TOPIC: Better seat belts

Better seat belts 2 months 4 weeks ago #1233

Rod,

Sorry for the delay in replying. I just checked my plane last night and I do not have shoulder harnesses in the back seat, just lap belts.

Thanks Joe. Do you have 4 point seatbelts in the back? I bought the BAS for the front but would like a better price for rear belts.

I have a 4-point system in my 1965 172F. It was installed before I purchased the aircraft. The shoulder harnesses attach to the ceiling and it appears as though it uses the existing lap belts to fasten to. The shoulder belt fasteners have slots that fit over the lap belt mechanism which fits into the latch. They seem to work really well and i like the extra margin of safety they provide.

Thanks Jose. You've given me a lot to consider.

Rod,
I am sure you know that the 15 extra HP will give you shorter takeoffs and higher rate of climb but not faster cruise speed.
To increase cruise speed you need to reduce drag a lot, so if you want a faster 172, buy a Cutlass. Speed kits are overrated. You need to spend thousands of dollars to gain a couple of irrelevant knots. Do the numbers, a 240 NM flight @ 120 KTAS takes 2 hours. The same flight @ 122 KTAS will save you 2 minutes. It just doesn’t make sense.

This said, the truth is that owning a Cessna doesn’t make sense. We do it because it’s a pleasure, so we don’t need to justify anything. I know a C170 with $250K in “improvements” which owner wouldn’t be happier with a Citation.

Reducing the low end speed is a lot more productive. Adding a Sportsman leading edge and VG makes a LOT of difference in STOL operations. Always will be a penalty in cruise speed but not a lot.

Adding just VG to your airplane will mostly give you more rudder, elevator and ailerons authority at low speed, what is great in crosswind landings. Again, it will be a small penalty in cruise speed.

I am not aware of any single modification for the 172 that will let you go both slower and faster, as you want. For the 182, a canard wing improves both, but a little in the fast end and a lot in the slow end.

BTW, I have a 182Q. I don’t know if a 172XP has room for a center console. You can use two MH electronic devices with a tank if you want to spend $2K+ extra to use standard cannulas instead of moustaches. I only have oxygen for the front seats. I don’t see the need to have oxygen in the back. If I have passengers, I don’t fly high for extended periods.

Thanks again Jose. That also looks like just the kind of oxygen kit I am looking for. Do you have a 172? Mine is a 1978 model. I'm wondering if the SAIR organizer will fit between the front seats. I see the pulse demand system is for 2 occupants. Could I add another unit for a third passenger or do you do something else when you have more passengers?

And since you are giving me such great advice, I have a few more questions. Of course I would like my plane to go both slower and faster. I'm getting the upgrade to 210 HP right now. The wheel skirts are old and broken. I've been wondering if the knots-to-u skirts would actually add any real speed and if they are easily removable, since I live in a northern climate and can't have them on in the winter. I'm also wondering if wing vortex generators are a good choice. If they slowed me at the top end, I'm not sure I would like that. Do you know anything about either one of those systems?
