Free ATPL operational procedures 071 questions: 7 with answers

The 7 questions

1. Question 1 · 071 01 General requirements

   The M.E.L. (Minimum Equipment List) is drawn up by :

   • Athe aircraft state of registry
   • Bthe aircraft manufacturer's list
   • Cthe operator
   • Dthe manufacturer
   Show the answer+

   Answer: C. the operator

   The operator draws up the aircraft-specific Minimum Equipment List (MEL), based on the manufacturer's MMEL.

2. Question 2 · 071 01 General requirements

   When the weather conditions require an alternate aerodrome to be available on take-off, the latter shall be located, for a twin-engined aircraft, at an equivalent distance not exceeding :

   • A2 hours of flight at cruising speed with single engine
   • B2 hours of flight at cruising speed with two engines
   • C1 hour of flight at cruising speed with two engines
   • D1 hour of flight at cruising speed with a single engine
   Show the answer+

   Answer: D. 1 hour of flight at cruising speed with a single engine

   For a twin requiring a take-off alternate, it must be within 1 hour's flight at cruising speed with one engine inoperative.

3. Question 3 · 071 02 special procedures and hazards

   Which one of the following sets of conditions is the least likely to attract flocks of birds ?

   • Along grass
   • Bshort gang-mown grass
   • Cedible rubbish
   • Dan area liable to flooding
   Show the answer+

   Answer: A. long grass

   Long grass hides predators and makes it hard for birds to see each other and feed, so it discourages flocking. Short mown grass, rubbish and flooded areas attract birds.

4. Question 4 · 071 02 special procedures and hazards

   When flying in straight and level flight at FL 290 for some considerable time a small leak develops in the cabin which causes a slow depressurisation, this can be seen on the cabin rate of climb indicator which will indicate :

   • Azero
   • Ba rate of descent of approximately 300 fpm
   • Ca rate of climb
   • Da rate of descent dependent upon the cabin differential pressure
   Show the answer+

   Answer: C. a rate of climb

   A cabin leak lets cabin pressure fall slowly, so the cabin altitude increases. The cabin rate of climb indicator therefore shows a rate of climb.

5. Question 5 · 071 02 special procedures and hazards

   Wake turbulence risk is highest :

   • Aif, just before landing a much lighter aircraft has landed at the same runway with heavy crosswind.
   • Bwhen a heavy aircraft has just performed a take-off at a closely situated parallel runway with a light crosswind.
   • Cwhen a preceeding aircraft has briefly applied take-off thrust just prior to take off.
   • Dfollowing a preceding aircraft at high speed.
   Show the answer+

   Answer: B. when a heavy aircraft has just performed a take-off at a closely situated parallel runway with a light crosswind.

   Wake turbulence risk is highest when a heavy aircraft has just taken off from a nearby parallel runway with a light crosswind that could drift its wake into the adjacent path.

6. Question 6 · 071 02 special procedures and hazards

   The transponder code to be used by an aircraft subject to unlawful interference (hijack) is:

   • A1200
   • B7700
   • C7500
   • D7600
   Show the answer+

   Answer: C. 7500

   Code 7500 is the SSR code reserved for unlawful interference (hijack). 7700 is used for an emergency and 7600 for radio communication failure.

7. Question 7 · 071 02 special procedures and hazards

   A tyre is inflated to 160 psi. Using the standard formula Vp(kt)=9×√(tyre pressure in psi), the approximate dynamic hydroplaning speed is:

   • A80 kt
   • B148 kt
   • C114 kt
   • D160 kt
   Show the answer+

   Answer: C. 114 kt

   Dynamic hydroplaning speed (kt) = 9 x square root of tyre pressure (psi) = 9 x square root of 160 = about 114 kt.
