When does speed change from IAS to Mach?
At FL260
Is the tropopause uniform in height? If not, what height is it at the pole and the equator?
Is the tropopause uniform in height? If not, what height is it at the pole and the equator?
No, tropopause at the pole is lower (30.000ft) than at the equator (56.000ft)
What is VMBE?
What is VMBE?
The maximum brake energy speed.
It is a function of the gross weight, altitude, temperature, runway slope, wind component, and braking configuration.
V1 must be less than VMBE.
What is the critical angle of attack?
What is the critical angle of attack?
The critical angle of attack is the angle of attack which produces maximum lift coefficient.
This is also called the "stall angle of attack".
If you only have a compass, which is easier to navigate along: a line of longitude or a line of latitude?
If you only have a compass, which is easier to navigate along: a line of longitude or a line of latitude?
A line of latitude.
Why do you need contingency fuel?
Why do you need contingency fuel?
Contingency fuel is carried to account for additional enroute fuel consumption caused by wind, routing changes or ATM: ATM/CNS restrictions.
Can you explain to me what Mach tuck is?
Can you explain to me what Mach tuck is?
Mach tuck is a nose-down pitching moment experienced as an aircraft passes Mcrit.
Mach tuck is a form of longitudinal instability that is caused by the centre of pressures rearward movement (caused by the shock wave) behind the centre of gravity.
What is RVSM?
What is RVSM?
Reduced Vertical Separation Minima (RVSM) is the reduction, from 2,000 feet to 1,000 feet, of the standard vertical separation required between aircraft flying between flight level 290 (29,000 ft) and flight level 410 (41,000 ft).
You are on a flight from Stansted to Amsterdam and just after T/O you are at your cleared level of 2000ft when you have a complete radio failure. What are your actions?
You are on a flight from Stansted to Amsterdam and just after T/O you are at your cleared level of 2000ft when you have a complete radio failure. What are your actions?
First continue on the SID and try all available resources to check if you have a complete radio failure.
If so, squawk 7600 and return towards the airport.
What is a VOR? What frequency range and band is it in?
What is a VOR? What frequency range and band is it in?
VHF Omnidirectional Radio Range (VOR) is defined as VHF Omnidirectional Radio Range, an aircraft navigation system operating in the VHF band.
VOR's are assigned radio channels between 108.0 MHz and 117.95 MHz (with 50 kHz spacing); this is in the very high frequency (VHF) range.
