Q

what is Vmcg parameters? when an engine is failed

A

when an engine is failed, it is possible to maintain directional control using only primary aerodynamic controls without deviating more than 25 feet laterally with all three wheels on the runway

Determined by
- engine at takeoff thrust
- Most unfavorable cg
- Trimmed for TO w/o exceeding 180 lbs of rudder force by pilot with rudder boost

Q

what is Vcefs?

A

Critical engine failure speed is defined as the speed at which one engine can fail and the same distance is required to either continue to accelerate to lift-off speed or to abort and decelerate to a full stop.

Q

What happens to refusal speed when there is a wet runway environment?

17
Q

what is emergency braking? P

A

Powered by stored nitrogen pressure

18
Q

Where do you find the chart on brake energy limitations?

A

section V of the dash 1

19
Q

What occurs at 8.1 million foot-pounds of brake energy?

A

Thermal fuse plugs may release, resulting in flat tires.

20
Q

What occurs at 14.8 million foot-pounds of brake energy?

A

Brake damage or failure may occur.

21
Q

How much energy is absorbed by the brakes per mile of taxi assuming flat surface?

A

up to 0.5 million foot-pounds

22
Q

How much energy is absorbed by the brakes per mile of taxi with a downhill grade?

A

Up to 2.0 million foot-pounds.

23
Q

What is the most likely cause of nose wheel steering failure and what should you do?

A

The torque link pin is not installed. STOP!

24
Q

In what instances would you abort a takeoff?

A

If the acceleration check fails or any system emergency affecting safety of flight is experienced prior to S1 speed

25
What are the steps to abort a takeoff?
Throttles - IDLE Wheel brakes - As required speed brakes - EXT
26
After roll-out from an abort what should you do?
Determine the reason for the abort and take necessary action. Check brake energy (if required) and accomplish the AFTER LANDING checklist. If the emergency is serious, evacuate the aircraft (emergency ground egress). Pilot judgment will determine the sequence of actions to be taken after an aborted takeoff. ## Footnote evacuate the aircraft (emergency ground egress). Pilot judgment will determine the sequence of actions to be taken after an aborted takeoff.
27
If runway length is insufficient during an abort, how should you engage the MA-1A type barrier?
Attempt to decelerate as much as possible and attempt to engage the barrier perpendicular and in the middle half at the slowest speed possible
28
If a malfunction in the anti-skid system occurs with an associated loss of brakes, immediately do what?
Place the anti-skid switch to the off position and attempt braking from both the pilot's and copilot's position. If braking is not restored, use the emergency brake system ## Footnote use the emergency brake system
29
How many emergency brake applications are available with full nitrogen?
7-10
30
Is it necessary to extend the speed brakes during an abort situation? Why?
Yes. It allows for the maximum amount of weight possible to be on the main gear to enhance braking efficiency.
31
In addition to extending the speed brakes during an abort, what else should you ensure to maintain weight on the main wheels?
Ensure yoke is in the neutral position
32
What happens to the brakes when they reach 430 F?
The thermal fused screws soften and blow out, releasing the air pressure in the tires.
33
Before a second takeoff is attempted (following an abort), the possibility of a second refused takeoff must be considered.
The cumulative effect of two refused takeoffs may exceed the brake energy limits causing tire explosion and fire, endangering the crew and aircraft ## Footnote endangering the crew and aircraft
34
What should you do if you expect hot brakes?
Notify ground, taxi to the hot brakes area and park the aircraft facing the wind. Do not taxi more than is necessary to clear the active runway. The aircraft should not be maneuvered into a crowded parking area. Do not set the parking brake. Do not approach the overheated brakes for one-half hour. Only approach from the front or rear.
35
What physically happens when we get hot brakes in the T1?
The thermal fuse screws soften and blow out releasing air pressure in the tires. The rotors and the pads may start to melt together as well. The brakes will need to be changed.
36
What happens when brake failure occurs?
The brakes mechanically fail and the aircraft will not have a means of stopping
