1
Q

When does the Initial Take Off Climb begin and end?

A

Begins at screen height (35ft) and ends at 1500ft

2
Q

What is the purpose of:

  • NADP1
  • NADP2

(Noise Abatement Departure Procedure)

A

NADP1:
- Used when the noise sensitive region is directly at the end of the runway

  • Aim is to reduce noise as soon as possible

NADP2:
- Used when the noise sensitive region is some distance away from the runway

  • Aim is to climb as quickly as possible to reduce noise by the noise sensitive region
3
Q

Describe the NADP1 including:

  • Heights/Altitudes
  • Speeds
  • Flaps
  • Gear
A
  • Start at screen height (35ft) at V2
  • Climb to 800ft, V2+10, TOGA, retract gear, flaps in T/O
  • Climb to 3000ft, reduce thrust, V2+10, reduce climb rate (still +ve), gear up, flaps in T/O
  • Climb (+ve), increase thrust, accelerate, retract flaps
4
Q

Describe the NADP2 including:

  • Heights/Altitudes
  • Speeds
  • Flaps
  • Gear
A
  • Start at screen height (35ft), V2
  • Climb to 800ft, TOGA, V2+10, retract gear, flaps in T/O
  • Accelerate to Vzf, climb(+ve), TOGA, gear up, retract flaps
  • Climb to 3000ft
  • Reduce thrust as and when required
5
Q

Describe the NTOFP (Net Take Off Flight Path) for a Class A AC including:

  • Start/end
  • Speed
  • Gear
  • Flap
  • Thrust setting
  • Max bank angle
A

Seg 1:

  • Start at screen height (35ft) and ends at spd: V2
  • Spd: V2min to V2
  • Gear retracting
  • Flap in specific configuration
  • Thrust: TOGA
  • Max AoB: 15 degrees (20 with approval)

Seg 2:

  • Starts at spd: V2 and ends at min 400ft
  • Spd: V2
  • Gear up
  • Flap in specific configuration
  • Thrust: TOGA
  • Max AoB: 15 degrees (20 with approval)

Seg 3:

  • Starts at min 400ft and ends at spd: Vmd and clean AC config.
  • Spd: V2 to Vmd
  • Gear up
  • Flaps retracting
  • Thrust: TOGA
  • Max AoB: 25 degrees (30 with approval)

Seg 4:

  • Starts spd: Vmd and clean AC config. and ends at 1500ft
  • Spd: Vmd
  • Gear up
  • Flap zero
  • Thrust: MCT
6
Q

What are the rules regarding turns in the NTOFP for a class A AC?

A
  • Turns can be commenced at a height >50ft or 1/2 wingspan (which ever is greater)
  • AoB must be <= 15 degrees below 400ft (Segment 1 and 2)
  • AoB must be <= 25 degrees above 400ft (Segment 3)
  • With special approval: <= 20 degrees between 200 and 400ft and <= 30 degrees above 400ft
7
Q

What is the minimum obstinate clearance for a Class A AC in the NTOFP?

A
  • 35 ft when AoB is limited to 15 degrees

- 50 ft when AoB is higher than 15 degrees

8
Q

For a Class A AC, what determines the maximum acceleration height in the 3rd segment of the NTOFP?

A

Maximum time take-off thrust can be applied (10mins one engine)

9
Q

For a Class A AC, what are the safety factors to be applied to calculate the net gradients during the NTOFP:

  • 1 Eng remaining
