Is there a single front door near cockpit in commercial planes for passengers and crew members for entry - boarding and exit out of the airplane ?.
If not do you feel there can be also a Rear door constructed near the tail wing in commercial planes ?. Is it feasible to construct a rear door ?.
The Rear door will be only for passengers who are boarding and exit out
of the airplanes while the Front door will be only for the airplane crew members including the pilot, copilot ?.
Do you feel a electronic panel can be constructed on the airplane Front door only for the aircraft crew members who are given identity electronic cards ?. The Front door will be opened only from inside and outside the plane when the electronic card is swapped by the aircraft crew member for entry and exit out of the airplane.
Do you feel this also be extended for the cockpit electronic panel door where the pilot, copilot has to swap the electronic card to enter and exit the cockpit ?.
Do you feel this may enhance security on the commercial airplane ?.
Thanks & Regards,

Answer The number of doors depends on the aircraft size. Airplanes up to about 15-20 passengers may have a single door, after that they usually have more. Small air planes often have just two doors but their is no set rule. Large commercial aircraft are required to be able to have all the passengers exit in a specified time.
In the USA FAR Sec. 25.801
(c) For airplanes having a seating capacity of more than 44 passengers, it must be shown that the maximum seating capacity, including the number of crew members required by the operating rules for which certification is requested, can be evacuated from the airplane to the ground under simulated emergency conditions within 90 seconds.
