As the pilot, you will likely want to be conservative.

Look at the US Navy Diving Manual, Air Diving, available in PDF for free
at http://www.vnh.org/DivingManual/DMTOC.html

Don't worry about it.

Really.

The Earth's atmosphere is approximaetly 348 miles deep & exerts a
pressure of about 15 psi at sea level.

http://www.nasa.gov/audience/forstudents/9-12/features/912_liftoff_atm.html

When diving to a depth of 33ft our body is exposed to two (2)
atmospheres of pressure, one (1) due to the weight of the atmosphere
plus one (1) due to the weight of the water.

The change in pressure at an altitude of 1500ft is roughly equivalent
to diving to a depth of 1/3 of an inch.

That insignificant of a pressure change wont cause you to get bent, if
you do get bent it would have happened even if you stayed on the
ground.

Michael, as with ascending during a dive, it's not how high you go (to an
extent) but how quickly you get there. My suspicion is your rate of elevation to
1500 feet is going to be faster than the recommended ascent rate.

Don't do it. Decompression works by gradually dissolving microbubbles of gas
from your supersaturated tissues into the bloodstream and out via exhalations.
Too fast, the bubbles form much bigger bubbles and you get a DCI hit.

here...http://www.speakeasy.org/~neilco/bart.gif

if you don't understand the implications of R Benner's response, then you
should not be diving at all.

i.e., Wait at least 12 hours after diving before flying - can you guarantee
that a sudden unexpected updraft won't push your Cessna up to six or eight
thousand feet?

and TSA is worried about some old white lady with knitting needles.

It's not very hard to explain. People who get treated for bends
suffer an onset of symptoms sometime within the first 48 hours
following the dives. In other words, you can surface, feel fine
for a day and then bend from a dive the day before.

Making assumptions about physiological states and etiology based
on row/column position on a plastic card would be a bad idea. It
locates your position in a finite state machine and conveys nothing
except the length of your next dive.

There is a lot more to DCS than uptake and elimination. Gas in
solution accounts for only a small percentage of the bodies total
capacity for inert gas. It is the component/bottleneck that we
model, but not the entire system. It is not necessarily the
controlling component. It is just a reflection.

Correct.  

Being an "A" diver means that you are "close enough" to "normal"
that your next nodecompression stop dive does NOT have to take
retained nitrogen into account.  However, for traveling to altitude
you have to be "more nomral". -- Not that any of us are "normal"! <grin>

If you expose yourself to a high enough pressure altitude, you can
get bent without ever diving.  Dive tables and computers are designed
to minimze risk for returning to normal surface air pressure at
sea level.  The don't take into account travel to altitude.
Thus the various 24/18/12 hour rules.

The Airmans Information Manual, while not a "regulation" , states in Section
8-1-2. Effects of Altitude,

"d. Decompression Sickness After Scuba Diving.
   1. A pilot or passenger who intends to fly after scuba diving should
allow the body sufficient time to rid itself of excess nitrogen absorbed
during diving. If not, decompression sickness due to evolved gas can occur
during exposure to low altitude and create a serious inflight emergency.

   2. The recommended waiting time before going to flight altitudes of up
to 8,000 feet is at least 12 hours after diving which has not required
controlled ascent (nondecompression stop diving), and at least 24 hours
after diving which has required controlled ascent (decompression stop
diving). The waiting time before going to flight altitudes above 8,000 feet
should be at least 24 hours after any SCUBA dive. These recommended
altitudes are actual flight altitudes above mean sea level (AMSL) and not
pressurized cabin altitudes. This takes into consideration the risk of
decompression of the aircraft during flight. "
