My question is regarding the use of an ADS-B out equipped aircraft while flying formation in a position other than lead.
During the pre-mission brief those pilots participating in formation flights in positions other than lead are typically directed to "Choke the Parrot" or otherwise put your transponder in standby mode.[/U] The lead squawks.
For those in the flight with ABS-B out, the direction to Choke the Parrot appears to conflict with regulations outlined in:
Title 14: Aeronautics and Space
PART 91?GENERAL OPERATING AND FLIGHT RULES
Subpart C?Equipment, Instrument, and Certificate Requirements
Specifically,
CFR 91.225 (F) states, "Each person operating an aircraft equipped with ADS-B Out must operate this equipment in the transmit mode at all times."
CFR 91.225 provides the following exceptions:
"(g) Requests for ATC authorized deviations from the requirements of this section must be made to the ATC facility having jurisdiction over the concerned airspace within the time periods specified as follows:"
"(1) For operation of an aircraft with an inoperative ADS-B Out, to the airport of ultimate destination, including any intermediate stops, or to proceed to a place where suitable repairs can be made or both, the request may be made at any time."
"(2) For operation of an aircraft that is not equipped with ADS-B Out, the request must be made at least 1 hour before the proposed operation."
Lets assume these formation flights are occurring mostly in Class E adjacent to Class C and Class D.
Can someone explain why only the lead squawks/transmits and the rest standby.
What is your experience during formation flights, are participants in the flight, who are equipped with ADS-B out transponders setting them to: standby, off, on (transmit) or something else?
Your direction and experience is appreciated.
Any ATC folks out there? Please chime in.
