuous, I pick a random spot in the water to designate and climb up above 25k altitude. Observe Laser Arm light extinguish, and TGP screen "SAFE" I offset in order to induce error so that if the laser doesn't fire the bomb doesn't hit my designation point. I pickle, immediatly observe that I have laser ranging due to Slant range changing to feet, and the bomb guides perfectly onto my designation despite the amount of offset I put into the drop. No other entities in the mission.

Doesn’t the aircraft use different methods of determining slant range if there is no laser?  Like map system, radar etc.

Or, did you see the laser indicating it was firing, you don’t mention that in your post just that the slant range updated.

The bomb guided towards the center of the TGP despite a considerable offset from centerline on release. So, yes, the laser was on.

 

Yes, there are multiple ways for the Mudhen to determine slant range. I've only seen the slant range units change to feet with laser ranging.
