When you within 20 nm from the Airport make sure you 210 knots. From 210knots its easy. Close the thrust levers.
Ask for Flaps 2. Speed 190 Knots.
Then Flap 5, Speed 160
Flaps 15, Speed 150.
At that stage you will need to apply thrust. Theres a VERY big changes in attitude from 210 Knots to Vref30+10Knots.
Use your Fuel flow. Bottom gauges as a ref. Its easier to look at. You will need 3000-4000kg if I remember correctly. if your speed it getting to low to maintain 250.
Then call for Flaps 25, Speed Vref30+10.
Flaps 30, Landing checklist.
On a 3degree glide you will have around 1500kg - 2000kg on the Fuel Flow.
Good Luck !
Attitude indicator and thrust is all you need.
remember what they looking for is to see you making progress in "learning on mistakes" during the session.
