RADAR questions? - Page 2

RADAR energy is line of sight with limited OTH (over the horizon) capability. The ability to see over the horizon is directly linked to the power and band of the set. The lower the frequency, the farther OTH the set can see. The transponder makes a BIG return, so it's easier than a skin paint. Sitting on the ground, your skin paint is nothing more than clutter...like a tree or a house. Ignored by the operator or filtered out by the set if it's an advanced one.
Some sets also have speed gates....it'll ignore all returns slower than XX knots (set by the operator). I don't think ATC would do this often (helo's, ya know).

The ability for ATC to see your transponder on the ground depends on the type of RADAR, distance from the antenna, and the terrain between you and the antenna.

I never turn the transponder on ALT until I taxi onto the runway out of courtesy for ATC and anyone that has TCAS. It is really annoying flying into a busy airport with constant traffic alerts from the tcas and having to figure out which targets are on the ground and which are potential conflicts.

Chunk must be using his mad AW skills! Did you fly in bravos or foxtrots?

Dude! I'm no rotorhead...flew S-3's and P-3's. Preferred the Hoover, for obvious reasons...

Sorry about that. I'm used to the helo AW's since they are more prevelant than fixed wing guys. Oh that's right, they kicked you all out of the S-3 community and you had to migrate to the P-3 cummunity in droves. Yeah I'm sure it sucked to fly around and be the Texaco Man all day. I wanted to be an S-3 AW, but I didn't get my #1 choice and had to go to my #2, AMS A school. The S-3 will be gone in two years anyways. Free up hangar space for the new combined HS/HSL squadrons.
