Gear up takeoff

"Roy Smith" wrote

Bombers have an advantage over other types on these types of takeoffs.
When you feel the aircraft starting to settle, you can just hit the button
and drop your load. The sudden decrease in aircraft weight will give you
the extra performance boost you need to start climbing.

But, even IF the bombs were hot, it would be helpful if the bomb bay doors
were opened, first. g

Some/all B-17s will do that too. When Evergreen turned me loose in their
bird (flipped on the battery and open the bomb bay for some visiting WWII
vets) I was specifically briefed NOT to bump the landing gear lever or it
would be a very bad day at the hangar. I've had more than one nightmare
of doing just that since.

Did the B-17 not have landing gear locking safety pins to keep that from
happening once they were safely on the ground?

IIRC, the B-17 (and probably all other US bombers) had a safety cable across the
lower part of the bomb bay which would open the doors if a bomb inadvertently
dropped.

don't know anything about the cited incident but. Ever watch an older
mooney doing the gearup dip on takeoff? pulling that johnson bar takes your
attention off the flight attitude.

AIRCRAFT ON TAKEOFF, SANK DOWN ONTO RUNWAY WITH GEAR RETRACTED, FORT

Is this an example of putting the gear lever up before advancing the
throttle for takeoff?

Cessna gear (ie. an R182) folds under in such a way that drag is
increased during the retraction (or extension) beyond the level of drag
with the gear extended (or retracted, of course {8^). I've never thought
it that much that it would cause an altitude loss, but perhaps under the
right circumstances...?

Have not read the details, but I offer one vote for the cause being an
attempt to retract FLAPS and laying a hand on the wrong switch

Why do so on t/o that close to the runway?

The old 210's and skymasters were the same way. Once all of those doors
start opening, there is
a slew of new drag. An Ex-Boss of mine was demonstrating the squat switch
to a prospective buyer, when he retracted the 210 nose gear while sitting
firmly on the ground.

I don't believe so. The mechanism is jack screws, rather than hydraulic or
pneumatic, so they should not be needed.

I'm with the CO on this one. :-)

When you say "drop your load" do you mean drop the bombs?
Is it the decrease in weight or the exploding bombs that gave that
"extra performance boost you need to start climbing?"
