PTT switch

Stewart,

Most flight instructors and ATC Specialists actually suggest that one think for at least a heartbeat PRIOR to punching that PTT to respond.....time enough to put one's hand on the throttle, methinks.... :lol:

MTV

I had a choice of where to put mine. That was the basis of the question by and my response to Eric.

Mike and Tim,
That is correct on the key line, it is just grounding the circuit. I believe you wire them in PARALLEL, then you can ground that key line from any point with out pushing a series of buttons. But, my electronics is limited with lots of trial and error. Thanks for the responses.

yup, you are correct.. you could have 10 different ptt buttons wired in parallel controlling one mic jac.... not sure why you would though......

I gave you a reason for two. Modern airliners generally have at least two.

O.K. fellers, here it is. Co Pilot is on the tunnel, nothing on the rear stick to hamper stick removal. Pilot is on tunnel and stick. Can push switch no matter what hand, when ever, doing what ever it is we do in an airplane. The switch on the stick can be changed out in about 3 minutes with no under floor access.

JayH - Great looking stick grip/PTT, where did you get that? I've looked everywhere, and have yet to find that one?!?!

following this thread

I have flown every config. talked about in this thread and still like it on the front of the stick better that anywhere else. I like and agree with Mike's comment about not dropping the airplane BUT when flying with other airplanes all less that 100' and all looking or chasing the same object on the ground it becomes VERY important to state your positions and intentions.

It is a bit of a pain installing the button there but doable. I drill a hole at about 11:00 oclock and 1-2" below the bottom of the knob. Then I fish a small flexable with through the hole and out the bottom of the stick and wrap this end around the button on top of the switch. Feed the electrical wires while gently pulling on the solid wire until you have the button at the hole then use a pick to through the hole to kind of turn it while pulling it through the hole and installing the washer and nut.

In this position no matter which hand your flying with you have the PTT in easy reach, It will not get kicked and is completely out of the way. I use a couple of good connectors at the floor so If I have to I can completly remove the front stick but if all I need to do is remove the front seat there is enough wire to lift the stick off the stub and slide the seat over.

I only use this on the front stick If your instructing or whatever and need a back PTT put it by the throttle but they tend to get broke there by excited gunners getting the gun out the left side.

Like several others, I attached mine with velcro loop on stick low enough that i dont inadvertantly push it,but can easliy reach with pinky. Just seems natural location for me from helicopter days. I run wires under seat use velcro and wire ties to keep them away from controls/flap handle.

My L-21A has them in both places, front and rear. Tunnel buttons are surrounded by a shield. Bell 47 pistol grips with the trigger wired to transmit. The top button is wired to activate the intercom if I have the door open and the squelch turned way down to kill the wind noise from the back seat mike.

When I built my cub, I installer ptt on throttle cover in front of throttle, took a bit getting used to it but second nature in a short time. It is handy beeping able to remove sticks without messing with wires. My wiring doesn't have to move and should be trouble free just about forever. Now if I was flying cub IFR stick location would be best but, in this aircraft, I try to minimize transmissions other than in the pattern where my hand is always on the throttle except for flap deployment. My rear throttle is removable with field approval as having it in place creates too much excitement for me when the gunner in back has his shotgun in the way when it's time to add power upon completion of a pass.

Ray

agree with dave(agpilot),positioned mine after seeing daves on my exp. build,like he says,don't matter which hand,and feels very natural.also keeps my tumb off the top of the stick,with a 1'' more of panel and not wanting to cut the stick,(less levarage),pain will ensue with nose down movements!!!

Another thread resurrection.

New plane, new decision. I bought an itty bitty PTT from Cubcrafters that's small enough to drill a hole into the side of the stick a few inches down and still work this switch into that hole. Ya... no. I'm staying with the velcro PTT on the stick and will do what I always do, pull it up when I need to talk and push it down out of the way when I don't. Sometimes simple really is the best solution. For me, anyway.

PTT

I like my PTT on the front side of the front stick about 2" or so below the knob, That way you can't kick it getting in or out and its easy to operate with your pinky or ring finger.

Yet another thread resurrection but it is certainly an ongoing topic

Been putting off this decision but have to decide in the coming weeks. On the throttle tunnel is good but the obvious place ergonomically seems to be on the stick but that is where it was. With normal stick hold ie 4 fingers at the front and thumb at the back, when lowering flap and holding stick forward until you trimmed, found it awkward to bring thumb up to top of stick to transmit and maintain forward pressure, you had to rotate hand to push with palm.

I like the Boeing way, looked like they sprayed them all over but their test pilots really did think about it as you actually used all 3 of them especially the one on the sidewall when you were the non-handling pilot during arrival and departure. You made selections with the "inside" arm and the arm nearest the sidewall was pretty redundant so Boeing put a PTT between the jack points located there which worked really well when you discovered it.

I reckon one on the throttle tunnel and one at the location Dave recommends on the stick but perhaps at 11 o'clock.

Just a note to thank everyone for so many great posts on every topic under the sun, I learn so much from you guys.

Kind regards

Stew

Even if your friends thinks it's funny, it only has to work for you.
