Take off with heavy loads

Recommended Posts

Hi,

 

I'm unable to TO for the FAM flight from the BFM campaign.

 

I check:

* Flap Full

* +3° AOA with gear extension

* Trim +8/9

 

However, for each TO I deviate left of the runway and can't efficiently control the aircraft with rudders.

 

For TO:

* slow drive to align the F5 and the nose wheel

* Apply brakes

* Throttle full MIL

* Release brake at 85% full MIL

* Maintain the nose wheel button

* AB on

and crash along the runway ...

 

I can land in heavy configuration without trouble, even when I brake.

 

I can TO with light load.

 

What I'm missing ? Training ?

 

Thks

Ensure dampers are on.

Ensure Air Brake is in.

Ensure Flaps are at Auto.

Ensure nose-wheel is hiked.

Set correct trim setting (see here https://forums.eagle.ru/showpost.php?p=2974281&postcount=17 )

(+3 deg AOA doesn't actually do anything ref TO, its just an instrument)

Line up carefully.

If brakes on, go Throttle to near max before releasing although I find no brakes is just fine.

Anticipate deviation from centreline and apply lightest touches of NW steering up to 60 kts to keep straight.

Remember NW steering is 'direct' like a car steering wheel and you need to bleed off the rudder as you ease back to the line, probably correcting a little to get on centre.

Use Rudder above 60 kts (may require larger inputs when still slow).

Anticipate when to come off rudder.

Rotate around 165kts - 180kts and before 230 or risk tyre blowout.

I think you have a box to check in the controls section once you click into the "axis tune" box with the rudder control highlighted. You have a button to check for "inverting" it, which makes them the correct way. Lemme get into my controls to verify, but I remember my pal who walked me through my set up having me do this.
