Dispatch Release

Question 1

How long is a release valid

Answer 1

Two hours

Question 2

Give two reasons why a pilot must amend or obtain a new release

Answer 2

Aircraft Change

Delay greater than two hours

Flight unable to depart using old release

Return to departure airport

Unscheduled landing

At the discretion of PIC or Dispatcher

Question 3

When must a takeoff alternate be listed on the release?

Answer 3

When weather at departure airport is below mins for lowest approach

Question 4

What are the applicable restrictions with a takeoff alternate

Answer 4

For two engine aircraft, this alternate is 1 hour from departure airport at normal cruise speed in still air with one engine inoperative

Question 5

When is a destination alternate required

Answer 5

1, 2, 3 rule

No instrument approach at destination

OR when any of the following happen…
Freezing precipitation at destination
RCC less than 3
Airport in Alaska that has only one suitable runway

Question 6

How can you determine if the destination alternate is legal?

Answer 6

If the visibility is at or greater than the lowest approach at that alternate

Question 7

When does a release require an additional alternate airport?

Answer 7

The exemption 17347

When both the destination and the alternate are marginal

Question 8

What is MINTO fuel and how is it calculated?

Answer 8

Minimum takeoff fuel.
Allows you to fly to destination, then furthest alternate, plus 45min.

enroute
alternate
hold
plus reserve

Question 9

How is release fuel calculated?

Answer 9

Minto plus contingency plus taxi out

Question 10

How is planned reserve fuel calculated?

Answer 10

45min at 15,000ft at 250kts.

Minimum is 2450

Question 11

How is holding fuel calculated?

Answer 11

planned landing weight at destination at 10,000ft

Question 12

What would a Sabre Windshear value of > 07 indicate on the release? Considerations?

Answer 12

On the release under turbulence advisories
0-2 no turbulence expected
3-4 light possible
5-7 light likely mod possible
>7 mod likely severe possible

Question 13

Where is your planned TOC with respect to the tropopause? Why is this important to note? (Have students identify tropopause using the max wind levels on the release).

Answer 13

Trop is found under the MWL.
Trop represents a region of very stable air. When mtn wave interacts with the air breaking gravity waves may form. This results in moderate to severe turbulence.
Lenticular clouds typically form at the crest of a mountain wave

Question 14

Why is it important to reference filed true airspeed during flight?

Answer 14

To be able to check if we are burning more or less fuel than originally planned

Question 15

Are all MEL, CDL, and NEF items required to be listed on the release?

Answer 15

No, just MELs and CDLs

Question 16

If an aircraft item is deferred after block out and prior to takeoff, is the deferred item required to be reflected on the release?

Answer 16

When determined that the deferral affects aircraft performance, or restrictions may be imposed on the flight the release must be amended. If not…. a new release is not required.
