Mode S code

Ok, I'll be the slow one today. .215(c) says "airspace as specified in paragraph (b)." Paragraph (b) says A, B, C, above 10,000 ft, and within 10nm of any airport listed in Appendix D, section 2.

How does that make it illegal to fly with the transponder turned off in class E?


99.13

(a) Aircraft transponder-on operation. Each person operating an aircraft into or out of the United States into, within, or across an ADIZ designated in subpart B of this part, if that aircraft is equipped with an operable radar beacon transponder, shall operate the transponder, including altitude encoding equipment if installed, and shall reply on the appropriate code or as assigned by ATC.

edit: after reading that pertains to ADIZ only. hmm


ah theres the right one. 91.215(c)

(c) Transponder-on operation. While in the airspace as specified in paragraph (b) of this section or in all controlled airspace, each person operating an aircraft equipped with an operable ATC transponder maintained in accordance with Sec. 91.413 of this part shall operate the transponder, including Mode C equipment if installed, and shall reply on the appropriate code or as assigned by ATC.

Ok, I missed the "all controlled airspace" line. My bad.

Means they wasted a lot of text because almost all of section (b) is describing controlled airspace.
 
Which is also a violation of the regs...unless you're an A&P and you're going to re-do the W&B


Part43 Appendix A

(31) Removing and replacing self-contained, front instrument panel-mounted navigation and communication devices that employ tray-mounted connectors that connect the unit when the unit is installed into the instrument panel, (excluding automatic flight control systems, transponders, and microwave frequency distance measuring equipment (DME)). The approved unit must be designed to be readily and repeatedly removed and replaced, and pertinent instructions must be provided. Prior to the unit's intended use, and operational check must be performed in accordance with the applicable sections of part 91 of this chapter.

Curious as to why there is an exception to transponders?

There's no context to what you posted, and I'm too lazy to google it.

Is it saying you CAN or CAN'T remove a transponder head unit without an A&P license?

Cannot. That is the section that defines "preventive maintenance" that may be done by a pilot with a private or higher certificate.

Opps, sorry. Thats from what you are allowed to do on an airplane if you are a rated PPL. But even still, he would have to be the registered owner. So no, you can not remove the transponder.
 
I'm sorry, I just can't believe a state downloads FAA tapes to run tail numbers so they can tax airplanes that fly over a state.
Sounds like something people make up around an FBO or flight instructors arguing over regs they've heard about.

Yeah, it's hard to believe anyone is trying to tax flying over their state. I know there are plenty of examples of trying to tax planes that have landed in a state.

Not about flying over a state, but rather landing and having the aircraft within the state within a certain time frame after its purchase.

Aircraft owners, to the best of my knowledge, can do direct swaps of radios. My guess is that since transponders and DME (in a non-radar environment) are both used in separation of aircraft, the FAA doesn't want the average Joe pilot messing around with them.

Automatic display of tail numbers on en route scopes isn't possible...yet. ERAM is *supposed* to provide such functionality, but I'm not 100% certain if it will work with Mode S or will only work with ADS-B equipment.
 
even if the guy is trying to avoid a state for fiscal reasons, how much is he burning in gas and cost in mx to circumnavigate the state? might have him take a look at that.

Either way I think the fella is a little stupid.

Completely depends on why he's avoiding the state.
 
I seriously doubt and to the best of my knowledge it don't think mode s transmits the n # when on a 1200 code. I say this because the powers that be spend countless hours chasing down and trying to identify restricted airspace violators(I.E. DC SFRA) I am talking everything from state of the art Cirrus' to miltary Blackhawks to beat up old C-150's(meaning equipment is not a factor in ID or non-ID) have violated the SFRA and continued flying and the same difficulty existed in tracking down the aircraft in all of them. If they were ever going to use it that would be the time but alas no such thing is happening.

While a huge pain in the ass, and the reality is that he may simply avoid said state for 12 months to remain fully legal as opposed to trying to playing the cat and mouse game, I think a lot of us would consider avoiding almost $30k of sales tax not stupid.

And I'm guessing thats the state your supposed to be based out of?

I dont know exactly what state hes talking about, but im sure we all know of some of the north eastern states that like to tax the plane owning "fatcats" to supplement their entitlement programs.

Never mind the fact that the state doesnt actually own the airspace above it.

He owns property there, and would like to be able to fly in and visit, but if he does so within the first 12 months he owns the thing, and the state finds out about it, he gets hit with state sales tax.

As much as it sucks, he is probably just going to avoid said state and keep things fully legal.

I know you and I kinda talked about adding a second XPDR like a GTX327 and running that while over state lines.

Another thing you could do, is just put an INOP placard over the XPDR and say it doesn't work and turn it off while flying. Perfectly legit.

Ya.... like I said, just think he's going to be avoiding this state in particular until he can legally go into it.
