Hi all,

I believe the Tornado IDS has some kind of nav system for low level flight that shows in the HUD the fligh course and level depending on ground elevations, excuse me for my english, I believe it is a kind of system that warns the pilot about the correct safe trayectory.

I wonder is the hog has something similar, or if it is all from the pilot by visual skills, maps, etc etc

Thanks in advance,sorry if I am asking something very stupid that should know.

Farris, the A-10 has an INS (Internal Navigation System) like all modern fighters, in fact it just got an update to the system which uses GPS for better navigation. There are symbols in the HUD to help you steer your aircraft to different waypoints.

The A-10 also has Radar altimeters which gives you your height above ground, included in that system is G-CAS or, Ground Collision Avoidance System, Bitchin’ Betty will tell you, “pull-up, pull-up”!

Hi again,

Thanks dice four your response, but I believe that the difference with the system Tornado IDS has is that in this one, the computer drives you trough the HUD to a low-level flight, I mean, it analysis the terrain and drives you, it means, it anticipates so the pilot responds so to keep certain contant heigh.
I remember to read some years ago that if a Tornado pilot flies trough a valley, the computer tells the pilot when to pull the stick so the plane will fly over the obstacle at a certain heigh. But this info seems comes trough the HUD, not by a bitchin´ betty. Nevertheless I am not sure if this is correct or not, that is why I wondered if the A-10 has a similar system or not taking into consideration that both are specific low level flying airplanes.

Again, thanks for your answer.

It´s me again.
I have found it, the system is called DTS (Digital Terrain System).

Provides the A/OA-10 with a digital terrain system through the use of a Mega Data Transfer Cartridge/Processor (MDTC/P). The digital terrain data is loaded onto the MDTC and terrain elevation is continually processed within 10 km of aircraft position. DTS will provide a predictive Ground Collision Avoidance System (GCAS), terrain referenced navigation (TRN), database terrain cueing (DBTC), passive ranging (PR), and obstacle warning/cueing (OWC).
DTS will significantly improve current GCAS by providing a predictive system to protect pilots from controlled flight into terrain (CFIT), the primary cause of A/OA-10 class A mishaps. DTS will significantly improve weapons accuracy through PR and target elevation data due to A/OA-10’s lack of any other means to determine the bombing triangle slant range to the target. Provides increased coordinate accuracy by eliminating elevation errors. Current system (Radar Altimeter) treats the earth as a flat plane; this modification provides a new capability to the A/OA-10 significantly improving system effectiveness

Date 1994, so I guess never took place, sure most Hog pilots would like to have it, it´s been hard to find this info.

The FB-111 has something, it actually flies the airplane at the lowest possible altitude, pulls up over dangerous terrain, then drops down again, all auto-pilot, so the pilot doesn't have the stress of low-level flying.

had something...the 111 has been out of the (U.S.) inventory for a while now...

Meant that, "s" and "d" keys are close together, and sometimes I type really fast and hit the wrong key by mistake. Are there any other deep-penetration planes that also have this feature, such as the B-1B or the F-15E?

"Retreat, hell! We just got here!"-Captain Lloyd Williams, 2nd Marine Division, Belleau Wood, France, WWI

Both have that feature. I'm sure the F-117 does too.

So does the block 40 lawndarts if they are carrying the navigation pod from the LANTRIN system.

"face it....perhaps your only purpose in life is to serve as a warning to others!"

Yeah, but the F-117 and the B-2 aren't made for low-alt flying. And I didn't know F-16's were ever under 10,000 if they weren't taking off, landing, or crashing.

Yes the lawndarts can and do travel under 10,000ft. They practice TFR as a normal part of their training.

"face it....perhaps your only purpose in life is to serve as a warning to others!"

B-1B is specificly optimized for low altitude penetration. It just doesn't operate in that role anymore. Really, only the A-10 and the gunships do.

"Trample the wounded...hurdle the dead"

somewhere in the middle of the program, the B-2 had significant upgrades to the wing, to allow for low altitude "nap of the earth" type flight. The F-117 only has FLIR and DLIR, so not sure if it has a "coupled" automated system for low level flight.
