What is density height at PH 6000 feet and 20 deg ?
6000 + (120x17) = 8040 feet density height
What is density height at PH 12000 feet and 0 deg ?
12000 + (120x9) = 13080 feet density height
What is density height at PH 3000 feet and 30 deg ?
3000 + (120x21) = 5520 feet density height
What is density height at PH 2000 feet and 2 deg ?
2000 - (120x9) = 920 feet density height

Given that the empty aircraft weight and moment index is 1250 lbs and 109.64 respectively, determine if it is safe to fly with the following load distribution.
Engine oil: 15 lbs
Fuel: 25 US gallons
Front seats: Pilot and passenger each weighing 150 lbs
Rear seats: Two passengers weighing 155 lbs and 130 lbs
Baggage: 20 lbs
Is it safe to fly ?
Unsafe
An airfield has an elevation of 2100 feet. On a day when the QNH is 1002 hPa, the pressure height of the airfield would be closest to
Select one:
2100 feet
2430 feet
1770 feet
1900 feet
The correct answer is: 2430 feet
A Bravo type aircraft has a BEW of 1320lbs and a moment index of 110 index units. If the pilot and co-pilot have a combined weight 425lbs, a passenger in row 2 weighs 225lbs and they wish to carry 25lbs of baggage, what is the maximum amount of fuel that may be carried?
Select one:
190 litres
190 lbs
141 litres
222 lbs
The easiest way to solve this is to see how much weight we have available to us with all of the passengers, crew and baggage loaded. From that we see we have a zFW of 2010lbs. That means we could add a maximum of 190 lbs of fuel to get us up to MTOW of 2200lbs for Bravo. We should check those figures on the graph to ensure we are within the CofG envelope. Remember, with Bravo, if you are inside the envelope at ZFW you will not go outside the envelope by adding fuel unless you go over MTOW.
The correct answer is: 190 lbs
An airfield has an elevation of 3000 feet. On a day when the QNH is 1025 hPa, the pressure height of the airfield would be closest to
Select one:
3000 feet
2460 feet
2640 feet
3600 feet
The correct answer is: 2640 feet
An airfield has an elevation of 750 feet. On a day when the QNH is 1009 hPa, the pressure height of the airfield would be closest to
Select one:
630 feet
870 feet
1100 feet
750 feet
The correct answer is: 870 feet
An airfield has an elevation of 45 feet. On a day when the QNH is 1010 hPa, the pressure height of the airfield would be closest to
Select one:
-45 feet
550 feet
135 feet
zero feet
The correct answer is: 135 feet
A Bravo type aircraft has an all up weight of 2100lbs and a Moment Index of 196. There is 100lbs of baggage in the baggage compartment. The minimum amount of baggage that must be removed from the baggage compartment to get the aircraft in balance is closest to:
Select one:
30lbs
10lbs.
70lbs
None – the aircraft is in balance.
When you plot the all up weight on the CofG envelope you can see the aircraft is loaded with the CofG too far aft, outside the aft limit. To bring the CofG forward, we are told to remove baggage from the cargo compartment. Start be taking all of the baggage out and seeing where that puts the CofG.
Once we have a new point inside the envelope, we can see where the line crosses the aft limit and read off how much baggage needed to be removed to get to that point. About 30lbs in this case.
The correct answer is: 30lbs
You are cruising in Class G airspace on a magnetic track of 297 degrees. There are scattered clouds with tops at 6000ft. The lowest VFR cruising altitude available to you, above the clouds, would be:
Select one:
8500 ft
7500ft
6000ft
6500ft
You are above 5000ft so you must adhere to the hemispherical cruising level rules for westerly tracks. This means cruising at of even thousands + 500ft. You are in Class G airspace so the standard VMC conditions apply to you which means you must maintain a vertical separation of 1000ft above and below clouds. Therefore the lowest cruising level available to you above the clouds will be 8500ft. (AIP ENR 1.7 5 & 6 or see the VFG)
The correct answer is: 8500 ft
Consider the following conditions:
Pressure Alt: 3000ft
Shade Temp: 9oC
Take-off weight: 950kg
Runway: 14
Surface: Long, dry grass
Slope: 1% down to the NW
Wind: 140oM at 5kt
Using the Type 1 take-off charts, the take-off distance required is closest to:
Select one:
790m
700m
720m
900m
We will be using runway 14 which runs towards the Southeast. If the runway slopes 1% down to the Northwest, that means it slopes up to the Southeast. Therefore if we use runway 14, we will have a 1% up slope. In real life, or in questions where the runway to use is not specified, you may need to consider if there is an advantage to taking off on the reciprocal runway to make use of the downhill gradient. You would only consider this with problems describing a wind of up to 5kt since the maximum permissable tailwind for the aircraft is 5kt. In this question though, we were told to use runway 14
The correct answer is: 790m
