Q

What is the difference between MTOW and RTOW?
…and when do we calculate RTOW?

A

Maximum Take Off Weight - The maximum weight in which an aircraft can ever take-off, under any circumstances, structural.

Regulated Take Off Weight - The maximum weight in which an aircraft can take off from a particular runway under specific conditions based on TOGA thrust (winds, weather, specific aircraft configuration, etc,). For example, runway 29 at KXYZ airport with ambient temp of 20° C. This can get as specific as you wish.

RTOW should be calculated using the ATIS and Mel items before completing the load sheet and verified against the F-PLN.

We then check that RTOW is below our actual TOW for that day. Otherwise replanning mag be necessary.

37
Q

Calculation for Required Landing Distance dry, wet and contaminated

ALD x ___ = RLD

A

Dry 1.67
Wet 1.92

If too many passengers go to the rear of the plane is could tilt.
Personal thought, get cabin crew to stop passengers moving from row 15 forwards untill rear half is gone.

44
Q

What could this Ecam caution mean whilst on the ground?
L/G SHOCK ABSORBER FAULT

A

Too much weight to the rear of the aircraft. An unstable situation.

A

Speed reference system

The SRS mode controls pitch to maintain a speed target equal to V2+10 kt in normal engine configuration. Single engine V2 or current speed, limited by V2+15 kt.

The SRS guidance law also includes:

Attitude protection to reduce aircraft nose-up effect during takeoff (18 ° or 22.5 ° maximum in case of windshear)
Flight path angle protection that ensures a minimum vertical speed of 120 ft/min.

Engages when:
Toga/flex set
V2 entered
Slats out
A/c been on ground for 30seconds

Disengages when:
Automatically at acceleartion altitude
If flight crew pulls for climb or pulls speed.

61
Q

First officer handling limits?

A

No PLANNED tailwind landings for 3 F/Os, if the conditions change after the commencement of the final approach the F/O should continue with the landing.

No Flaps 3 landing for 3* F/Os. This restriction is not applicable if an emergency situation arises that requires the F/O to conduct a Flaps 3 landing.

62
Q

What is the definiton for ‘actual landing distance’ and what dose it assume?

A

The Actual Landing Distance (ALD) is the horizontal distance necessary to land and come to a full stop from a point 50 feet above the runway surface. The demonstrated (flight test) landing distance is based on:

Final Approach Speed VREF.

A smooth, level, hard surfaced runway.

ISA temperature and pressure.

Brake pedals depressed at main landing gear touch down, and assumes the use of ground spoilers and antiskid.

No reverse thrust (unless otherwise stated).

What do we do if there is a fuel leak at engine start?

A

Run the engine at idle for 5mins.
No leak - we can dispatch
Leak - shut down and call MOC
