Correct seat height C172

[I-WEBA]

Hello everybody!

I’m doing my ATPL and I struggle to find a reference on the correct seat height of the C172. I read that incorrect seating is primary cause of landing inconsistencies/pitch misjudgment. I found many different opinion, while the most common is: the seating which makes you more comfortable.

Can anyone of you give me some references where I can find the correct seat height or give me some advices?
thanks

I honestly think that whatever is comfortable is fine, as long as you can see over the coaming and make sure you always set it the same. Just make use you can see over the nose OK.

RVF750 is correct, whatever is comfortable, there is no design eye position in such an aircraft, it long, long predates even the idea of cockpit visibility design standards.
Tootle pip!!

whatever is comfortable,
So true. And don't be conned by instructors who say always have the seat arm rests down (whatever aircraft type you happen to be flying). That is their personal opinion only. As per previous advice, it is whatever is comfortable for you.

As others have said, whatever is comfortable. At this stage, it's probably best to find something comfortable, and (more importantly) keep it consistent. When you've figured out how to fly the thing, then experiment with different heights.

As an example, in a 172, I have the seat all the way up. I can't land or do manoeuvres if I can't see where I'm going. In my current airplane (Airbus) I sit higher for takeoff, and lower for landings. My previous jet, I sat high all the time.

Until you find out what works for sure, comfort and consistency are key.

When you sit higher you tend to flare higher, as your eyes are at a higher level, in jet transports where seat and eye position are important I’ve found that the lowest seat position that gives me good sighting over the nose has consistently given me better landings

C172’s have all the mod cons these days! The ones I flew didn’t have adjustable height seats!

I regularly fly a C182 and I crank the seat up until my headset just touches the headliner and then wind it down a bit. That gives me the best view over the very high instrument panel.

In the context of your ATPL what they are referring to is eye reference height or design eye height as there are several different names for the same concept.
Manufacturers determine this based on instrument position amongst other things.
Transport category cockpits have a reference symbol that you use to adjust your seat.

In a light general aviation aircraft it’s a little more obvious as to what it needs to be and ‘official guidance’ is not required.
You just need to be able to see over the cowling sufficiently for take off and landing.

For me it is always about repeatability.
On the big jets there is a system of some sort to get the eye height right but not on the bug smashers.
Find a seat position that works for you and relate it to other cockpit features so that you can replicate it every time and it's all good.
For me the seat height in a C172 is related to my flight plan folder height and seat fore/aft to my arms length closed fist. Works for me.
