I can't give you a verifiable answer, but my CFI said the ceiling for the
28-161 is around 12000 to 12500. I trained in two of these Warriors this
past summer and was unable to find it in the POH either. So I asked my CFI.
Hope this helps.

If you'll spend an hour running a Bootstrap analysis on your Warrior (takes
about an hour) you'll be able to compute the absolute ceiling (or the
service ceiling, for that matter) without any difficulty.

Hi folks,

I've been studying for my checkride lately and reading just about
everything I have on aviation. As I was reading an article in Flying,
it occurred to me that I can't remember what the maximum altitude is
for the P28A-161 that I fly.

I thought I remembered that it's around 13,000' to 13,500', but I
can't find it written anywhere. I've looked through the POH and
couldn't find it. I know that without oxygen that I can't take it
over 14,000', but that's a different question.

Can anyone help me with what the max altitude is and where I should be
able to find it?

Many Thanks!

Rob Batchelder

It depends on the temp, weight, your skill at adjusting the mixture and holding
a precise attitude and how fresh or tired the engine is and what prop you have
and probably a few more factors I can't think of right now. I ferried a
Warrior from TX to OR right after an overhaul and climbed it to 15700 to get
over some weather in the Rockies (yes I had O2. I have a canulla rig and
medical reg. that I rig to a 63c.f. scuba tank I have. BTW all my tanks are O2
clean.) But it was also early Feb. and very very cold.

The service ceiling for the Warrior is 13,000 feet. That figure is in
density altitude (as are most all service ceilings for A/C). Maximum or
absolute altitude is another figure which is dependent upon how physically
high density altitude will allow the aircraft to fly.

HL,

I'd buy that. With one in the a/c and maybe half fuel or so. I know that
12,000 is the ragged edge on a slightly above standard day at near gross
weight in one, from personal experience.

According to the book "The Piper Indians" by Bill Clarke, page 37 the
service ceiling for a PA-28-161 is 11,000 ft

I checked my POH for the PA-28-161 (Warrior II) and it states that the
service ceiling at STP is 12,000 feet. However, I have seen other books
which state 13,000 feet as the service ceiling. IMHO the POH rules, 12,000
feet is all she does without jet assist or tossing out the passengers,
their seats, and anything else you can unbolt.

Could you tell me where in the POH you found this? I've looked
through mine, and while I expect that it would be in there, I can't
seem to find it.

Also, I thought that all FAA-certified aircraft were approved for a
definite service ceiling. Is this correct? If so, this number must
be published somewhere that a pilot can access it?

Thanks,

Rob

Until you get into pressurized aircraft, where pressure differentials and
serious engineering are at work, an aircraft's service ceiling is generally
considered to be:

The altitude (at standard conditions) at which the climb rate of the airplane
(loaded at gross) drops below 100 fpm.

Actually it is on several pages in section 5, Performance. Refer to the
chart on page 5-19, figure 5-11, climb performance. The follow the Std.
Temperature line up till it stops (12,000 feet). That is the published
service ceiling for STP. As a general practice, climb performance charts
stop at the planes published service ceiling for STP.

To my knowledge the FAA does not certify light, unpressurized aircraft to
any definite service ceiling. The service ceiling provided by the
manufacturer is based upon their own testing and engineering estimates and
is provided in the aircraft's POH for the pilot to estimate the aircraft's
performance.
