G Forces

[PilotCPB]

How easy is getting used to high g flight? I've done some civilian aerobatic flying, but never really done much beyond +5/-2 g or so. Just wondered how easy it is to cope with (think through complicated situations, approaches, etc.) and how often SNAs in T-45s get to go over 4 g or so...

G-onset in the T-45 is fairly gentle in my opinion....it doesn't load up nearly as fast as the T-34 (small swept wing vs large straight one essentially). Pulling g's is definitely an acquired skill. Even being out of the cockpit for a while, or being in something like RIs, I lost a lot of my G tolerance. Granted, it only took a flight to come back since my body was used to them. If you've never pulled G's, it will take a little while to come back. In the -45 you get to pull G's quite often. All through fams there are several 4G manuevers, but on your solo, you're limited to 'common sense' for the most part. I've been pulling 6 recently on the tail chase exercises in cruise forms.

The -45 has a g-limit of +7.33 above 5k and 6.5 below it. It's negative limit is essentially -2.3, but you don't often use negative g's except to unload and get some smack back on the jet.

honestly, when I'm the one flying, I never have to hick or really do anything to resist the G's. I think b/c my body knows when they are coming and that I'm doing it or somesuch... no idea. The only time I've had to hick is when I was trunking an ACM flight and we pulled 6.5. Since, I've pulled that and never had to hick, but I've been at the controls.

but remember, g's affect people in different ways, so your mileage may vary.....

What is a hick?

Preventing GLOC...

Ahhh yes....the hook manuever.
Here's a good web link to explain some anti-g basics.

The flights that seem to cause the most G related issues are when studs are trunking WEP's (bombing) hops. Not being able to control the airplane and at the same time being required to look behind the tail of the aircraft to spot bomb hits, while the IP is pulling G's, has caused more than one stud to "loose focus". It is very disorienting. Couple of the guys on this board can attest to that.

Maybe I'm just lucky, but aside from the fact that it squeezes you diagraphram(sp?) and makes it hard to breathe, the speed-jeans pretty much do all the work. I don't think that I have hicked or even tensed up my legs yet. I haven't been through WEPs or ACM yet, but I have pulled my fair share of Gs (my FAM solo was AWESOME!).

im an air hopefull for 188, and getting ready for flight training ive almost finished my private, i know that it will only help some, i also did a program that was based on emergency procedures, so we did up to 4 cordinated spins, inverted, chandelles, and various manuevors pulling g's to get ready, how much do you you guys getting jets think this will help if any?

 

[Banjo33]

I'm going into division forms any day now and I STILL sweat while strapping on the jet!

G tolerance is a perishable "skill". I think our advice is to not worry about it. You have a LONG way to go. You'll only be pulling 4.5 max in the T-34, and that's very manageable for most people.

 

[airwinger]

squeeze, you pulled 6 g's in cruise forms wow, you must have some pretty cool IP's. Heck I was lucky to get 4g's during tail chase...maybe coming up with "pipper's on" would have gotten more of a pull from the IP.

The G suit only adds about +1G to your sitting/resting G tolerance. I look at the G-suit as a reminder that "HEY!! You are experiencing G forces, you might wanna do something!" My resting G tolerance in the C-FET (in Lemoore) was something like 4.2 or so....

Consider G training like going to the gym and working out....the more you do, the better you can do them. The less you do, the less capable you'll be. So G-tolerance is a skill that can go away quickly if you don't practice.....that's why we do G warm-ups before any dynamic flight...it's kinda like stretching.

how exactly do you g warm in a prowler? one g to the right, 2 to the left? :icon_tong

I've heard about those awesome 2.5g breaks.

/just cursed myself to the Q's

 

[ea6bflyr]

Come on! I've done all of 5 G's in a Prowler....The pilot got his a$$ chewed. We were limited to 4.5G's....BUT I have done 6.5 (or so) in a TA-4 and an F-4....So there :icon_tong

But you are correct in stating that the Prowler is not known for it's G prowess.....but instead we run away bravely and let our forward firing ordnance take care of the threat....I'm talking about the 2 F/A-18's on our wing.

ps: what would be wrong with flying the 'double ugly'? At least you know for certain that you'll get a transition to Super Prowlers (EA-18G).

Besides dude, you've got a traveling spades game if you ever, er when you break down somewhere.

 

[petescheu]

the best part is contorting your body at 6-7 Gs in ACM will trying to keep your eyes on the dude you're trying to shoot... i have no idea how some of those IPs do it. good times...
