Collision Avoidance and ATC
In the US, ATC is only responsible for providing separation services
between IFR aircraft, not IFR from VFR. They will call out VFR aircraft time permitting. A glider pilot with a transponder might have the false impression that someone is providing separation services for them. This could happen as work load and time permit for ATC. So to sum is up: 1) ATC is not required to inform a VFR or IFR pilot of other VFR traffic. 2) It is the responsibility of both VFR and IFR pilots to avoid VFR traffic. Even if ATC calls out your position while thermaling, an aircraft traveling 250 kts might only get a glimpse of you ever mile while you circle (assuming you are visible when perpendicular to their flight path twice in a turn). With TCAS, a glider pilot has better chance of detecting approaching aircraft both VFR and IFR that are squawking codes and see / avoid them first. |

Headline should read - "HAWKER PILOT AND CO-PILOT DID NOT LOOK OUT THE
FRONT WINDSHIELD OF THEIR AIRCRAFT AND RAN INTO A GLIDER" - they were probably doing pre-landing tasks. All biz jet pilots should be aware of what "plowing into a glider" can do to their program - heads outside gals and guys. Adhere to the "SEE" part of "See and be seen".

Woody is exactly right. Say Bubba, do you think the NTSB will ask about
the gliders oxygen equipment and its use? That could bring a whole 'nuther angle to this scenario? Just thinking again? snoop rhwoody wrote: Headline should read - "HAWKER PILOT AND CO-PILOT DID NOT LOOK OUT THE FRONT WINDSHIELD OF THEIR AIRCRAFT AND RAN INTO A GLIDER" - they were probably doing pre-landing tasks.

Mostly correct but---
Per AIM Ch 3, sect 2, #1 f 2 mandatory Safety Alert provided to ALL aircraft, conflict Mode C intruder alert (I presume this applies to transponder equipped aircraft only) and 3-2-3 Class B airspace---e. ATC clearance and separation provided to VFR aircraft and 3-2-4 Class C airspace ----e aircraft separation provided to VFR aircraft. So---if a plane is transponder equipped ATC is required to give a traffic alert if the controller detects an unsafe proximity. The warning would be given on the "local" ARTCC frequency, I guess. -- Hartley Falbaum "Bubba" wrote in message om...

Aircraft with TCAS are providing separation services for them, as are most of the aircraft using flight following and those with TPAS units. I don't know any glider pilots that think ALL other aircraft are being separated from them, because they realize a lot of the "Cessna" drivers aren't in contact with ATC, and know for sure the other gliders aren't. -- Change "netto" to "net" to email me directly Eric Greenwell - Washington State, USA www.motorglider.org - Download "A Guide to Self-launching Sailplane Operation" |
