Given the incident in the 210, do you really think that the OP's scenario of a fuel leak is so implausible?
Yes, I do, for reasons already given. Additionally, the 210 was operated at much higher speed, has a much thinner wing, and took a descent sized bird in a dive, causing the damage.
As I said, I've experienced a LOT of bird strikes on aircraft over the years. Most of them did little to no damage. The vast majority were fairly small birds, too. In most cases, the damage if any at all, was restricted to very small dents or dings in the leading edge; on several airplanes at one location I flew, we had kevlar leading edges installed to cut down on the dents and dings. In only a few cases have I had significant damage. You also have to bear in mind that much of my flying was done at low altitudes, where one has the greatest percentage of bird strikes. While you may operate in that environment for only a few moments, I may operate in that environment full time; it makes a big difference.
Some of those airplanes had reinforced surfaces, in some cases armored surfaces. The greatest damage I've had was the Lear strike, which did crush the radome and got the left windshield. I was also slowing through 250 knots at the time at 10,000' at night; circumstances in which the original poster will not find himself in a Cessna 152. In all liklihood, the original poster won't be spending all his time at low altitude working in situations that are conducive to bird strikes.
Bear in mind that few bird strikes occur at 3,500', which I believe was the original poster's postulation. Most occur below 500'. This has already been discussed.
While it's valuable to point out that any given birdstrike is unlikely to cause much damage, the point of considering emergency scenarios is to rehearse the thought process for abnormal situations, many of which are unlikely and unlucky.
The scenario posited by the original poster was very straight forward: a flyable airplane and an available runway. Really nothing to discuss; go land. The details were somewhat fantastic; multiple issues caused by multiple bird strikes, including the unexplained loss of the transponder. As noted before, even in professional training, we generally address one emergency at a time. For a student pilot to be positing multiple emergencies or abnormals all occurring at once is perhaps a bit much.
It's one thing to ask one's self where one will land if the engine fails. Fair enough; this is a requirement of every moment one is airborne in a single engine airplane, and it should be in the foremost of one's mind at all times. It's entirely another matter to begin imagining wild ideas involving complex scenarios; one leave the realm of productive thought to enter into unrealistic television drama. The what-happens-if-a bird-strikes-me-and-then-I-catch-fire-while-I'm-having-a-heart-attack-and-a-dozen-wasps-come-out-of-the-vent-to-attack-me-right-at-the-moment-I-realize-I-left-my-epinepherine-pen-in-the-car-and-the-iron-got-left-on-at-home scenario might be going a little overboard.
Here we have the I-hit-a-bird-ooh-it's-scary-everything's-fine-and-oh-look-there's-a-runway-I-can-use scenario. In other words, no problem. That's the important thing to understand here.
But none the less as I read that post, and thought about your other posts (small arms fire, instrument panels hanging out of the cockpit, engine failures galore), the thought crossed my mind that you must be the most accident prone pilot that I have ever come across
Small arms fire isn't an accident; it's part of the working environment. I believe when I wrote that I was working an assignment in Iraq, and shortly thereafter in Afghanistan. It's to be expected, you see.
The instrument panel was blown out of the cockpit, and that was a windscreen failure involving a rapid depressurization in a Cessna 421. There was no "accident," nor was I or anyone else prone to one. We returned to land uneventfully.
Engine failures, you bet. Most of mine have occurred in older large radial-powered airplanes; many of them were cylinder failures, some propeller failures, and a number of shutdowns due to large oil leaks from a weak point on one particular type of radial engine installation, involving the stephead governor mounting base cracking. None resulted in an "accident." Several years ago a single engine failure in a Garrett TPE-331-10 powered single engine airplane did result in a forced landing on a mountainside, which was not an accident and wasn't handled as one; I made the forced landing successfully and continued flying the airplane a month later.
None of the bird strikes have resulted in accidents or been accidents, either. In a few, rare cases, some damage has occurred which required repair. Otherwise, in most all circumstances, the bird strikes were uneventful. That's not to say that bird strikes are always so, of course. One causing a Cessna 152 wing tank to crack, that takes out communications, and that somehow disables the transponder is a bit unusual, but even then one has a scenario in which a perfectly acceptable runway is available and one has a full-functioning airplane with a good engine, good control, and an ability to go land. It's what one might call a no-brainer. Go land.
