Once again, the regulations have been updated.

2014 Technical Regs
2014 Sporting Regs

The pages 73 and 74 show the changes for 2015, the survival cell behind AA is limited by:

"No part of the survival cell, nor any part rigidly attached to it (with the exception of the panel of prescribed laminate referred to in Article 3.7.9), may lie above a diagonal line starting 525mm above the reference plane at A-A and rising to 625mm above the reference plane at a point 375mm behind A-A"

This addition means that most survival cell shapes will have to change for the next season, the McLaren and Toro Rosso one could stay as they are atm.

Edit: Sorry, it seems i missed the part where it says "with the exception of the panel of prescribed laminate referred to in Article 3.7.9". This means that the survival cell itself has to change and be lower in that area, but a panel above is still allowed.
Dear FIA, if you read this, please pm me for a redesign of the Technical Regulations to avoid finger nose shapes for 2016! :-)

Regarding the nose of the car, how low can the nose actual be, with a nose like Mclaren or red bull? I understand the nose requires an minimum area of 900mm2, so why don't teams make it longer(vertically), so they can then make it narrower and still have the minimum nose area? This way more air travels under the chassis without being disturbed by the central plane of the wing

5.1.4. In the technical regulations specify that " Fuel mass flow must not exceed 100kg/hr"

I feel this is open to a lot of interpretation. Does a TD exist that further specifies it?

For example, under what period does a car have to achieve the limit? In it's current wording it could be interpreted as being possible to running above the limit for part of the measuring period if you compensate by running below it.

This opens up an interesting strategy in qualifying where teams could run with a higher fuel consumption above the regulated limit for the hot lap and then run a cold lap before returning to the pits.

My understanding is that 100kg/hr is a maximum flow rate , equating to a flow rate values of 27.7 grams/second or 13.83g/0.5sec etc...

The 100kg/hr would be used for qualifying ,but for a 1hr 40min race average, they'll have to reduce that to 60kgs/hr to finish.

Yes, that is how I THOUGHT it was, but reading the technical regulations it doesn't specify at all wether it is a maximum or an average flow rate. Hence it can be interpreted as being both.

The "must not exceed" implies that it's a maximum. If you average 100kg/h, by exceeding 100kg/h at some times then you have... well... exceeded 100kg/h.

Right, but it's stated as a flow rate of kg per hour which would imply a measuring period of one hour. Hence, you'd be complying to the rules if you had an average flow rate of 100kg over 60 minutes.

Why does that imply a measuring period of an hour?

If I want to drive at 100 miles per hour, do I have to do it for an hour before I can claim to have done it?

if I have understood correctly there is a Fia standard omologated fuel flow meter on board, is it correct?

They are on all cars, they are mandated.
Fixing points + FIA measuring points iirc

ohhh..... is it possible/allowed to make specific shape of the hole, thus could generate desired airflow ?
