Chapter 8 Operating Procedures

Question 1

What are the altitude corrections for non standard pressure or temperature?

Answer 1

Pressure: 30 ft per hPa pressure difference with ISA
Temperature: 4% for every 10 degrees C difference with ISA

Question 2

What is the minimum aerodrome category for the C750?

Answer 2

ICAO: cat 4
FAA: cat A

Question 3

What about Aerodrome Category inregard to non-passengers carrying operations?

Answer 3

It may be downgraded one category but must not be less than category 3

Question 4

Regardless of the obstacle situation at an aerodrome, what is the maximum allowed Takeoff mass?

Answer 4

The mass of the aeroplane shall not exceed that mass which assures a minimum gross climb gradient of 2,4 % in the 2nd segment (MAT-limit). For three engine aeroplanes, the minimum gross climb gradient is 2,7 % in the 2nd segment.

Question 5

Where does net take-off flight path end?

Answer 5

The net take-off flight path ends at 1500 ft AAL or when transition to final en-route configuration has been completed, whichever is higher.

Question 6

What is Procedure Design Gradient on which SID’s are based.

Answer 6

PDG of 3,3 %. However, certain SID’s may require a higher PDG due to terrain or obstacles. Prior using a specific SID on departure, it has to be verified that the required climb gradient can be maintained when experiencing an engine failure or special EFP’s must be established prior to take-off to assure terrain clearance when in IMC.

Question 7

What determines the maximum landing mass?

Answer 7

1. Approach climb (2,1% for two engine aeroplanes) or landing climb limits (3,2% for two and three engine aeroplanes).
   However, the PDG for missed approaches is 2,5 %, unless a higher gradient is required by the missed approach procedure.
2. Landing field length – LFL limits
3. Maximum structural landing mass

Question 8

What factor must be added to the actual landing distance to calculate the landing distance required for commercial flights?

Answer 8

67%

The estimated landing mass of the aeroplane at ETA must allow a landing from 50 ft to a full stop within 60% of the LDA.

Question 9

What factor must be added when the landing runway is wet?

Answer 9

When the weather forecast indicates that the runway may be wet at ETA, the LDA must be at least 115% of the Dry landing distance.
(1x1,67x1,15)

Question 10

What is the landing distance factor required for ferry, positioning, maintenance or training flights?

Answer 10

The landing distance available shall be at least 120% of the actual landing distance.

Question 11

What factor must be used for in-flight calculation of the required landing distance required?

Answer 11

15%

The In-Flight calculation (actual calculation) shall never be less than the distance calculated for dispatch purposes.

Question 12

What minima apply for MDA/DA?

Answer 12

If higher OCA’s/OCH’s are being published by state authorities (e.g. by NOTAM) and are higher than the DA(H) / MDA(H) shown on the IAP-chart, then those higher minima are applicable. According chapter 8.4 AWO, higher RVR/visibility minima’s may then apply.

EU-OPS type minima are published either on charts 10-9Z, 20-9Z, etc., or instrument approach charts with a STANDARD label on the minima box. If no such minimum published, the Jeppesen aerodrome operating minima as shown on the approach charts are applicable, provided they are not lower than the aerodrome operating minima published in chapter 8.4 – All Weather Operations.

Question 13

When do you needa Take-off Alternate?

Answer 13

If it is not possible to return to the departure aerodrome for meteorological or performance reasons.

Question 14

What are the considerations when choosing a Take-off alternate.

Answer 14

The take-off alternate must be located within 1 hour flight time at one-engine inoperative cruising speed in still air and ISA conditions, based on the actual take-off mass.
At ETA ± 1hr, the forecast weather conditions have to be at or above landing minima. When only non-precision or circling approaches are available, the ceiling must be at or above DA/DDA or MDA.

Question 15

Do you need a destination alternate?

Answer 15

For every IFR flight (except flights to isolated destination aerodromes), at least one destination alternate must be selected, unless: 1. Planned flight time from take-off to landing is less than 6 hours
and 2. Two separate runways are available and usable
and 3. At ETA ± 1hr, the forecast weather conditions indicate that ceiling is above 2000 ft or circling altitude plus 500 ft, whichever is higher and the visibility is 5 km or more

Question 16

When do you need two destination alternates?

Answer 16

When at ETA ± 1hr, the forecast weather conditions at the destination aerodrome are below planning minima AND
When meteorological information for the destination aerodrome is available.

Question 17

What is the maximum distance to any enroute alternate?

Answer 17

En-route alternate aerodromes shall be selected in such a way that a suitable en-route alternate is available within a distance flown in 120 minutes (EROPS: 180 minutes) at one-engine inoperative cruise speed for two engine aeroplanes.
For the Citation X it is determined at 590 NM.

Question 18

Which parameters are used to determine the one-engine inoperative cruise speed.

Answer 18

Yvjyv

Question 19

Which weather planning minima apply for the selection of the destination aerodrome and/or the take-off alternate.

Answer 19

At ETA ± 1hr, the forecast weather conditions indicate the aerodrome will be at or above the published planning minima as follows:
For precision approaches:
published visibility / RVR.
For non-precision approaches:
published visibility / RVR and ceiling at or above MDH.

Question 20

Which weather planning minima apply for the selection of dest. alternate, enroute alternate and isolated destination aerodromes?

Answer 20

At ETA ± 1hr, the forecast weather conditions indicate the aerodrome will be at or above

• Cat I RVR for Cat II or III appr.,
• Non prec. vis./RVR and ceiling at or above MDH for Cat I appr.,
• Non prec. vis./RVR and ceiling at or above MDH +200 ft/1000 m for non precision appr.
• Circling visibility Ceiling at or above MDH for Circling appr.

Question 21

Which VFR minima apply for training circuits?

Answer 21

Minimum visibility 2400 meters

Minimum ceiling 600 ft

Question 22

Which VFR minima apply for LSZS (Samedan)?

Answer 22

VIS 10 km,

ceiling 5000 ft AAL.

Question 23

In the planning phase, when are the weather conditions below minima?

Answer 23

If RVR, Vis or ceiling are below minima or the CWC above maximum.
BCMG, TEMPO und PROB40 must be considered.

Question 24

Which values for friction coefficient are available?

Answer 24

>0.40 = good
0.36-0.39 = medium - good
0.30-0.35 = medium
0.26-0.29 = poor - medium
<0.25 = poor

What is contained in the Taxi Fuel?

Answer 25

Fuel for:

• Engine start
• Taxi to the runway for departure
• Operation of ice protection systems
• APU consumption

Question 26

What is included in the Trip Fuel?

Answer 26

The required fuel for:

(TOC), via expected departure route
-Cruise from TOC to TOD, including any step

Answer 27

-the expected fuel consuption data.
-meteorological conditions
-planned routings and/or cruising

Contingency fuel shall be the higher of:

Answer 28

- An amount to fly 5 minutes at holding speed at 1500 ft MSL (company procedure) in ISA conditions.

Question 29

What is the minimum amout of alternate fuel?

Answer 29

From MAP to cruising level to landing at alternate aerodrome.
If two alternates are required, the fuel shall be sufficient to reach the alternate which requires the greater amount of fuel.
