Isn't chocks on NLG compulsory in Germany.I Understand the Main Wheels are chocked but Shouldn't the Nose Wheel be chocked too.
If Im no mistaken the Nose wheel chocks are used for the Main Wheels.
Parking for a B737 should be more Aft.

If the aircraft is parked on a flat surface, only 1 of the mains really needs to be chocked. I worked at a big FBO this summer with a lot of private jets and the only time we chocked all three wheels was when a big storm was coming in. I don't know of any regulations regarding chocking in the USA or Europe, so I can't help you there, but I assure you that 737 isn't going anywhere until those chocks are removed.

Out here for a long halt as above,Minimum Nose gear & any One Main Gear is required to be chocked hence the Question.

Chocking policies are airline specific, not airport specific.

Actually when our 727 was operated for DHL in Europe A lot that is airline specific in North America Is airport specific over there. So it is not un heard of to have a rule on chocking.

Normally in Mexico the main gear and the nose gear got chocks, only when the plane stays all night we chock all the wheels
Life is what happens when you have other plans.....

At easyJet we only chock the nosewheel, but in windy conditions we sometimes chock the main wheels too!

The normal practice in Helsinki is chock the main wheels and nosewheel if the aircraft is parked on the remote stand. When those are parked at the gate usually only main wheels are chocked. However, some airlines have their own practices. For example, DHL and UPS demand that every tyre will be chocked (in case of B757 this means 12 chocks!).

In my mind it depends on aircraft type, what the manual says so to say.
For example the Lockheed Constellation manual says NOT to chock the nose wheel because it would damage the strut.
I suppose this applies to every type, just check your manual chapter "ground handling" and you will find the answer.
The truth lives in one’s mind, it doesn’t really exist

The picture could have been taken just before the chocks were placed, or just after they were removed. When no chocks are in place the parking brake should remain set.

Building codes applicable in most communities where you will find airports usually require the ground to slope away from buildings so that water will not pool up against them. This can produce a slight slope away from the terminal building. Again, that is community regulations, not FARs.

Also, as has been stated, chocking is in accordance with the airline's procedures.

If you'll notice, both the mains are chocked...

our policy on chocks is to only remove the ones you find that do not have a logo on them and put them in the ramp truck. We hate it when they punch holes to form a name

(fairs, fair our chocks go missing too, we punch holes but they still walk or should that be bounce they being rubber and all)

Hi Hawk21, Buzz here. If our aircraft (UAL) are at the gate, the parking brake is set and NLG chocks are all that's needed. When we park away from the terminal we chock the mains.

At UAL we have set the parking brake as long as i remember with no ill effects. I wonder why other operators release the brakes when they park?

Many years ago at SFO Service Center,on the old wash rack we'd park a 747 overnight. They seem to be light on the nose - at least when empty. One gusty night when the winds were crosswind to the old wash rack spot, the 747 squirmed over 5 or 6 feet, the NLG had been put on the centerline at the beginning of the night. By sunrise the NLG tires were 5 or 6 feet over as that Classic Lump had tried to weather-vane into the wind.
I'm a beliver in chocking the MLG...

"I wonder why other operators release the brakes when they park? "

I know continental have a park brake light at the external power panel (737NG) that operates even if all power is switched off, even the battery.
I believe they use the barless tugs and they don't use a brake man, so the tug can just come along and move the aircraft without using someone to operate the brakes.
The only thing they do is check the light and move it .
If it's not broken, don't fix it !

Parking brake is routinely left OFF whenever possible for a good reason. The brakes will cool better if they are not all clamped together (as in SET) If the brakes were very hot, leaving them to cool with the parking brake ON may warp the rotors.

Parking Brakes if set [B737] & power removed for halts more than 8 hrs require repressurizing & setting brakes as Hydraulic pressure will have leaked out by then.
Out here for long halts Both Main & Nose Gear wheels are chocked.
Why were the Main wheels chocked by Nose wheel chocks.

Chocking only the nose gear is a waste on time. Such a small percentage of the aircraft weight is carried by it. Would not take much for the plane to run right over it.

N867BX is right on the money. A stiff headwind can be enough to make an airliner jump nose wheel chocks with the small amount of weight that is on the NLG. Chock both mains if you want to be sure that the aircraft will go nowhere.

Out here Max Chocking of Two of the Four Main wheels & Both Nose Wheels is the SOP.I've never seen 10 chocks used on a B737.
Although We do see a few Foreign operators on charters do things differently.

High winds (30 to 40 mph) can and will turn a 737 around if not properly chocked and brakes applied. It just happened a week ago a EWR. A 737 got twisted around almost 180 degrees so that its tail was facing the terminal and nose facing out towards the taxiway. I don't have the details, but I know that this isn't the first time it happened. By the way, the aircraft got lucky and sustained minimal wingtip and stabilizer tip damage.

Your Right this has happened many times before.Unless the Steering Metering valve is locked,or Main Gear chocked.The B737 when unpressurized can cause the Nose wheel to turn with strong winds.Something similiar happed at Delhi a few yrs back.

As far as general aviation operations go, I've seen both methods of chocking. We've flown a Cessna 414 for years and generally do not chock the mains except when parking overnight. If high winds are forecast, the airplane usually gets tied down using the three tiedown points. Due to the aircraft design (low wing to ground clearance) there really is no safe way to chock the main gears immediately after engine shutdown due to the location of the engine exhaust piping so the plane usually gets a nosewheel chock and tied down on the two engine nacelle points instead. There are a few other GA aircraft that have similar design concerns.

There are chocks available that chock the Two nose wheels [Longer width] which are very effective,compared to the Single wheel ones use on the MLG.
Im refering to the ones used on B737.
