To the guy writing the heli lesson diary:
I don't post here often but I have read w/ interest your diary of
flight lessons. A few questions if you don't mind: Why are you cooling down an R22 ( I assume from your threads that is what you're flying) for five minutes before you disengage the clutch? R22 checklists state a 2 minute cooldown before clutch disengage. The factory says it doesn't need even 2 minutes if you get substantial cylinder head temp reduction in less time. I cannot imagine a flight school allowing for one second more cooldown than is required by the factory. Unless you are paying for time on the skids, instead of collective time. If so, if you are paying for total Hobbs time, they may be screwing you, check it out. No R22 needs a five minute cooldown before clutch release. Just two minutes for coolodown, then release clutch for thirty seconds, then get mixture guard off and pull mixture out. Call Robinson Helicopters yourself and check it out. You may be asked for that additional cooldown time simply to run up your tab if you are paying for Hobbs time. Also, in one of your posts you state that after bringing the ship to a hover after an approach you had a wind gust that pushed the ship into a right yaw that was so extreme you had to add FULL left pedal to stop it. I've flown R22s for a while and I have NEVER approached the need for full left pedal. Ever. The R22 has very good tail rotor characteristics as opposed to some of the Bell's and others that can get you in trouble quickly with their less than ideal tail rotor designs that allow tail rotor vortices to form quickly in the wrong wind conditions, so I find it incredible that you got the ship so twisted that it was necessary for you to bottom the left pedal to get the ship back in trim. And that your CFI never took over??!!!!!! Maybe you just thought you used all left pedal? If not, get your ship checked out pronto, though I seriously doubt that you used all left pedal as you stated. Your CFI would have been on the controls very fast had this actually been the case or either he's wanting to get a new ship! You also mention "shimmy and shaking" all the way down during an approach. Are you getting into a settling w/ power situation? If you are experiencing violent shaking let me assure you this isn't normal. A little vibration for sure, but nothing like you are describing, or is this again a bit of exageration on your part? Not trying to provoke you here, as I have been there myself (learning to fly helis) and it can be VERY tense at times. It's just that this Google Rotorcraft forum seems to be frequented by mainly remote control helicopter enthusists and the Rotorway/Safari/experimental deathwish crowd that have very limited knowledge about flying and I would really want to make ceratin that a novice flyer like yourself will give an accurate account here so as not to confuse all the other readers here who have not became heli pilots. Please understand I'm not trying to ridicule or be derisive of your descriptions, I've been right where you are and I know the feelings very well. I'd just like to urge you to write a diary with less adjectives and bluster than what you are sometimes doing now. You are (inadvertatntly I'm sure)making it sound as if some of your flights are more akin to "The Right Stuff" movie footage than true flight training, especially the "full left pedal" and "shaking" stuff. Either that or your instructor needs to do a better job of instructing as I can assure you this is not the way it's done. Regards, Mark N26394 |
